SYSTEM CONFIGURATION #2
– 10 –
The largest improvement in sound quality always comes when adding some kind of subwoofer via a dedicated subwoofer
amplifier and electronics crossover. The electronic crossover ensures minimal overlap of the bass response with the mid
and high frequencies from the other speakers resulting in a more accurate performance compared to conventional coaxials
with additional power.
By installing this amplifier in the stereo mode, you are able to drive two subwoofer speakers and in to low impedance loads
(e.g., 2 ohms) without over heating the amplifiers. Also, such an installation more easily supports a standard 2 speaker
woofer box that may already be constructed. Since two woofers can play 6 decibels louder than one at a given power (due
to acoustical laws of “mutual-coupling”), the resulting sound pressure level is substantial. This is probably the most
common use for a conventional two channel amplifier there is.
