Jonathan, I can’t thank you enough for this series of videos explaining the equipment and your philosophies on how to create something meaningful and thoughtful that engages someone to even greater depths so as to experience the music in greater depth and texture.
I discovered Horn speakers (Lowthers) 55 years ago and even though I have heard lots of other types of speakers never wanted to change them. I play records going back to acoustic 78s right up to CDs and pleased with the results. Multi Unit type speakers I have heard do nothing for me.
Thanks for all the videos you have done about your design methodologies.....while not an OMA customer, my current setup shares most of the same principles and I now am convinced we are on the correct sound reproduction path.
Thank you for the explanation. You inspire me to create noise reproducing devices. That’s general, but I’d love to talk to you about those ideas. Again thank you, Lytehouse Wagnon
Jonathan, although I’m a relatively young audiophile, I much prefer vintage tech and love (good) horns. Is the more direct sound compared to reflections the main reason that horn can portray bigger images than most other speakers, or is there another reason?
Hi Nick, The main reason is source size; the mouth of a horn is the actual radiating area of the speaker, in comparison with a direct radiator which is never as large. This accounts for larger image, greater impact, lower distortion and better image stability.
@@Fluterra OMA is about tradition, engineering, sound signature, culture, luxury and many more things. It's that Ferrari every kid dreams of instead of an BMW tuned with a little more horsepower. It's also about keeping alive a company like OMA, not like their's profits are like Apple company. They deserve the profits, they have expenses, salaries to pay, research and engineering for future products just like for example Campfire Audio which is why I bought theirs Solaris instead of some weird Fiio FH5 IEMs. Also to be able to design, imagine and engineer such a fine technology sound equipment the very lowest employee needs a good salary, he also have kids to feed at his home, he needs a respected vacation to Hawaii, he needs that comfort in his life to be able to have a clear mind when he works at OMA. I don't think you'll understand...
that colouration is called higher order modes and compression artifact oblate spheroid waveguide is the least coloured, then comes conical(edge diffraction happens in conical) OMA should try Oblate spheroid Waveguide horns too as they are kinda like conical in structure
The two can be easily combined, JBL published an article on it decades ago. Turns out that making the transition at the entry to the throat oblate spheroid and have that transition to conical removes all the artifacts from the throat at a slight cost to constant directivity, with out adding in the amplitude losses at certain frequencies that oblate spheroid horns have. Giving the mouth a slight parabolic transition will move the edge diffraction to outside the listening position and aid in breaking up secondary reflections in some cases.
I attended a concert in a round theater back in the early 80's. The theater had a combination of old EV multicell horns with a horn loaded bass driver to handle the seats midway into the theater to the seats in the back of the theater.. The first 10 or 12 rows had Meyer Sound lab monitors that were aimed at us. Since I was lucky enough to have seats close up, I was listening to the Meyer sound lab speakers which also had speaker correction to clean up the distortions. I found out the Meyer speakers also had a horn for the top end.. I took a bathroom break during one the sets, and as I walked to the back of the theater, I could hear a DRASTIC change in sound quality and when I was in the position that the EV multicell horns were aiming at, the sound changed drastically and there was a completely tonal difference but I could also hear a lot of distortion in the 3,000 to 4500 hz range.. it was awful.. So, I can attest to multicell horns as not sounding very good at all. I think the conical horn design may in fact be the better design. Haven't heard them in person but I think theoretically, they probably will..
