Infinity PR6510CS Primus Series Automotive Component System


About this item Patented Plus One Polypropylene Woofers – Polypropylene cones with up to 35% more radiating cone area than other cones in the same class provide higher sensitivity, increased low frequency output and better tonal balance. Edge-Driven Tweeters – Edge-driven tweeters deliver wider dispersion and smoother high frequency response with increased power handling for high- and mid-frequencies. True 4 Ohm Architecture – True 4 ohm architecture with low impedance voice coils give the amplifier room to deliver peak power providing stronger and clearer sound with better depth and detail. Infinity speakers have to undergo a testing process that would destroy lesser speakers. Infinity freezes them, bakes them, shakes them, blasts them with ultraviolet light and drives them at full power for days at a time. Voicing of Speakers – Speakers are individually voiced to assure high quality audio versus “off-the-shelf” manufactured sound. This means that specifications as well as speaker characteristics are considered when tuning the Infinity sound.

    I put these in my sisters 2010 Honda Insight. Very easy to install. They sound loud and crisp. Excellent quality. But they lack bass. The stock speakers sounded muffled but had more bass than this. If you are someone who doesn’t mind missing bass or are planning to add subwoofers. These are excellent speakers. Make sure you use the sponge like tape around the metal rim of the speaker to make sure it won’t rattle. The tweeters sound very clear and the quality is amazing.

    Excellent speakers, put them in the front doors, they kick ass. Great highs from the tweeters and great mid range from woofer. Infinity makes a great product

    These speakers kick for the price. I installed them into an Acura TL with factory radio. The speakers are very underpowered without an aftermarket amp, however they still sound great! I deadned the entire panel and around the speaker for airtight mounting and the clarity is fantastic, I can now hear my music!They are listed on Harman website as a 2.7ohm speaker which is good for factory radios to get the most db per watt. But the listing on here says 4. But rest assured they are 2.7 and they kick!

    Got these speakers to put into my 2014 Ford Focus hatchback. Reason I chose this particular model is because it runs at a lower but safe 3 ohm. Meaning, it’ll pull more power from the factory amp to boost the volume which was lacking with the factory Sony 10 speaker system. Volume is much better with these. Pic is of the door install.Install was time consuming but simple. Some install write-ups I found online says to reuse the stock speakers housing by gutting the stock speaker from it’s plastic surround. I just used the ones that came with this product. Fitment worked great. Used sound deadening on the doors and hot glue to secure the crossover to the vapor barrier.Sound Quality is great. My only complaint as others have mentioned is the crossover. The tweeter isn’t adjustable Db +- as I’ve gotten on other builds I’ve had in the past. It makes the tweeter sound kind of harsh, atleast to my ears. I had to adjust the stereo EQ to lower the treble quite a bit. Woofers sound very good although seems to bottom out at maximum volume. No complaints to my untrained ear.Overall, very satisfied with the purchase and would recommend to others.

    The 6.5 speakers that come in this set are absolutely amazing! I have them paired with top of the line skar audio tweeters and crossovers. I havent used the tweeters or crossovers but they seem of excellent size and quality

    These changed the whole sound of my car. I have a crunch p1400 powering the front components and another 1200 pushing my alpine 12 sub. I have the level set kinda midway and it’s perfect. They sound good even with the sub off. Even the bass hits hard. I replaced my polk audio with these and they hit

    I’ve had these installed in my 2018 Kia Soul 1 Million Edition for a little over a month now and I’m nothing short of impressed. I do have an aftermarket speaker amplifier and your mileage may vary if that is necessary. I’ve had many different brands of speakers over the years from Kicker, Kenwood, Memphis, etc. And these by far are the most crisp sounding speakers and it’s well worth the money. Some may complain that there is a lack of bass but they aren’t supposed to have that. Components are not meant for bass. You have a subwoofer for bass and lower frequencies. I really am happy with the way the perform and would buy them again.
