I came across a pair of empty Electrovoice Baronet cabinets. H-22" W-14" D-13". These are corner designed cabinets. (not quite bookshelf size) Would originally have a EV 8" woofer and small horn tweeter. I loaded them with JBL 8" Full Range 16 ohm 1950's vintage. Was using them with a Heathkit SA-3 integrated, el84 - 3 watts per channel. Also have a pair of JBL LE8T 8" full range 8 ohm, which I had not tried.
I then used them with Wavelength 45 amplifiers. My point is that you have many options.
