Is this for HT or music...
I'd assume HT..... Have you had experience with the different SQ nature of a ported sub vs sealed or passive radiator.... ?
Some people like me have pref's.... Not a huge fan of a port contributing to the sonic nature of bass personally...
HT all the way. Not too much into music. I did own the LFM1-Plus and FV 12 in the past. They were very nice, but I just didnt care to look at either one of them.
I like the SC1's because they are small and compact. I heard one at my local hifi store and it was nice, but the room was very big per sq ft. It did do a nice job for its size.
I am interested in the HSU because it looks like a sub that I can play with and find it will be much more than I would need. So I have high expectations if I was to get that sub. The only flaw is SIZE. I think it would grow on me to look @ it for 22 hrs or so per week when watching movies, sports ect ect....
I am aware that this is a beast and HSU does makes a great product.
The only SVS I ever owned was the PB10nsd and I was expecting much more that what I got out of it. So I passed it on to a SvS fan, which honestly was no problem to pass off to the new buyer.
So back to the question, it looks like the HSU wins. I'll let you all know what I decide to do.
Cheers
