Good point Jamie - that was (I think) the last show I used them, and though I have them in my inventory I'm neither using or offering them for rental anymore because of my preference for the Danley's. The EAW's carried quite well up into the stands in that configuration, but as you can imagine, it was quite uncomfortable to be near them during the louder portions of the program. In a few weeks when my schedule calms down a bit the BH760's will go up for sale.

Serious? Ah well.  I love them.  They're the most muscial sub I've heard in a good while.

Nice!

Look into Robe lights if you plan to add more.

I came across this thread while searching for something else entirely.

Langston, I really like those towers!  However, even the smallest version is waaay to big for our needs.  Does anyone know if something like this can be built from standard truss parts?  I need about 3 metres of height and need to lift about 130kg of speakers.  (That translates to about 10 feet and 260lbs).  Any suggestions anyone?  Would it be safe?

Oh, Langston, by looking at those photos I'll agree with whoever it was (name escapes me) you helped out during the elections earlier this year:  I'd probably eat off your gear, too

Curious.  They are the worst I've heard.  A friend mixed on a rig with them and he concurred.

Kristian,

Something like this?



Find a local engineer and show him this L.A.M.Post thread:

He'll take it from there...

Nimrod, thank you for that!  I think I might really be onto something there

Those are some nice pictures, sometimes it pays to let others be the artistic photogs. On another note, I see you have the same roof as I do, as well as that size I have 2 other applied roof structures. I have never seen anyone do an "x" pattern on the guy wires. Curious to see why you do this. I always use a 30degree slope and use 2 wires at 90 degrees off the roof structure, not off the towers to hold er down. It looks like you just have the vertical towers guy'd. Can you elaborate this, and do you have any other pic's of this rigging?

Nice job by the way.

other than a lack of a strain relief on those NL8s, it looks like a pretty good gig

I feel a little funny about adding to a 2006 post, but that's a really good observation Trace.

Just for the record, James' observation that the loudspeaker cables need strain relief is spot on - I do that these days - 2006 was my first year in bidniz and I was even more clueless then than I am now.

Anyway, the roof system guy wire issue: I bought this Applied Electronics sloped roof from a guy named Jonathan Steitz that used to do most of Skillet's events as well as some other stuff. Great guy - really blessed me. I got the standard steel stakes that he used with a bunch of cable that I immediately threw away and ordered a bunch of nice stuff from Fehr and learned how to swage (verb?!). This was one of many, many things I've learned via PSW.

Then I started renting the roof and found that on occasion the promoters didn't want me pounding those stakes into the asphalt or surface du jour. I also found it a pain to deal with. After buying the Prolyte loudspeaker towers, I found that the Lakeland FL vendor was using huge water tanks to anchor their roofs down - they got them for free from some local orange grove farmers. Hope they asked permission...

But hundreds of gallons of water isn't all that pleasant or easy to acquire and dispense with afterwards, so...

I search the Net and saw something on the Prolyte site for one of their fancy roof structures that looked like the solution. It turned out that their engineers would respond to my emails with CAD output, loading recommendations, all kinds of wonderful stuff. Then it happened, a "duh, why the stink didn't I think of that?" moment:



Guy wire crosses on the sides and rear makes for a really strong structure. I've had my roof take short gust of about 60 mph with the skin fully raised without it moving. This happened about a month ago - didn't have time to lower it - the storm seemed to come out of nowhere and then things cleared up and we had one of the best concerts ever. Amazing result for a day that I thought was going to be tragic.

Obviously, if enough wind gets under the roof the whole thing will end up like Dorothy and Toto. But my study of roof mishaps pretty much leads me to think that stakes, water barrels, concrete highway barriers, etc. won't keep the roof up in high wind conditions either.

Two huge bonuses of my copy of the Prolyte scheme: (a) it's extremely quick and easy to do, and (b) the promoters routinely ask me what kind of holes or other damage I'm going to do with my roof on their football field or whatever, and I say "none". A perplexed look is followed by relief and then joy comes over their face.

There is no substitute for a good piece of glass on your camera.. It's kinda like how important a good speaker is

nice pics - nice setup
