Well I agree with Geoff and think your strategy is a bit 'odd' but it's your money. But I would add that actually Hsu VTF-2 is very capable to put out a lot of SPL enough to wake up your neighbor. Off course VTF-3 will give you more SPL. Based on mfg recommendation, VTF-2 is for 3000 cuft or smaller but I feel this is too conservative unless you are a bass freak. Good luck on your choice.
