It interests me that audiology always insists that human hearing is phase-indifferent, yet when it comes to transducer design it appears to matter - not just technically, but audibly.
Of course, as with all such equipment, everything should be designed to be as accurate as possible, but it does seem another area where what we can measure, and what we can hear, don’t necessarily overlap - but best design does still lead to best results…
Certainly very different to the rush for lowest possible THD a few decades ago vs. the terrible amplifiers that resulted!
I can’t see that Danley’s plot would have the same phase shift as the plot for the MEH above, that goes -180 to +180 on the same frequency, even with the same scale.
That’s the coherency everyone talks about.
What was really interesting was that when Pete was here he helped me with REW and we made further improvements in the phase plots, and we both heard the difference. Not small either.
Commented tongue in cheek, that some folk would spend £££££’s on an amp or speakers and hear less improvement😂
I’d previously used Holmimpulse with a less clean signal route into my DSP / DAC controller.
They were playing at Ascot for a bit. As you say, remarkable bass & extreme driver excursion. Better connection to the music than the big YG system that ran at the other end of the room
A nice rug would really tie the room together. I wonder what is in the room at the back? The open door must affect the acoustics. Critical listening required.
That’s holding up the roof. Slate speakers that size would cost much cash. The painting is a lifesize self portrait(ish) by an old friend. I left record shelves and amp in the pic to give a sense of scale. I tend to have a DIY frenzy about once a decade, then subside in recovery. A new cartridge just about does my hifi nerves in these days.
Horn-loaded dome tweeter, with a pair of accompanying horn-loaded midrange drivers. Bass handled by a quad of exceptionally linear, dual gap, 7" woofers in a sealed box.
