Rotel + Sub

[BWLover]

Hello everyone! I'd like some advice on how to hook up a B&W subwoofer with a stereo pre-amp, as I have only ever done this with receivers (dedicated sub out line). I would like to use the crossover on the sub to send anything above 80hz to my B&W 683S1's. What are my options for doing this with a Rotel RC-1082? I would rather not use the speaker terminals on the sub because that would mean purchasing another set of speaker cables. For those not familiar with the Rotel, here is a back drawing.

Hi, BWLover.

need to know which sub you have or plan on using.

I have an RC-1082 preamp that I use in combination with a B&W ASW750 sub. I use the high-pass filter on the sub to send everything above 80Hz to my 803D speakers. I do this because the RC-1082 does not provide an equivalent filter. Note that I have also set the low-pass filter on the sub to 80Hz so that it only plays 80Hz and below.
