Looking to get feed back and opinions on this:
With respect to the mid bass enclosures of my multi-way system, operating in the range of 60-250 Hz, and with the largest internal dimension of said enclosure being 23 inches, do i need to use any absorbent materaial, i.e. fiberglass, etc, at all ?
p.s. the crossover slope is 48 db/ oct. (active, of course)

Bingo: Spot on !
Thats is exactly what I was concerned with, and I am going to use similar to what you suggested. Thanks so much for the heads up !!
If you are concerned about box modes ,with that 23" dimension there should be a 1/4 wave mode @ 150 hz. I sometimes use internal baffles @ 20- 35 degrees to any box wall to break up modes. If this is not what you are talking about, ignore this then.

Of course you want something to absorb soundwaves bouncing around in the box. Any design i've ever made has sounded clearer with some good absoptive materials in there. Don't use plain old polyfill or acoutic foam either. Some good, cheap rigid fiberglas attached to the walls or even better Bonded Logic stuffed in there. Just google around for some.
