Well, the DCX464s should be here Thursday so I can't wait to get building and measuring. Unfortunately I have to get a new measuring mic. Umik1 work or should I look at other options?
New DIY Mid High (90deg) - AKA PM90
- Thread starter Peter Morris
- Start date
The Umik1 is less than 100€ where I live and it is a real pleasure to use, it is also automatically detected and configured by REW and comes with it's unique calibration file. No drivers or setup needed and works with any operating system. No doubt there are higher quality microphones if you have the budget to spend; but for it's price it's an incredible tool.
For those of you that made this box using these plans.
Where did you buy the grill?
That's the only part I haven't figured out yet.
I used perforated metal sheet from a steel supplier, and had it cut and bent to size in a sheet metal shop, then powder coated.
Has anyone built the 90 with a DCX464 yet? Just got my 464s and was curious about impressions or comparisons to the 4594HE and wondering if there were any changes I might need to make. The 464 looks to be about 19mm wider (diameter) and I know the spacing between the 4594 and the RCF MB12N351s was already pretty darn tight. FYI, I'm using the B&C 12NDL76s for my low mids. Thanks
How much did it cost you roughly?
I checked with a shop locally, their starting price amounted to the total build cost for the box excluding drivers....
Not much ... about $160 USD for a 2440mm x 1220mm sheet -
1.6mm Mild Steel - 7.9mm round hole - 62% open area
About $75USD to get a pair cut and bent and coated from memory.

...and I had enough left over to make the grills for my 4 x PM60's .... a friends brother was kind enough to bend those up for free and I just spray painted them with 2 spray cans - about $12 USD in total.
yeah i know, quickly changed it after the photo
Thanks for mentioning that you found a few errors in my drawings. I am aware that the handle cutouts are inaccurate, but what other issues did you find? I'll try and update them when I can.
For future reference, I think it's best to link to my post rather than to the drawings by themselves. I've tried to keep that post up to date when things change, and I don't always have access to drawing tools without watermarking.

I think your mistaken buddy. I used my own drawings that i did from scratch. but i found a couple mistakes like the top hat hole was too small for example....The handles are perfectly accurate in my drawing

Oops. My mistake.
Very nice work. How do you use these? Looks like they will perform vertical as pictured or you can rotate the horn and stack/fly them in multiples?
If you plan to use multiples, the recommended way would definitely be to array the 60 degree boxes horizontally.
It’s understood the recommended usage format for hangs. My question isn’t clear.
I am asking how he intends on using them? And of course how well they work if used in multiple hangs.
Thanks.

Just wondering if there would be any interest in flat-pack enclosure kits here in the UK. I've just bought a CNC router and I'm not afraid to use it (once I learn how!).
Stay safe all.
