Grimm Audio LS1s Subwoofer (Stereo Set)

Grimm Audio LS1s Subwoofer (Stereo Set) is a pair of stereo subwoofers that integrate seamlessly with the LS1 or LS2. The phase corrected crossover at 70 Hz is already built into the LS1, so just adding the subs turns the system into a unique phase coherent three-way system. Although the LS1 on its own can play down to 40 Hz with quite impressive power, the bottom octave down to 20 Hz is hard to produce with a two-way loudspeaker system. Classical music benefits from a balanced reproduction of these ultralow frequencies.
