Hello Mike,
Two questions please:
I have just heard the rumor that ACI may be releasing some new subs based on the recent Servo technology.  Are you able to confirm this?  I have been seriously thinking about ordering another sub from you, but may wait for new ACI Servo products if you recommend it.
Also please Mike: For a music (not home theater) system, do you personally think the Servo approach in subs, produces a better audible result than your excellent tried-and-true sealed class AB (conventional) design?  I ask this because I absolutely love our Force XL, it is just outstanding.
