Here a three way horn system I'm fabricating. The larger horn is a bass/mid bass unit (50hz to 250hz), the smaller horn in the upper left is the midrange unit (250hz to 6000hz) and the tweeter horn is a sweet sounding Fostex.

The midrange horn is paper mache. The bass/midbass horn is solid maple. The drivers are Ale.

Amazing work. But the horn mouths, shouldn't they be bigger? I use a hoen from 440-2000Hz and the mouth is about 80x50cm. Any measurements?

Here's an RTA of the bass horn. I don't have one of the midrange, yet.

This was taken using pink noise, with only the floor boundary. There were no side walls.

Simple pair (prototypes) of my own ml-tqwt designs. Same drivers used as my previous "table top" reflexes: Vifa bc25sc55 and modified TB w4-992s.

Neutral is the word for these. Easy to listen for a long perioids, bass extends down to 40Hz easily and there is good amount of it.

Amazing construction!
How did you fabricate that?
Do you have some pictures of the process?

Nice work. The floor concrete bass horns with Altec 515 sound great. How low do they go?

Looks like a lot of work. Well done.
