After reading all the comments I wish I could hear the difference in speakers more. Providing they are a quality unit in good working order I don't chase tone from speakers. I currently use a 12" Celestion V30 in an open back extension cab to marry with the stock 10" in my Boogie MarkV (I don't recall what is in that.) This setup sounds great to me and whatever I use I tends to sound like me. I rarely plug in at home so the sound live with the band is all that matters to me.
