Hi!
I haven't been active on the Pi forum for a while, but now some questions came up. I'm going to remove the vented LaScala bass cabinet from my Oris setup and use them in a second setup. Since I already have a pair of H290 horns, and Eminence and Beyma drivers for them, the new midrange horn would be perfect to complete the system. My LS is around 23.6" wide so I would like to make the horn a bit narrower. If I compensate this by making it taller, keeping the the mouth area constant, this wouldn't affect the sound much, would it? I would also like to use a plate amp for the LS, but most of these are filtered at 160Hz. Do you think this could work with the midrange horn?

TIA
Frode

Going down to 160Hz for the midhorn is a bit low. If placed in corners, it should do it but just. You'll be pushing it to the eighth-space limit.

More information is available here. Drawings for a cabinet that mounts nicely on a klipschorn are here.

How does one calculate the angles of the wood for making a midhorn ?

Thanks,
Jim

I think I wasn't very clear in my question, I actually would like to know the angles to cut the wood itself for building the midrange horn as documented here on the forum.

thanks,
Jim
