Peter P. Posted January 25, 2019 Share Posted January 25, 2019 Is there a subwoofer that has an adjustable high pass output? I just assumed the adjustable low pass filter on most subwoofers was like a crossover, feeding below frequency "X" to the sub and above frequency "X" through line level outputs and on to the am and the main speakers. Apparently I'm wrong. I don't see any Klipsch subwoofers with line level outputs, to send a high pass filtered signal back to my amp. One subwoofer I'm looking at has both line inputs and outputs but the outputs are fixed at 80Hz. I was hoping to pair a subwoofer with my Heresy's and cross over from the sub to the Heresy's at their low frequency cutoff of about 50Hz, essentially running them full-range, to get all that Heresy goodness. Unless I find a sub with high pass filtering, it ain't gonna happen. Quote Link to comment Share on other sites More sharing options...
willland Posted January 25, 2019 Share Posted January 25, 2019 Both my Revel B15 and SVS SB13 Plus have high pass filters. None of my Klipsch subs do. Find yourself a Paradigm X-30 and convert any subwoofer. I have owned two of these and they work great. Bill Quote Link to comment Share on other sites More sharing options...

I was hoping to find a link for one that is for sale but no luck. Bill Quote Link to comment Share on other sites More sharing options...
Deang Posted January 25, 2019 Share Posted January 25, 2019 It's been a while, but about a decade or so ago, it was pretty obvious that there as a degradation in the sound quality by shooting the full signal through the sub. That may not be the case anymore, but I doubt anyone is using anything but electrolytics in the signal path in those things. Quote Link to comment Share on other sites More sharing options...
Peter P. Posted January 26, 2019 Author Share Posted January 26, 2019 Thanks for the suggestion, willand. I may have to cave-in and accept an 80Hz high pass to the Heresy's, but I can always keep an eye out for the Paradigm. I see there are none currently on eBay. If I used the Paradigm, could I hook it up per the following, with my integrated amp's pre in/out RCA stereo jacks: preamp output > equalizer input > equalizer output > Paradigm low level inputs > Paradigm subwoofer outputs > subwoofer line level inputs and Paradigm high pass outputs > preamp input. That should provide a 50Hz, high pass signal back to the integrated amp, where it would go to the Heresy's via the speaker wires, no?
