I haven't visited other places other than other rinks.
The one rink which uses the JBL 4520 scoops has nice sounding bass and what the cabinets cannot reproduce seem to be negated by how good what the cabinets can reproduce do sound.
I went to one rink in Atlanta that was using several old Electrovoice (I think) speakers which used some sort of aperiodic vented midrange which had the cleanest clearest sound I had ever heard in a skating rink, but the bass was lacking due to only using one dual 15" sub cabinet.
Another used two dual 15" ported JBL cabinets, but they either weren't set up right or didn't go much below 40Hz.
I think a lot of places don't try for the extremely deep bass because they either don't see a point or the necessary space isn't there or they don't want to spend what it will cost ETC...
