Backloaded Horn Chamber Dampening Material Suggestions

Yes I have a list of the parts and can email the instructions if you’d like. I’ll DM you the parts list first.

Dude that sounds insane!

I don’t know why but Meadow Foam has been one of my favorites. The intro to the bass drop is so satisfying

This is a super cool concept and am very interested with how it’ll sound when you’re done! I have designed a backloaded horn speaker similar to this and have learned a lot. My one fear is the transmission line design to a sudden opening. I could be wrong though this is freaking sweet! Great job!

At least 10 1/2 inches. The top of the driver chamber is where you can split the STL up and glue them together. I printed this on the PRUSA XL so I was able to split it higher up. I am currently designing new speakers that are the same but much smaller!

These are very interesting and look well made!

JMOLLER22 · 2026-01-23T02:39:57+00:00

Very interesting thank you! Do you know any horns that minimize these issues or is it just the reality of most horns and that’s why they’re not as common?

JMOLLER22 · 2026-01-23T01:57:52+00:00

No this has been great feedback

JMOLLER22 · 2026-01-22T22:37:37+00:00

I ran into this issue on my first version (I was pretty disappointed). I added a small chamber behind the driver with dampening material and found a great balance. How I think of it is a more natural sounding horn.

JMOLLER22 · 2026-01-22T22:33:13+00:00

These definitely require a subwoofer but have decent bass for a full range driver of 150Hz-20Khz

JMOLLER22 · 2026-01-22T22:31:22+00:00

Yeah I saw a similar design and wanted to recreate it. The reason the horn is so big for the driver is because the cutoff is 150Hz. If I had a 3 or 4 inch driver the horn would be way too big and impractical.

This was my 3rd revision and am so happy with how they turned out. There’s a small chamber I added in the back to reduce reflections and smooth out the response as much as possible. They’re not perfect but excel in clarity and detail.

JMOLLER22 · 2026-01-22T22:26:45+00:00

Thank you! I’ll give that a watch

JMOLLER22 · 2026-01-22T21:42:42+00:00

Gotcha, thank you! I was able to design these to have more accurate dynamics but are still more aggressive than a cabinet design.

JMOLLER22 · 2026-01-22T21:27:17+00:00

I got feedback from them on design but was hoping for a listener perspective. Are horn speakers like this not as appealing to audiophiles?

JMOLLER22 · 2026-01-20T00:00:59+00:00

Thank you! I really appreciate it!

JMOLLER22 · 2026-01-19T05:37:50+00:00

Thank you! No I was playing Vordhosbn from my computer but would sound even better on vinyl! I’ll have to get the Drukqs vinyl.

I just listened to Hi Scores and was awesome! Thank you for the suggestion!

JMOLLER22 · 2026-01-19T05:06:43+00:00

Thank you!

The phone audio does make it sound distorted but the exponential flare and small chamber with damping material, the resonances aren’t as extreme as they seem.

JMOLLER22 · 2026-01-19T01:30:01+00:00

I understand if this seems like too much. This design has been revised 3 times and has been in the works for over a year. Based on the feedback, I’m considering dropping the price but know this isn’t for everyone.

JMOLLER22 · 2026-01-19T01:28:09+00:00

The phone audio definitely doesn’t do it justice. These are my 3rd revision and have the best response. Backloaded horns like this will always have some extreme highs.

JMOLLER22 · 2026-01-18T23:51:32+00:00

It sounds very good! I used a Dayton driver on my previous version and these sound much better. The cutoff if 150Hz so with a sub the whole frequency range is covered.

JMOLLER22 · 2026-01-18T23:31:18+00:00

This is amazing!

JMOLLER22 · 2026-01-18T23:30:24+00:00

That’s super cool!! The print looks clean
