Considering Spatial X5 and anticipating I may be able to decommission my existing sub. This Velodyne DD-12 sub has full EQ capabilities and was relatively easy to dial in for my listening room. Once done, bass modes and the usual nastiness are incredibly smooth and I'm really pleased. So going away from that is a concern, but potentially worthwhile to simplify things and lower the component count - IF I can accomplish the same thing for each of the built-in subs in the X3/X5 speakers...
So how to accomplish the same thing with the built-in subwoofers in the X3/X5 series? Presumably I could get a MiniDSP and dial things in with a calibrated mic using REW, but I do not want to do this at or just after the source. I would prefer to just be doing this on the bottom frequencies, so after whatever crossover network exists in the Spatial speaker - basically the signal that goes to the subwoofers. Is this possible? I know nothing about the crossover in the speaker, so maybe I'm out to lunch. I guess my question is: is there a low-pass filter on the speaker where I would be able to "insert" EQ for sub only?
