Cheers, Keith. I think the fantasy is starting to settle down to a basic
design concept. Still not sure what to do with the bass cabs, though...

If I mount the tubular cabs on top, I don't have to mess with the crossover
frequency, making it easier to use a small-volume midrange cab. If I want to
go for the space-age spindly stands, then the mid enclosure becomes a
bass/mid enclosure and I have to get the dynamics right. (If I consider an
open-ended tube as a transmission line, the 400mm length I have at present
equates to something like 200Hz. Quite what significance that has with
regard to whether the bass cabs have to be on axis, I'm not sure yet.)

I like both designs. The main idea is to reduce the sheer space and bulk
that the present speakers take up - their positioning isn't ideal, and
they're a total pain to move around for when I want to optimise the
soundstage stereoferised imaging malarkey. So much so, that they simply
don't get moved. The little stand-mounted cabs would be much easier to move.
That said, the integrated units might not be so bad if they had handles
and/or some sort of glide pad feet.

A third possibility is to make the mid/top units detachable - mount them on
the bass cabs for casual listening, and shift them to the stands for serious
listening. The bass cabs would sit where the current speakers are - they'd
have a smaller footprint and would present the narrow face towards the
listener, making them dominate less.

The bass cab is just a rectangular box at the moment, but I'm going to look
into something a bit more swishy - I'd like to get rid of the parallel faces
to minimise the possibility of in-cab resonances, so the end result might be
an integrated setup that is easy to move, looks good, and doesn't visually
or physically dominate. More design-jockey CAD games to come... :-)
