Hello..
I got a 5234 acrtive crossover with 2 x 250hz division..
The internal crossover of 4343b (3143) cuts the bass at 300 Hz.. so the 5234 will separate only a 'third' kower. Do you think this is of importance for the performance of the bass-midrange 2120 ?
The advantage is saving one big capacitor for the whole MHT-Unit and the inductor for the bass speaker in signal-flow..
