Infinity Kappa Perfect12.1 Car Subwoofer

Pros: Pounds HARD. Looks sweet.
Cons: FLAWLESS

This was my second sub to own and will be with me for a long time. The first sub I ever bought was a Polk DX. The sound was so horrible it made me research for about 6 months to find the best sub so the experience would not be repeated. Someone...

Pros: Great sound, plays low and loud. Looks beautiful
Cons: No longer as advanced as when it was introduced

These subs play VERY low in a sealed box, and have the ability to put out pretty impressive levels of bass. I installed one of these in my friend's Sunfire running off an Infinity Beta Digital 100 (400 x 1 rms) amp in a 1.25 ft^3 sealed box. She just ...

Pros: Sound, Power Handling, Appearance
Cons: None

This sub is by far the most impressive sub I have ever heard in a car that costs under $500. One of my friends has 2 12" hooked to a RF bd1000 and he is pushing 145 db at competitions. I only have one 12" hooked up to a RF 360a2, giving it near the...

Pros: Performance, reliability, appearance
Cons: What?

My first sub was an Infinity Reference 10" which I was really impressed with. I found it quite difficult parting with it after it had provided so much quality sound. This was until I upgraded to the Perfect twelve. After much research into top line 12"...

Pros: good price quality sound
Cons: not a one

Man if you want quality go for this Infinity. I loved it from the first bump!. So clear so loud and so worth the $300. If you are serious about sound and want to have a system that makes your friends jealous and your Grandmother wet her drawers, then...

Pros: Looks. performance, quality
Cons: Nothing

The Infinity Perfect is a very highly regarded subwoofer. It's very nice looking, and sounds excellent. I have a JBL 600.1 hooked up to it, giving it 300 watts, and it has nice tight bass, and gets extremely low also. I've been into car audio for about 2...

Pros: Sound Quality, Performance
Cons: price, but maybe not!

My car, like most cars out on the road today, had a rather horrible stock sound system. So I decided to upgrade. Now many kids today, when they get subwoofers for their cars, don't care how it sounds, as long as it's loud. They want "thump"....

Pros: looks great
Cons: no power handling

I had it for 3 days and the filaments burnt up. Repaired that and then the voice coil melted. I only ran 285watts rms to it. There are better subs for the money out there. It did have great SQ and good bass extension but it just dosn't handle the power...

Pros: Sound amazing, looks great wouldn't have nothing but Infinity
Cons: Too big for my car

Infinity Kappa 12in subwoofer are one of the best sounding speakers I have ever heard. Never had any of them blow like I have with other company's, if it was up to me this would be the only speaker company that should make them there's no dought about that. I have compared them to friends stereo systems and they also agree that they should have chose a different company, these are compition speakers to me I would have no problem putting them in one and being confident

Pros: Great, deep, responsive bass. Superb warranty. Amazing punch. Impeccable quality. PERFECT!!!!!
Cons: NOT one that I can think of. I didnt buy them sooner! ;-)

I just recently purchased a pair of Perfect 12.1's and I must say I am superbly impressed. I am pushing them with a Viper 1200.1 and I must say they handle at least 450W clean as ever. I originally was shooting for JL W6's or Alpine Type X's but everything I've read about these speakers made me sway. Infinity has always been synonymous with nothing less than the best quality and they did not slack here! They beat low and loud! Crutchfield has them buy one get one free w/ free shipping so $180 out the door is definately a deal! Out of the 90-something reviews I have read about these subs NO ONE has anything negative to say!

Pros: Clean, tight bass, very effective even in sealed box.
Cons: The cone material scratch easily, it's aluminum so protect your sub with a good grill.

What a good sub! Only one in a 1.0cu ft sealed enclosure installed in the trunk of my hatchback and I can believe how much presence this sub have! Got a pair of Infinity 6˝ coax. in the rear and a pair of component in the front, all hooked up on a 111w RMS x 4 amp, the sub is alone on is 283W RMS Infinity amp and It can stand making the bass for the whole system even in is sealed box! My old 10" was just not enough. Bass is clean, tight, can handle very low frequency without showing sign of weakness. I bought mine used on ebay for 50$, already broke up so It begin playing awesome at first listen.

Pros: Well built, amazing sound, and a true SQ sub.
Cons: People in prison.

I have these running off a 600.1D Lightning Audio Storm and these things sound amazing. The clarity and low bass it hits is unbelievable. I was thinking to get some Alum12, Kicker CVR, or Alpine R's and believe I made a good choice with Infinity. There were some reviews were others said they blew after a few days or weeks. If you are running a 1000 RMS to each with the gain past full blast, then yes they will blow. They are more SQ, with some nice SPL. Not deafening, but very good. Music sounds like music with these and not to mention I run the comp 6000cs for fronts and rears 6002i, all Infinity. Also with a Clarion DXZ825 these subs are absolutely amazing. Run no more than 400 RMS
and you will just fine.

Pros: Accurate sound, quality & reliability, audiophile specs., aluminum cone, heavy-duty basket. Good value too.
Cons: What, cons? Maybe not the speaker you need for a tiny enclosure, but that's all!

Having previously owned only 4" Infinity components, I wasn't familiar with their subwoofers-but I knew of the reputation for quality; even their Reference series was above the average cookie-cutter brands out there. I sold my 2 MTX Black Gold 10" subs. and picked up a Perfect 12.1 used but in great shape. Nice speaker! Has great numbers where it counts: low total Q (Qts), power handling, and good physical construction. Definitely worth the money. Listening to pop, rock, or just average "contemporary" music is very enjoyable with the substantial low-end the 12.1 provides. Solid sound performance: "sharp" bass notes, with excellent reproduction of your sound source. Performed quite well with my Planet Audio hybrid vacuum tube amp with sealed MDF sub enclosure. I can't complain, and can't wait for more! It's hard to live without once you've owned one. Mine came with spec. sheet, usage recommendations, and foam edge seals. I think I'll have this one for a ~long~ time.

Had sub for 2 years. Wire's from terminal broke. Resoldered wire but keeps breaking. What a shame. Sub looks brand new. Now throwing it in the garbage.

These are GREAT speakers and I would readily recommend them to anyone who is interested in the best possible sound for their car. I have a $2000 system and while it aint much, the Infinitys are some of the best speakers that I have heard(keep in mind I'm some what of an audiofile). For this price they cant be beat and to get a nice step up from them plan on spending another $150-200 per speaker. The frequency range is great through out and the clarity is phenomenal. I put mine in the recommended size box and while it is lound enough for me (1 running off a MTX81000D) I think it would be better to put it in a larger box. (rockford makes some of the better airtight boxes you can find)
