Well for me, The Next logical upgrade is a Dynacord.
I'm looking at $7000 fot the system of a Power Sub 315, a Sub 115 and 2 - D12-3.
I actually seen a DJ running this system today! I was amazed, my 1st thought was he must not be from out area, but you never know. He was doing Karaoke inside Macy's.
I hope to be in the position for such a system, in 3 years when I'm due for a system again. Financing with no credit check is #1 reason I went with a Bose system.
I am a Dual Personalty....Part Time Bose-O and also FBT and Fender Passport....For younger,Stronger Guys the Bose is "Little"....For me it is the Big System,when I want more than just "Two Speakers On Sticks".
