I would say not to overlook Realistic speakers. Some, like the Nova 6 on the smaller side and some, like the Nova 7Bs on the bigger are easily able to stay with the classic names of the late 60 and 70s. I know since I also own rebuilt and recapped units like the Advent Loudspeaker (now known as the OLA), KLH 6s with the woofers rebuilt with modern foam and probably my favorite, Marantz Imperial 6. The easiest to find and repair if needed are probably the Advents. It is hard to go wrong with any of the early Advents. My Nova 7Bs have incredible bass for their rather small cabinet.....I could easily live with them only.
