DX4 versus PM4A (Drive Units)

by Arno P, Sunday, September 24, 2017, 18:28 (84 days ago)

I have been playing my DX4's in big backloaded horns for years...great sound but I wondered if I could stretch it further by changing them for PM4a's (Very low QTS 0,164 vs 0.218)

Any thoughts on this?
I am going to low-pass the lowther and have the mids done with a TAD TD2001 Tractrix
