Hi all,

Small room, nearly 12' square w/11' cathedral ceiling. 5.1 system
w/150W powered sub currently placed in the right rear corner, firing
down onto a wood floor.

I am bothered by the directionality of the sub (it's right behind me)

If you can localize it it's probably crossed over at to high a frequency, or
maybe it's just turned up to loud relative to the mains.

and am wondering if buying an identical unit and placing it in the
left rear corner would improve things enough to justify the cost.

What say you?

The corner is usually the best place to put a subwoofer.

Are teh speakers a matched set or is the sub an add on bought after the
other speakers? It may be that the location you have the sub in is exciting
a specific frequency, very often 100 Hz bumps in response occur because of
room dimensions.

If it were me I would first experiment with the above refernced points and
see what happens.

Get a Radio Shack SPL meter, the analog one and use it to balance the spl of
all the speakers so they match.

If you get the localization problem solved and you still want an additional
sub go for it, just make sure it's crossed over at the same frequency.
Multiple drivers covering the same frequency range means less work for each
driver.
You will run each sub at a lower spl because they add together.


Also, can I just use a Y-splitter coming off the AVR to feed both
subs, or do I have to put them in a series?

Splitter should be fine, assuming they are powered subs.

Thanks!

Tim
