PRODUCT INFO


THESE FIT THE BOSE SPEAKERS WITH WOOFERS USING THE 3 SIDED FRAMES. THEY ARE RATED AT 6 OHMS BUT THAT'S CLOSER TO THE "DCR" OF THESE. ACTUAL NOMINAL IMPEDANCE IS PROBABLY CLOSER TO 7 OR 8 OHM. FYI - these are not as heavy duty as the original bose units & do not handle as much power but are well worth the $. They do sound quite good & will be perfect if you are not always pushing your original cabinets to the limit. Also, the screw holes are in a slightly different position & some cabinets need the front edge of the hole in the cabinet shaved off a bit to get them to drop in completely but either is easily done

Here's info regarding the impedance of the drivers used in the various bose systems thanks to user: free2canoe

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.
