Can two subwoofers reduce a bass problem?

Hej

Once I tried to use a subwoofer in my system but my trouble with 48Hz and 127Hz got worse. Maybe I didn't tried enough to find the right place for the sub. Then I read somewhere that the use of two subwoofers could reduce the trouble with room nodes. Can this be true? Has anyone here experienced this?

Get a miniDSP equalizer on the sub only. You'll love it. :)

Don't try to fix the null too much. If it resists, leave it alone, but clipping the peaks and tilting the bass the right direction (peaking around 20hz, about 1.5 db/octave down after that) will be incredible. :)

Which mini dsp do you recommend Eric?

oh, I mean, without bass traps, nulls are hard to fix. If you get some, then you should find the nulls are easier to pry.

As for which, for RCA connections:

For balanced:

The HD part means 96/24 sampling is used.

Best,
Erik

Thx Eric!

So you think you can use one of these on just the sub only?

Most interesting.

Erk, I have an extra set of rca outputs on my pre which I would use to go the the stereo subs. Would I stick the minidsp between the pre and the subs? Don't need to touch the signal of the mains?
