I had a DIY sub with quad 57s with passive x-over but just between you and me the bass quality was better without the sub after removing the metal grills.
Quad ESL 57 with subwoofer
Has anyone tried adding a sub to a pair of Quad ESLs?
If so, did it work out? What sub did you use and how did you connect it? Thanks.
