I have no other speakers apart from these two speakers to connect to the receiver. From what I read, should I bi-wire the high and the mid to one channel and just do a RCA cable connection for the subs and not connect anything for the low's? (keep setting small/large??) or should I do separate connection for all high, mid and low to all separate channels? (settiing small/large) please help.
If the speakers are missing the bridge connection plates, just ask Definitive Technology support to send you some. They just sent me eight free of charge to replace ones I had lost.
In the meantime, you don't need to bi-wire them, just connect the AVR's output terminals with good 12 gauge speaker wire to either the mids or highs and jumper the other with short wires. Once you get your bridge plates from DT, you can replace the short jumper wires with the plates.
Don't connect the low speaker terminals (i.e. don't bridge them with a bridge plate or jumper wires). If you do, all you are doing is taking the signal (and thus the distortion) created by your AVR's amp and reducing it back to preamp levels and then reamplifying it getting a second round of distortion. Use the preamp input instead and connect each L/R speaker to their respective front channel's preamp outputs from the AVR (don't use the LFE output, only send that to your sub). The AVR can drive both the speaker level outputs into the mids/highs and also the preamp output into the BP2002's amp simultaneously. You may need to toggle the sensitivity switch and play with the subwoofer level and EQ knobs to get the bass to balance (it depends on the voltage of your AVR's preamp outputs). I have my switch set to high sensitivity, and both dials set to vertical (i.e. no gain and no boost) and that works best for me, but I use a Yamaha RX-A3070 AVR which might have different preamp output voltages than your Onkyo.
If you have great subs, then try the mains with a crossover (start at 80Hz and then work downwards to see what sounds best). I use 80Hz.
If you don't have a sub, or it isn't that great, try running the mains as full range. I did that for a long time when I had no subs (and also when I had bad subs). Once I got good ones, I crossed over my mains at 80Hz because the 15" driver and 300 watts RMS amp just could not keep up with the subs without distorting.
Also, after you are done and have everything sounding the way you like, post back what worked best for you and let us know.
