Unfortunately (for some of the replies) this is not an experiment in amplifier matching. While horizontal bi-amping may be a fun thing to do, simplifying and minimizing cables, devices and speaker distances is high on the list.
In an ideal world I would find a single stereo amp with built in DSP crossover and EQ capabilities to drive each speaker.
I can find small enough stereo enclosures for the amp modules I already have but I can’t find them with a built in crossover. Hypex and miniDSP and Dayton offer plate amps with all these features and miniDSP’s just happens to fit the back panel.
The alternative, a single stereo amp under each speaker is still do-able but leaves me with an external crossover and 2 XLR cables going to each amplifier.
