I need to know the woofer/midrange crossover point for the M80Ti's. I am going to attempt to bi-amp with SET amplification (30WPC) for the mids & highs and solid state for the woofers. I have some heathkit tube crossover units and am excited to experiment.

The SET amp sounds excellent with the M80's but it occasionally asks for more power then the 30 WPC they offer.

Thanks in advance.
