NEW FOR '82

Powerful Mach One Liquid Cooled — For Bass You Can Feel!

Genuine Oiled Walnut Veneer.  Massive 15" Woofer With 32-Ounce Magnet.

Realistic Mach One "Liquid Cooled." The new Mach One Liquid Cooled features "ferrofluid-cooling." Ferrofluid is a magnetic liquid that increases a speaker's power handling capacity and helps control voice coil travel for improved linearity of response. And if it's tight "wall-shaking" bass you like, this speaker is for you! Its 15" woofer, sectoral midrange horn and heavy-duty horn tweeter work in concert to deliver all the punch that today's music packs. Plus, the frequency response covers the entire audio range so you won't miss a note of your favorite performers. All this plus a beautiful finish — because we know you want wood, not plastic or vinyl.

SPECIFICATIONS:  Response: 25-20,000 Hz.System Sensitivity: 90 dB (SPL at 1 meter/1 watt). Power Handling Capacity: 160 watts.Impedance: 8 ohms.

Component Features:  Liquid cooled sectoral midrange horn designed to provide a true spatial image — smooth 800-8000 Hz response for "live" presence.  Liquid cooled heavy-duty "bullet" tweeter horn delivers crisp, clean highs from 8000-20,000 Hz.  Treble and midrange L-pads for precise adjustment of response to suit room acoustics.  Acoustic suspension woofer pumps out huge volumes of air — you can feel the bass down to 25 Hz — four-layer voice coil is edge-wound on a brass form to increase the magnetic flux density for improved performance.
