Got enough juice? Get an amp for your new sub The Infinity Kappa Perfect 10.1d dual voice coil 10" subwoofer teams up a rugged aluminum cone and high-roll butyl-rubber surround for massive, accurate bass all the way down to 18 Hz. The super-rigid woofer cone won't distort (even when you push it hard), but it's light and responsive for remarkably high sensitivity. That means it'll squeeze the most volume out of the power you feed it.

The rock-solid cast-aluminum basket and the pole-piece are vented, so the 4-layer voice coil stays cool even when the music gets hot. Infinity has subjected these subs to the most intensive testing in the industry — 100 grueling hours of performance at their full RMS rating (350 watts).

The dual 4-ohm voice coil design allows you to wire your sub for high output (2 ohms) or for multiple subwoofer configurations (8 ohms). The Perfect 10.1d bridges the gap between subs intended for SPL and those intended for sound quality, creating bass that hits hard and sounds great. Whether you're planning a competition system or just looking for powerful bass, this sub's ready for action.

Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible. Most car amplifiers are stable down to 2 ohms in standard mode, or 4 ohms in bridged operation.

Priced per speaker

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Great Subs

Written By Jaymes, Ohio on Thursday, April 27, 2006

i have 2 of these subs in my 04 ford f-150 supercrew and they are pused by a zx750.1 amp...When i first got these subs, i had quite a bit of problems.... I was getting alot of distortion and a lot of air leaking through my box.... after using silicone to seal around the suba to make sure no more air was coming out... i was still getting distortion, and iwasn't even turing my gain past 2!!! I worked and worked on my subs trying to figure everything out, but nothing was working... so i finnally rewired my speakers to what is called a series connection, and now they pound....and now i can crank my amp and and give them more then 50 watts of rms more then each speaker can handle and i still have no distortion i couldn't be any happier with them... the best part is the longer they run the louder they get... its great..i would recoomnded these subs to anyone who wants great clean bass with but have little room to work with....

BIG sound small package

Crutchfield Customer Review (What's this?)

this is the first major sound purchase in 15 years. this sub is the center piece of an all infinity kappa system. unbelievable is all i can say. the bass is very tight and very strong. the longer it is played the better it sounds. unfortunatly i only have enough room for 1 in a small sealed box. i would recommend this sub to everyone who wants tight clean bass but does not have allot of space. again unbelievable

Kicks Hard and Clean

Written By ModernGrowl, East Coast on Tuesday, February 21, 2006

Crutchfield Customer Review (What's this?)

Hits hard and clean. It brings out detail on the bottom end I've never heard before, all while thumping my chest with pumping kick drum hits. I have 2 of these in a sealed .65 enclosure and running 250rms to each. This is all I personally need. From this setup, I get hard hitting, kick. (I listen to heavy rock/metal) Not only tight low-end kick, but also clarity and cleanness I haven't heard with my previous 2x10 sub set up. The bottom end detail is greatly improved as well, much more then I thought I would get. Thumbs up!

Infinity Kappa Perfect 10.1d

Crutchfield Customer Review (What's this?)

This sub is awesome! I have an F150 supercab with a Qlogic custom box which fits under the rear seat. I had been running an Infinity Reference sub with an Alpine MRP-M350 amp. The level of bass was ok but lacked the punch I was looking for. Talked to one of the advisors (Oscar) and he recommended trying a dual voice coil sub which increased my amps power from 200 to 350 watts. We selected the Perfect as a replacement. The output is what I was looking for but the change in sound quality absolutely blows me away. This sub is so deep and the bass is tight. Makes me wish I had room for one more.

Super hard Hitting and the CLEAREST SUB I have ever heard!!!

Written By steven02_35th, Texas on Friday, July 15, 2005

Crutchfield Customer Review (What's this?)

I have heard a lot of systems, all different kinds, i put this sub in my 2002 SLP Camaro SS and it hits so hard with an infinity reference 611a Mono amp powering it, it has lots of power, but this sub is different from most as it has more power than most, but with as much power as it has and how hard it can hit... it is by far the clearest sounding sub i have ever heard before, NO distortion or bad vibrations at all... Be sure and seal your box and pookie it very good for the best seal... also force your own screws into the box after the sub is in place. If you want one of the best subs for the money and clearest sound with hard hits, go with this sub, I WOULD NEVER GET ANY OTHER SUBS BESIDES INFINITY PERFECT NOW THAT I HAVE ONE!!

Infinity Kappa Perfect 10.1d

Written By daniel, redmond WA on Sunday, May 08, 2005

i bought this sub 2 summers ago, and i have never gotten tired of it. every time i get in my truck, i cant wait to turn it on. i hooked it up with an audiobahn 4-channel amp, and bridged it to the sub giving it plenty of power. basically, this sub is worth every penny i paid for it, and if i ever upgrade my system i am definitely getting another.

One word.....AWSOME! This subis the absolute best I have ever heard.I've heard audiobahn, kicker, alpine, and many more subs and this one is absolutly the best. I have a SINGLE cab Ford Ranger with a tiny enclosed box and it will either keep up with other subs or beat them. I have 400 watts going to it from an Infinity 610a amp. Seriously this sub is a true monster.

I just received this sub a few days ago! One word W-O-W high quality sub! Sounds great, no distortion or rattling like I hear with other subs.

Sweet Sub.

Written By Ryan, Marion County,TN on Thursday, March 31, 2005

Crutchfield Customer Review (What's this?)

I bought this sub around a year ago, and have it in a fairly large vented box. I have it wired just to one voice coil a 4 ohm load and pushing it with an audiobahn8000T amp pushing 400rms to it and have it fairly well turned up and it takes every bit of it and when i crank it up it does not distort at all. I only have one 10" and it hits really hard. I'm going to take it out of the vented box and put it in a custom built ported one and see if that makes it hit harder. For anyone who is looking at this sub i recommend it, It is an awesome sub.

Big Bass, Little Package

Written By Boss, San Diego, CA on Wednesday, March 02, 2005

I got one of these subs a couple months ago, put it in a small sealed box and have loved it ever since. I'm about to get a second one and put them in a ported box. I'm feeding it 400 watts rms from my Hifonics Zeus amp and the bass is phenomenal. If you want the best SQ, get this sub

Bass Out The Wazoo!!!!

Written By Justin Harris, Kodiak, AK on Sunday, February 27, 2005

Crutchfield Customer Review (What's this?)

I Bought this sub after basically waiting for 2 years to actually get one! I can say that I am thoroughly pleased. Even before it was broken in I was getting complaints from neighbors HAHA!! This sub produces the Lows better than any sub I have heard, I have friends who have 2 12 inch subs in their vehicles, yet my 1 10 inch powered by a 900 watt Lightning Audio Amplifier can demolish their systems! If you are looking for a moderately priced sub with a Accurate, Crisp, Clean reproduction this is the sub for you! Now I am going to trade it in for a 12.1d!!!! And I will be sure to write a reveiw for it!

Product Research

Enclosure Compatibility


Dual Voice Coils: For increased system flexibility, the woofer has two 4 ohm voice coils. When the voice coils are wired in parallel with each other, the woofer presents a 2 ohm mono load. When the voice coils are wired in series with each other, the woofer presents an 8 ohm mono load. In addition, each coil may be connected to a different amplifier channel and each channel will see a 4 ohm load.

Curvilinear Aluminum Cone: The curvilinear aluminum cone is lightweight and extremely rigid for low distortion and superior bass response.

High-roll Butyl Surround: The high-roll butyl surround damps cone resonance and ensures longevity.

Cast-Aluminum Basket: The non-resonant cast aluminum basket ensures perfect alignment of the speaker's moving parts.

Flat Uniform-roll Spider: The spider design provides maximum control over cone motion at the limits of the speaker's excursion, and reduces even-order harmonic distortion compared to cupped spiders.

Vented Pole Piece: A flared, polished and vented pole piece is used to provide optimum cooling of the voice coil and minimize turbulence.

1.5" 4-layer Voice Coil and Stacked Magnets: The 1.5" 4-layer voice coil and stacked magnets provide high motor force and room for ultra-long excursion.

Gold-plated 5-way Binding Posts: The gold-plated 5-way binding posts will accept pin connectors, spade connectors, banana plugs, dual banana plugs, and bare wire.

Enclosure Compatibility

Recommended Sealed Box Volume: Infinity recommends a sealed enclosure with an internal volume of 0.6 cu/ft.

Recommended Ported Box Volume: Infinity recommends a ported enclosure with an internal volume of 1.0 cu/ft. One 3" diameter x 10.4" long port should be used with a 1.0 cu/ft enclosure.

Recommended Sealed Bandpass Box Volume: Infinity recommends a bandpass enclosure with an internal volume of 0.95 cu/ft. The 0.95 cu/ft enclosure should have a sealed chamber volume of 0.6 cu/ft and a ported chamber volume of 0.35 cu/ft. One 3" diameter x 10.04" long port should be used in the ported chamber.

Free-air Mounting: In addition to being compatible with sealed, ported and bandpass enclosures, the woofer can be used in free-air applications. A free-air subwoofer is designed to be mounted on a baffle board, which separates two areas of the vehicle. For instance, you could mount this woofer to a board attached to the rear deck or placed in the trunk against the rear seat. The trunk acts as the enclosure housing the subwoofer.


Power Handling: The woofer has two 4 ohm voice coils, and each coil can handle up to 175 watts RMS (700 watts peak).
