I am considering a speaker set up in the $1000-$1500 range. There are many package deals and manufacturers that target this price-point but most of them don't seem to come with very good subs. So, I was thinking of getting a seperate sub, in particular I was looking at the HSU-VTF2. I hadn't considered SVS before because they are a bit pricey for my budget but I see that the new 25-31PCi can be had for $550 vs. $500 for the HSU. So, does anyone have any thoughts on how these two subs would compare with one another? BTW is there a hallmark for how much of my speaker budget should go towards a sub? Am I buying too much sub compared to the quality of speakers I am looking at in this price range? Also, I'll be moving to a smallish apartment in the near future, if I can't crank my sub very loud should I be looking for a more modest solution anyway? Thanks.
