Looked them up: they are kind of a tower arragement with two 12" woofers,a 5" mid-bass, a 5" mid and 2 EMIT type tweeters. Power requirements are 60-320 watts RMS. Produced in the 1980's. Cost in the range of $1500ea. at that time. Would be interesting to hear them A/B'd with Altec 19's in the same environment. Don't see any way the mids could be on the same level as the Altec's. Did not mean to start anything ugly, it's just that you don't often see a post saying something is better than the 19's. for regular living room use. But as the old saying goes: "One man's ceiling is another man's floor" and so forth.
