Of course this was a DIY/artisan project, but perhaps due as much to use of SEAS Excel series drivers and less than stellar XO design as to the enclosure materials, it was as musically moribund as it was acoustically inert - it made sound, but there was just no synergy.

what about this?


over engineered?

dead?

Not in the sense that Chris means. And from the picture, likely under engineered for the energy it needs to contend with.

Does give you an idea of how big a bass horn needs to be. If one assumes free-air use, extension limit on the bottom estimated at 35 Hz (if the female is 5')

Will require digital delay.

maybe we need to use some concrete to make it truly inert?

Concrete's been done too, by at least one (short lived) commercial venture.
OTOH, anyone remember the various Rogers speakers?-- they were the furthest thing from inert, but they made music!

certainly an extreme performance concept - over-engineered to the specific goal? who knows

"dead"? - quite possibly not -
does that matter? - sorta my point - were is the threshold at which striving for that becomes a diminishing return?

don

or DCM Time Windows / Spica SC50 - essentially sectioned Sonotube with particle board baffles and solid wood end caps -

or British Tangent speakers circa 80s - thin and strategically braced

It would be if it were made of concrete. I think I see a seam in the wood on the top.

dead as inert or dead as in frivolous attempt?

it seemed the original statement indicated inertness of the enclosure.
