Cheers Wrighty, just what I wanted to hear. I assume you still needed to use the speaker ring adapters ? Did they make a big difference.. Only reason I was looking at the more expensive ones was I wanted as big an improvement in sound for the least amount of effort (just a speaker swap), I also notice they are slightly deeper than the SD's, was there much room left behind yours ?
Good advice on the amp though, they are less sensitive speakers.
EDIT : my mistake the HFs are actually 1mm less in depth, and slighly more sensitive than the SDs
