Amateur question, but that's why I'm here.
I'm helping do a movie night for a local nonprofit that works with people who are blind and visually impaired. When you can't see the screen, the audio experience is what really brings you in and immerses you in the film. So, I'm bringing some extra audio equipment i have at home to set up a better sound system for the night aside from the TV's built in speakers.
The only sub i have is an 8" 200W one which works great for my living-room sized listening area. It has a lot of punch and low end in my listening space, but the listening space for the movie watching area is very large. It's a multi-purpose room that's used for assemblies, lunches, etc. If I had to guess, I'd say 30 across and about 70 feet long. There is a divider coated in fabric that cuts the room in half (30x35), and the ceiling is about 30ft high as well. The fabric divider will be the back wall.
So, two questions
1. Based off of what little I know about loudness, SPL, and how sound "works," as long as the listeners are near the source of the sound, the sub should still be able to provide reasonable bass for a movie at comfortable listening volume, right? If not, can someone help explain why it wouldn't?
2. Are there any placement or setup things I can do to help out the bass if it is a little skimpy for the listening area? The walls are solid concrete with rebar, so I don't know how well placing the sub nearer to a wall to try and "load it" (terminology check?) would do. And I'm aware how those will be for reflections; there are some curtains, flags, banners, pictures, etc. strewn across the walls in this area which should absorb at least some of the reflections from the speakers.
