Hey All,


As suggested in another thread, i am coming to you to assist with how my speakers should be setup.


Receiver: Onkyo TX-SR707

Fronts: Definitive Technology BP2006TL

Center: Definitive Technology C/L/R2300

Surrounds: Definitive Technology BP2X

Rears: Polk Audio RC65i

Subs: none at the moment besides the 8" that are integrated with the fronts.


another member suggested that I run a digital coax cable from each of the sub preouts on the receiver to each BP2006 LFE input so the receiver recognizes the subs. After running Audyssey, you'll want to set all speakers to SMALL and raise their crossovers to 80hz.


I've also read to set the fronts and center to Large and the rest to small.


someone please set me straight!

quick spec for the Onkyo TX-SR707:

Quote:

I also have a set of in-wall polk audio RCi (not sure the the exact model. they came with my house) speakers for the rears.

Below are the specs for the RC65i which is what i believe are installed:

The advantage of setting your speakers to small and using the LFE for the integrated subs is to leave that extra headroom for your higher frequencies. Low frequenciy sounds tend to each up power, so using the LFE and the built in amp on the tower for the sub allow that extra power for your higher frequencies which will make them sound better. This is how I would do it, but by all means hook it up both ways and see which setup you think sounds best.

I think the Def Tech BP2006 towers would only be "large" if the built in subwoofer was feed by the speaker level output for the L & R channels. If you wire the subwoofer separately for the LFE channel, then I would set them to small.


Experiment with the crossover for the L - C - R, 60Hz or maybe lower, side surrounds at 60 Hz, and rears at 80 Hz. But don't be afraid to experiment and listen to what sounds best.
