Focal make good speakers but they can be pricey. I'm in the same position as you at the moment and i'm looking at the Focal ISC 165 and the ISN 165 and ISS 165. The main problem i'm worried about is speaker depth as i want them to fit flush. I'll have to measure up the original tonight. The ISC look to be shallow enough, approx 50mm, and they're the cheaper option at £130 give or take. The ISN are a little more at £188 (cheapest i've found). Depth approx. 57mm You then have the ISS 165 which I have just found for £86! also at 50mm depth. It's looking like i'm going to go with the ISS 165, i'll let you know how i get on.
