Hi There,
Yep we are talking about the same products, however the Servo got handled by a discount chain called Richer Sounds over here, they are actualy the largest specialist retailer and they work out of tiny shops piled really high, but also tend to sell last years models at silly prices. Hence my Servo cost £400 me IIRC. Mirage is a rare beast here and very much a premium brand.

December 2001 £700

May 1999 Price £799
So over in the UK, they would have been quite cost comparitable, and when RS got them, a silly bargain.
I must admit, just putting the pair in the same room, the mirage looks less potent and it was only when i rigged it up to check it worked etc, that it really did suprise me. I guess to dual 8" cones do add up to a reasonable excursion and at a guess are substantialy quicker than a 15" one.
You explanation of why two mismatched subs would actualy reduce the sound is as ever simple and concise and i understand the logic. In some respects i also gather it could be an argument for not using even two matched subs, as room acoustics will invaiably mean that one is loaded differently and as such could cause a drop in overall levels.
I still like the idea of dual subs, i guess a pair of Servos are probably the way to aim for....I'd like to hear a BP400 as i guess that would be a better match for my system, but they are v. rare here.
Thanks,
Lee
