Ok, this may be a silly question and I'm not sure if this is the correct thread, but if not, I can post elsewhere.
I currently have the Velodyne EQ-MAX10 sub and my game room is about 20x12x9 (est.) with an opening about 4ft wide doorway to the rest of the upstairs. Anyhow, not sure if that matters, but I would like to feel more of the bass vs hearing it. I know that if you get a sub with a bigger woofer, the bass would be louder. Since I'm fairly new to all this and the Velodyne is my first true sub, if I upgrade to say the VX15, how would the bass be affected? I know it will be able to hear more bass thru the different volumes from the AVR, etc., but I really would like to feel the bass more than having it be super duper loud. I'm not sure if being able to feel the bass and hearing it go together, where you have to have one to have the other. Meaning it has to play with the volume loud so that you get the bass loud to be able to feel it more.
I don't really know much about all the bass numbers or graphs, but know that I would like to feel it more. Don't want a black eye or anything

I believe I read that ported subs are good for open spaces to get low hz (which you can feel more) vs sealed subs for closed off spaces which have better sound throughout the volumes.
The new sub, if I can get the wife to accept, could either be upstairs in the game room or downstairs in the living room, which is about 20x12x20 (high ceilings) and is open to the kitchen and dining, very open space. I know the VX15 alone will probably not be enough for that living space, but I'm not trying to shake, rattle, and roll the whole house. Just want to hear the bass better and feel it more.
I saw that Epik was having a sale last week, but I missed it. Was thinking about 2 Legends, but with that price 1 VX15 as I've read is much better. Than I see the new XS30 with dual 15's and has similar footprint as the VX15, so that could be an option as well, but either way, the next sub would cost more than any speaker I currently have, so getting the wife to accept is not easy task

I just would like to hear the bass more and especially feel it more. But don't really want to annoy the neighbors if at all possible or get arrested

I know it's probably better to give exact room dimensions and even a diagram, but I just wanted to ask some basics of bass.
Thanks in advance!
