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.

Our take on the Infinity Kappa Perfect 10.1

by Guest Writer

The Infinity Kappa Perfect 10.1 10" subwoofer combines a rugged aluminum cone and high-roll butyl-rubber surround to produce slammin' 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 massive 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 Perfect 10.1 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.

Enclosure Compatibility

Features

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.

Excellent! Performed BEYOND 10" Expectations.

Written By Anonymous, Crescent City, FL on Tuesday, March 06, 2007

I have my Infinity Kappa Perfect 10.1 matched with a 800 watts D-class amp. It is wired at 2-ohms and is very clean and loud.

I have two enclosures I have tried the Kappa Perfect 10.1 with:

The first one is a Q-Logic 0.66 cu. ft. sealed wedge box. The sound quality is VERY TIGHT and responsive. When I listen to rock I love how loud and "punchy" the bass is.

The second enclosure I've tried the Kappa Perfect 10.1 in is a custom 1.5 cu. ft. 3" ported box I built. It perfectly matches the manufacture's recommendation for box size for a vented enclosure. When I listen to R&B and songs with more bass, it sounds to me like the bass is 2.5 times louder in the ported box than in the sealed box. However, it does lose some of it's "punchiness" due to the box being ported.

I highly recommend the Infinity Kappa Perfect 10.1 for anyone who wants a sleek, clean, and powerful 10" sub that performs beyond its expectations. It's peak is 1500 watts, and I am shocked with how great mine has functioned at only half of it's potential. I have had mine going on a year now and have had nothing but pleasure and satisfaction from it.

Crutchfield Customer Review (What's this?)

You will not be disapointed with these subs. i made two custom fiberglass boxes to fit in each rear door of my 03 ranger. i am running a kenwood 9152d (900 @ 2ohms) to power both and these things sound excellent. i listen more to rock so i like tight loud bass and these paired with a sealed box=excellent. i have no complaints except like one guy i wish they came with some mounting screws and had a cool grill cover for them. great deal.

Awesome Sub

Written By Andy, Sugar Grove, PA on Sunday, February 11, 2007

Crutchfield Customer Review (What's this?)

I've most recently had cheaper MTX and other subs, that sounded ok at best. I got a new truck and had to do a new system, so I decided to spend a couple more bucks and get some good subs. These Infinity's were well worth every penny. I have two 10.1s run by a Pioneer 780W amp. They are super clear, no distortion, and I'm sure they can handle twice the power they're getting. I bridged the amp to one sub, and it sounded great too. I chose the subs, in part, because they were going under the back seat of my extended cab Silverado, and had to be in very small enclosures. They ended up being smaller in volume than reccomended, but they sound great. Great sub for tight spots.

Infinity Kappa Perfect 10.1

Written By Matthew, Murrieta, CA on Tuesday, February 06, 2007

I have tried an Audiobahn 12" sub with unsatisfactory results.

I finally got rid of them and got these perfect 10's and am very pleased with the results. I have a mid-sized sedan, a sealed enclosure, and 400Watts running to one of these. Bass hits hard when listening to the right music some frequencies do not hit the inside of the car the way I would like them to, but I may be just too picky. These speakers are made to sound clean, NOT loud. Trust me they get loud enough to hurt your ears, but not loud enough for some people looking to disturb the neighbors. Small amount of noise from the speaker actually physically moving when I am very close to the front of the speaker, not sure if this is normal?

I have tried to include as much negative points as I can for this review, and I have had a hard time doing it. This sub still gets 5 stars!

These Subs Are Great

Written By Brandon, Keokuk, IA on Saturday, January 20, 2007

Crutchfield Customer Review (What's this?)

All I can say about these subs is WOW!!! I got them on the buy one get one free deal and these subs absolutely rock. I have them set up in a mtx box with a Profile ap2000 amp and they are so loud that my review mirror will not stay in the same position. Also they are crystal clear for clarity to which was very important to me. In other words you should get these subs.

Great sounding sub just wish it came with mounting screws. By the way this sub will not fit in the MTX Thunderform box for a 2001 f150 without a little modification.

A giant in a small package

Written By Kamran, Reston, VA on Wednesday, January 10, 2007

Crutchfield Customer Review (What's this?)

I got the two-fer deal but I'm only using one. I was using an Infinity Perfect 12VQ that was a bit too big for my trunk because I have the amps and crossovers mounted upside down under the rear deck, so I had to scale down to a 10-inch. The sound is amazing -- I can't even tell the difference! This sub puts out such clean, tight and powerful bass you won't believe it. It's so good one is more than enough. The people that wrote negative reviews on this sub just didn't know what they were doing. SQ or SPL, this one's got you covered. I'm running it off an Alpine MRD-M605 400W nominal and it takes everything I give it. It definitely lives up to its name: PERFECT.

Just Plain Awesome

Written By randomnote1, Lebanon, PA on Friday, January 05, 2007

Crutchfield Customer Review (What's this?)

Ordinarily I would have bought a 12 inch speaker for my car, but I decided that my trunk room was extremely valuable and I couldn't lose it. So after some planning, I decided to go with 2 of these and put them in a custom fiberglass boxes that I am building. I've only got one completed so far, and it pounds!!! I can't believe how good just one 10 inch sub sounds! I can't wait to get the other one in and do the final tuning on my system. It just plain sounds good!

Love this Sub

Written By Lee, Boston, MA on Wednesday, December 27, 2006

I've been using this subwoofer in either the dual voice coil or single voice coil for over 3 years now, and I absolutely love them. I've owned Polk, Rockford and JBL subs before, and these Perfects are perfect. They can handle whatever power you can throw at them. They sound musical- they make everything from Metallica and Testament to Stevie Ray Vaughn or Fiona Apple sound great. And at the same time can pound out the Chemical Brothers or Prodigy until your rear view mirrors fall off. I'm no competition sound expert or anything, but I love listening to music in my car, and I think the Perfect sub IS the perfect sub. Get one- you won't be let down.

impressed

Written By paul, Williamsburg VA on Tuesday, December 26, 2006

Fantastic speaker! I replaced a Kicker Comp. 10" in a type 1 sealed box in my 02 king cab Nissan Frontere. I am driving it with a bridged 150 watt Eclipse amp. I was a litte worried about not having enough power but I was so wrong. This speaker is so very acurate and I actually have to turn it down below flat. I listen to primarily early 70s rock and roll and it is just unreal. I chose this one based on the reviews on here and am glad I did.

DISAPPOINTING

Written By Michael, Grand Rapids, MI on Thursday, December 21, 2006

Crutchfield Customer Review (What's this?)

Replaced my Audiobahn DUB100s with the Perfects. WHAT A MISTAKE!

Put them in a custom dual ported box 1.0 cu each with 300 RMS watts apiece.

The bass was so quiet and soft from the two subs, thought only one was hooked up. NOT a SLP sub for sure.

Expected much more at this price point, not much less. Returned the Perfects and was so glad to have the DUB100s reinstalled.

Unbelievable

Written By John, Concord, NC on Sunday, December 10, 2006

Crutchfield Customer Review (What's this?)

I just picked a set of these puppies up and they are a lot more then I expected. The bass is delivered hard and tight. I have 2 of them in a Qlogic box hooked up to an Audiobahn 12005DN amp controlled by an Alpine CDA-9853 HU. These subs are worth every penny.

My advice...buy these!

A very tight accurate sub.

Written By Len, Phoenix, AZ on Sunday, December 10, 2006

Crutchfield Customer Review (What's this?)

I have been involved in automotive and home audio video sales and installations for over 30 years, including custom, high end home theater systems. I think I was one of the first people to run a single ten inch sub. I listen to all types of music and I like my music accurate, not painful. I used a Polk ten inch db for years powered by a 7th generation, bridged two channel Hifonics amp, (about 350 watts). This Infinity speaker in a Q Logic small sealed enclosure, powered by the small Alpine mono (220 watts) is my best experience yet.

a Perfect Sub

Written By Lance, Schenectady, NY on Saturday, December 02, 2006

Crutchfield Customer Review (What's this?)

I have one Kappa Perfect 10.1 in custom box with a 300W bridged Profile amp, 2 Kappa 6X9s (no amp) and pioneer 7800 HU. With only the 6x9's they thump good, but turn the sub on, and that deep, clean, feel it in your chest bass rumbles my Xterra like crazy.

When ppl hear it, no one believes its just a single 10" sub until i show them. Great purchase, i missed the 2 for 1 deal though.

Best SUBS EVER

Written By Shannon, Bloomsburg, PA on Monday, November 27, 2006

I have bought many subwoofers over the years I have had sony,memphis,and I have heard other subs before but nothing like these infinity Kappa Perfects. They really do mean what they say there perfect, no word about it. If your looking for SQ or just SPL these are the subs you want. trust me, don't buy Audiobahn, or kicker, they were the worst subs I have ever heard before, till I heard these high end infinity's the blew my mind away of there SQ go buy them if you r passion is music like mind you want be sorry. They'll sound great with any type of music.

Infinity Kappa Perfect 10.1

Written By Pete, Wisconsin on Saturday, November 25, 2006

Crutchfield Customer Review (What's this?)

Very nice, crystal clear sound. Plenty loud in my Mercury Sable. Put it in a sealed enclosure in the trunk, removed the 2 factory rear speakers to let the sound through and it is awesome. I was thinking of upgrading the rear speakers, but the sub fills in beautifully. I will probably install a dedicated sub amp later but its running pretty well on the B channel of a Kenwood 8452. Fast shipping as usual from Crutchfield.
