JL Audio Tower Clamps

[TC_2006_VLX]

So I sweet talked my boss into buying a 11 axis A22 thats gonna need some TLC. Part of that TLC includes the tower speakers. I thought all Axis Vandall came with with titan or WS tower speakers. Turns out I was wrong and this one has a pair of JL Audio speakers. That said they screwed/bolted them to the tower rather than using a clamp... see attached photos. My questions is obviously this isnt the best solution right? Does JL make clamps and are they stupid spendy like replacement WS ones are? Any recommendations on how to fix them on the tower?

That looks like an 8.8, which was not available in 2011, so I doubt it was OEM. Even if its a 7.7, I dont think they were an OEM option and ive never seen one threaded into the tower. Yes, JL does make clamps http://www.jlaudio.com/marine-audio-enclosed-systems-enclosed-speaker-systems-etxv3-etxv3-mounting-hardware or http://www.jlaudio.com/marine-audio-etx-enclosed-systems-mounting-hardware

Dang they want a pretty penny for those clamps... no wonder they cheaped out!
