I used the W3 Tang Band drivers in Klipsch Promedia satellites. Pleasantly surprised that they sound better than originals. Well made little speakers. Since the voice coils are slightly larger, the crossover board had to be angled away by only using one mounting screw. Doesn't seem to be a problem. Mounting holes on drivers were tight fit but worked without enlarging. Very happy with these speakers. Money well spent.
