Ringing stops when you mount them to enclosure.

Polishing up next
Thanks for sharing your speaker build journey, and
Thanks for reminding me why I use matte finish acrylic urethane on my Baltic Birch cabinets. I am lazy.

Funny, made me smile, thanks.

I think she knows, probably why she actually hasn’t said anything.

Thanks much for commenting!

I know smarter people than me could debate this for hours, I kinda tested the difference in ringing before and after mounting the compression driver, no real change. With the compression driver attached and the horn face face down on a wood cabinet the ringing was almost not there. So I agree that once bolted to the front baffle the ringing probably isn’t a major issue.

But the fact that it does ring, and adding the polyurethane does dampen the horn without being mounted, just adds insurance if nothing else.

Funny. Thanks for posting and I hope I didn’t bore everyone with the details.

I think I like to torture myself! But I knew this would be a last speaker project, at least for a few years. Or until I forget how much work this takes.

Today I worked on the super tweeter assembly.

I had purchased a few pairs of mini banana plugs and receptacles. After painting and polishing I installed the receptacles.

The wire from the crossover to the super tweeter is 23 gauge solid silver, Teflon taped, wire. Standard size banana plugs connect to the driver.

The benefits of this connection is no exposed wires, holds the assembly in correct orientation, and easily removable.

Completed the last major item on the speakers, the platform.

Due to the size, I wanted the platform to roll, and needed to be about 4” tall to get the 18” driver the correct height off of the floor.

So this morning I ripped up some Baltic Birch and built the frame. I used the same 1 1/2” router bit to round over the two front corners to match the cabinets. Installed some inserts for the wheels to screw into. And then wrapped with brushed Stainless Steel. Hard to see in the pics, but the wheels are about 1/4” below the base and so the cabinets can roll.

I’m trying not to critically listen to the speakers yet, only have about 10 hours so far.

But I have been “exercising” them a little. My son and I played some Rap type music with heavy bass. Hitting over 100 dB, you can really feel it in your chest!

Soundstage is really wide, and even at really low volume the energy and dynamics of the music is still there.
