All right, I read through EVERY reply on this thread, and as tempted as I am to ask "how much is this going to cost me?" to be like every other nood... I only have one real question. What is the count. I'm not sure if I'm in or not, I need to grab a couple more subs and I'm REALLY leaning this way, so I need to know where the count is on this. The next question does not effect my decision to buy (these are for a different install, I'm really debating between dual 2 and dual 4), but I need an answer just the same so I know what I'm getting into. How would this sub compare to a Stryke Audio AV12 Mark II? Both are TC sounds woofers, but I'm unclear as to what differences in motor structure etc. exist between these subs. Any info is appreciated!
