What speakers for 10k?

Just one more "for the record" comment:

A device does not have to be proven to work, nor convince any PHD panel of experts that it will work, in order to be granted a patent. The criteria are "novelty" (it must be something new) and "non-obviousness" (it has to be something that is not obvious). So I could apply for a patent on an underwater disco strobe as a shark repellant device, and might very well get it, regardless of whether or not it works.

Zd542,

My post was in response to this, posted by After_hrs, in reply to Onemanwolfpack's critique:

"The fact that you are blasting a patent (anyone can look it up) that was issued by a panel of PHD accredited experts in the field shows that you are not close to the expert you claim to be."

My point being, there was no panel of PHD experts evaluating the merits of the device in question. The granting of a patent is not evidence that a device does what it is claimed to do.

Regarding engineers, any piece of audio equipment that sounds good didn't get that way by being poorly engineered.

Marketing and engineering are very different disciplines. Marketing uses emotion(!!!) and engineering uses math (yawn). Anyway, it is quite possible for a speaker to be well engineered but then hyper-hyped by the marketing department. I recall a speaker whose claimed bass extension was an exaggeration by about one octave... but it was still a very well-designed, good-sounding speaker, despite the fantasy claims of the marketing department.

In order to impart directional control of sound waves, a device must be at least 1/4 wavelength long in the dimensions of interest. For example, the baffle step kicks in at the frequency where the edge of the enclosure is 1/4 wavelength away from the center of the woofer to either side, which means the baffle width is 1/2 wavelength. So a horn 2.5" deep will not have effective directional control below 1.3 kHz. Just wanted to put that in the record.

Unfortunately different yardsticks are used by different manufacturers for coming up with their efficiency and bass extension specs... but that would be another can of worms for another day.

Anyway a thread like this is a minefield for a manufacturer, and I've ventured in farther than is wise already.
