These are exellent speakers and will pay at realistic volume levels without strain.
Also, they are much more efficient (but less flat) than more modern "box designs". This means amplifier hum and noise is more of a problem than with most modern speakers. Back in the old days, the most popular tube amplifiers were the Dynakits. Dyna st-70's (70 watt tube amps) are perfect for this application. Quicksilver currently makes tube amplifiers which are similar in performance, if you would like a trouble free current production amplifier.
The best thing you can do to make these old speakers sound new is to unplug, clean and reatttach all the non soldered clips and wire junctions from each driver and crossover and tighten all mounting hardware, being carefull not to break anything. I'm not kidding when I say "They don't make them like this anymore". These babies are full of hardware that can come loose over time. They good news is that they are easy to work on. Enjoy!
