Emerald Physics: Same as the Quads in the fifties?

No. Even today Quads are matched or bettered by very few loudspeakers in the midrange. Not to downplay the Emerald products, but if they were as remarkable as the Quads you would see a lot more press coverage. If you really like them, and only an audition will help you determine that, then buy them and be happy, because in the end it doesn't matter what anyone else thinks as long as they provide the music listening pleasure you seek.

very nice speakers, but we'll have to check back with you in 40 years to verify if they were revolutionary.

I accept the fact that you're honest, but I honestly don't take your statements that seriously. Along with the original AR turntable, the Altec VOTT and one or two others, the Quad 57 is a true landmark product. I don't see anything remotely suggesting that the Emerald Physics is or will be a member of that group. Over time my opinion will be proven right or wrong. Two things I am right about, today, is that you called the EPs revolutionary and characterized their performance as remarkable.

BTw, I too have never heard the Emerald Physics, but they appear to be a very interesting design that offers high value.

Onhwy61, with all due respect, you're still misrepresenting my statements. I did not say EP are revolutionary. I commented on the answer of another audiogoner, and said that his answer seems to suggest EP are revolutionary. There is a big difference between your characterization and what I actually said and meant. Again, since I believe that products like EP are likely to get negative reviews when they come out (most dealers do not carry them, most speaker companies would be in trouble if they were truly revolutionary) I just wanted to hear the opinion of people who had tried them and experienced them. That's all.

Klangfilm and other companies made similar designs in the 40s 50s. Nothing at all revolutionary about this design. The only thing is using DSP to get bass out of the loudspeaker. Takes modern tech to do that but I prefer generating bass without DSP EQ. To me that's like a band aid. A way of making loudspeaker smaller more affordable. I would listen before you make such bold and wrong claims about this loudspeaker. Sure they can sound good but a proper designed compression horn system with tweeter and proper bass will sound much better but also will cost more. Does seem doing things right from the start costs more. But for the price the EP is a good deal. Not ground breaking best in world or any such nonsense but a well designed affordable loudspeaker. Weather you would like a EP in your system is all up to you. Your post did make me laugh so thanks for that.
