I lean towards the Hsu system. I'm not a believer in 4" drivers, which is what JBL uses all around, and HSU, by virtue of being a purely Internet dealer with a heretofore fairly unknown name*, has a very liberal return policy.
Hsu counts on people not using that policy and, to do so, they cannot fall back on their name. They have to deliver the goods.
* but that's changed significantly in the past few years.
