All you need are,8-10" subs, a pair is ideal. Drive them from your main amp using the high level inputs, so not run cables from your preamp, set the crossover at 40Hz, adjusting the volume to blend, use a piano and a vocal recordings, when either becomes to thick/heavy sounding you raised the volume to high, after you are happy try 50Hz, you may have to adjust the volume a bit, choice is yours on what you prefer, don't crossover higher than 50Hz.
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.
