I've got a VTF 15H MK2 and I've seriously considered getting a second but I'm just not sure how big of a difference it would make. Specifically, would it be a difference worth another $1,000+? What are your guy's thoughts?\n\nThis is one of those times I wished Hsu offered the free home trial with free shipping both ways like some of the other ID sub\/speaker companies offer. I would have had a second one here to try out as soon as I realized how much I liked the first one, which was pretty much immediately. :)\nAs you have probably read a thousand times on audio forums... it depends. I have a lot of space to pressurize (~5900^3), so I think duals is almost a necessity in my case.\n\n*Edit: Doesn't Hsu offer a 30 trial period?
