How do these "cylindrical radiators" work??

[intotubes]

Saw these on the Bose site. They look different, that's for sure.

I don't understand how they work tho...

From their 'brochure':

First, the sound level diminishes very slowly with distance, when compared to conventional speakers. It also sends sound in a very wide-angle pattern across the stage and throughout the audience. And it sends almost no sound up or down. Watch this video to see the distinct radiation pattern of this new kind of loudspeaker, dubbed the Cylindrical Radiator® loudspeaker.

I believe Bose has (re)invented the line array as only Bose can (probably using the same 3" 901 drivers for DC to gamma ray response!)

Now that is rich. You had to give them an idea.....now they will actually do it and make millions more on the inexpensive 3 inch drivers! I wish I owned the manufacturing company making those!

I think those drivers can be purchased for like $8 a piece...I saw them

listed somewhere once but alas I can't find them again (gotta love

losing all your bookmarks) []

Don't the 901's already have that kind of response? I thought bose was

looking into projecting sound faster than the speed of light so as to

eliminate all time delay (I'm hoping someone will catch the joke...)

The Nose (sic) 901 has an advertised nominal frame size of 4-1/2", the driver in the broomstick has a nominal 2-1/2" frame.

The woofer module for these uses a whopping 5-1/4" driver, and is 87dB/W.

It is said to go to 40hz, but no dB limit is mentioned.

What do you expect for $2K+?

[dragonfyr]

I suspect the primary use for these will be in designer churches and halls where the primary reenforcement will be for voice, most likely in a center mounted cluster.

[hooting_monkey]

Won't radiating it in all directions with sound bouncing off of every

wall in the area destroy any type of imaging, effectively making

everything sound mono-ish? But I guess you make more money when you

sell two or more bad speakers that effectivly sound like one bad one

than actually just selling one bad speaker. Those Bose researchers are

amazing!

[dragonfyr]

A line array features a dispersal pattern where the vertical plane is constrained and the horizontal plane broadened. Much like, for instance, a 120hor x 60vert degree horn.

Thus they are well suited for a central cluster where the reflections off the ceiling and floor are minimized.

[DrWho]

Besides, you want a single mono wide horizontal dispersion source when

you're doing voice - thus why a lot of the cool new churches are using

LCR arrays and fancy boards that support this (so the concept is that

music comes through the LR mains and then the preaching and all that

comes through the center mono cluster).

But I've never understood the concept of stereo for live sound....the

only people that will get any kind of imaging are those directly in the

middle - which is also a crappy place to sit thanks to the bass alley

(which is always there to some extent until you start getting into the

bigger fancier setups). The way I see it - a stereo PA sets you up so

that no two people will be hearing the same thing - but I guess in this

world of crappy sound guys this is a good thing because you're bound to

find a patch somewhere in the audience where it sounds decent...even if

it's half a mile away [][]
