Members dboomer Posted August 18, 2004 Members Share Posted August 18, 2004 So Aged ... what is your rig? Re; ground splay ... Has anyone ever rigged a frame that would allow the array to be J arrayed but not so tall? Back in the day the Billy Graham folks used to carry these jungle gym frames and gimble mount all the speakers. I can't tell what Gary is shooting to but it seems pointless (from how I'm seeing it) to splay one speaker up. I was thinking a balcony or something. Gary ... what's up?

Members agedhorse Posted August 18, 2004 Author Members Share Posted August 18, 2004 My line array boxes are very similar to Gary's, except a 2-12" version with a more conventional CD horn array... about 60 degrees vertical but the summed pattern decreases with increased array length (as expected). I have flyware on my boxes too. I have one rig installed with 3 tops and 2 18's per side in a 1000 seat theatre and it works very well for everything but harder rock/punk/trash/metal. My other rig is 4 tops and 2 18's per side and I use it for similar applications. The thing I like about both Gary's and my boxes are that they are rectangular and stack nicely with "getto shims" and they are very light (by comparison).

There is a nice slope to the lawn we are pointing the upper speakers at. The difraction device is complements of the the lighting contractor.

This looks like an interesting solution, and possibly very good though maybe manufacturer specific with respect to the driver. I can't tell if other drivers could be used if there were sourcing or replacement parts difficulties. Link to comment Share on other sites More sharing options...
Members Steve_B Posted September 22, 2004 Members Share Posted September 22, 2004 This Beyma device looks a lot like the JBL horn used in the Vertec cabinets; slightly shorter if I remember correctly. The parallel sides and straight tapering top and bottom give a parabolic expansion profile that doesn Link to comment Share on other sites More sharing options...
Members agedhorse Posted September 22, 2004 Author Members Share Posted September 22, 2004 That's why it looked so interesting to me. I am a firm believer in the smaller line array cabinets. 12" and smaller is attractive. The biggest problem I see with 8" units is that there is a very limited availability of higher powered and efficient drivers that go down to below 80 Hz without getting into some serious non-linearities.

Members agedhorse Posted November 7, 2004 Author Members Share Posted November 7, 2004 Steve, Is that Beyma dirver/waveguide ment to be coupled to a horn or is it being used as a diffraction device? Link to comment Share on other sites More sharing options...
Members Steve_B Posted November 7, 2004 Members Share Posted November 7, 2004 I guess beyma could best answer that. I picked up on this particular unit because someone mentioned it earlier in this thread. My take is that it would be used in a similar configuration to the JBL Vertec system at the back of the V section. Another possibility would be coupling the device straight to the front baffle as Renkus Heinz has done with their PN series. This latter method certainly takes the diffraction effect to the extreme and was done by Vitavox years ago with their 4K horn. The big problem with sudden changes in cross section (as I Link to comment Share on other sites More sharing options...
