Every bass driver I've ever seen in a catalog in the past 40 years, from 6" diameter to 18" in diameter, was capable of relatively flat frequency response to 100Hz.The few 18" B&C drivers I recall were capable of 400Hz.
There is no "boundary reinforcement" in most rooms between 15 and 25Hz.
If no two walls were 22.5 or more feet apart, there would be no standing waves under 25Hz., and therefore no "reinforcement" from the room at all.
Placement alternatives for a bass speaker in such a room would have no effect on bass output below the modal zone (under 25Hz. in that theoretical room).
If there were two walls 22.5 feet apart, there would be a standing wave that could "reinforce" a narrow band (perhaps 5Hz.) of bass frequencies centered at 25Hz.
If there were two walls 37.7 feet apart, there would be a standing wave that could reinforce a narrow band (perhaps 5Hz.) of frequencies centered at 15Hz. (assuming any output from the bass driver at 15Hz., and any 15Hz. output in the music content at a high enough SPL to be audible -- both very rare).
You are completely brainwashed by REL advertising literature to the point that you can't even call a 10" sealed REL subwoofer a "subwoofer", simply because REL uses a different marketing term.
