What loudspeaker design is this?

[Heavy-D]

Was wondering what the name of this design was and if anyone has heard this type of speaker before. Just for fun let's say it has 10"x2, 6½ mids x4 and 3 tweeters with the mids and tweeters in arrays. Frequency response 20Hz to 20kHz made as efficient as possible.

White Van Specials?

What I'm getting at is would this be a dipole array?

[Piotr]

It would simply be an array. You would need to make an open enclosure for it to bee a dipole... open back that is. The type of design in your picture is very common.

your sketch looks like something Nuance would have you believe normally sells for 5900 dollars, but since you've mentioned the magic word "loudspeaker", they will allow you a one-day-only opportunity to purchase them for 1999 a pair. You will not have the opportunity to compare them to another loudspeaker, but if you do, the deal goes back to 5900 dollars.

:rofl:

The speakers this sketch is based on are $15,000 a pair.

ooops, I guess I'm not current on Nuance's pricing. :righton:

Not Nuance and NOT going to pay $15,000 for speakers. lol

Well, the first thing that popped into my head was "bad" in reference to the design (name)

[joetama]

Put it all in a line with some crappy drivers and it looks like a old school PA speaker from the 70's.... HOME RIGS MANG!

[eb15]

Dipole simply depends on whether the back is open or sealed acoustically.

The radiation pattern of this "speaker drawing" you included would depend upon the drivers used and crossover type employed.

In the 1980s, Infinity had some home systems that were a a hybrid between a line source and a point source radiation pattern, by driver choice and crossover design. The RS-1b being a 4 box (stereo) unit with a separate woofer tower and a "winged" dipolish mid/tweeter array. The "one box" version being similar to your drawing except they used planar mid/tweeter drivers instead of your round ones. They probably did make one similar to your drawing, with domes/cone-midranges after I lost interest in their products. In this hybrid point/line-source the center tweeter is the point source and the other drivers, move toward a larger and larger line source as the frequency goes downward in the case of the RS-1b, limited to two woofers as your drawing in the "one box" design.

Some weird type of line-array?

[Tommythecat]

Two tens on the ass-end is not what I call "as efficient as possible" for 20hz extension, lol.

[Heavy-D]

I'm new to DIY and this is for learning. I saw these speakers from a company I won't name that looked good and won awards (CES) but didn't know what the generic name for the design was. In fact the sketch doesn't have the exact placement of the mids but it maybe close enough.

[JonMarsh]

You're just thinking of the Epiphany 12-12 speakers, which DO look a lot like an old Infinity model.




And they do some stuff more nearly resembling conventional line source arrays, too...



And just to show you can make relatively bad sounding expensive diople speakers, we present the smaller Gilmores...

Well, yeah, EVERYONE knows dioples sound absolutely HORRIBLE. :P

I don't see Ms. Oneil in that Gilmore pic so I don't like 'em.

[JonMarsh]

They tried to get a "munchkin" alternative model, because Ms. Oneil wouldn't pose with the these because they're too short and didn't sound so good... there are problems trying to do a short line array with inadequate driver area- probably something dictated by marketing...

[Dennis H]

Well, I see Gilmore has a new spokesmodel. He may be a good bass player but he just doesn't have the sex appeal of Ms. Oneil.

You guys can still ogle the photos at Linda O'Neil's website if you want.

As far as smokin' hot brunettes go I'm partial to Brooke Burke myself.

[AJINFLA]

Sweet. Rehash Carvers design. Get some scrumptious treat to ply your wares...
Hi-end audio at its finest :alol:

[Heavy-D]

These are the speakers I was talking about the RBH T-30LSE Tower Speakers.
What's the purpose of putting the mids around the tweeters?

[Davey]

There isn't any valid, technical reason to arrange the drivers in that manner. I think it's strictly aesthetics.

[gvinson]

Damn...I have never seen "Gilmore" speakers until now.....how short-sighted of me. ;x(

I am still trying to figure out what "Coherent, unlike other planar designs, the ribbon & woofer topologies are equivalent, resulting in exceptional coherency" is supposed to mean. Perhaps the girl can explain.
