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 12" competition grade subwoofer delivers an amazing 3,000w max. (1,000 watt RMS) of power. Constructed with heavy-duty dual 2 ohm voice coils, it has been 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.
The amplifier recommended to power the TL-1121 is the TL-1023 - 1,000w RMS into 1 ohm.
Features:
-
Ultra strong, rigid hybrid Kevlar fibre cone.
Comprehends the seriousness of competition rigors and the strict demand of audiophile quality reproduction.
-
Progressive high linearity spider.
Provides excellent suspension during extreme SPL.
-
Competition grade 4-layer Kapton voice coils.
Provide extra high power handling.
-
Gigantic magnet assembly.

-

For high reliability and efficient power transfer during extreme conditions.
-
24K Gold plated non-rust high conductance all-metal hexagonal lock tight binding post input terminals.
Ensures a good clean input connection from the amplifier.
