The installation is pretty simple, but it is real work. You take out the 8 screws, remove the silver trim and carefully pull the driver out. Theres an adhesive tape near the supertweeter so go slow until it gives way. I ripped too hard in one place and tore my finish right off--fortunately the blemish is covered by the speaker/trim otherwise I'd be pretty upset with myself.
After that you put on new tape where the old was, re-attach the crimped on taps onto the drivers in the same positions as where they were on the oldies and button her back up.
You'll hear the promise of the new drivers immediately, but they won't be as engaging and will sound kinda constrained. At least that is the case in my system. I can hear things shaking lose after 12 hours of playing Isotek burn in tones though.
