I've always wondered about the entrance angle on those larger SEOS waveguides (the 18 and 24). What are the angles? There was much discussion...
Look up bwaslo's CoSynes, which I believe are documented on this forum.
Did they say if that's the half angle or the included angle? If it's going to be a different angle imo you'd be better off with a shallower angle...
Re: SEOS fit CD10Nd and CD1014Nd..? A quick search didn't turn up anything, but here's a link to the exit angles a various other drivers:...
I use a bit of everything :o The in-room data I referred to was done in REW and ARTA showed a similar result. The outdoor was done in Holm so...
The thing I've found with a 200-300hz gate is that the resolution is quite low. Yeah, you get data but it has a way of masking what's really going...
Here's a shot of some of the measurements I did with a centered vs. offset port. These are the 4" closed back Celestions that Danley uses. They're...
I was gonna mention that..... It's what I did after I had everything built and it wasn't working like I thought it should. It would be interesting...
One thing to keep in mind (I think someone mentioned it) is if the port is offset from the mid driver center. I've got a set of Paralines (another...
Thanks for the reminder, I forgot about that thread over there already. Good stuff! My Paralines are 10" tall and the eye is sized hopefully to...
JackNC - sounds interesting, guess I wasn't thinking outside of the box! I wonder how that would work with equal path lengths and equal energy...
I don't think that would be easy at all, and I'm not sure it would work. The mouth on a "typical" Paraline is about 10" tall x 1" wide. The...
How about a teaser? Crappy phone shot. The horn's made out of cardboard hardened with polyester resin. It still flexes pretty good, I'm trying to...
Here ya go, based on the original Lambda Unity I think (not mine!):...
