Introducing myself to the team
« on: 8 Dec 2022, 03:33 am »
Hello All,

Introducing myself to the team,

I’ve been interested in Audio for 30 or so years, I’m reasonably satisfied with my digital front end and amplification. I’m a bit of a DIY person and have modified the PS Audio Directstream DAC based on approved tweaks by Ted Smith the designer and have spent a number of years tweaking my two PC solution based on Windows server 2019 booting with RAM Disk, Lots of effort gone into quietening the digital environment to seem like analogue 😊
My preference is open baffle speakers, most recently I had Pure Audio Project Quintet 15’s with Horn but have modified these extensively that they reassembly nothing like the original.
Well over a year ago I purchased the three tower OB subs. There still unopened and in box. We shifted house not long after purchase, and its taken way longer than anticipated to begin the build.
I started today to make the Router jig, to cut the holes for the Woofers.

I have the cabinet drawings, but they lack detail not showing the woofer fixing hole centres. Any chance anyone has this detail please?
Apologies with the introduction and request for information – appreciate any help

Thanks
John

To clarify, you have the drivers, but can't access them?

If current production drivers, manufacturer's website typically has detailed drawings that would include mounting hole location. Even then, I like to measure drivers themselves as I've found that drawings can be off to some degree.

Am I getting what you're saying correctly?

Hi Peter

Thanks for the interest and reply, Yes correct, I will get the kit out of storage just after Christmas but hope to have the H frames built before then ready to drop in the Drivers.
Before I cut the major hole in the mdf for the Drivers I wanted to scribe another larger circle being the centers for the mounting bolts. When I get the drivers the scribed circle would act as a guide for centering the mounting bolt holes.

If there is a link anyone can share to the manufacturers detailed drawings of the drivers that would be great.

Thanks
John

I think I have some detailed frame drawings somewhere, but I never use them. I always drop the driver into the 11" through hole and use a punch to mark the mounting holes. That way I know it is exact, and about the easiest thing to do is to use the woofer for the pattern.
