Dual mono with REL Subwoofer

[audio_engr]

Though I don't use REL subs with my Devialets, I am sharing my past experiences with REL. Nearly 2 decades back, I bought my REL subs Model : STUDIO directly from their welsh factory in the UK sold to me by Richard English Lord aka REL. Mr Lord always recommended using 2 subs as against 1 for better & even distribution of the Low Frequencies and to avoid typical room loading. He also strongly recommended to using their "high level" input as it helps the subs to blend better with the main speakers as it gets it flavour from your main amplifiers. Using ABC tuning-in system, one can get very satisfying results from the RELs. Hope this info helps ...
