100-watts RMS 8s / $99 each from authorized dealer 200-watts RMS 10s / $115 each from authorized dealer Frequency range is ~80-5000 Hz on these -- the bottom end crossover point depends largely on how much power is ran to them. 8 ohm coils for large setups where you would be connecting 4 per channel to an SAX-125.2 or SAX-100.4 or 8 per channel on an SAX-200.4 These drivers are extremely light and relatively shallow so will fit in many locations easily and also will not weigh down doors with large quantities of drivers as bad as ferrite drivers. Standard Madisound grilles should fit them -- we will test it shortly.
