I'm having a new kitchen fitted, well the wife is, and my only requirement is a Sonos Connect Amp and suitable half decent in-ceiling speakers & subwoofer. This is just for the purpose of streaming music from a phone etc. I have a budget of £500-£800ish. For the speakers so far i've considered: Tannoy Mercury ic5 and ic6, KEF Ci130CR and Ci160CR, Bose 191, Q Install Qi65c. Are there any others I should consider? For the subwoofer the choice doesn't seem so great. There is a Cambridge Audio C200B but this is a bit pricey in terms of the overall budget. Also should there be a gadget in the equation to help/protect the Sonos with impedance matching or can it handle this itself? Finally should the subwoofer be mounted in the ceiling in a wooden backboard or even a box? Thank you.
