Infinity Unveils Variable Frequency Woofer
February 27, 2003 -- Woodbridge, N.Y. - Infinity new Kappa Perfect VQ subwoofers, which offers a variable Q design, providing numerous options to installers. The Kappa Perfect VQ subs allow consumers to use a baffle of infinite size or no box at all. The patent-pending, vriable Q design enables users to vary the frequency of the woofer, or Q, to achieve optimal performance in a particular enclosure or adjust the box required to obtain a certain sound.
Kappa Perfect VQ series subwoofers offer a unique approach to adjusting the Q. They enable the motor strength to be varied using metal vent polepiece inserts, which provides additional cooling of the motor structure. This increase in thermal capabilities provides more power handling.
Q adjustments enable the woofer to be optimized for a particular enclosure or application and may provide the user with a superior listening experience for several applications in a single enclosure. In addition, VQ allows a single woofer to work in many different type and size boxes.
"The Kappa Perfect VQ subs are the only woofers a consumer needs to purchase," says Andy Wehmeyer, product marketing manager, Infinity Mobile Systems. "Because of the patented Variable Q design, these subs can grow with consumers and their systems and be changed accordingly, making them a wise long-term investment."
The subs have a 3-inch-diameter voice coil for upgraded power handling and feature Infinity's new Magnesium Metal Matrix Diaphragm (M3D(tm)) woofer cone material. This material is 20 times deader than aluminum, delivering superior stiffness and damping compared to traditional cone materials.
The butylene-rubber one-piece surround and gasket, provides an optimum blend of elasticity and internal damping. The large size of the roll was optimized to offer good long-throw linearity with the proper amount of control and stability at excursion limits. In addition to a new basket design, the subs feature spider-integrated tinsel leads to ensure long life and noise-free operation at high excursion. This greatly enhances reliability and eliminates audible tinsel lead slap.
The Kappa Perfect VQ line includes 10- and 12-inch single- and dual-voice coil models. The Perfect10 VQ is a 10-inch single voice coil sub, which retails for $374.95. The Perfect10d VQ is a 10-inch dual voice coil sub, which retails for $394.95. The Perfect12 VQ is a 12-inch single voice coil sub, which retails for $424.95, and the Perfect12d VQ is a 12-inch dual voice coil sub, which retails for $444.95.
The Kappa Perfect VQ subs will ship in the first quarter of 2003. For more information, call (800) 553-3332 or check out the company Website at www.infinitysystems.com.
What do you guys think of this. Do you think this is just a gimmick or a new step in sub woofer technology. What good would this "technology" have in the car audio industry? It sounds cool but how would it benefit the average consumer.

Their theory looks OK, I just don't know how much the total Q of the driver can change based on that single component... If their charts are correct, then the difference would be drastic.
Well, you guys always know my vote, someone send me one and I'll check it out!

I think Infinity should try improving the build quality of the Perfect rather than coming up with a Variable Q design ...
It may be new and innovative, but I'd rather have a Perfect that isn't fragile ...
