I had an idea of using a bass drum shell for the basic case for a lightweight extension speaker cabinet?
A 20" diameter x 10" deep drum shell has a cubic volume of 1.8 cubic feet and a pretty close to the volume of my Princeton.
There's not a whole lot of difference in surface areas but the cylinder has a slightly smaller surface area and a slightly larger volume ( a 19" diameter x 10" deep cylinder is an optimal match, but they're not made!)
I can buy undrilled drum shells here in Australia. Is this a idea worth following through with?
Has anyone done this before?
Any suggestions?
Cheers John

@John
I have never done that before, but It reminds of a story I read about speaker enclosures when I researched making speaker cabinets for bass guitar.
There was a man that reasoned, "people like the sounds of violins." So he made a speaker cabinet shaped like a violin. All the music that came out of the speaker cabinet sounded like a violin.
another thought
There is a difference between music production VS re-production. Therefore, what read about audiophile speaker systems my not apply to musical instrument speakers.
My opinion. If you got the money and time, try it. You may like it, but don't be surprised if you are disappointed.

A good bass drum shell will have quite a bit of resonance of its own. I dont think that would be the best environment for a speaker
I would think a stiffer enclosure is a better solution

The 59 Fender Bassman had a thin baffle approx 5/16" thick. This active baffle is said to be part of the notable tones this amp will produce. The early suite case amps were also very sonically active. You could play with different baffle and back boards with some time and plywood. Who knows...give it a try.

Sounds interesting. My only caveat being, how do you plan to carry it? A standard enclosure is usually square and has a top handle for transporting. You could attach a handle, but it would be affixed to a curved shell, making it possibly weak to have the handle remain fixed.
