I bought a Bose Acoustimass 15 speaker system 3 years ago and for the most time I've been quite happy with it (I know it's overpriced and doesn't have the best sound quality, but I used it mostly for movies and it fits quite well into my room). The problem is, that one month ago the bass-module broke and Bose wants about 230€ for the repair which I think is a lot (considered that I bought it for 1900€ and expected service), but the shop guy said it was cheap compared to what Bose generally charges for repair (both woofers of the bass-module are damaged but they would replace them for the price of one!!). Since there is a newer series which has more power than my old one I asked if I could buy a new bass-module, but I was told that Bose only sells the complete package and the cubes don't work with other subwoofer (the cubes are plugged into the bass-module and not into the receiver). The shop guy told me he was sorry that he couldn't offer any options and advised me to take the repair offer. I don't feel good paying 230€ for the repair (especially when I would face the same problem again, when it breaks the next time) but I think I would feel even worse loosing my complete system. I've been thinking about getting a better system because I've been using the speakers more for music than for movies lately (and I am aware of the limitations of the Bose speakers), so this is another point against repair. Now my main question: Is there really no way to use the cubes with any other subwoofer? I don't think there is a big market for cubes with broken base-module so selling seems not an option either. If I were to buy a new 5.1 speaker system (not Bose) how much would I have to spend to get one with equal/better quality than my original system?
