Well thay look great, the build quality is awesome they work in small sealed enclosures and I bought the 2 12's for 155.00 each brand new on Ebay!

None

Well I debated getting these subs for a little while just beacause I wanted to be different,and I know they are popular! So I have no regrets I'm pushing my two 12's with a bridged Orion XTR 800.4 and they are getting near 500 watts each! I also have a Lightning Audio 1 Farad Blue Striker Digital cap so that helps! No weakness they just hit hard and loud I had a custom made sealed box out of 3/4 MDF and doubled MDF on the sides it is a little bit bigger then 1.0 cubic feet! I did this to help the SPL, but if you read the Infinity specs it says 1.0 lined withe fiber fill so they actually will work a little better in slightly bigger box! thay clean power the XTR is a great amp for these subs it was chosen over the MTX Thunder 1000D just because I thought THD,and sound quality is more important then all that extra power of the MTX!

Hit low and incredibly hard!

Rattles the trunk too much in my altima

I have had an extensive amount of experience with this speaker and all I can say is that they sound better than anything I ever had.I was sitting in my yard with it turned up one day and my mom told that the shelves were fallin off the wall inside.They're great speakers to say the least.

price - thank god for ebay!
sound quality
SPL (yes it does both quite well)
looks - its beautiful, white aluminum
doesnt need alot of power to hit hard

i need earplugs and need to find a way to keep my rearview/sideview mirrors from shaking so much

this has GOT to be the best sub out there, for its price class. i've never heard anything hit lower or harder, or more cleaner for a single 12". Im driving it with planet audio P275 (250 watts continuous) and a lightning audio cap. Before this i had a kappa 12, svc, and i thought that was impressive...this beats the living sh*t out of that! Infinity couldn't have picked a more suitable name for this sub, it truly is PERFECT

kappa 12/1 svc - good, but nowhere near as loud or clean

their plush appearance and very deep lows. they got what i call SEXY BASS

will blow when push to the max but they come w/ a 3 year warranty so have fun w/ em

ihave these 2 subs running of 1 punch 500 and they sound magnificent. they are definitely the best sounding 12's on the market. i was disappointed with their rms potential. their peak handling is a bit deceptive but i definitely recommend them to anyone who appreciates good deeeeeeeepppp bass

Great sound quality, loud, accurate

The stupid tinsil leads broke off and i had to reattach them, but they fixed the problem for the new ones, also they aren't very loud outside of the car

I am a very experienced installer. I run a stereo shop called Premier FX and used to do all the installs. I recently installed two perfect 12's in my car and was amazed at the sound. The quality was of 10's but they were as loud as 15's. The best of both worlds. I had 750 rms of clean power to each and that was about right, maybe a little overkill. Infinity recommend a 1.0 cubic foot box, but dont listen to them. They sound MUCH better in a 1.25, i tried every size and found this worked the best. As to the people who say they blow easy and they suck, they obviously don know what they are doing. If installed properly and are run off a high power CLEAN amp they will last a long time.

anything you can name

These things are amazing. Those who don't agree need to re-evaluate it. These things hit hard as hell and rattle my car like crazy. I've had my rear-view mirror fall of 4 times in a couple of months. I run 3 Perfects with a RF 800a2 wired in parallel for less resistance. This system is perfect and will win competitions with 1/2 volume. Definitely a great buy. Go to Ebay and find Scala1 and buy from them. Great response time and good service

Absolutely nothing

Excellent. Must Buy if you're willing to part with some $ for the Quality

Nothing compares to these

These subs are really efficient and have no comparison in spl in my opinion. Great Bang for the buck!

If you beat them up you'll break a tinsel lead at the binding post. The aluminum cone dents relatively easy. As with any long throw woofer they aren't really as accurate and tight for SQ.

I own the 10's, but have had 9 months of selling them to gather my opinions on the 12's. They'll get louder than anything I've aver heard thus far. I'd bet they could reach 150db in the right car in a ported enclosure @ 50hz. Great spl subs I'd whole heartedly recommend them to a bass freak! Over all though, on a musical scale, judging on accurate music reproduction they aren't my favorite.
