Thanks Zen Mod, understood. Seems like Iíll have to make time for the removal of the crossover plate if Iíd like to try out the bi-amp project. Iíll look at the schematics and then see if thereís a place to disconnect and create a jumper to re attach it.

As always Zen Mod, your help and advice is greatly appreciated. From looking at the schematic it appears (to me) that if I detached/clipped/created a jumper on the lead going from coil L1 to the positive input of the crossover board that it would isolate the woofer crossover components. Am I correct? If memory serves it should be very easy because the coils have long leads on them.

You might prefer the AJ on bass as it has a higher gain than the M2 (don't know the M2X). If you have a large room higher gain on the low end will help otherwise it will sound anemic on bass and the high end too loud. If you are able to tune it with an external active crossover then you can experiment both ways. Try with the existing crossover first before deciding to spend on actives.

According to FIRST WATT PRODUCTS there is a 5dB diff in gain between
the M2 and the AJ, so you likely will need to have some facility to adjust the
line level going into the two amps.

Thanks everyone for your input and suggestions! Looks like I have some more research to do before I go ahead. From what Iíve been reading an active crossover using something like a mini dsp would fit the bill and even allow for independent gain settings and outputs to the two amplifiers.
