GRS RSB901-1 Replacement Speaker Driver for Bose 901 4-1/2" 1 Ohm

Replaced the speaker in my Bose Freeespace 51 outdoor speaker. it was almost identical and works tremendous. sounds like new. deep bass and clear treble

One of my 20 year old Bose Roommate II speaker drivers stopped working. This is a perfect, drop-in replacement for it. Sounds exactly the same as the original.

I used these to repair a set of Bose roommate av shielded speakers. A perfect fit except for the shields; I decided that the shielding wasn't worth tapping a new screw hole in the center of the speaker magnet, so left them out. The speakers are as good as new, and a few pounds lighter as well.

Lack of quantity

Works almost as good as new. It fits the older Bose 901 outdoor speaker enclosure. This speaker is not rated for outdoor use but otherwise it works great.

This speaker fits my Bose outdoor speaker that had stopped working. Saved me from sending it back to Bose to have them fix it. Took all of five mins to replace the bad speaker. Works great .

I bought these speakers in 1983. I decided to replace the speakers and boy am i glad i did. i love these replacements

great speaker - exactly what I was looking for …
