#1 project x diy speaker build

Post by jayman67 »

ok after reading the roy allinson papers and understanding some of it i bought these at the local charity shop to have a bash at diy speaker building.
at the moment i have no firm plans as to what i will end up with so some guidance is needed from you chaps please.

here's the donors,a pair of richard allan pavane speakers.
12inch woofer,8 inch mid and a 4 inch tweeter.
i dont profess to know or understand speaker crossovers or calculations so perhaps it would be best to stick to a 2 way design,i can on the other hand solder,iam also an ex cabinet maker and now im a steel fabricator so making the cabinets is the easy bit lol.
oh and dont hold back if you think the drivers arn't worth the hassle please say so,i had a quick listen and they are very reminiscent of ditton 44's

Why not try them on an open baffle?
Could be very good.
Steve S is 'yer man for knowing about vintage drivers like those.

I was thinking about this and there are a few questions I could ask -
Have you listened to the speaker as-is ?
If so what do you like about it and what don't you like ?
If it doesn't work, have you listened to the drivers and do you like some or all of them in isolation ?

If all three drivers work -
Is the cabinet sealed or ported ?
if sealed then I'd stay stick with the bass unit in that enclosure, maybe brace the box a bit more.
If you like all the drivers, a good thing to do might be to bi-amp and run the bass off one amp and the mid/treble off another.

But really the speaker will have been optimised with its three drivers and the crossover refined. Maybe you just need to renew the caps in the crossovers and listen to it first ?

What kind of music do you like best and would need to sound right ?
