SPL TD-1 (a la Danley SH46) mount options
josh allman:
So I'm looking to try flying these with a duratruss stand. That can get me in the neighborhood of 10ft plus stage height = 13.5ft over the crowd. I have had an adjustable plate made to get tilt from this horizontally, but wondering if there is a better way since this would go on a stand. I have access to a machine shop so anything can be made. Any suggestions?
My TD-1 boxes are installs, so they dont have any handles or sockets...I didn't get any fly hardware with them
Here's a pic of the auditorium we use. Only concerned about the center three sections, outsides are marked off.

I'm working on a similar project and will be following this with interest. I want to fly a single SH-46 horizontally (60 deg hor, 40 deg ver) with adjustable vertical angle. My current vision is to mount shear plates made from, say, .25 in. 6061-T6 on the ends of the speaker. Multiple holes in the plates allow a dead hang from a transverse beam at any of a number of angles. In addition, a U-shaped yoke (made from rectangular steel tubing) whose inside width is equal to the spacing of the plates would allow the use of a (beefy) tripod stand. Since the speaker is dead hung in the yoke the CG is always in line with the vertical axis of the stand -- the least tippy configuration. The plates need only to protrude 1 in. or so above the top of the speaker so should have little impact on transportability.
It will be a few weeks, at least, before I get to any of this and I'll post here how it goes.

I can have pretty much anything made so long as we have good direction. I'm guessing on my TD-1s, a lot of these recessed bolts are potential points for rigging hardware? I might go ahead and buy one of the Duratruss 3900Ls or something so I have something to test on.

There's a user on the danley-users-group on facebook (not a member here and I don't want to drop names in a public forum without consent) that has built u-brackets for just this application (single horizontally-oriented SH46). He attached plates top and bottom to attach the u-bracket, and then attached a pole adapter and rigging points so it can be flown or pole mounted. He also uses it when ground-stacking to "lift" the back end of the cabinet so it's not aimed upward. Pretty smart idea. I'll see if I can post some pictures.
Lifting the 118lb box plus hardware onto the stand in the first place would be the tricky part in my eyes, but no harder than ground-stacks of equal height. I wish I were strong enough to pull that off by myself, because I'm sure it would be a killer way to operate them.
