I pulled my 2 ZLX12ps which have 4 gigs on them. All external screws (grill, feet, plate amp) were about 1/8 to 1/4 turn loose of snug. They are basically sheet metal screws in the plastic housing. The handle screws were tight. My driver screws were tight, but most of the internal horn mount and housing screws were 1/8 turn loose. Interesting tuning port design which I assume models OK but to my eyes seems like it could be an issue right next to the woofer.
That said, I still think they sound good. I think they are a little clearer than the passive version ELX which have been my monitors for the last 2 years and use the same drivers. I assume the differences are in relation to tweaks in the DSP. To my ear they are much better sounding than a JRX or anything else in the price range.
