I think I might buy or at least try out the 350v3 to compare the sound quality to the pb13. I wish I could lug this 155lb monster up there my neighbor and I struggled to get it out of the box. I would love to hear the 600, PB12-NSD or anything HSU has to offer. I went round and round about which sub(s)to get.

You maybe a little far for me to travel, Sirqack is closer though and he has the right subs to compare also.
