I haven't fully comprehend what's the correlation of Fig. 2 and Fig. 3 related to Fig 4/5/6. 
paraline patent confusing figures

by examining the patent, there are modification in VTC implemention, on the red plywood sheet pictured below in yellow circle: (1) adding cones in front of bms throat, and (2) trapezoids on exit slot.

I think it's DIY doable.

Looks right to me. You've shown the path area increasing gradually as per a horn and this is right I think. But in the top part, the area is expanding as the wave goes out radially, so instead of imposing an exponental profile, you'd want to impose the correction to get from conical to exponential.
 
The bottom part is more complex, but similar issues apply.

Mykey,
That's it exactly but it is oval in plan to give you the slot form output. It makes sure that all points on the slot have the same signal path length from the original source. Its just a more compact way of doing what BMS do with their L.A. HF driver.

ArthurG,

what do you suggest about a good 15" to use with CP380M ?

Going back a bit I would just love to try some of danley/yorkvilles unity series

That did occur to me, but phase plugs are almost always centered on thediaphragm, thus providing equal pressure across the vibrating surface.

I was concerned that the throats on cone transducers in line arraysystems are often off centre, surely creating an area of much higherpressure at the edge of the cone. Does this not mean a) that breakupcan happen easier or b) that the radiated sound from one edge of thecone has to travel further to the throat than on the other?

I might be completely wrong here, just trying to clear it up in my head but can't find much conclusive evidence either way!

Cheers,

Chris.

"I was just unsure of the effects covering half of the driver with wood/metal would have on the sound!"
 
You mean like a compression driver where 90% of the diaphragm area is covered by the phase plug?

Riiiiight.

I'm well aware of the effects 1/2 wavelength coupling has on sound, I was just unsure of the effects covering half of the driver with wood/metal would have on the sound!


Thanks for clearing that up, it's appreciated :]

I would think it would have an effect on the lf frequnecy response, but the main reason for that is actually to keep the "sources" of sound less than 1/2 a wavelength from each other.  If the sound eminates from more than 1/2 a wavelength away (at the highest frequency the transducer is set to reproduce, since that is the smallest wavelength) then you can get phase cancellations and uneven frequency response across the listening area.  That is why so many line arrays use small mid drivers (4-6") rather than larger (10-12") drivers which can reproduce the frequencies just as well. The larger drivers when set next to each other will be too far apart for the frequencies they produce, to keep even coverage at the edges of the coverage area (of course it is hard to hear the difference with music, especially while standing in one point, but if you play pink noise and walk around, the difference is very obvious very quickly, as you will hear the "shape" of the noise changing as you walk!).  If you use larger drivers, you can make them "vent" out close together, so the sources of sound are close enough, you eliminate that problem!]]> Sat, 23 Aug 2008 03:14:36 +0000 http://forum.speakerplans.com/tom-danley-and-yorkville-offer-more_topic13807_post187314.html#187314
