Hello,  Just a little bit of feedback for you.  I've taken delivery today and if first impressions are anything to go by then I am very pleased indeed. The delivery was extremely quick and efficiently carried out with 'standard' delivery within 24 hours, most impressive.  The Alpine R-S65C speakers build quality is in another league, I already have the Alpine entry level speakers fitted but the type R stand out straight away as a quality package and I'm really looking forward to hearing them when I plan to install them with a inPhase IPA601 amplifier in March Many thanks and beat regards  Dave.
