So if you mount a driver on a flat sheet of wood the bass response will increase the bigger the sheet is, right? Assuming we are listening indoors the largest the baffle can get is roughly half the width of the room. What is the difference then between mounting the driver on a piece of wood sitting inside a room and mounting the drivers into the wall itself? (And the other side of the wall was also an empty room) Is the idea of an open baffle that you are supposed to hear the rear of the speaker's output reflecting back at you between the space not taken up by the baffle?
I figure the biggest baffle that's domestically feasible would be a 4x8' sheet of plywood, right? But is a 'large' baffle only desirable within a given room size? I'm just trying to get a grasp on this stuff because I figure out of any DIY speaker project I could do, an open baffle has the highest likelihood of actually being finished. I figure I can cut two lousy holes without getting lazy and abandoning the project!
