DIY lovers often search some miraculous drivers for their loudspeaker projects.
In mine opinion, for the reference quality it’s hardly to find appropriate chassis on the commercial market (amateur (hifi, high end,..) loudspeaker drivers). With professional drivers in the other hand, we have often problems with synergy for High End audio applications. Do you ever think, that some profi driver manufacturers (like Eminence, Adam Hall, Renkus, …) produce some excellent parts for High End applications… I
n addition, do you sometimes modify some profi chassis? In mine opinion, it’s simply to modify some profi drivers for home extreme audio applications and made some cabinets far superior than with standard (commercial market) well-known drivers.
Maybe, the secret of the ultimate sound (High End loudspeakers) is in modifications of some drivers for profi applications or to find synergy between some profi and some amateur drivers.

Simply put professional drivers are optimised for levels totally
inappropriate for domestic use, and the best domestic drivers
are simply the best for the intended purpose.
(though some situations may require a number of drivers)
Do you think all the designers are idiots and lack your insight ?

sreten.there is one market were speakers have to be small to fit in the tower-shaped trendy enclosures, have to look expensive - and be not too expensive.
there is the other market were speakers are allowed to be as large as needed for optimal performance, look is not important but performance in the one or the other direction....
what drivers are used in the rushmore?
may i be allowed to suggest to read post#2 in thread "speaker companies" posted by Nelson Pass?
what drivers are these? home hifi market??

for me its low enough, and size is reasonable as i´m able to move them. And my kids are not able to knock them over.
An externally hosted image should be here but it was not working when we last tested it.
you sayd that ... (hehe !)
till said:
The rushmore is quite an interesting looking speaker. My guess on the drivers is: Raven R2 tweeter, PHL 6.5" mid (1160 maybe?), PHL 10" woofer (3430 maybe?), and an unknown 15" woofer (Polydax/Audax?)
The PHL drivers are just guesses based on the datasheet saying that they the bass unit is 97 dB/Watt efficient, and the rest are at least 98dB/Watt. They might even be custom made drivers, or from a different vendor.
It is quite an interesting combination, along with the active crossover setup. I would love to try an active 4-way system some day, and am considering doing an active 3-way system as a future project.
I had been considering doing a less efficient 3-way using the Raven R2, Seas M15CH001 and Focal 10W6411, while not pro drivers, look like an interesting collection of drivers.

Low wnough & reasonable cabinets
It's go low enough and it's in reasonable cabinets
I dont think all the manufacturers are idiots, but think the High End audio market is too commercial for that (our) kind of listeners

IIRC it was NP himself mentioning that that he uses a Raven tweeter and PHL drivers for the Rushmore.
Refering to PMC: I was able to listen to a fully active setup of their largest monitors at a recent meeting of the local AES section. Sound was very smooth, relaxed and clean (but imaging is definitely better with my Mangers) and a pleasure to listen to. The sound quality stayed the same when volume was turned up and one immediately had the feeling that it would stay that way at insane levels.
Regarding pro-drivers in general: Although most won't go very low (there are always some tricks one could try however) many of them offer veeeeery low THD at domestic listening levels. The JBL 2206 and 2226 for instance achieve 1 % THD around 110 dB. And they also use that fashionable glass-fiber/paper composite as used in some Scanspeak drivers, and it was JBL who used it first AFAIK.

man vs machine
In that kind of demo.... http://www.hiendfi.com/modules.php?name=Sections&op=viewarticle&artid=62
It is question if commercial or profi drivers are better choice.
Do you like hifi or live sound in your (our) homes?
Everything is an compromise, but.....
Home equipment known as High End are often too commercial for comparison into "live" sound

According to this:
http://www.diyaudio.com/forums/showthread.php?postid=110711#post110711
the Rushmore drivers, except tweetr, are from PHL.
Regarding HiFi vs Professional drivers: There isn't any speaker in the world that isn't a compromise (despite some high-gloss brochures). Both have their merits and downsides for Hifi applications. The real point-source with a frequency response from zero to infinity which is capable of SPLs >120 dB at all frequencies has not yet been invented. And it never will .......
One speaker that makes use of a professional coax driver (and which was quite impressive) is the following one:

frequency response
It's not matter of the frequency response.
Most of bas, mid or tweeter drivers can reproduced 2000 - 5000 Hz, but sound is different. If you have some driver with frequency response from 20 Hz - 20 kHz, it doesn't mean, that this driver sonds around 2500 Hz like (as good as) some tweeters on the same frequency.
Sound is the matter od system matching and depent on audio designer (not on drivers). But some profi drivers are better (and much more expensive) way to made ultimate performance system like High End audio cabinets (loudspeakers)
