The drivers in the 901's are only 0.9 ohms each X 9 = 8 ohms total (wired in series).
The Roomates take a 1.2 ohm driver and cannot be substituted since it has a built in amp.
It will work in the 101 but the original passive filter inside works in conjunction with a 1.2 ohm driver to create a 4 ohm total impedance, the tank filter provides a notch at 2.4Khz to eliminate harsh treble. This filter would have to be by-passed when using your replacement because it would result in a total impedance of ~ 11 ohms and the filter would shift the notch much lower in frequency.
The 802 uses eight 1 ohm drivers in series, but these could be wired in a different fashion to create either a 4 ohm total or 16 ohm total. If they don't change the wiring it would be 64 ohms and they would not make much sound at all. Same with the 901, it would be 72 ohms as there are 9 drivers total.
