Room EQ (Page 2 of 2)

I see. Well, if that's the case, I agree with Ash on this one

Whilst the comment regarding masonry walls and the benefits they have as for sound isolation is correct, they have very little absorption at low frequencies, which is why there can be bass issues in masonry walled rooms. Here in NZ where we tend to use wood framed plaster board walls this is less of a problem. But small(ish) rooms will still have modal issues and this is what "bass traps" attempt to address. But low frequencies have long wavelengths and so are not going to me effected by 50mm of foam on the wall or in the corner.

Yes of course it's good. You often see them in brothels and bondage parlours in TV drama.

I think Spanky (Max Mosley) has some!

So the moral of this story then, if I understand correctly, is passive woofers
in the same cabinet as the mids/tweeters, can be a real management challenge.
That certainly has been my experience, but I've only recently figured it out.
I've had four sets of large floorstanders over the years. Back in the day, I had
a bass/treble/loudness buttons on my preamp remote, so could at least cut
the booming when necessary. Not a perfect solution of course, but better than nothing.
I have to say though, I had the same issues with at least one set of passive monitors --
8" woofers, ported design. They could really boom too.

The advantage of a separate subwoofer for deep bass, would be location control,
and level control too I suppose. I've never owned a sub. I watched a friend
try to 'integrate' his with some sort of room EQ software, which he never did get
right for his tastes. The rigamarole I witnessed kept me away from subs.
( He finally just turned the darn thing down, and was satisfied. )

My pro audio friends don't use the DSP on their M-Audio gear. They said
something very similar to what Bull.ed has written on the subject.

The only other alternative worth mentioning is dipole bass, which can help
with the room modes issues -- less total output, about -6db at 30 degrees,
basically null at 90 degrees. It does work. But it comes with lots of other
caveats of course: must be active, ( or huge -- Jamos for example ) requires a larger room, etc etc.
