Gladen ATM replaces speaker terminal to create a powered subwoofer enclosure

CAMARILLO, CALIF., April 12, 2021 (MEDIAWIRE) – Orca Design and Manufacturing announced it is shipping the Gladen ATM, a single-channel power amplifier that is designed to fit within a subwoofer enclosure. The ATM (Active Terminal Module) replaces the enclosure’s standard 78mm circular speaker terminal with a 200-watt mono amplifier, measuring just under five inches deep and available in two- or four-ohm versions. This innovative design allows retailers to internally amplify any pre-built or custom sub enclosure and offer a versatile, active low-end solution.

The control surface of the Gladen ATM features a high-quality Molex® connector for power, ground and audio inputs, alongside a button that selects between low- and speaker-level input. The ATM automatically detects signal input to turn it on and off. The built-in, low-pass filter lets the installer match the output of the ATM to the subwoofer and enclosure with variable volume and crossover adjustment between 50 and 120Hz. An optional subwoofer volume control (Model RTC-2; sold separately) can be plugged into the ATM and mounted within the driver’s reach.

“In light of the drastic product shortages, retailers are struggling to build personalized audio experiences for their customers,” said Nalaka Adikari, sales director for Orca. “Bass is usually the first audio enhancement customers look for, and the ATM lets retailers bring life and vibrancy to factory audio playback by adding low end with a single component that can be removed when storage space is needed.”
