Thanks in advance for the good advice and feedback. I have been lurking around for a few months.

Room - 15 X 19 X 8, and is a multi-purpose room (I am jealous of the hall passes some of you have received to build these awesome HTs), The TV is on the 15 side and viewing area is about 10 feet from the screen.

I recently ordered M60's for fronts, and QS4 for the surrounds. Already have an Energy Center that I am planning on keeping for awhile. The M60's will be roughly 8' apart on either side of TV, and QS4s will be on walls about 6' up.

Based on wife "feedback", the sub needs to be in the rear of the room. Currently I have an old 8" down-firing JBL that came in a $399 5.1 kit from BB. I would like to upgrade the sub, but am on a budget and don't know a lot about subs. I want to keep the single line in from the Receiver (Onkyo 606), and will be running sub-cable through ceiling and terminating in a wall plate. The budget is from $300 to $500 US.

Thoughts?

Welcome.

Just my initial thoughts about the sub, in that size of room and the budget limitation of $300-$500 for the sub probably won't be enough.

I will let someone else with an EP120 or EP175 speak up, but you may find a lot more enjoyment out of the EP350 or greater...

Might stretch the budget a little.

There are a number of subs to choose from around $500 US(Outlaw, SVS, HSU, P'Digm) or for a little more, an EP350 through the Factory Outlet. (wouldn't go smaller than that in your room)

Your budget doesn't seem high enough for an Axiom sub. Maybe something like this Parts Express: Dayton 1003K 10" Titanic Mk III Subwoofer Kit will work for you.

HSU

eD or the Hsu.

That eD sub sure looks like a winner. Especially at that price. I might have to bite.
