Not manufactured any more.

Mark Levinson HQD since people seem to like his stuff, which is not very good.

We made some of the stands for these AND the Hartley 24" woofer cabs.  HUGE!

OR, Bob Fulton's J system.  The FMI 100's were not bad for boxes; this system came with the slightly smaller FMI 80's, which were pretty good as well.  I would guess they hold up today as well, although there have been improvements in boxes since then.  If you like box speakers, that is...

Sounds like boxes are pretty dreadful!  I wonder why so many cost-no-object designs use them? ;)

But back to our regularly scheduled programming!

One set of designs that ought be much missed by DIYers (and everyone else) are the kit speakers from George Short at North Creek.  Mostly pretty basic MTM or two way designs, with top quality components, often voiced to be placed quite near boundaries (very helpful for many of us), and sold at real world prices.

Below is is somebody's very attractive build of the Big Kat. The smaller, and still very good, Eska was one of my first serious speakers, with figured walnut boxes built by George's colleague Lee Taylor.  They still serve admirably as the fronts in my small home theater.
