Does anyone know of a modern, tall, narrow cabinet design to house the old concerto drive units?
I have recently acquired a pair of some of the last produced Concertos in v.good cond. but am very disappointed in their sound compared to what i've become used to in recent years. They image poorly & have a veiled, dull sound which i feel could be improved upon given advancements in cabinet & crossover design knowledge.
It seems to me, that the drive units can do better given the performance of the B110 & T27 in the LS3/5a, & the B139's dimensions would seem to be ideally suited to the modern concept tall, narrow cabinet.

The Kef Cantata was obviously an advancement, but surely we can do better nowadays.

You might have a look at this page. It is written in German but it may be of some use. I am nearly sure that Dave Dlugos will have something on his site.

Just had another thought. You could make a LS3/5a style box with a separate tall thin subwoofer with the B139. I am sure that there are designs for both. See LS3/5a site and again Dave Dlugos site will give some ideas for sub. You might be able to end up with something like the Richard Allan system.

This Idea I think is the best for the old Concerto ie 2 LS35/a units electronicaly crossed over at 100, 150, or 200Hz to B139 Sub-woofers
so 2 stereo amps will be needed.

The KEF C80
Where would it fit in the category? Is it a grown up Concerto?
The units mid range transducer was 160mm, the tweeter was not the T33A nor the T52B.

Falcon Acoustics still have some cabinets left.
One is time aligned for the B139 and other units.
Quoted as a hybrid design, looks most interesting.
Has anybody had any experience with these at all?
The other cabinet may have been made for the B200.
