Nice! Which ones are they? In other words, are they ported or sealed? Also, what do the tweeters look like? Are they cone-tweeters (like they used on the original W70 and W70C), or are they the later purple-dome type that were used on the W70D and W70E models?
Also, what is the driver-configuration? Is it a 3-way or 4-way, and how big is the bottom woofer (12" or 15")? The answers to these questions should help me pinpoint exactly which version you have (and roughly how much power they can handle).
For best results (sonically), I would stick with amps/receivers made no later than the early '70's. Tubes or tubelike early-solid-state. I'm a big fan of the Sansui stuff from '69-'72 as well as their earlier all-tube models. Basically, you want a warm, inviting, musical sound. That's what will open those things up (They sound dead when powered by neutral-voiced amps... Trust me on this).
