Klipsch Said No in Subwoofers Posted February 6 3 hours ago, MMurg said: You may need to use a device like a MiniDSP if you want to manually set correct distances and levels for the subs independently. Things then get a bit more complicated to do correctly. +1 on using a MiniDSP 2x4HD (or similar DSP) when dealing with multiple subs. The subs can be dialled in using measurements from REW and analysis from MSO (Multi-Sub Optimizer). The resulting configuration (delays, gain, PEQs) can be exported from REW right into the MiniDSP 2x4HD. Both REW and MSO are superb pieces of shareware/freeware.
