SUPRAVOX 285 GMF cabinet size

nirvana · 26th January 2009, 02:36 PM

I would like to know what is the best cabinet size for the Supravox 285 GMF woofer. for better bass possible.

FS 47 hz QTS .38 VAS 150L Claude

Basrefleks should make it straight to 50hz
120-140 liter netto, with BIG slotport 100x400mm x100

I tried calculate with 275 liter and just a 100x400mm slot opening, not a port...pushes it down to 35hz
Have been used a lot in PA

Could be its a woofer well suited fore ONKEN, I dont know...but its suggested on Supravox site...dont know if its the optimum

You don't specify exactly what sort of cabinet you're after, and 'best' is at, er, 'best' a subjective term, so we're going to have to wing it here.

Something like this MLTL ought to get you started:

42in long, CSA 221in^2, Zd = 17.625in, Zp = 38in , vent 4in diameter x 1in long.

CSA = cross sectional area
Zp = distance of port centre from the internal top of the cabinet.
Zd = distance of driver centre from the internal top of the cabinet.
