Took a little while getting everything together, made etc. but now here they are. 115kg each in total weight. 4 parts..JBL, Yamaha and Coral.

Total weight of drivers 44.6kg compared to 24.6kg for the 4345. They work well. Can you guess the parts?

Thanks for that. Yep they're 2309 lens' on the 2310 horn.

Horn is 2309, lens-2310. I have a set of those too. What driver is behind them? How do they sound, ie: horizontal/vertical dispersion? How far from the speakers is your listening position? I'm curious as I have a plan to build an all JBL fully active system with 2245, 2206, 2390, and 2405. So it's the 2441 behind my 2309/2310s.
 
That's crazy, man.... Quite a room... What kind of lights are those (and candles?)? Hard to tell. Looks great though. I wish I had the space for something like that.

Of course, got them around the wrong way. I've got 2441's on them too which sound great. Listening position is about 3.5m from the speakers.

Cheers for that. Ive got a few different lights going on there. One's a mirror ball and the others mostly are globes that you can change colours with; great little investment for a rewarding effect. And a laser for the dance floor effect.
 
Are there felt pads between the plates? Quite often they get lost/fall out. If not, they should be re-installed to stop the plates from resonating; around 1" square each, 20 per lens, 10 per side.

Ah yes there are. I had never noticed that, thanks. All 40 are there. That lens should improve the sound for a room that size i'd imagine more that just the horn alone?
 
Well the purpose of the lens is to improve dispersion of frequencies above around 600hz. and it has been debated whether they are beneficial or not. I would try it with and without. But I just love the look of those 2310 lenses. Their usefulness will also depend on how far you sit from them.
