60 Degree DIY Mid Hi - AKA PM60
- Thread starter Peter Morris
- Start date
Well see.... just waiting to have them sprayed... and wired up... should get gud results....
When I get some $$$$ I'll invest in a couple of bms drivers, but for now This should work
Should work well.... @Peter Morris said it was one of his options... just have to cross it a bit higher... recommended tuning is 800hz
The 1090 is rated from 500Hz, but recommended @12dB/Oct (or higher) 800Hz. In early discussions with Bennett he seemed to think It would be fine a little lower especially with a higher order crossover .... I suspect you could get away with 700Hz or 750Hz.

Hello Peter, I hope all is going well for you.
I am waiting for cnc pricing atm?.
A question for you, I was looking at the 60/40 drawings & noted the back corners had been angled.
My guess is to allow them to array. Is that correct.

No... I think Peter cut his back corners for personal aesthetics... And would reduce some weight... if I'm correct
It does allow a slightly tighter array pack, but is was mainly for aesthetics as Leon said, to make them look smaller and a little more professional and less DIY.
hi Peter i got a quote back for cnc & they asked for £160 to turn the pdf back to cad before programming.
the cutting is £120 per box plus the ply price ontop
.
still waiting for a couple of other quotes thou.
I can understand why after all the hard work you, Mark & Don don't supply the cad so readily, however when i get them redrawn is it ok for me to post the cad file from the pdf in order to save £160 for others? providing the woodwork shop give me a copy.

- as i see it, I just started the thread, as such it belongs to all that have contributed, but a special thanks to Mark and Don for all their work and input ... and of course SoundForums.

Ps. I don’t mean by you just in general.
Edited cause i solved that one in that time alignment would be the issue?
