Well, I had a thread on here yesterday or the day before talking about the sub in my M&K 750 THX speaker package that didn't work. Well, they STILL don't have my V-1250THX sub in stock, but said they would ship me a V-125 TOMORROW. Well, since they seemed very comparable, I said ok because I ordered on the 18th of Nov. and I STILL don't have a sub. So, did I make a big mistake, or will I really not be able to tell much of a difference? I figure if I'm disappointed in the performance, I may sell this one to my mom when we build her theater at a discount and just buy an SVS. Thanks everyone!
