Here's another idea:
I think the room treatment / equalisation subject is woefully under-represented in most magazines. Why not do a 'room doctor' feature?
Some measuring software, a selection of room treatments, a couple of equalisers (or some dealers wishing to lend you the kit) and away you go.
A different victim, er I mean reader every issue. They don't all have to be complete loons (although they to read HiFi+), some people may even resent the idea of huge bass traps. The wider the cross section, the better. I think this would be of genuine interest to most people I'd have thought. I'd pay to read it anyway.
And if it makes it any easier; some of those equalisers are really really expensive too, take the Accuphase DG38 for example, blingtastic.
