Help me out here Einstein. What is that you don't think I understand and explain it to the rest of us. If it would not be educational it would be very entertaining. Have at it. This will be fun.😀
Are you all worked up because of what happened in GA?
I don't built enclosures. I buy them. If I were to design a driver I would do it with two friends and my brother in law who was a lead M.E. with United Technologies who worked on projects very complex projects and my two friend one who has a PhD in math and physics and the other who is a self-taught engineer. Like you and other fanboys I don't pretend to know everything. I go with the experts.
The fact is speaker efficiency has not improved in 40 years and you can't explain why. Can you? If so explain why. If you can't just keep being an ***.
If I were going to design and build a driver I'd think outside the box.
There has been tremendous development in loudspeakers over the last 40 years, but efficiency is always a tradeoff, mostly because this thing needs to work across a relatively wide range of frequencies.
Feel free to go find some PhDs to develop your "magic speaker" that will be worlds better in terms of efficiency. From a live sound perspective, nobody is going to care. Class D amplifiers have come so far in the last 10 years that it almost doesn't matter. They sound good enough for studio monitoring, they're reliable enough for the road, and they're big enough that a single 2U amplifier like the LA12X (which weighs about 14 kg) can replace what would have historically been 8U of space weighing about 150 kg. Powersoft has some similarly insane amplifiers in a 1U chassis.
I guess I just don't see the point.
Have you presented your ideas in this thread to them? I think we would all love to hear their comments.🙂
The best sounding concerts I've been to are Pink Floyd in early 90s and the Grateful Dead in late 80s. I think the Dead was using an early Meyers line array at that show.
Some of the best playback I've heard was in a nice wooded outdoor setting. Total diffusion and no standing waves. If we could some how find a much larger version of that space, a decent modern mostly horn loaded system would work out well.

you can't cheat physics...and i'm with Discopete i would like to hear what HoundSound's highfalutin friends have to say on the subject....
OK sport, tell us about all the great speaker innovation in the past 40 years made by the manufacturers. Make a list.
In the meantime try to keep up with the discussion.
As to class D amps, a lot of audiophiles don't like them so the notion of pushing huge amounts off wattage doesn't fly with everyone.
Before you spew anymore BS do some research. Best Stereo Amplifier Reviews (DEC. 2020) – Guide | AudioJudge
The notion of putting 3000 watts into a speaker to get a adequate SPL is kinda crazy. Where does the power come from to power these amps the magic Ampere fairy? Amplifiers require electrical current.
Your task is to make a list of all the loudspeaker improvements since 1990. Have at it sport.
Your next task is to do some research and explain why loud speakers are no more efficient than they were in the 1980's and after that report back with scientific facts explain why speakers must remain woefully in efficient. Then you will be entitled to an opinion. Until you can add to this discussion something factual and scientific rather than snarky ignorance, remain silent.
While class D amps have improved in sound, they are still not the best sounding amps. Guitar players prefer tube amps for reasons I don't have enough time, patience or a big enough box of crayons to explain to you. Given the technology that exists today, I would use tube amplification for mids and highs for an audiophile version of a PA or I would use a tube preamp.
They work on things way beyond the pay grade on people in audio engineering. I wouldn't waste their time.
While I got you here, can you show proof as to why:
1. Loudspeakers can't be made more efficient. Show the math and science no BS.
Tell us:
2. What is the current efficiency of modern loudspeakers.
Tell us:
3. What is the theoretical efficiency of a loudspeaker?
