Will this speaker fit a Bose 51 outdoor speaker?

It will fit physically, but the Bose original was a 4-ohm, instead of 1-ohm. If you have a pair, check the impedance of the other speaker. Both should be the same. I had to go to eBay to find a 4-ohm.

Is this the replacement speaker that will fit a 2002 cadillace escalade driver side door ?????

I'm not sure, I used it for my Bose 901 speakers..... Sorry

is the foam surround on these the new style that lasts longer and if so how many years is it good for?

The speaker works great, sounds as good as new to me. I expect the foam and the rest to last longer by keeping them dry and out of the winter weather. The environment makes the difference.

Works for Bose 901 replacement

Great sound. Great fit for replacement in my Bose 901s. Easy to install. I will purchase more as I continue to retrofit my classic speakers.

Good replace choice

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.

works with Bose roommate av

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.

Bose replacement speaker.

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 .

Replacement for a Bose Roommate II driver

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.
