Hi Wayne I am considering moving forward on pi4 project.

I have located 1" mdf locally and just wanted to make sure there were no issues with heavier product as long as I compensate with dimensions. I like to build a extra solid box.

That's fine. Just make the box slightly larger to compensate.

Well I have been trying to audition the Pi4 for over a year now and finally decided to just proceed. I have purchased my last 3 speakers w/o hearing them first so why stop now. Smile

Anyway my current speakers are GR Research OB/7 open baffle speakers and I have enjoyed them but looking for something new in a high sensitivity design.

I am somewhat familar with Gedlee's stuff having heard the Nathans on several occaisons. I have several audio buddies running Abbys and rave about them.
I was somewhat nervious letting my OB/7's go cause they are quite resolute, but waf appeal was low. I also was unable to have any room treatments in the family room which is helpful with open baffle design.
I do intend to use the DE250 and JBL 2226 upgrades.

Auditions available in Austin soon. Smile

I didn't care for the glossy shine on the horns so I took some steel wool to them to tone it down. They look much better now.

I wittled away at the horn bolt openings with a razor knife for some time getting the nuts on the bolts. Finally dug out a sanding wheel dremil attachment and made easy work of it on the second horn.

How tight do you attach the compression drivers, just compress the lock washers??

I apply 10ft/lbs. It compresses the lock washers, and then maybe about a sixteenth of a turn more. It's really easiest to do with an open end wrench.

Hey, did you use the two opposing studs/nuts to attach the driver to the horns? Or did you use three? I ask because I've done a ton of these and never had to remove any material. But I know some people do feel the need to remove material to access the bolts. Seems like they are all using the three bolt holes, which are uncomfortably close to the support structures.

I used the three bolt pattern. I realized by lifting the driver up a little it made spinning the nut a little eaiser but im pretty sure removing a little plastic was neccessary. Confused

Hi Nick, Which BGs are those in the new speakers? What crossover freq/slope did you use on them. I ask as I have a quad of BGs here that I never used for a still born project and it might just give me the push to finish it.



Good Listening

Yeah, the three-hole pattern is a bit dodgy. I never use that position because the two-hole mounts work perfectly, with no adjustment necessary.
