I've been contemplating whether its worth buying dedicated foldback speakers. I currently use Electrovoice Sx300s or ZX3s for foldback - I bought these for their utility as an all-purpose box but I seldom if ever use them for anything other than foldback duty.
I have the opportunity to buy another pair of Zx3s for a fair price but I am wondering if its time to bite the bullet and go for some dedicated foldback speakers. The ZX3s are nice sounding boxes but their shape makes them awkward to pack in a small van.
What are your thoughts? What are the advantages? What is the best foldback for a small operator?
