Anyone here have these in their arsenal? There is a pair locally for sale. Each cabinet is missing one
driver. The cabinets are in very nice condition. I have some JBL drivers I can put in temporarily.
The boxes are made for specific drivers and especially since you already have one original
driver in each box you'd want to match those, either an exact model match or a match for as many of the numerous
driver parameters as possible. The SB528z is still a
current model, the "R" is the rental/touring version versus the "P" permanent install versions, so service parts including replacement drivers are probably available. Or maybe put both original drivers
in one box and have one fully functional box. Of course I'd be concerned about why they are each missing a
driver and whether the drivers in them are any good.
If you look at
http://www.eaw.com/docs/1_Current_Products/SB/Spec_Sheets/SB528zP_SPECS_revA.pdf you'll note that getting the specified performance or anything close to it requires processing. The recommended initial
processor settings can be found at

The $3,000 SoundBroker listing seems to actually be more than full retail price for new boxes, I find new ones apparently going for as low as $2,000 while eBay recently had a new pair of SB528zR listed for $3,675.
I recall one discussion on a forum where the general consensus seemed to be that they needed plenty of
power to perform their best and also that they could be used singly but worked best when used in multiples.
