AVAA Active Bass Traps

jag, the wavelength of 62 Hz is 18 feet. The only way you are going to stop that is by knocking down your rear wall. There are two ways you can work around this. The first is multiple subwoofers at least two preferably 4. Next is digital room control such as offered with Anthem, Trinnov and Lyngdorf processors. All three companies have digital bass management built in which allows you to use both solutions very effectively. All this other stuff is equivalent to pissing on a forest fire not to mention cluttering up your room.
