Hello Clay,
I have owned the M&K V125 single 12" for a number of years. I recently had a problem with it and the audio store let me borrow the M&K MX-105 Dual 12" until it was repaired. WOW what a difference, the dual design is tighter and has considerably more volume than the single 12". The single 12" is an exceptional unit in itself BUT if i were going to invest in a sub i would DEFINATELY get the dual design. Hope this helps in your decision.
