Summary:
Well all I can say is that this sub is night and day better than my old Servo 15a. Once I finally got it adjusted and balanced into my system this sub is amazing. There is no comparision on output, volume or the impact this sub has. All you servo 15 owners don't listen to this sub because once you do you be hooked. There were a couple of differences worth noting. This sub is great for music. But I would have to say that my old Servo blended in with my old Studio 100's better than the Signature blended in with my new S8's. It took more adjusting because the output of the signature sub is substantially more than my old servo and the positioning was much more sensitive in my current room layout. I had to really adjust the phase with the subs adjustment over my Anthem's adjustment.

So it is alot of trial and error to get it to blend in but once it does its amazing. All I can say is my neighbors felt the depth charges when I put U571.

My system:

Anthem AVM20
Anthem P2 amp
Anthem A5 amp
Paradigm Signature S8's
Paradigm Signature C3
Paradigm Signature ADP's
Paradigm Signature Servo
Sony DVP-9000ES with Dan Wright level III mods

Enough said.

Strengths:
Great improvement over original Servo 15.
Drop dead gorgeous finish.
Great impact and dynamics.
Just must be auditioned.

Weaknesses:
Your back trying to move it around your room. Very heavey.
