I recently purchased a pair of Def Tech BP2006TL's and CLR2300 and now that they have gone through their break-in period I want to calibrate them. Since these speakers contain built-in powered subs is calibrating them any different than "normal" speakers? Some other info that might help: 1) I run them as large on my receiver (Denon AVR-3803)settings. 2) They are connected with speaker wire (Ultralink 12 guage), I dont use the separate LFE input. 3) I have a Radio Shack analog SPL meter and the Video Essentials DVD. I would appreciate any help as I am rather new to HT. I had no problems calibrating my old speakers but didnt know how built-in subs affect this.
