Living in Alaska, they are a better "bargain" than the others. I have been quoted upwards of $500 to ship a sub to me from HSU and SVS of similar size and weight of the 600. I keep waiting for Axiom to dump the free shipping here, but they haven't yet, so I'll keep buying stuff from them till they do.... Looking forward to adding the two Vassalo 500's to my HT and seeing how well they play with the 600 this week.
