Model 642e SB
High Performance C.O.R.E. Technology
THX Select Certified Powered Subwoofer
Congratulations on your purchase of an Atlantic Technology 642e SB
powered subwoofer. A well designed subwoofer, properly integrated
into your system, will enhance your listening pleasure dramatically by
providing the bass foundation upon which most music and special
effects are built.
The 642e SB is capable of delivering very high output levels and wide
dynamic range. When properly placed, it will provide smooth in-room
bass response down to approximately 25Hz, with a peak SPL of over
105dB (2000 cubic foot space).
The proprietary high-efficiency amplifier is conservatively rated at 300
watts RMS. This amplifier, coupled with the massive 12” long-throw
woofer in a sealed enclosure, 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 rock-
solid amplifier to the easily accessible controls, this is one of the most
versatile high performance subwoofers you can buy.
What’s THX?
THX is a series of demanding performance standards and specific tech-
nologies developed by Lucasfilm Ltd. (of Star Wars fame). Equipment
that meets the rigorous THX standards will deliver performance in your
home that matches as closely as possible what the director/artist/engineer
heard and saw during the final mixing of the source material. Please note
that THX is not a separate surround sound decoding format. THX-certi-
fied equipment enhances every viewing and listening experience, regard-
less of the surround format used.
THX Select standards are based upon a room size of 2000 cubic feet (L x
W x H). This does not mean these components must be used in a rooms
this size. The room sizes simply provide a frame of reference, as they indi-
cate that these systems must deliver a minimum level of performance in
this specified room size. Your 642e SB is THX Select certified. For more
