What modifications have you done to the SB-5? I am very interested because have a SB-5 and four Control 5 Plus that I want to use in a home theater system. The Control 5 Plus is connected to a AV receiver and they perform excellent as front+back. Can I use the SB-5 (with a separate amp) as a sub in that system and how does it perform?Moderated By: brian@diysubwoofers.org
