I hope an AKer gets these and posts a review. Sounds like they aren't much to listen to, but as large Ribbons (?) with a big woof-woof perhaps they could be decent with a bit of tweaking and the right system driving 'em? Maybe, more likely not... but only a good listening test will tell.
Sometimes odd or little-known speakers can surprise you. I have yet to see a second pair of Tardis "Sound Field Projectors" beyond the one pair that sold here last year, but they actually sounded very good. Judging from the size, weight, design/construction and the amount of solid wood, etc... used in them, they were probably too expensive new to have sold many or become common or well-known. Not quite the same thing as what is being sold here, but equally odd/unusual. Fun to find such things and/or to hear them!
