I have a follow up question for this thread. I am looking to get a new sub for my system as well and have been looking at SVS, HSU and Axiom. I currently have full range towers (with dual nine inch drivers) in my room, but am looking for a sub to bolster the low end a bit. I would be using them for about 50/50 music and HT, but am very critical on both aspects. My main problem is that I am currently living in Germany, and cannot find anywhere to demo any of the above mentioned subs. I was looking at getting a Canton sub, to match the system that I have already, but I cannot get one with anything other than a 230v power supply, and I might have to move back to the states in a few years so I am hessitant to do that. I am lookings at things in the $500-$700 range so any input would be welcome. I had also considered the Outlaw LFE, but when I contacted them they said that HSU might be a better choice for me because they can use self switching power supplies. Any thoughts?
