Know before you buy
The Abyss 8 uses one active 8-inch aluminum woofer paired with two passive radiators. This configuration allows the subwoofer to move more air and produce deeper, more impactful bass than a standard sealed design of the same size.
Yes, the Abyss 8 features built-in wireless connectivity, allowing you to place the subwoofer anywhere in your room without needing a long cable run from your receiver.
ARC measures the acoustic properties of your room and automatically adjusts the subwoofer’s output to compensate for unwanted reflections and standing waves. This ensures the bass sounds tight and accurate rather than boomy or muddy.
Absolutely. With its precision DSP engine and 500W RMS power, it provides the speed and detail required for music, while maintaining the dynamic impact needed for cinematic sound effects.
You can manage settings like volume, phase, and crossover frequencies directly through the MartinLogan control app. This allows you to fine-tune your audio from your listening position without needing to reach behind the unit.
Yes, the robust, thick MDF cabinet is designed to minimize resonance and vibration. By keeping the enclosure rigid, it ensures that the energy from the woofer is directed into the room as sound rather than being lost to cabinet rattle.
