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. **Q: This is for the whole speaker 9pc?** A: No. This is one of nine. **Q: Is this the replacement speaker that will fit a 2002 cadillace escalade driver side door ?????** A: I'm not sure, I used it for my Bose 901 speakers..... Sorry **Q: is the foam surround on these the new style that lasts longer and if so how many years is it good for?** A: 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fast delivery *by T***N on June 19, 2026* Sounds great.

No capacitors as on the originals though. Since they are 901 replacement speakers maybe the 901's have the caps ahead of all their drivers, idk. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/6458913-grs-rsb901-1-replacement-speaker-driver-for-bose-901-4](https://www.desertcart.no/products/6458913-grs-rsb901-1-replacement-speaker-driver-for-bose-901-4) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-17*
