Axton ATB20A - 20 cm / 8" active subwoofer for cars and motorhomes, compact enclosure bass box with amplifier, active bass box with high-level inputs, 140 watts. Compact, powerful, and modernly designed, the Axton ATB20A active subwoofer is developed for music lovers who do not want to compromise on space or bass while on the go. With dimensions of 315 x 275 x 330 mm, the bass box can be flexibly positioned in larger vehicles such as motorhomes or trucks, but also fits in the trunk of smaller vehicles. Quick to install and remove, Axton's bass box is also suitable for leased vehicles where minimal modifications are desired.

The surface coating of the new bass box is a highly durable structural paint, similar to what is used in professional sound reinforcement technology. This protects against unwanted damage, which can easily occur in the trunk, and makes maintenance easier, ensuring the ATB20A always looks good. The newly developed woofer with passive membrane features a one-piece construction with a special membrane geometry for precise bass reproduction, even at high excursions. Combined with lightweight membrane material and a strong drive, this results in a very high efficiency. The integrated amplifier delivers 100 watts RMS and provides punchy, powerful bass. It is securely located at the rear of the enclosure, yet adjustments can be conveniently made at any time.

The compact active bass box has all the necessary adjustment options on board. These include the integrated electronic 12 dB/octave low-pass filter, adjustable between 50 - 150 Hz, as well as a variable phase shift (0 - 180°), input gain, and a bass boost (0 - 12 dB). Axton's enclosure subwoofer features RCA inputs and high-level inputs with an auto turn-on function. This makes the versatile ATB20A perfectly equipped for a simple direct connection to factory radios, multimedia, and other devices.
