Upgrade for old Dahlquist DQ LP1 Crossover


I have been using this old Dahlquist DQ Lp1 crossover to send the LFE to my passive VMPS Larger sub. To me it sounds ok but I have not had anything to compare it with. There must be an upgrade to this unit seeing that it was made in the early 1980's.

At one time, Frank Van Alstine modified these units. Cost unknown. You can reach him at 952-890-3517.
It was a Van Alstine modified DQ LP1 that Harry Pearson used in his writings about one of his then listening room system which consisted of Quad ESL63's with Maggy Timpani panels for the low end
