BASH Amplifier
This subwoofer features the highly efficient BASH® amplifier technology, which combines the musical quality of class A/B amplifiers with the efficiency of class D amplifiers. BASH® technology translates into more efficient, yet more powerful amplification without the heat associated with conventional amplifiers.

This subwoofer also feature a convenient on/auto/off switch and built-in limiter, which means that sound reproduction will always be clean and as well defined as intended.

SUB 250 driver
At the heart of this powerful subwoofer is a long-throw super driver, capable of moving large amounts of air with incredible speed and precise control. The 8in driver feature Ø 38mm/1.5in four-layer voice coil. The heavy magnet systems feature a vented pole piece in order to avoid over/under pressure behind the dust cap (mechanical damping) when the cone is moving. This unit is an important part of the reason why the subwoofer offer top specifications and peak performance.

Slotted Port Cabinet
This slotted port is a unique integral part of the construction method used for these subs. It´s designed to brace the sides, making the overall enclosure extremely rigid. It also allows for a lower tuning frequency together with a larger port area, compared to a conventional round type, giving both high efficiency and low distortion.

Speaker Level In
This subwoofer features speaker-level inputs, which is vital if your amplifier/receiver lacks a subwoofer line output.

The subwoofers also have both left and right line-level inputs (for stereo sources) plus a "loop-through" capability to allow the signal to be routed through to a second subwoofer.

Level-, Phase- and Cut-off controls
Continuously variable level, phase and cut-off frequency controls make it easy to tune the subwoofer to suit virtually any speaker on the market as well as different placements and personal preferences.
