New beGrimmings in subwoofage – Hello SB1 [€11'200/pr], Grimm Audio's most current thinking on a motion-feedback 20Hz compact subwoofer with 30dB less distortion. Sized to go between the legs of their active LS1/LS1be monitors, the new model also has a bypass switch to work with off-brand speaker systems that use an active filter. The modified woofer is powered by 700 watts of internal class D. "The AD / DSP / DA is real time and fast enough for the whole feedback loop to be effective up to 500Hz. The latency is accordingly small hence negligible. No physical offset is required as long as these subs are placed at equal distance to the listener compared to the speakers."
