Srx725 center of gravity
« on: January 21, 2022, 10:10:52 PM »

Anyone have experience with flying these?  I just got a pair of the F version which has fly points.  Last season I was stuck using srx835 to fly, but the m10 points on top are so far forward that the pullback point had a surprisingly large amount of weight that it carried to angle the box downwards. 

The 725f seem to have top fly points more towards the center of the cabinet.  Anyone hang from those before?  Are they more of a parallel hang before using pull back?

Just curious - itíll be months before I get to actually try

Saw these flown a few years ago for a church.  The cabinets were inverted.  Appears they were using the fly points (couldn't see any detail due to no lights in the ceiling area where they were flown).

Hate to bring it up... have you checked the JBL website for any info on flying these.

Dave,

The SRX835 appears to only have three M10 on the top of the cabinet. Using only those three points, the rear top M10 would support 100% of the cabinet weight while still not introducing much down angle.

The 725f fly points appear to be at (or near) the COG (Center Of Gravity), the rear attachment pull-back point is beneath the input jacks on the bottom rear of the cabinet. Pulled back to where the cabinet face is parallel to the ground, the rear attachment pull-back point would carry less than 50% of the cabinet weight.

On the 722 (the 12" version of this cabinet), hanging from the points results in an essentially vertical speaker.  The pull back then gets used to adjust the angle.  The key is, you need a point where you can pull back to for it to work properly.  If you try and pull UP to get it to swing backwards, you end up putting way too much weight on the bottom support.  This creates a challenge if you're flying the speakers from a single point.

Agreed.  If you want to fly from a single point, APE rigging has kits for this that work amazing (for installations).
