VTF3-MK3 Can it pressurize a room.

[rutgers1]

My room is 16x16x8 with many windows unfortunately. It seems that the PB12-Plus/2 and the PB12-NSD/2 are routinely associated with the word “pressurize”. I know exactly what that means . It is an unbelievable feeling that everyone should experience at some point in their lives. I would love to be able to recreate that sensation and was interested in the VTF3-MK3 + Turbo. Is this sub up to the task or should I be focusing on the PB12’s or the VTF-3 HO?

If you can close off the room, I would say yes without question. The bad news is, that room is square in footprint and 1/2 measure in height which is not going to be good for bass response.

Well, I can't move the walls or the ceiling. It is what it is. Would treating the room (acoustically) help? The wall that will hold the TV has a standard (mostly) glass door on the corner. The opposite wall has bay windows (3), the third wall has a set of Frech doors. The other wall is fine.

The good thing is that the room can be fully closed in. So, I'm looking at ~2000 cubic feet. Considering the additional information provided, is the situation now better or worse?

I wouldn't say better or worse with that information, but closing it off is a plus. I would say treatments would be a benefit for sure, but choose the sub, get it in and then you will probably want to pick up a SPL meter so you can run some numbers on it. Then you can determine how good or bad response in your particular room is and decide if treatments and/or EQ can solve the issues. The reason a square and near square rooms are not good for bass is becase of the wavelengths of bass frequencies in the bottom octave - they will reflect and overlap (standing waves) and potentially cancel out at particular frequencies because they cross at perfect angles. You can't move the walls, but you can adjust how the waves behave in the room with treatments. I have also seen others adjust the dimensions of the room with a false wall (basement, dedicated HT room, etc...), though it doesn't sound like that would be a viable option in this room.

I heard the VTF-3 Mk2 in a room that was about 18x14x8 and it had no problem delivering adequate bass.

Yep....drastically. Room treatment is a necessity in every listening room.

Hey rutgers,

The VTF-3 Mk3 should be able to pressurize that room pretty well. If possible, try to keep the subwoofer in the nearfield (either sideways behind the couch or next to the couch), or at least keep it away from the windows if possible.

I would normally run the Mk3 in max output mode (both ports open, no turbo). Turbo works best in systems that use MBM-12.

Sincerely,

Pete
