The regular range no longer lists that model, and that driver appears neither in any monitor or floorstander in the range. The CAM and SAM are each using a 6.5in full-range driver with whizzer cones. To move to a larger transducer, Louis is apparently placing a second 3.1 (4.5 in. cone) or 6.5 in. driver with a LF cutoff at 200Hz for a low-frequency-only driver while the other speaker remains full-range, calling these "1.5-way speakers." There is no crossover. The floorstanders have two 8-inch driver models, one with 2 speaker cones and a second pair of models with one or two of the 3i cones..
You might email Louis to ask about the 7. He does special designs as an OEM manufacturer (a 2.1 speaker system for Symbol Audio's $30K console, for example)
