About the Infinity Kappa Perfect10 VQ
Infinity understands that the difference between good bass and great bass is in the details. Incorporating the latest low-frequency innovations, the Kappa Perfect10 VQ 10" subwoofer delivers unbeatable performance and system-tuning flexibility.
Resonance is a big time enemy of great bass, and Infinity's revolutionary Magnesium Metal Matrix (M3D) is the ultimate cone material — it's 20 times less resonant than aluminum! Housed in its die-cast frame, the M3D cone is an ultra-stiff piston that translates the low-frequency signal from your amplifier with frightening accuracy. The butylene rubber one-piece surround/gasket exerts tight control over cone excursion so you'll hear smooth bass even when you're really cranking it!
The Kappa Perfect VQ subwoofer offers the unique Variable Q feature, which allows you to optimize the speaker for use with a variety of enclosures — sealed, ported, or bandpass (even free-air applications). The sub is shipped with two metal polepiece inserts, which can be plugged into the motor assembly to vary the stiffness of the suspension:
- large insert: small sealed or ported boxes, SPL competition
- small insert: medium size sealed or ported boxes
- no insert: very large enclosures or free-air use
This patent pending approach also allows you to change the character of your bass for different applications. Imagine — you could tune your subs for sound quality during the week, then retune for an SPL competition on the weekend! Leave it to Infinity to take bass to a whole new place.

Featured review
I installed this sub in a small box in the trunk of my Lexus SC400. You would think it was in the back set. I have about 300 watts RMS running through it and it handels that with know problem. if Your amp offers an 18dB bass boost push it; you will have a massage parlor on wheels.

Specifications
Magnesium Metal Matrix (M3D) Woofer Cone: Magnesium Metal Matrix (M3D) is 20 times less resonant than aluminum, delivering superior stiffness and damping.
Nitrile-butylene-rubber One-piece Surround and Gasket: This material provides an optimum blend of elasticity and internal damping. The large roll offers good long-throw linearity with the proper amount of control and stability at excursion limits.
Proprietary Die-cast Frame: The frame offers ample rigidity to support the motor structure, and its vented architecture provides greater movement of air behind the cone and spider for maximum cooling.
Spider-integrated Tinsel Leads: The spider-integrated tinsel leads enhance reliability and eliminate audible tinsel lead slap.
Variable Q: The Kappa Perfect VQ subwoofer offers the unique Variable Q feature, which allows you to optimize the speaker for use with a variety of enclosures - sealed, ported, or bandpass (even free-air applications). The sub is shipped with two metal polepiece inserts, which can be plugged into the motor assembly to vary the stiffness of the suspension:
- Large "LoQ" Insert: small sealed or ported boxes, SPL competition
- Small "MidQ" Insert: medium size sealed or ported boxes
- No Insert: very large enclosures or free-air use
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.
Recommended Sealed Box Volume: The sealed box sizes recommended by Infinity range from 0.3 cu/ft to 1.0 cu/ft.
Recommended Ported Box Volume: The ported box sizes recommended by Infinity range from 1.25 cu/ft to 2.5 cu/ft. One 3" diameter x 11.5" long port should be used with the 1.25 cu/ft enclosure and one 3" diameter x 11" long port should be used with the 2.5 cu/ft enclosure.
Recommended Sealed Bandpass Box Volume: The bandpass box sizes recommended by Infinity range from 0.95 cu/ft to 1.35 cu/ft. The 0.95 cu/ft enclosure has a sealed chamber volume of 0.6 cu/ft and a vented chamber volume of 0.35 cu/ft. The 1.35 cu/ft enclosure has a sealed chamber volume of 0.6 cu/ft and a vented chamber volume of 0.75 cu/ft. One 3" diameter x 10" long port should be used with the 0.95 cu/ft enclosure and one 4" diameter x 11.5" long port should be used with the 1.35 cu/ft enclosure.
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.
Note: When used as a free-air subwoofer, no metal polepiece insert is required.
Thiele/Small Parameters: The following Thiele/Small parameters change depending on which metal polepiece insert is used:
- BL:
- Large "LoQ" Insert: 15.05 Tesla meters
- Small "MidQ" Insert: 13.05 Tesla meters
- No Insert: 10.49 Tesla meters
- Qes:
- Large "LoQ" Insert: 0.33
- Small "MidQ" Insert: 0.44
- No Insert: 0.68
- Qts:
- Large "LoQ" Insert: 0.32
- Small "MidQ" Insert: 0.42
- No Insert: 0.63
