Yes, that will work, but I might suggest you consider a miniDSP to drive both independently. The reason is that placing them separately may require different EQ curves.
2 sub hook up
I just want to confirm something about adding another sub to my system. Currently running a single SVS SB 4000 sub in my 2 channel system, using its Balanced port. The sub offers Both Balanced inputs and outputs. In hooking up another SB 4000, Current hook up, Benchmark LA-4 mono output (balanced) to subs Balanced right side input. To hook up second sub, would I then use another balanced cable from Ist subs right side (output) to 2nd subs right side balanced input? Thanks , Robert Tks to all as usual!!!
