Lewm, sorry I missed your last post. 1:250 is a huge transformer. The 1:100 Sowter transformer is very large and is +- 3 dB 50 Hz to 18 kHz.
I cross over to subs at 125 Hz which is quite high. 500 Hz is well into the midrange. 256 Hz is about middle C.
I have not had the chance to open up a Sound Labs interface yet. Can you just wire around the controls to eliminate them from the circuit without modifying the cross over network? I do not like pots in speakers signal path. Bi amping the transformers is an interesting approach. If I do Sound Labs I will try to wire past the controls and use one big amp like an Atma- Sphere MA 2. I will be able to correct any response aberrations with room control.
