Right cabinet for these vintage Coral drivers

[atilsley]

have sourced the following vintage components from Coral -

a 12-inch bass unit
4 inch mid
two alnico tweeters

I have a large ported box using a 4-inch port, adjustable to approx 12 inches.

Can someone reccommend suitable cabinet tuning, port tuning? Alternatively, what sort of box would these units have come from?

Cabinet is approx dimmensions 800mm x 550mm d x 400mm w.

Regards. Andrew.

Hmm...

Vented dust cap, steel basket, small motor...

might be just right for OB.

Is that an inverted surround?

hi atilsley

the old box is suitable for your 12". Please believe me,don't pay more for OB. OB is no bass=No metal rock concert in your home or the other words u may have wood rock concert in your home. okay it may be good for planet10 because he is afraid that his heart is high beating. but u and i,we are the rock and we are the champion. r u ok?lol
