here's a fun question...

[theoilweapon]

Hi all. I'm a college student on break and before i left i spent a whole day with my roomate reorganizing. The room has as very odd shape. Kind of like the classic cut for a stone (like a diamond) in a ring. Furniture is in the acute corners right now. So the only room on the floor is about halfway in between two corners. What would happen if i place the VTF-2 :eek: on top :eek: of a dresser (which is in a corner). What would this do to the sound? I apologize i can't describe the room better. The dresser is about 4 feet above the floor.

Who needs photoshop when i can use "print screen" and "paint" ;) That's approximately what it looks like. The X is where the dresser is.

I Wouldn't recommend it.

How stable is the dresser? Will it vibrate when the sub is firing? Wouldn't it be difficult to get to the controls on the back? Why can't the sub be placed on the floor where it belongs?

The dresser is very sturdy, and the controls could be reached without getting on the floor. But i think you are right, the drawers would vibrate. Do you think it would be better in the corner up high, than in the middle of a wall down low? :confused:

Corners good...middle of the wall bad. At least acoustically. Not the end of the world, but not optimal. If your room is under 16 x 20 or so, the VTF-2 / STF-2 should sound good in a wide variety of places.

Another good place is to put it right next to the listener in the back, if you can get wires back there that is the bomb.

Reasoning is that in the corner, all the room modes are excited. If you want to hear bass boom to the max, then that is the place to put it.

Middle of the wall placement means the odd order modes would be cancelled out, thereby eliminating much of the potential bass boom.

Do you mean to put the sub just behind me to one side, Sasha? Like near one of the back legs of my desk chair?

Thank you both for the clarification, I never really knew why the corner-placement was so popular.

Yes directly behind where you sit.

I will be sure to try it all out, thank you for the suggestions.

Tom Nousaine did some research in a variety of rooms, and found that corner placement did excite more room modes, but that the bass response was MORE even.

That was a very biased study there to perpetuate his cause. Corner placement would probably be the best place if you compare it to some randomly selected position. But it is never the optimal position, since that would be different for every situation. And once you find that position, it would almost be guranteed to have better sound than the corner.

Unless you have room length that is 30-35% the width of the room, you 1st or 2nd order standing wave will peak together, creating a double peak. And to get room modes to smooth out, you better have some very flexible walls and floor, since high Q peaks don't usually combine together to become a flat response.

Floyd O'Toole's team did some extensive study of sub placement, and they don't go about recommending corner placement.
