Why aren't there more waveguide tweeters?

Re: Why aren't there more waveguide tweeters?

Oh that is so cool!

I would think with a 12" SEOS waveguide you'd want a 10" woofer, though. (Assuming a 90deg WG; if it's 60deg then a 12 makes more sense.)

i want one........no two.:D

Re: Why aren't there more waveguide tweeters?

That would be very helpful wolf. Thanks.

3.3125" or 3 5/16" is the 1.5" diameter-exit depth position from the face of the Dayton round 8" waveguide. If you add back in the thickness of the material if a straight-through bore is used, it's about 3.5". If the cut is across the throat, then the 3 5/16" is the dimension of depth.

Re: Why aren't there more waveguide tweeters?

For anyone who has used the 8" dayton waveguid, once it's trimmed to say 1.5" diameter opening, how deep is the WG? Is the AC of the tweeter going to be very far behind the woofer?

Shipping 1 waveguide to Canada is $35 :( I'm not going to be in the US until Christmas likely. Don't wanna wait that long. So if anyone can sell me them with first class shipping, I'd appreciate it. Hoping to hear from Solen about them.

Any other waveguides I should consider?

I'll get mine out and tell you when I get a second...

The SEOS tests better than the Gedde's OS so there's no need to go larger if it will handle the crossover point of it's matching woofer size. It's a 90/60 waveguide.

Re: Why aren't there more waveguide tweeters?

Here's another idea I'm still working on. Pay no attention to the dimensions as they will be available for all different sizes once things get moving.




Hoping to have it all figured out by late fall. There will be flat packs made for them as well. This was the goal of Zilch and I from the very beginning so I REALLY want to make sure I get these completed as soon as possible.

Re: Why aren't there more waveguide tweeters?

Ok, great feedback. Thanks all. I think I'll have a go with the 8" Dayton. Now if I can just find it in Canada. Don't want to pay $20 shipping :o

Doesn't B&C have a .75" CD?

A .75" CD doesn't seem sensible for PA application but I think it would rock for a small hi-fi speaker... especially with a well damped titanium diaphram.

Re: Why aren't there more waveguide tweeters?

Interesting. Is there a specific tweeter for which it's designed, to avoid reflections at the mouth?

The medium and larger sizes were initially designed for the DE250 compression driver and tested extremely well.

There are a lot of interesting things I'm trying to get done that revolve around the SEOS design. The smaller sizes will eventually be available for regular dome tweeters as well. It just takes a little while, but I am spending a decent amount of time getting it done in the background.

Re: Why aren't there more waveguide tweeters?

I'd love if there were a 3/4" compression driver that could mount in there.

Also, I think a dome with a flattish profile and a "snout," such as the Aura NT1 would be ideal. Though for output reasons a 1" dome may be preferable.

Parts Express offers an interchangeable truncated faceplate for their Usher-built RS-series tweeters. I wonder why they haven't designed an interchangeable waveguide faceplate, since it's very easy to swap the faceplates. It seems there would be enough demand for them, and they'd have the waveguide-dome product category all sewn up.

Agreed. I know I'd buy three to tinker with.

I personally like the way the WG looks carved directly into the baffle.

Me too, and that's definitely the lowest-diffraction solution. However, many people who can do the math can't execute the woodwork, and many people who can skillfully execute the woodwork can't do the math. That approach also makes experimentation more expensive.

Re: Why aren't there more waveguide tweeters?

Hmm, that does look nice.

Any idea how much you'll be charging for what ever creation you guys come up with? I haven't read the whole thread, but haven't seen any pricing either.

I can't say for sure. I'll let Ed figure out his time commitment to each piece before I'd speak for what he'd like. I know others are looking into having the guides duplicated as a bolt on. I personally like the way the WG looks carved directly into the baffle.

Re: Why aren't there more waveguide tweeters?

That's about as low as you can go with the 6" elliptical waveguide before it takes on some of the negatives of waveguides such as a honky sound in my humble opinion.

Dang, too high. Thanks for the feedback though.
