Ivan Schellekens, before he ventured to make the more outländish designs that gave him a high end reputation, first had a line of more traditionally shaped speakers. These were under the company name of ' audio professional' and had types like AP-50 which I, being Belgian happen to have bought a pair of for a scrappish 25 euro. Best speakers I ever owned. They came along with a complete brochure with all the test results and have a super robust encasing separating the drivers internally and have the drivers set up in a tilted angle. If you ever come across any of his early designs, don't hesitate, although I can only really tell for the AP-50. They are way better then my IMF super compact's and my celestion ditton 33's but even in Belgium very rare.
