Infinity REF-6502ix 2-Way Reference-X Series Coaxial Speakers with Edge Driven Tweeters, Set of 2

These speakers have great sound. Full range from a thumping bit of bass to great mids and clear highs. They sound fine from a decent aftermarket or modern OEM head unit but even better when I put a small 50w amp on them. They come with a bracket to help fit in a variety of situations and adhesive backed foam cutouts to help with vibrations. Highly sensitive and great for replacing door speakers from the factory.

Used these to upgrade my awful 5 1/2 in speakers in the rear doors. These speakers, unlike most Inifinity speakers, actually have good mid-bass response. I heard them in store and loved them, for the price you really can't beat it, I don't think there's a comparable product in the same price range. Top notch. Installation is a breeze with the provided brackets, they will fit ANY car make and model.

For the money... RIDICULOUS BARGAIN. I went from a very hi-end $3,000+ car stereo that I had to sell and since I was not using an actual amp for the front speakers anymore, I was looking for something that would sound decent and play loud, not be too expensive and most importantly would run OK without an amp - right off the deck. My deck is a decent Alpine HU, maybe 20-watts x 4. I am using a pair of these in my doors where a set of $1,300 Dynaudio components used to be (each powered with a 250-watt monoblock amp). These sound really, really good for the $65 or so I paid for them. NOTE: at first, they will sound too bright, but give them some break-in time... they do warm up. For bass, I kept one of my Diamond Audio amplifiers and am running it to a 10" Rockford Fosgate P3, shallow woofer in a small, sealed box. The setup sounds amazing for how little I have into it.

Bass is pretty bad but everything, literally everythign else is absolutely golden. pair these with a subwoofer in the back and you are golden.

Sound is very clear and very clean. A little less bass than I expected but that could be for a number of reasons with my system. Still perform very nicely especially for the price

I really like these speakers. They replaced the stock Bose system in my car and these sound even better. I'm running them off an Alpine headunit (50w x 4) without an external amp and they sound great. This is a 2-way system with built in tweeters and crossovers. The tweeter is adjustable so you can somewhat aim them toward the listening area. They also include a treble boost button in case you need a little more than your radio puts out. Installation was fairly easy using the included universal adapter....the hardest part was removing the rear speaker deck! I love the Infinity brand (I have a 20 year old pair of home speakers still sound like new) and their dedication to quality. I compared these in-store to more expensive Polk's and I liked these better.

I've had good luck with Infinity speakers in the past, and these were no exception. They are higher quality than some of the other Infinity components, have a very smooth sound, and reproduce accurately. The crossover is very smooth and the tweeter is not harsh sounding.

I purchased and installed 4 speakers to replace the original Infinity factory ones in a 2009 Kia Optima. The sound quality throughout is outstanding with using just the original head unit from Kia. I've been listening to music through Infinity speakers for about 10 years now. Would definitely recommend the Reference X Series speakers to anyone looking to upgrade sound quality in their vehicles.
