THP-CXB Owner’s Manual

Congratulations on your purchase of the 

 

   CXB Subwoofer Power Amplifier.

Coupled with any of the Soundolier Passive Subwoofer Speaker Systems, it will give your audio/video
system excellent low frequency output.

Bass frequencies are critical to realistic sound reproductions. After you’ve hooked up the THP-CXB

with a subwoofer speaker system, you will discover just how much “punch” and depth you’ve been miss-
ing. No matter what kind of music you listen to... whether you listen to it loud or soft... you’ll experience
sound that’s richer and fuller. Bass guitar and string bass will have more impact. You’ll be able to FEEL
as well as hear percussion just the way you would at a live performance. If you have a “Home Theater

System” movies will come alive with thunderous sound effects that were never possible without the

THP-CXB Subwoofer Power Amplifier coupled with any Soundolier Passive Subwoofer Speaker.

The THP-CXB is a dedicated subwoofer amplifier with active crossover. It frees your receiver or power
amplifier from the power demands of high-performance subwoofers such as the Soundolier 

   

Freestanding Subwoofer the Soundolier 

   2 In-Floor Subwoofer, and the 

 System. To do

this, the 

 incorporates a built-in crossover system that can automatically “assign” higher fre-

quencies to the main speakers and lower frequencies to the subwoofer.

The THP-CXB has been designed and tested to insure high performance, durability and longevity. The

THP-CXB can be used with any 

 or 

 subwoofer that requires a separate power amplifier.

This manual is designed to take you step-by-step through the hook-up and operating process. The pro-

cedure is not difficult, but IS slightly different than connecting line level components such as a CD play
er or cassette deck. Reading this manual carefully will insure maximum performance from your 

 and subwoofer speaker.
