Adding a waveguide to the Dayton Audio AMTPRO-4 Tweeter 

Great Job. This is still open territory with the commercials, as new drivers are developed. You have your finger on the present. Did you ever find out why the dip at 4500 mhz? Carry on. Thank You.

Well done!

I have had good success with chamfers filling parallell areas around my ribbon. Nothing should be flat parallell. I suggest trying a small add on chamfers to the backplates. They dont have to cover the whole area, I think quarter wave physics come into play here. Also I've had little success with plates or grills. My Fountek plays way louder, deeper and clearer with my add on waveguide. But the stock one has almost parallell areas in the waveguide, so no wonder many thinks the stock waveguided one sounds worse. Its all about keeping standing wave and diffraction effects to a minimum.

Really great video and content. I printed a waveguide for a Mundorf tweeters. I have yet to try adding the fins.

Great video. Learn a lot🎉🎉🎉I will try open baffle with fins. Horn thing is hard to do.

I'd be suspect of the width element as being connected to the 4.8k wonkyness, ... via some quarter wave nulling. Plausible? Curious if this why so many hf waveguides utilize vertical divider components. Way WAY out of my depth here ... pure speculation. Thoughts?

Hi, how did you design the waveguide? Is there some online calculators or math needed or just yolo until you get something awesome? Appreciate any pointers you can give me as I want to design something similar for a different AMT tweeter (for fun) Cheers

With acoustic lenses we could so correct the only weekness off the big amt : narrow vertical dispertion

Would you happen to have a WAVE GUIDE for a Dayton Audio AMT Mini 8?

how is this different than my TPL200 with factory Beyma horn?

I just bought this design. Can't wait to implement it. Is it an idea to shine your light on the BG Nero 3 or the GRS PT2522-4?

also, how did you calculate the number and spacing of the wave guides?>

did you mock up an extended phase plug design that was EXTENDED outward as opposed to concave like yours across the front?

With a modest number of subs ... perhaps more of the focus is on his web presence.

Could the vertical dispertion be widened with acoustic lens ? By orienting the plates gradualy from say up at arond 60 dgr center flat and down also around 60 degr....great job you are doing, will try to adapt it to the beyma amt 150...its original horn is too deep...

phase plug extension...

It really disappoints me when a channel proprietor doesn’t interact with the audience he/she is ultimately trying to attract.
