To Infinity, and Beyond Your Normal Woofer

Don’t let this 8 inch Infinity Reference subwoofer fool you; it has no problems pumping out deep, clean bass when you’re tight on space. At 1000 watts of peak power, it takes the heat without stepping out of the kitchen. All of this without sacrificing sound quality or cutting sensitivity.

Infinity’s product quality and excellence stem from their passion for music. This fact is evident in each of their lines, with no exception to their Reference Series subwoofers. Whether you listen to rock, hip-hop, jazz, country or anything else, these woofers will shine through with every note. High-gloss polypropylene woofer cone is lightweight which assures maximum efficiency which produces high output with modest amplifier power. This in no way means the Reference woofers don’t have a sound quality side, far from it. Sound quality is the name of Infinity’s game, and every beat will be smooth, crisp, and hard hitting. The large-roll rubber surround absorbs distortions that travel through the cone, ensuring clean bass response. Vented polepieces help cool the motor structure which allows for an increase in power handling. Engineering at Infinity is state-of-the-art and a great deal of computer aided design software is used to devise their products. This commitment shows in all of their product lines, and with such a good reference, it’s a no brainer.

I hooked up two of these along-side an MTX 9500 15". These were hooked to a Rockford Fosgate r1000 giving each ~550 watts. (only because my friend let me borrow his before he gets two more)

Upon adding these, all the mid-bass my 15 couldn't reproduce, is back.
These subs alone sound cleaner and deeper than my 15 (Not anywhere near the spl, silly) but the three of them really shine because they just don't have the low extension like a 15. After adding them, I definitely feel cabin-pressure I didn't have before. In the trunk of a fully-deadened 2002 grand prix (oh and what difference sound proofing makes)

HUGE HUGE HUGE output from these 8's. More than any 8 I've ever heard. Definitely comparable to two CVR 12s in SPL with a HUGE improvement in sound quality.

I've never gotten good results from mixing woofers, ever, but in this case, it sounds clean and articulate, and accurate at low levels.

Someone looking to just add near-perfect bass without rattling their car should look into running these babies UNDER their RMS cause the output from one is just too much if THAT'S the sound you're going for.

Thinking about running 8 tuned at 29 hz.

I have 2 of these in a 2005 F150 crew cab. Im running them each on 300 watts of old school alpine v12 power... all i can say is amazing sound. They handle everything i throw at them and ask for more. If you are looking for a sub this size, there is non better.

My buddy is running four of these in a 3 cu ft sealed box wired at 1 ohm to a hifonics txi750 to break them in. In a 2003 Saturn Vue.

Man these sound cleann~

They're extremely punchy and accurate in the sealed setup crossed over with the fronts so well, you can't tell where they roll off -- exactly how it should be. From outside his car, his his hatch doesn't rattle at all, but from inside his car, the bass is powerful enough to move my shirt about a 1/2 inch. These are definitely louder than my MTX 9515 despite being a hell of a lot cleaner.

He's ordering 3" aeros and tuning the box to 34 hz and getting a Soundstream TX1.2000 feeding each sub ~400+rms after box rise.

I'll post an update on how this setup sounds. He's also contemplating running 8 of them off that same amp.

I ordered that Infinity for my 2010-Lincoln Navigator, I replaced factory basic sub and put this with 2 Channel AMP. Ohh what a bass and deep quality sound. I advice who want a good and quality sub sound in their car. Don't waist your time and pick that. Quickly easy-thirsty shipping too. Thank you.
