Running two (chained) SVS SB-2000 from left side (mono, of course) and one SB-3000 off the right channel. (Would like a 4th. Thanks, Erik; I've been reading your sub stuff lately and enjoy it.)
The DSPeaker Anti-Mode 2.0 had L&R analog outputs and balanced which I cannot use. Of course both are signals after DSP processing, room correction, (and/or a high pass to the D2s).
I tried a basic block Y outside the integrated's pre-out, and also right at the DSP's 'analog input' but got no sub signal, not a vibration. Perhaps putting the subs in the 'active' or powered analog output after the DSP provides enough signal to activate the sub's circuitry, not sure one bit. Guesses.
D2's have limited headroom downstairs and would love to relieve some of the burden trying to high pass. Hmm... Thx.
