High Performance Powered Subwoofers
Congratulations on your purchase of an Atlantic Technology powered
subwoofer. A well designed subwoofer, properly integrated into your sys
tem, will enhance your listening pleasure dramatically by providing the
bass foundation upon which most music and special effects are built.
These subwoofers are capable of delivering very high output levels and
wide dynamic range. When properly placed, these subs will provide
smooth in-room bass response down to approximately 25Hz, with a peak
SPL of over 102dB in a normal sized room.
Their high-current amplifiers, coupled with their rugged long-throw
woofers in sealed enclosures, generates accurate deep bass with a mini
mum of distortion.
Your Atlantic Technology powered subwoofer will smoothly integrate
with virtually all brands of loudspeakers on the market. From the rocksolid amplifier to the easily accessible controls, this is one of the most
versatile high performance subwoofers you can buy.
