As Good As It Gets. Kevlar fiber can’t stretch, which is why it reduces distortion in a speaker and why we chose it for the W695s’s woofer cone. The W695s’s 6-1/2-inch Kevlar woofer puts out incredible bass down to 32 Hz, which is lower even than some subwoofers can play! A cast magnesium basket provides a super-stiff frame for the powerful woofer. The W695s’s 1-inch aluminum-dome reproduces high frequencies with clarity and power, and it also pivots so you can direct the sound where you need it. Boost switches for bass and treble provide an extra +3 dB kick when it’s needed. With 90 dB sensitivity and 150-watt power handling, the W695s works great with amplifiers of any power rating.
