Just thought I'd comment on a pair I saw today while out thrifting. A six-sided cabinet with a bottom-mounted 12" down-firing woofer, and a 10" up-firing horn aimed at a pointed dome-shaped disperser mounted in the top. I passed for $20, but thought them interesting as they were the first pair of Magnavox omin-directional speakers I've seen, and also the first pair with a horn tweeter. Most of the pioneer models from the era had an array of standard tweeters. I've never been too crazy about omni-directional speakers.
