They give you some extra foam rings as well as plenty of glue. On line video instructions are spot on. Take your time working it and you will be fine. It took me about six hours over two days to complete the project. Speakers sound really good now. Way better than spending a couple hundred bucks on new speakers or having someone re-foam them for you. Review: Bose Repair. - Nice set and working well after the project! ## Features - 20 x made in USA foam surrounds: Outer diameter: 4.25" (108mm), Roll outer diameter: 3.875" (98mm), Cone diameter: 3.375" (86mm), Inner Diameter: 2.75" (70mm) Angle attach - 2 x MI-3035 rubber based repair adhesives 2 x applicator brushes - Easy to follow color illustrated instructions - The most common problem with speakers are rotted, torn or damaged surrounds. The surround is the outer suspension part of the cone. Constant vibration, time and the environment cause foam and rubber surrounds to degrade. Cloth and paper surrounds can become brittle. This causes distortion and poor performance. Luckily, our easy to install repair kits will make your old speakers sound just like new! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B009DNKQVS | | Antenna Location | For Bose 901 and 802 Speakers | | Audio Driver Type | Dynamic Driver | | Audio Output Mode | Mono | | Best Sellers Rank | #249 in Speaker Repair Products | | Brand | Simply Speakers | | Built-In Media | 20 foam surrounds, 2 applicator brushes, 2 MI-3035 rubber based repair adhesives, and easy-to-follow color illustrated instructions | | Compatible Devices | Television, Projector, Desktop, Laptop, Home Theater | | Compatible with Vehicle Type | Car | | Connectivity Protocol | RCA | | Connectivity Technology | RCA | | Control Method | Touch | | Customer Package Type | FFP | | Customer Reviews | 4.5 out of 5 stars 130 Reviews | | Enclosure Material | foam | | Is Waterproof | FALSE | | MP3 player | No | | Manufacturer | Simply Speakers | | Material | foam | | Model Name | FSK-4.5B | | Model Number | FSK-4.5B | | Mounting Type | Flush Mount | | Number of Audio Channels | 5.1 | | Number of Items | 20 | | Power Source | Battery Powered | | Speaker Size | 3.38 Inches | | Speaker Type | Bose 901 and 802 Foam Speakers | | Specific Uses For Product | Bose 901 and 802 speakers repair | | Subwoofer Connectivity Technology | Wired | | Subwoofer Diameter | 4.25 Inches | | UPC | 700621981381 | | Unit Count | 20.0 Count | | Warranty Type | Limited | | Water Resistance Level | Not Water Resistant | | Wireless Technology | No Wireless Communication Technology | | Woofer Diameter | 9.14 Centimeters | ## Product Details - **Audio Output Mode:** Mono - **Brand:** Simply Speakers - **Connectivity Technology:** RCA - **Material:** foam - **Mounting Type:** Flush Mount ## Images ![Bose 901, Bose 802 Foam Speaker Repair Kit FSK-4.5B (20-Pack) - Image 1](https://m.media-amazon.com/images/I/71x9rK1jexL.jpg) ## Questions & Answers **Q: Will this work on the series 2's?** A: Series 2 Bose 901s had cloth surrounds that shouldn’t need replacing.
