I have been browsing this forum for quite some time. Having been very intrigued by VMPS' first line of speakers in '77 or '78 (those suckers really put out some bass), I have a question regarding the driver configuration of the RM40.

I continue to question why the mid-bass driver was put up close to the ceiling. Actually, if it were closer to the ceiling I think that might be good however, hanging somewhere about 6 feet from the floor and 2 feet (on average) from the ceiling, I think that the mid-bass reproduction suffers.

I know this has been discussed in the past but I wonder if Brian will at some time try a different driver configuration with the mid-bass above the bass. I know how critical driver placement can be. An old pair of Allison One speakers I owned many years ago put the bass drivers close to the floor for this very reason (bass frequency extension).

Any ideas regarding this?

well it looks as though the RM40 cabinet design is pretty much set in stone, especially now that MLS took up production of cabinets and they are the same config.  I wondered if the advent of the RM/X would make BC ponder putting the midbass on top of the megawoofer then a 4 stack of mids with an adjustable tweeter pod on top of that.  Guess not.
