I'm thinking about getting one of those bad boys and selling my VTF-3 MK5s to help cover costs. It's unnecessary and frivolous, but I can do it without having to put it on a card or anything and won't need to sell the HSUs right away to cover it. I'd probably start by asking $1400 for both, leaving a little wiggle room to haggle down. I'd prolly take $1200.\n\nOkay, some of my thinking on this. I have both my current subs up front. The left side is hands down the best spot for a single sub in my room. No other spot I've tried comes close (and most of you guys know, I've done a lot of experimenting and measuring in my room). The one on the right measures like crap, and I've tried just about every other available spot in my room. I've even considered stacking the HSUs both on the left side. Enter the Monolith M-215... kinda the same idea in one box, and a decent boost in power too. The 215 is packing some heat with a 2000 watt amp compared to a combined 1200 watts with the HSUs.\n\nIs this just a plain stupid idea or...? If I just wanna scratch my itch should I say, get 2 Monolith 15s and stay with duals? The door isn't completely closed on the possibility of getting a 2nd 215 down the road, but that could be a while...\n\nOne other consideration, my HSUs are coming up on their 5th birthdays. Still going strong and nothing wrong with them, but my warranty's expiration is coming up pretty fast.
