Default need quick help with A10.3 info !

Hi, I'm about to cut into the front baffle but the drawings on the downloadable pdf for the Alpair 10.3 are nearly useless - they are so small and fuzzy I can't read the data from them. Anybody have proper and reliable dimensions for the cut outs needed for this driver (with bezel) into 17.5mm birch plywood ?

As Jeff says, you could just zoom in on the PDF drawing, but short answer is with bezel:
OD = 165mm
ID = 139mm

rebate depth ( Z)= 11.8 ( test to allow for minor compression of molded gasket)

without bezel:

OD = 160mm
ID = 139mm

rebate depth = 10.5mm


If you're planning on CNC routing of the rebates, I'd suggest allowing at least and extra .5mm dia on both through hole and recess for ease of installation / removal of drivers - if they're too tight and you need to force them to fit, you're asking for trouble - and of course if you ever need to remove the driver

Thanks boyz. I downloaded the pdf and tried the zooming but it isn't great and I don't want to get it wrong. There was a slightly better drawing on the Madisound website.

I will indeed allow some extra clearance - good tip.

hmmm, rebate of 11.8 out of a piece of 17.5mm Birch Ply leaves only 5.9mm for the screws to bite into. I may consider adding another pice of ply to the back of the baffle at the top where the driver goes.

Ah, yes.

I always back up the baffle to a depth of at least 24mm. The A12's are worse. At the moment, I am using 12mm BB for the baffle with a 12mm gusset backing up the baffle.

The original drawing(s) imbedded ino the MA pdfs are here. Except for the addition of the optional bezel cover & super gaske with the A10.2 baskets are the same across all 10s

I've just finished milling the panels for the A12.2P Pencil from 3/4" Baltic Birch ply and am backing the inside of the front baffle with a square of 1/2" ply so that the screws can bite into approx 3/4 inches after rebate....

don't forget to chamfer the rear side before assembly!

Indeed Chris! Honestly, I was about to type that very suggestion (requirement, really) but got very hung up on spelling that "Ch" word, so I didn't! I commit to memorizing the spelling for future posts.......
