Hi Lew
Work continues on my Beveridges and I have ordered a crossover and subs from RM. The DD are in sight for the New Year.
I am not sure how how he would vary the polarizing voltage required in his amps for various speakers- this would be another question for him.
I am interested in DD'ing the Quads ( 57 & 63s) to compare to the Beveridges.
From his website :
"Hi,
I am bumping this topic to go along with the discussion on direct drive for all ESLs, including mine. In the process of making a pair for my speakers I have found how to adapt them to the QUAD 57, 63 and all that have followed. They also will drive the largest 8 panel Acoustats, all Beveridge systems, Sounds Labs and a host of others "
Looks like he claims it can be done..........
