David12, the Wilsons are voiced by listening too. If you have them on the right gear they are quite musical, also very revealing. But put them on the wrong gear and they can sound the way you describe.
In speakers its really important to see what the designer is using for a reference, especially with regards to the amplifier. If they use a transistor amp don't expect the best sound with a tube amp, and vice versa. Tubes and transistors don't behave along the same rules, for example transistors can double power when you cut the impedance in half and no tube amp will do that. That can result in very different crossover designs, which may not work right if you don't have the right amp! They behave with different rules.
