What are your exact settings for volume and low pass filter on your SVS sub?

Original poster here. We're starting to get a lot of variety now. I forgot to mention I have a bright, large, complex room and I listen to a variety of musical genres and route films through my system.

If I turn up the volume past -18 or so, there's way too much bass. If I go the other direction, the difference is more subtle. The helpful guy I talked to at SVS suggested ten Hz over the listed bottom end of my ATCs, even though this was based on -6db. By trial and error, that's what I've ended up with.

My sealed speakers do great bass in my system. They just don't go down as low as some, thus the subs.

First, if you haven’t already, use the “crawl method” to find the best location(s) for the sub(s) in your room for best bass…

Then use this to fine tune your sub’s individual controls…

Using these techniques should give you a high degree of confidence that your subs are dialed in well. Hope this helps, and best of luck.

I think you have the right idea but beware of using the published specs to determine how low your main speakers actually go.

Try to play a test track with defined frequency levels from Quboz or from wherever and hear how low your speakers will actually perform.

Then, set your sub crossover to enter perhaps a little lower than your main's will actually play.

Thanks, all.

I crossover at 85 hz, THX recommended crossover.  I, however cannot argue with 40 or 50hz.
