Excellent affordable speakers at Jasko I had broken the factory speakers (paper or cardboard material) to replace my '97 Integra, so I went to the store to listen to different speakers under $ 100/pair. Polk was DB651s was totally No. 1, but this Pioneer surprise, better than the Infinity and Sony (there are also those under $ 100/pair speaker) sound. Polk had a clear and balanced sound from bass to midrange to high. These speakers were so clear, however, was not balanced. So I decided to sit down, Polk speakers front and Pioneer in the rear. Surprisingly, I could not hear, get to see much difference when driving, probably because of all the noise on the street. TS-G1643R speakers sound 1000x better than the cheap factory speakers - I do not know if you can buy something bad as what they put into the factory. Pros: - Installation was really easy. You need to get an adapter cable to "use" for your car, place the speaker on one side and lift adapter on the other side, then put back the original screws and that's it - the sound is excellent - you can hear good bass and clear sound for both listening to music or radio. - It's so cheap is hard to imagine how you can sell and make money. Pros: - After placing the speakers, the sound may not be what you expect - usually do not get enough bass. After changing the speakers have to use your receiver and equalizer set to sound you like. In my case, I restored the default setting JVC receiver (all "0") and added four db "bass" and-2dB "high." So this is not really a "con" but a note has to do something "extra." For decent speakers to replace cheap factory junk, no competition in this price range of these speakers. 17 of 18 people found this review helpful. Yal speakers very well this is just a great speaker all round Well done. Increases very, very good and nice deep bass. Love them! The efficiency of the speakers you need to seal the speaker the right to maximize. I bought some rugs air conditioner filter foam and cut to fit around the edge of the speakers (I used removable sealing window that feels a lot like Playdoh to seal my face). I used the foam on the edge of the purchased space where it meets the door. Which completely seals the rear of the front of the speaker and the bass increases, at least 30 times, and increases efficiency and life of the speaker. Especially in the door speakers! Hope this helps someone! 9 of 9 people found the following review helpful. When the bass Marginal bmwrider Tinny sound compared to Honda Odyssey factory speakers. Supposedly it is "30 Hz" speakers, but they do not say that the response of the speaker to 20 dB at 30 Hz, the cutoff is real 3 dB 90 Hz depending on the reaction of the graphics package on the package when you are on looking for bass, forget it with this speaker. Good mid and high frequencies, however. All 47 customer feedback ....

Infinity Reference 6032cf 6.5-Inch 180-Watt High-Performance Two-Way Speakers (Pair)

Looking for a more moving audio experience? Take Infinity car audio for a ride. Innovative materials and breakthrough engineering have always put Infinity products out in front of the competition’s. So expect extreme output from these speakers, but be prepared for accuracy and detail that may surprise you. Infinity Reference Series loudspeakers continue to be the top-selling premium speakers in the world. For instance, the 6-1/2-inch Reference coaxial model has been the number-one-selling car audio multielement speaker for five years straight. With proprietary features such as patent-pending Plus One cones, true 4-ohm topology, UniPivot edge-driven tweeters and the industry-leading Intermount III and I-Mount mounting systems, as well as the Starfish tweeter-mounting adapter, Reference Series speakers leave the competition scrambling to keep up.

Amazon Sales Rank: #1094 in Car Audio or Theater Brand: Infinity Model: 6032cf Dimensions: 5.00" h x 5.00" w x 10.00" l, 5.00 pounds 6-1/2-inch two-way loudspeaker with 180 Watts peak power handling and 2 Ohm impedance Plus One woofer cones and durable rubber surrounds for increased bass output and higher efficiency Edge-driven textile dome tweeters for increased power handling and reduced distortion at high output levels Tweeter level adjustment and swivel positioning for optimizing sound and stereo image One-year warranty

Infinity's 6-1/2-inch 6032cf is a two-way loudspeaker with Plus One woofer cone and edge-driven textile dome tweeter, and offers an ideal--and simple--upgrade to your factory drivers. Infinity's Unipivot tweeter can be pointed toward listeners even when the speaker is mounted off-axis, for a an optimized stereo image. The Infinity Reference Series Infinity's Reference Series has been engineered to deliver best-in-class performance for those looking to replace or upgrade their factory speakers. Features like Infinity's Plus One (patent pending) woofer cones and edge-driven-dome tweeters have helped position Infinity Reference as the number-one line of automotive loudspeakers for the past six years straight. An ideal upgrade to your factory drivers. Infinity 6032cf Features Plus One woofer cones This patent pending technology deliver a cone with more surface area than competing models of the same size. The result is increased bass output and higher efficiency. True Four Ohms All Reference speakers feature two ohm voice coils. Original factory-installed speaker wiring in many cars is 18-22 gauge. This wire, and heating in the voice coil when power is applied, increase the impedance "seen" by the amplifier or head unit. The impedance of Reference Speakers has been adjusted to compensate for this increase and can be safely driven by any head unit. Edge-driven textile dome tweeters These are not commonly used w-domes, but fully-edge-driven domes like those found in better home audio speakers. The benefit is increased power handling and reduced distortion at high output levels. This technology also allows for better integration with the mid/woofer. Unipivot Infinity's Unipivot (patent no. 6,002,780) allows the tweeter to be pointed at the listener's location even when the speaker is mounted off axis. This optimizes the stereo image and ensures a more uniform response. Tweeter level adjustment The 6032cf also features a tweeter level adjustment located on the front of the speaker and can be set at the reference level of 0dB. If the speakers are located low in the doors or if you are looking for a brighter sound, set the tweeter at +3dB Rubber surrounds This material provides optimum cone-edge suspension and absorbs distortions that may travel up the cone edge, adding stronger low-end. Infinity 6032cf Specifications Power Handling, RMS: 60 Watts Power Handling, Peak: 180 Watts Sensitivity (2.83V @ 1m): 93dB Frequency Response: 53Hz - 21kHz Impedance: 2 Ohms Mounting Depth: 2-1/16 inches (52 mm) About Infinity Infinity was founded in 1968 on a unique blend of technology, performance, and design.

Customer most helpful reviews 5 of 5 people found the following review helpful. Large speakers to replace the speakers in a 2001 Odyssey LX OEM Markus Berndt I just installed Infinity 6032cf speakers in the doors of our Honda Odyssey LX 2,001th The suit, however, have to cut the plastic tabs protruding from the plastic adapter including mounting clips and two plastic and a plastic edge of the door used to customize the OEM speakers to make the adjustment assembly adapter. Then I had to cut some of the plastic inside the door to make way for the largest magnet speaker Infinity. The speaker connector can be easily disassembled Honda so that no pressure connectors required (originals are in the Honda connector can be used). The grills covering the speakers will still fit after Infinity 6032cf speakers were installed. As for sound, I am very pleased with these speakers. To put my opinion in perspective, I'm not the kind of person who needs an amplifier and subwoofer to worry about other drivers with their music was just looking for an upgrade to the OEM speaker terrifying version of the Odyssey LX 2001 . Infinity 6032cf speakers actually a very significant improvement in the quality of the original sound through the speakers. Especially the low risen much 'and included tweeter to deliver high very clear. I would also mention that I use the original OEM Honda car cassette radio. 14 of 18 people found this review helpful. This is the replacement of the factory-set taaays you! From Silverleaf installed in a 1997 Jeep Grand Cherokee with the infinite. Installation is straightforward for a family car Junky. The sound is full of a 6.5 and an excellent substitute for the factory speakers. On my ZJ, copper cables as with all my means, I gently sand to remove oxidation and adhesive residues before welding of the contacts. I was not impressed by the small negative reports, it is clearly labeled to the terminals to distinguish the size is not necessary. There are a number of cats outside my window with angry sex. It sounds hilarous. The foam absorbers includes a sufficient job of reducing vibration, but goes a bit far Dynam. You may need to drill through the plate for the correct installation of these speakers. Something to think about a DIY. Has anyone ever driven through Lancaster County, PA? It smells like poop there. Unfortunately, high while writing this. 2 of 2 people found this review helpful. Good speakers when set up correctly by Cameron First, I have a Pioneer DEH p5200HD main unit and a 4,400-watt amplifier that provides SSL at 50 watts RMS at 4 ohms per channel. These speakers were a little difficult to install because I did not come with any hardware to the speakers with the universal adapter mount, but when I found some bolts and nuts and after a small loop around the place where the screws in through they fit nice and extremely efficient Pros: - 2-ohm operation. I love that through the speakers, less resistance means more watts for them that makes them better than my Kenwood 69 in the back - Swivel Chairs treble I have no great difference in the tone of these shows Tweeter fell on me, but I can not complain and the fact I know they have assured me, though I could not tell, some of the switch on the treble, how much higher it got. - These speakers can be very strong and have excellent and worthy of time (see cons) Cons: - Not having the hardware supplied was not a great achievement for me since I had some spare bolts around, but if not a little inconvenience - One of my biggest complaints about these speakers is the bass response when applying these serious HPF distorted in a rather low volume, which surprised me. Fortunately, most of my bass is provided by my 6x9, but not 200 Hz HPF I have in my amp I would not be able to use almost half of what these speakers have to offer. I think 100 or 150 Hz HPF can also work.

They make great speakers OEM parts for your speakers blow. You are not at all heavy or bassy. They are great for normal everyday listening level. Since then I have returned after switching to a different higher production to meet my personal needs and listening preferences. But above all I will suggest these speakers to those who just want to get rid of your factory speakers blown or replace them with something that will get a clearer sound. Chief Audio makes good products and I will always be impressed by their products, and continue to use. 1 of 1 people found this review helpful. CEO change? Why? JET speaker is measured by the width of the outer cone. This is measured through the house! Do not fit as you expect if you are replacing factory speakers! I recommend sticking with the branded products for the replacement of most of them cost more but worth the money. In addition to greater variety in terms of their application. Never buy speakers of this manufacturer again. 1 of 1 people found the following review helpful. If you've read the comments ... By Kevin If I had read a critical opinion of California, would not have bought the speakers. I wanted to replace my 25.5 "(measured by the cone) speakers in my Nissan Frontier. Like the other reviewers said, the total width is 5.25", including the edge of metal. Not even close to what I needed. Site not to say that they fit into a 2001 Nissan Frontier. Should provide guidance on how to measure the speakers. See all 5 customer reviews ....

By Ryan McDermott These things are absolute shit, Im a mechanical engineer and attend college full-time mechanic I installed probably two dozen sets of speaker parts in my life these are the worst I've ever seen, no speaker I've seen is anywhere near the bass that I consider these speakers, first, let me draw your attention, which are sold in singles. A speaker of a car that I saw are not sold in pairs ... They do not come with hardware, no wiring, nothing. I bought a pair of 6x9s and 6.5s do not think I need anything special just a cheap parts original, I do not understand. What I have four completely useless pieces of garbage. Right out of the box broke and got into what I consider normal hearing level forces me to listen to them at half the volume of my music normally heard cases at the end of the week, was even low volumes of every size, quite other two barely audible. Just save your money and buy something that works. I just bought the Polk Audio equivelants replace them, and is nothing short of astounding. I spent 60 in four of them with shipping and 130 in Polk with shipping and would do it again every time. Would not pay $ 10 for a set of four, spam. See all 1 reviews ....

Mirage Omni-S8 8-Inch 400 Watt High-Performance Subwoofer

The Omni-S8 is a compact class-leading 8" powered subwoofer which packs power and finesses into a small enclosure, filling your room with incredibly deep and defined bass. The 400 watt amplifier (100W RMS) precisely powers a high-excursion 8" Titanium-Deposited woofer featuring our patented our Ribbed Elliptical Surround technology, providing deeper bass and lower distortion than ever heard before in this size subwoofer. The Omni-S8’s slender cabinet is constructed of rigid medium density fiberboard, to minimize resonance and distortion, and finished in a Black Ash vinyl. Pair the Omni-S8 with the immersive sound of any of our other speakers and experience home audio entertainment like never before, or add it to any system for major sound improvement and a foundation of deep-down bass. This Omni-S8 is small and well-priced, but don't be fooled by its value, the technology and performance.

Amazon Sales Rank: #19564 in Consumer Electronics Color: Black Ash, Platinum trim Brand: Mirage Model: Omni-S8 Released on: 2010-03-05 Dimensions: 15.30" h x 11.70" w x 14.60" l, 27.50 pounds Compact, class-leading 8" subwoofer produces precise deep bass down to 27hz! 400 watt Amplifier (100watt RMS) precisely matched to woofer for accurate and high-impact bass Heavy-duty 8" Titanium-Deposited woofer & down-firing low-turbulence port Patented Ribbed Elliptical Surround Technology for lower distortion & greater dynamics Variable high-pass filter, phase switch, line-level and speaker level inputs for easy integration with any system

Omni S10 Overview If you want home theater entertainment that really grabs your attention and puts you on the edge of your seat, then you need our Omni S8 subwoofer to anchor your speaker system. A solid design with exceptional value, it creates truly immersive music and movie experiences. In order to produce bass of seismic portions, the Omni S8 packs advanced materials and exclusive technology into one exceptionally designed enclosure. And, while this sleek, compact subwoofer is good at making you feel thunder, it won’t steal it away from your precisely placed décor. You’ll find it neatly tucks away in a corner or under a table, out of direct view. Benefits Powered front-firing design with a down-firing port creates amazing bass performance Sleek black finish and compact design easily integrate into your lifestyle 8-inch woofer with patented Ribbed Elliptical Surround delivers true depth without distortion Front-panel level, frequency and phase controls simplify listening adjustments Rear high- and low-level inputs increase connection flexibility Detailed Description - How Low Can You Go? The Omni S8 is the smaller model in our Omni subwoofer lineup. It gets its hard-hitting intensity, with near zero distortion, via a newly developed amplifier that can produce 400 watts of dynamic power and 100 watts of RMS power and a high-output 8-inch driver with a patented Ribbed Elliptical Surround. This proprietary design eliminates surround dimpling, enabling the subwoofer to play lower with greater output and fidelity. The subwoofer’s down-firing port further increases its output by using the floor as a loading surface. In fact, the Omni S8’s frequency response goes down to 27Hz, so it sounds like a much larger subwoofer and sets a new standard in its class. On the Omni S8’s front panel you’ll find three controls: level, frequency and phase. These accessible controls let you adjust your bass levels with complete ease, as well as facilitate the subwoofer’s acoustical integration with the other speakers in your system. On the back of the subwoofer, high- and low-level inputs, as well as a power mode selection increases both installation and connection flexibility. There’s no denying that the Omni S8 will bring powerful, tight and undistorted deep bass performance to any of our home theater systems; however, we recommend pairing it up with our Omnisat®, Uni-Theater® and Nanosat product lines. The Science Behind the Mirage Sound: Exclusive Mirage Technologies Ribbed Elliptical Surround Technology Our patented Ribbed Elliptical Surround technology (U.S. patent #6,725,967, Canadian patent #2,407,123) increases excursion, eliminates distortion and raises efficiency on our woofers and woofer-midranges such as those in the OC-45. While a speaker surround (suspension) permits cone movement, our proprietary Ribbed Elliptical Surrounds permits identical movement in both directions for near zero distortion and improved resolution. Our Ribbed Elliptical Surrounds also allow for a more cone surface and greater peak to peak movement than conventional designs, resulting in greater efficiency. These attributes enable our woofers and woofer-midranges to move more air with less distortion, ultimately allowing them to play lower in frequency with greater clarity and dynamics. This is especially helpful in smaller or slender speakers, like the OC-45, by providing better dynamics and lower distortion (attributes normally associated with larger speakers) while being easy to blend with subwoofers for a more seamless system. Specifications System Type: Powered Front firing Subwoofer with Down firing port Amplifier Power Output: 100 Watts RMS, 400 Watts Dynamic Power Frequency Response: 27Hz-120Hz Woofers: 8" woofer with ribbed elliptical surround™ Variable Low Pass Filter: Yes Inputs: Low Level, Stereo High Level (Speaker Level) Dimensions HxWxD (inches): 14.5 x 11.8 x 15.4 Dimensions HxWxD (cm): 37 x 30 x 39 Weight: 29 lbs. lb / 13.4 kg Finish: Black What the experts are saying about the Nanosat® CC… “The Omni S8 packs an incredible amount of value into its compact, affordable package. Its sound delivers with an exclamation point, over all types of music, home theater, and gaming material, providing a terrific combination of weight, punch, speed, and detail with only minor flaws that never detract from the presentation. 'Tight' is the word that best describes this product - while it may be missing a couple features and a smidge of ultimate fidelity, it delivers so much for the price that you barely notice. The Omni S8 is an extremely formidable contender in its price bracket, and must be auditioned by all shoppers anywhere near it.”- Home Theater Review (June, 2010) Goodsound, Great Buy Award (October, 2005)

It's perfect for small rooms and apartments, mainly because it does not shake images on the walls, but it fills the sounds wonderful. The down is SOOOOO CLEAN. Great sub sound. I've had 10 "subs you get from the CC and Bestbuy to less than 2 accounts and they are junk. Look around and you can probably nab it for less than $ 300. 13 of 13 people found the following review helpful. Secret weapon for a good home theater Timothy Medora course, there are many other subs out there. There are other, cheaper, bigger, more powerful. The beauty of the S8 Mirage? I turned, tweaked the controls are very flexible for 5 minutes and have virtually left alone since then. It just works. I still hear the sound strained, heard it bottom out, or notice a difference in one layer in some way. It lurks in the shadows until it is required, then the challenge that I love both movies and music. I am a big fan of the design of the sleek and compact. The S8 is a good way to fill a room of small to medium size with deep bass. 4 of 4 people found this review helpful. Nice, tight sub. Good for small and medium-sized rooms. Try cheaper. By Ed J. Hayes, I do not buy this from Amazon. I paid much less than the full price and I feel like I'm in the big bin at an affordable price. On the full selling price ($ 368), there are too many sub-woofer and consider only one of them. Many U-boats well, taking off $ 300 - $ 350 range and can be a difficult choice. Price aside, there is a great sub for a small to medium size room. I find it very musical. It is not sloppy with the music and hear a variety of things keeps my house. This is a heavyweight Mirage satisfied with the movie too, especially if you raise the upper secondary level to the film (but usually leave at default on my receiver) I can feel the vibrations in the action scenes in the movie without problems, and this is my little guy can rattle the walls if I put high enough. Do not let the driver 8in out unless you have a large space to fill. VELODYNE sub and Hsu are both beautiful with 8in drivers, and both brands are good sub too. This sub takes time to break into (the manual says 50 hours and that seems right). I found after a few weeks, I had again run the calibration of my receiver, it slowly crept down as sub charger broke in fully recommend this if you can get for less than full retail. At full retail stores, is still a great sub, but you might want to make sure that you like on another for the price. See all 11 customer reviews ....
