Dingman Posted November 21, 2011 Share Posted November 21, 2011 I'm a bit confused. My AVR has a sub out but doesn't have a crossover Value. How should I configure the RW_12D? I'm using KLF 20' s in this 2.1 configuration. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted November 21, 2011 Share Posted November 21, 2011 That's odd. I'll assume that it has a set value that's non adjustable? If so, turn the low pass filter on the sub amp to it's highest setting. Quote Link to comment Share on other sites More sharing options...
StephenM Posted November 21, 2011 Share Posted November 21, 2011 What receiver? Many 2 channel receivers do not include a subwoofer crossover. Quote Link to comment Share on other sites More sharing options...
Dingman Posted November 21, 2011 Author Share Posted November 21, 2011 Rats, typed long reply and then lost it. At any rate, the AVR is the Marantz SR-4023. http://us.marantz.com/us/Products/Pages/ProductDetails.aspx?CatId=HiFiComponents&SubCatId=0&ProductId=SR4023 EDIT: LOL, found this in the description of the unit on the website... "A separate low-pass preamp output lets you add the powered subwoofer of your choice as well. " You'd think I could find where the low-pass is set at, eh?

StephenM Posted November 21, 2011 Share Posted November 21, 2011 No mention of a low pass filter when I did a search of the owners manual. You could e-mail Marantz I suppose. However, since the KLF-20s aren't high passed, IMO your best option is to set your subwoofer's crossover to the KLF-20's -3dB point (34Hz). You would also want to play with the phase to make sure that your mains and subwoofer are working together. Quote Link to comment Share on other sites More sharing options...
mustang guy Posted November 21, 2011 Share Posted November 21, 2011 This is a case of simply letting the stereo speakers have full bandwidth and augmenting the sound with a subwoofer, as your mains must not have the low frequency extension to get low enough to your liking. The answer is, just set the knobs on the subwoofer to suit your taste. I usually start around 70 Hz or so, and work my way down. Adjust the gain on the sub and you are done. If you ind it not to your liking, just adjust the knobs till you get it right. Anybody who has a regular stereo receiver and uses a sub has to do this. Yours has a line out, which means you will get cleaner bass than speaker level outs. Quote Link to comment Share on other sites More sharing options...
