Mounting lights above speakers

[DJ Tony McQue]

I have a couple of Weddings over the summer that involve lugging my rig up numerous flights of stairs in buildings with very limited loading access. That being the case, I am looking to take seriously minimal rigs for these gigs (I didn't mean to make that rhyme). The plan is to mount 2 Datamoons above the speakers and a couple of Par Cans below. I have o rings for the cans but was wondering if something like this would be any use for mounting the Datamoons? :confused:

Has anyone used these? I can't for the life of me work out how they actually fix to the stands.. :bang:

I've used them many a time.

The Ultimax site (http://www.ultimax1.com/product.asp?numRecordPosition=3&P_ID=407&strPageHistory=cat&strKeywords=&SearchFor=&PT_ID=139) shows how they work.

Not at home, so can't dig out any of my rig pics at the moment.

EDIT

they slide onto the upright of your stand before you place your speaker onto it. The overhead splits, so you put the bottom half on, then the speaker, then the top half.

Judging on the example shown on ebay I think they look awful tbh.... I'd be interested to see if Adam's rig pictures look any better. :)

saw them at dj show north a few years back and they are a very ugly solution

I love cheap and ugly disco equipment, not to hire out but just for my own amusement. You can't beat the hiss from a vintage Tandy Realistic mixer. :)

Ahhhh...that was my first ever mixer, back in 1982.

Happy times!

Would they be man enough to take the weight of an EFX500?

Doubt it, I only used an Impossibled above a speaker, for a really small venue I used to do.

Still trying to dig out an image, can't find the external HDD they're on at the minute.

Do you have wooden speaker cabs? If so you could drill a 12mm hole in the top of each cabinet and fit some some T-nuts, then you could bolt a Datamoon to each speaker. I've used this method in the past to great effect...

If you use a sprung, shake proof washer on top of a flat washer there would be no need for one... :)

is there not a legal requirement for a second fixing? esp on speaker as you say they vibrate allot.

I think Mike has saved the day, yet again :D

Vibration will not cause a correctly fitted threaded bolt to loosen, it is sideways sliding of the nut or bolt head relative to the joint which is by far the most common cause. The sliding or slipping causes motion in the thread and loosening will then occur.

With a fixture hanging on a truss/bar there is a very high probability that sideways sliding will occur causing 'relative movement' within the thread of any load bearing fixings. In this situation it is obviously important to have a safety chain/bond.

However as the datamoon would not be hanging it's weight would be supported by downward force onto the speaker. The fixing would only be holding the fixture in position. In this case sideways sliding would be extremely unlikely to occur and a shake proof washer would suffice. :)
