Well after one hell of alot of hassle with Richer sounds (which I won't even bother going into) my Servo 15 turned up today. Strange thing is I didn't know it was a ported subwoofer. Neither did they, until I told of them of the 3" hole in the side of it!!! I'm not joking, there were bits of sub casing all over my floor when I emptied the box....you can stick several fingers into the inside of the sub!!! So they're sending me another one, to arrive before 9.30am tomorrow Even though it's damaged I still hooked it up and WOW. Bugger me. I was sceptical of the hype over Servo subs, but I can safely say even with a hole in the side eek: ) it still blows away the 2 REL Storms I was running before. Clean tight bass, although I did notice a little distortion (probably due to the hole!)......even so it was less distortion than with my RELs. For anyone thinking about it, I STRONGLY recommend you try a servo sub. Be it Velodyne CHT, HGS (yeah I wish ) or Paradigm.......get yourself an audition now people!!!!!!! One other suggestion, REL subs are HIGHLY sought after on ebay. As many of you will know, I bought 2 Storms from THX for £600......one alone just went on ebay for £460!! Almost paid for my Servo 15! All I can say is....roll on tomorrow when I get a pristine Servo 15!
