It was just availability of the speakers. I found the CS7.2 at a Burlingame, California dealer and had them crated and shipped to me here in Colorado some years ago. I had previously purchased an amplifier from that same dealer, so I was comfortable with the long distance transaction. I had also been considering the CS3.7, but never found an acceptable price when I was actively looking.
My wife and I have friends in Old Fort, NC and we occasionally drive our Sprinter camper van back east. Also have a brother in Marysville, TN (near Knoxville) that we visit as well. So I will definitely consider a listening visit on some future trip back east. Thanks for the future invitation.
I remain interested in an outboard XO upgrade. Although retired, upgrade cost is not really an issue, since I plan on keeping these speakers for the duration. My heirs will have to figure out how to move these heavy speakers and amplifier. (I have already coached my wife to contact TMR, which is local to us.)
