It's easy. Take the internal dimensions of the alloy cup. Take the dimensions of the driver then divide the difference by two :grinning:

Here try this guy http://www.head-fi.org/t/754838/aluminum-sleeves-for-grados-magnums

I bought some spirit labs cups and bought some alloy sleeves on here from a guy who had loads .the drivers then slide in beautifully and you can use the threaded holes with M4 grub screws to hold the drivers in place. I'll have a look and see who I bought the sleeves from if you like

What if you skimmed the excess wood of and then open up the grill( more open weave ) to compensate for the fact that the driver is to far in ?

Any body fancy some unused V4 drivers by any chance :grinning::grinning:

I bet you get a nice controlled snap of the bass as it were.and yes I bet you about the space.its like the music is being restrained within the chamber and then whoosh of it goes in to ones origins of the brain.a pleasant smile appears on ones face almost of euphoria lol

Sorry forgot to say there brand new not even been soldered. They turned up scratched . Apparently it's the paint at fault

Any body fancy some V5 drivers by any chance.

That's ok we are all here to help and in search of the same thing lol

Ah ha now you see him now you don't lol

Nice to enjoy music as it was intended.im sitting in my garden listening to my ally Yplison and every second I'm getting blown away by how they sound :grinning::grinning:

Ok cheers for that.imfound it the other day.

Nice touch man :grinning: How do they sound ?

Oops I've just ordered some more Yplison drivers to see what they sound like in my ebony wood cups. The more I listen to the all alloy cups the better they are sounding.im listening to Pink Floyd and i can't believe how well they behave.i was at there last tour some years ago.if I close my eyes...

Your most welcome. Anything to help

Ok so now my Sunday build is done after having my yummy roast. I've only listened to the V4 ally cups with mahogoney sleeves for about 10 minutes but yet again I can't get enough of the sound that they produce. They are some what darker than the Ypsilon drivers but they have that warm glowing...

Not as yet but will let you know
