This effort appears to be aimed at home audio, for a change, complete with built-in amps, more or less plug and play. This speaker will likely perform to PA specs, which is to say it will play loud without strain, although I am a little surprised he went 8" (vs. 10") for lower mids, ass-u-me-ing approximate X/O frequencies, with the two 15" for LF. I would take a road trip to hear these. Here's hoping the roll-out stays free of proprietary acronyms! Best regards, Paul S

With all my respect to Tom Danley to release a loudspeaker with onboard DSP and to claim the “highest quality of home audio in the industry” is kind of ridiculous. The people who know about digital as much as Tom Danley knows about loudspeaker feel that digital cannot filter/attenuate. So…   I do presume that this speaker will be the most accurate in the home audio, but it costs nowadays $40. It is how much a circuitry that does 64 equalization per octave cost. Unfortunately it has nothing to do with “highest quality”. "I wish I could score everything for horns." - Richard Wagner.

Yes, the sound reinforcement people, and most of the recording engineers, for that matter, have long since gone over to The Dark Side, using digital processing start to finish. They also mostly reinforce the "popular" music. It's the root idea of the speakers I find interesting, albeit there seems to be no good way to assess them except to try the interesting parts of the idea without the ancillary stuff that would most likely ruin Music. But this is how it is with PA drivers employed in home audio systems that are used to mine major classical works and performances, right? I'm currently ramping up a big project using "pro"/PA drivers, myself. No digital except CD/DAC source for me, of course. Paul S

The drivers are said to be 2@15", paper; 2@8", paper; 1@5", paper; 1@1", polyester. The X/Os are shown as 45Hz, 260Hz, and 2kHz. Does this mean that the 8" drivers are driven down to 45Hz; the 5" driver is driven down to 260Hz; the 1" polyester tweeter is run down to 2kHz?  I imagine this speaker will play well over 120 dB.  Can there be magic in the slopes that makes this easy for the drivers? Am I understanding this correctly, at all? Because it looks like those will be hard-working drivers! Paul S

This creates a physically phase aligned point source above 45 Hz and probably a bunch of diffraction. The double 15" woofers are an integral subwoofer. 2K would not be any strain for a 1" compression driver. Whenever I feel blue, I start breathing again.

Its being a compression driver likely means a 2" diaphragm, and it certainly opens the door for sub-2kHz performance. Actually, it's 8" drivers doing 45Hz that I find most puzzling. I have read and heard Danley's various explanations several times, having to do with wavelengths vs.  driver diameters, vs. the "point source" theories he espouses. Since the 2X 8" drivers phase out at 260Hz on top, I suppose they have pretty heavy cones and long excursions to make Fs, so it all works out on paper.  It's just that this sort of implementation runs counter to my experience, which makes it kind of fascinating to me, at least in the context of Danley's explanations. I would sure like to hear this stuff playing recordings I could take seriously. And, like Romy, based on personal experience, I find FR DSP hard to swallow. Best regards, Paul S
