JBL M2 speaker system ....

Just installed in my living room and the M2 are sublime.  Had to run new elec. circuit with true 20 amp capacity to feed the Crowns and had to install the amps remotely to avoid fan noise.  If you research these speakers in depth you will find they are currently the best available at any cost.

I am intrigued 

jgandy,

Congratulations!

Did you have dealer support for the install and crossover programming? From what I understand, there are setup "features" that the consumer does not have full access to, only the dealer. Can you make full corrections on your own?

Thank you.

The program can be downloaded from the JBL Pro website onto a thumb drive and then directly into the Crowns.  This is a sort of  default program to make the speakers generally perform.  There is further programming that can be done thru a PC and other programming on line in which you can further tweak the speakers to your specific room.  All of this available to the owner directly without having to go thru a third party.  I have not done the further (room specific) tweaking since I am happy with the basic program and fear I might mess up a good thing.
