I have an old pair of IPL M3TL transmission line speakers that I built myself. They have a Morel MW144 woofer and a Morel MDT32 (or similar) tweeter.
I have 2 Marchand XM9 crossovers (2 way) that are fed from a Rotel RC970BX control amplifier. The crossovers feed into 2 x Rotel RB970BX power amplifiers.
I cant remember what the crossover frequency is set too but it can be easily changed using a plug in resistor board. I think there is an option for damping controls on the crossovers.
I am wondering if it is worth trying to get this set up working properly again? I have NOT done any measurement on this and would not know where to start. I don't even know if active crossovers are suited to these speakers. I still have the passive filters that they came with somewhere.
The amps are in boxes at the moment so maybe it's time to have another listen? What are your thoughts on how I can make the most from the speakers I'm using? Thanks.
P.S This active setup does sound different to the passive setup but I'm not sure if I'm getting the best I can from it. Also, the speakers are very boomy in a small room

The chance that your active xo will work for your drivers/enclosure is pretty low.
Even if you tweak the xo frequency.
But if you have 4 channels of amplification you can certainly try to bi-amp them.
