Hi Beakybird: GREAT news ! Curious to hear how EZ or (difficult ) it is to swap out the speakers and what special tools are required. Is this basically a plug & play deal, or does it require soldering skills as well?

I'm really anxious to hear how the KP-100S works out on your gig today. In addition to the deeper bottom end, does the added 25 hz (sorry for that arithmetic error earlier) add depth & warmth to the mid range as well?

Do the new woofers affect the overall maximum volume of the unit at all?

Also,does the additional 5 lb weight make a substantial difference in ease of transport in/out of your gig-mobile?

Currently I take out the small Tyros subwoofer box (TRS-MS01) for added bass, so hoping the KP-100S woofer replacement will fullfill what the TRS-MS01 provides.

Larry, looking forward to getting a more detailed report from you soon, as it looks like I may be following your lead on this.
