Sub-woofer placement

Post by r***@optonline.net
Anywhere, right? A big woofer came with my Sony sound bar and the best location
I have for it is across the room from the TV and off to the side of the sofa.
Does location matter with a subwoofer? Thanks.

It *can* matter. Stuff like corners, reflective walls can
make a difference.

Well, the thing that came with your sound bar isn't a subwoofer; it's
merely a bass module. There's a difference.

I wouldn't say "anywhere" with a simple bass module, but as long as it's
in the same general area as the soundbar itself it's OK.

A "woofer's" job is to give your neighbor something to complain about.

No, that's the job of the subwoofer. It generates sub-bass.

The job of that little floor-sitting unit that comes with soundbars is
to be a bass module, because the sound bars can't generate bass with
those little speakers.

It's not a subwoofer, it's simply a bass module. If you want sub-bass,
you can add that--but you can't do without the bass module.

Woofers get you down to 50 to 100 Hz. Subwoofers allegedly go below that.

So if one wanted all ranges, they would need a woofer too with subwoofer? :O

I forget who it was, but someone used to make a 70.7 volt horn driver that
instead of having a diaphram, had a bolt for attaching to a wall to turn
the whole wall into a sound surface. When I was in college we used to tald
about getting about a dozen of those and bolting them to the support
pillars in the basement of the dorm. Hook them up to a McIntosh 1000w amp
with a signal generator as input, and sweep the spectrum until we found the
resonent frequency. 'And the walls came tumbling down!'

There's supposedly a frequency around 7 Hz that is particularly
uncomfortable. Car suspensions are tuned to stay well away from it. In
college we looked for a culvert pipe with the dimensions to resonate
there.

"The visceral region of the body objects to frequencies between 300
and 400 CPM."
400 / 60 = 6.7 Hz

I've driven a large speaker from a signal generator and homebrew
DC-coupled amp that could make the cone move in and out once per
second but couldn't find an annoying frequency, although I've felt it
a little around helicopters and large Diesel engines at idle. Maybe I
need
MORE POWER!

If one wants to reproduce 20Hz to 20,000Hz, one needs drivers that are
up to the task and a system that is properly powered and properly
crossed over.

Those small drivers that give you voice for your TV, for example, cannot
reproduce bass well at all. Hence the bass module.

But that bass module isn't a subwoofer.

Woofers get you down to 50 to 100 Hz. Subwoofers allegedly go below that.

You can have a pair of floor standing/tower speakers that produce more
bass than a subwoofer.

It depends on what speakers you are using for mains and what subwoofer
you have and the volume level at which you play the mains.

At a lower volume level you will get your lower bass from the sub, but
if you have mains with great bass and you crank them up they can
override the sub.

You'd be lucky to get below 100Hz with a standard woofer or one of those
bass modules that ships with three piece consumer speaker systems.
Sub-bass is below 80Hz, for sure.
