Besides directivity, 2 important facts with waveguide. First the most important is the time alignment with the woofer. In 70-80's, the woofer was advanced, nowadays no care is given but the waveguide does. The second is the lower frequencies loading. The tweeter can operate at lower frequencies down to 1khz instead of 2khz.
I've done some experiments if you mount the tweeter ahead of the wave guide/cone can give you better effects or actually have it wider apart not so close to the tweeter diaphragm can give you better low end give it to go
I got some B&W 706 speakers and are low dispertion and they only sound good when you are right in front of them. If I do stuff around the room (off axis) they sound terrible. Too muffly! 😅 They are my reference speakers for my speaker building hobby. I make high dispertion speakers and I can walk around the room and still hear highs. 😅
That's likely because a number of B&W speakers cross the tweeter very high and you get a large dip off-axis. Not necessarily that they are low dispersion, just that the crossover point is causing a big mismatch in directivity.
Waveguides have been around for years before Buchardt. They've shown up in the DIY world since the around 2000-ish and Bucharest wasn't founded until 2013. I think the recent prevalence has been the push toward Spinorama style measurements being a high priority for a lot of customers.
It actually rang when you struck it! lol Not that that means it will ring in a speaker....it wont! EVERYTHING resonates! Its a Universal Constant. Do you guys- CSS- make custom speaker terminal plates? With custom engraving?
Yes, all metal with make a noise when you strike it. It is the decay time I'm talking about when I say ringing. The sound dissipates quickly and the energy required to get it to do that is far beyond the forces generated inside a speaker.
@@freeradical6390 Yes they do sell terminal plates that they will engrave for you. You can see them at 8:32 I have them on my 1TD-X's and they are very nice.
I think wave guides and horns are bad because they color the sound. They might be good at sending sound longer distances, making the sound appear bigger and giving a livelier presentation. But that's about it. Not good when you are going for a more natural sound.
You can't just slap a horn on a tweeter and expect it sounding good. You have to design with it, including using specific driver and designing crossover for the horn.
I still use my Car version of the LDx25 that was small batch for sale on car forum many, many years ago. Serial no 1 & 2

I definitely will be getting a pair of bookshelves for me to assemble. Good job people@CSS
Certainly, speaker reviewers love to hear and test the frequency response of that wave guide for sure, like what most on BUCHARDT speakers.
I have Amphions... they had theirs long before Buchardt did... WONDERFUL sound. I think most copied Amphion...

Thank you for a great and concise explanation.
Glad you found it useful
You guys should consider doing an old school 12” high efficiency 3 way floor stander with this new tweater. 👍🏻🔈
How do we model the frequency response of a waveguide when it’s installed on a tweeter?
I got some B&W 706 speakers and are low dispertion and they only sound good when you are right in front of them. If I do stuff around the room (off axis) they sound terrible.

Are you planning kits with these tweeters? I don’t see any on your website.
This is interesting, we want to try it, but unfortunately it's still hard to get here
now to prevent thermal compression, by Creative Sound Solutions :D
What would you say is the ideal side wall distances to the speaker with a waveguide?
No matter what speaker you have, getting the sidewall further away is usually a good thing.
thank you
You're welcome
Ugghhh! Ever since those buchardt speakers came out every new friggin speaker has a waveguide! This MIGHT be a fad.

Wave guides just a in thing that will soon go all away. Pathetic copy cats.

Once the tweeter gets installed into the baffle that “knock” ring will definitely be reduced or eliminated.
@@frostycanada6404 Thats what I said.

Well, i only prefer wide dispersion speakers~

There is no ready product benefit your waveguide.
