Introduction
Congratulations on your purchase of the Competition Pro TL-1121 subwoofer.
After huge amounts of careful and detailed research, design, development and testing,
TheLoudest.com proudly present this stunning subwoofer packed with revolutionary features
using state of the art components and materials.
The Competition Pro TL-1121 is a 12" competition grade heavy-duty subwoofer designed to
pound out deep, ultra low sub-bass which is nothing short of accurate in definition. The TL-
1121 subwoofer has a durable, precision-engineered, robust build that offers fantastic bass
reproduction, and maintains such clear bass reproduction at uncompromisingly high power
levels.
For every day-listening, installing the TL-1121 in a sealed enclosure (such as TL-1120) will
result in high fidelity reproduction over the entire bass frequency range, suited to most
types of music, giving audiophile quality sound.
For extreme listening or SPL competitions, installing the TL-1121 in a ported enclosure (or
simply removing the plug on the TL-1120 enclosure) unlocks the full potential of the woofer,
resulting in pure subsonic power of monstrous proportions, ensuring the TL-1121 hits the
hardest, deepest and loudest bass, blowing away just about anything that dares to stand in
its path.
It is imperative that you read through this manual before installing and operating the
subwoofer. This will ensure correct configuration and operation. While this manual details
generally how to install the subwoofer, if you do not have sufficient experience or tools, it is
best to have it professionally installed.
This subwoofer functions best in a system with a good quality source unit. Connecting it up
to a system which includes a poor quality source unit (such as a standard, factory fitted one)
may not give good results.
The input power handling of the TL-1121 is 3,000 watts max. (1,000w RMS). The amplifier
used to power the TL-1121 (the TL-1023 is recommended) can draw very large currents
from the vehicle battery and alternator. Depending on vehicle model, one or more of these
components may have to be replaced to enable the amplifier to operate to its full potential.
For further details regarding this, please refer to the amplifier manual.
TheLoudest.com accepts no liability for any damage resulting to vehicle components when
installing or operating the TL-1121 subwoofer. It is the sole responsibility of the user to
follow these instructions carefully and upgrade any vehicle components as required.
Again, if you do not have sufficient experience or tools, it is best to have the unit
professionally installed.
Keep this manual in a safe place so it is accessible for future reference.
