OMG these JBL 4722's are HUGE. How should they be wired?
First off, I bought these based on a few people's opinion on this site and let me say they are HUGE and very impressive in person. It's hard to explain how big they are until you stand next to one. I'm digging the look of them and feel good so far about making the purchase, but still a long way to go until I get them all working together. I'll wait until they are all wired up and running before deciding if they were worth the money.
Before I fire them off I wanted to double check the way I have it wired up. On the top it says to wire the "red & black to JBL 4739 Low Frequency Enclosure". I ran the red and black to the lower enclosure and plugged them in with the wires from the amp. So what is the little green "+ / -" on the box that is part of the horn?
I ordered the 4722N because the specs say "Available for Bi-amplified operation on (model 4722) or fully passive operation (model 4722N)". I can see that these are the 4722N's, but still not sure what the green +/- on the HF horn is?
I did fire one up with the wires (red / black) going right down to the bottom enclosure and HOLY EAR RINGING BATMAN! These sounds just like they look.... my ears are still ringing from leaning on the gain nob to fast. I only took them up to about half and my ears gave up.
Still curious what the heck is the little green "+ / -" on the box that is part of the horn?
Something didn't sound right. It was loud, but the sound wasn't right. Made the change and wired the amp to the green connector and the red / black wires to the lower enclosure and WOW! Now it's loud and the sound is PERFECT!
YOU THE MAN notnyt!

You have your amp hooked up to the enclosure, disconnect that, and run it to the phoenix connector on the crossover.
I will have an update shortly. Just finishing up everything and will have it all hooked up in a few weeks. I'm super excited!
I would love to read an update as well. I'm also curious which speakers you are going to use with these for your Atmos effects. I noticed another thread of yours and I also need xlr for my sub as a minimum.
Sorry for the delayed update. I've been wanting to get them turned on before responding again, but things have been busy and I want to make sure it has my full attention when I fire them up. I have not turned the system on yet, but it's all wired up and ready. Since I'm doing this all myself it took me a long time to finish trimming out the room. Right now I'm test fitting the 12" subs that go behind each seat and then finish up the bar so I can install the carpet. Here's some photos of where I'm at now (my wife is standing next to the speakers for perspective).
The 4722's are fantastic! They are unbelievably over the top and sound fantastic. I've only been able to turn the system up to about 35%. At that volume it feels like you're in an earthquake and the I don't want to break the window. Here's some photos of the theater room done (the last 2 photos show my garage and the theater is sitting suspended on that 3' tall glue-lam).
I also want to build my HT using JBL pro.
but with the smaller version - 3722N
as understand from your Thread - the N version is the version where i can just plug + and -
directly from the amp without need of Bi Amp or external crossover right?
Second Q- can i drive them with AVR ? in my case Yahama 3030
