Love these guys... If you do anything big/ Hip hop etc, you need a sub... But great speakers... Love them...
Way way better than Eons in my opionon... NX750s are the 15" driver model, heavier but they have a good amount of bass...
Again, The 55Ps are great, i run them for schools,(k - 6) a sweet 16, 50 -75 kids.
They have great head room, Max SPL is huge on these, I only one ever ran them too far, bar gig I did, College night, place was packed - 300 or so... hip hop, rap... Couldnt take it all....
Honestly, Highly recommended, feel free to direct any question my way.
