PMC MB2S CLONE

stargeezerme · 16th August 2012, 08:23 PM

Hi

I'm planing to create my own MB2 clones, using Volt RV3143, Volt VM752, Vifa D27TG-35-06.

The cabinet will be constructed from a combination of 20mm and 35mm HDF board.

Im still at the early stage of design with this, and wondered if anyone else has tried the same project.

Thanks

Probably, although you may have better luck posting in the multiway forum.

FWIW, I suspect you could get superior results with a redesigned line (I haven't modelled / back-engineered the PMC's line, but I would be rather surprised if that were not the case).

Does anybody know how they've constructed the cabinet? it has a gap of around 1mm along all the edges........

My guess is that the "gap" is purely cosmetic. When joining panels, particularly when one is veneer and the other is solid wood, a narrow dado is placed, usually on the veneer side. This makes it easier to transition from one material to the other.

HI... ANY SPEAKERS PLANS FOR PMC BB5 AND XB3 PLEASE

THANK YOU!!!

Try the multiway forum, and removing Caps Lock.

FWIW, since this is a commercial product, I rather doubt there are any official plans uploaded, and on the offchance anybody has the exact schematics, the legality of posting them would at best be highly questionable, since they are presumably the IP of PMC Loudspeakers. Equally, to work as PMC intended, you would need to use exactly the same drivers, crossover & construction materials as they do, in the latter case most obviously damping. PMC make their own foam or have a propriety type made for them, so you would need to somehow ascertain the precise damping properties of this and either get hold of some via unofficial means, or adjust the quantities, densities & locations of a more easily available type to ~mimic the behaviour of their own damping.

With all that said, there is nothing particularly novel about PMC's transmission line designs & you could design something similar or possibly superior easily enough.
