Most importantly, this is your system, your ears, and your ducats. You do what is right for you.
Frankly, I hear the things you've said... I'm all for networking and getting a good deal... But what is that deal? That's where my little voice in the back of my head is screaming, "Nooooo!" I haven't heard a single person say Hsu is bunk.
Not.
Once.
For $1750 plus S&H, you can have 2 VTF15Hmk2 Subs of your very own, with low end response rated at 16Hz, +/- 2dB. Arguably, much better low end extension. We know, here, that it can perform with some of the better subs. Last I recall, it may have been responsible for getting Shady kicked off his Subwoofer Test Range... which means it not only performs low, but loud, too.
I'm not saying this is what you have to buy. Please don't misunderstand. I spent months shopping for Speakers and Subs. I'm just urging you to take the time to learn what you really need.
