ULS-15 MK2 Subwoofer

We have increased the output of the ULS-15 by up to 5 dB, added Qcontrol, MBM mode, and reduced the price!


The ULS-15 MK2 represents our most remarkable performance per dollar improvement to date. We have increased the output capability of it’s predecessor, the ULS-15, by up to 5 dB, added more flexibility (Q control, operating modes), and lowered the price considerably while retaining the same compact size.

We achieved this remarkable feat by platform sharing – our three new models (the VTF-3 MK5 HP, VTF-15H MK2 and the ULS-15 MK2) use as much similar components as possible. The economies of scale of using similar components help cut costs.

The ULS-15 MK2 now has two operating modes. In the regular operating mode, the ULS-15 MK2 has flat response down to 20 Hz in free field (in-room response down to as low as 10 Hz). The second operating mode allows the ULS-15 MK2 to be used as a mid-bass module (MBM), with even higher headroom than our MBM-12 MK2. Unlike the MBM-12 MK2, the ULS-15 MK2 even in MBM mode has strong output capability down to well below 20 Hz.
