Colin,
Funny you mention those drivers, I am working on making a budget component set using those drivers with a 2nd order crossover for 60.00 (i hope) depending on the assembly time.
Are you interested in teh crossover design? Measurements look promising and the off-axis response should be quite good as well.
They appear to measure better than some 250.00 component sets i have seen but the real proof will be upon using them in the car.
