Frankenplanar speaker: Acorn ESL / Maggie ribbon tweeter hybrid

Inspired by StigErik’s hybrid Magnepan speaker project (please come back StigE if you are reading this) I’ve decided to put together an unusual hybrid speaker system comprising Maggie ribbon tweeters, ESL mid range (cut out of some old gen 1 Acorn panels) and OB woofer arrays. The ESL mid range will use a 3 micron diaphragm.

On paper it probably doesn’t look very sensible to mix 3 different transducer types but I’m in a position to try it without going to enormous expense and so why not give it a go. To maximise the chances of success I will be using Audiolense for the crossovers etc.

Still in the planning stage but I will post updates as I progress.

So a question regarding the mounting of the Maggie tweeters. I’m considering 2 options. The first option is to flush mount the tweeter cage in a relatively narrow width wooden baffle. The other option would be to suspend the cage from a frame so that it would be baffle-less. In any event I’d then fix the tweeter structure so that it is vertically adjacent to the ESL mid panels.

I’d welcome observations on the relative merits of the 2 options.
