FWIW, Classic Audio Reproductions loudspeakers utilize TAD/Pioneer drivers.
I didn't know that, but they sounded quite good with Ralph's amps at RMAF. I didn't go there because of Springbok10's comment about his wife's distaste for the appearance of horns. For me horns come in all shapes and sizes so I don't really get the blanket rejection. The CAR speakers were gorgeous to my eyes and did sound great, as I said. The TAD Pioneers would still get my vote and $ were I to choose. But, for a huge-room filling sound I do agree that horns are an excellent recommendation and the CAR speakers were outstanding and may indeed to better at filling a huge room. The CAR speakers were playing in one of the largest rooms at the show (greater in volume than Springbok10's) and had no problems filling that room with lifelike sound. The TAD Pioneers were in a large room as well, but the volume of that room was significantly smaller as the ceilings were lower. Still, it was probably equal to the volume of the room Springbok10 is trying to fill. Those speakers just seemed to do everything right.
