172 PBM
High Performance Powered Subwoofer
Congratulations on your purchase of an Atlantic Technology 172 PBM
powered subwoofer. With proper care, your new subwoofer will
provide many years of trouble-free performance.
The 172 PBM 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 20 Hz, with a peak SPL of 108dB
(1800 cubic foot space).
The built-in proprietary high-current Class G amplifier is conserva-
tively rated at 150 watts RMS. This amplifier, coupled with a massive
12" long-throw woofer in a sealed enclosure, generates musically
accurate deep bass with a minimum of distortion.
Your Atlantic Technology powered subwoofer will smoothly integrate
with virtually all other brands of loudspeakers on the market as all its
internal electronics have been designed to maintain optimum signal integrity. From the premium
quality gold plated connectors to the clearly marked controls, this is one of the most versatile high
performance subwoofers you can buy. An added benefit is its relatively compact size and straight
forward design.
Features
Your Atlantic Technology powered subwoofer has been engineered using the latest technology and
finest components available. It features:
●
A long-throw 12" driver with vented motor structure and 2", high-temperature, 4-layer voice coil
This powerful driver has a very stiff cone that acts as an almost perfect piston throughout its
operating range. Its massive magnetic motor assembly and high temperature component parts
deliver high performance and exceptional reliability. In fact, the 9.5 pound motor assembly is
identical to the one in our top of the line 15 inch subwoofers!
●
A sealed enclosure for low distortion and deep bass output
Sealed enclosure designs are inherently low in distortion and naturally deliver deep, smooth bass
response with a gradual and predictable roll-off below resonance. As with all Atlantic Technology
subwoofers, we have paid inordinate attention to giving you accurate musical bass reproduction
along with terrific special effects.
●
A linear power high current Class G amplifier conservatively rated at 150 watts RMS
Atlantic Technology’s advanced Class G amplifiers utilize dual low voltage/high voltage power
supplies for exceptional power delivery from a compact and efficient package. One power supply
operates during all “normal” demand periods. But, when a high demand peak signal appears at
the subwoofer input, the second, high voltage supply switches in to dramatically boost the amp-
lifier’s low distortion output capability. The amplifier delivers very high power levels yet consumes
less steady-state power and produces much less heat than standard comparable amplifier designs.
The 172 PBM’s custom designed amplifier has been precision matched and equalized to its 12”
driver. It exerts accurate and powerful control over the driver for the best performance possible.
