The SUBLIME is an ultra compact passive 6.5″ dual coil subwoofer that offers the ultimate blend of a compact size and deep, fat basses. Thanks to the built-in X-over, this subwoofer is the ideal partner for the MASK2 top speakers.This thinnest subwoofer on the market (only 12 cm deep) allows for easy integration into any interior: on the wall (mounted with the included wall mounting brackets), behind curtains or even under furniture. Speaker and connection terminals are invisible when mounted on the wall using the included mounting brackets. It may look like a small heating radiator, but instead of heat, it will radiate musical vibes in your room.The SUBLIME subwoofer has a built-in stereo X-over filter, thus eliminating the need for external filters. The X-over filter separates the high frequencies and sends them directly to the top speakers. Optionally, you can use the SUBLIME speaker in an active speaker setup, using an active filter and separate power amplifier. You can use the SUBLIME up to 200 Hz.
