Well, those of you who followed my previous post- ISF or SVS have probably realized that the overall results have pushed me to get a sub first and ISF calibration down the line. Now my question is about the sub- Obviously, I’m still considering the smaller SVS 25-31 PCi. I even e-mailed SVS and Ron’s opinion was that the 25-31 PCi tuned down to 22Hz would be great for my small room- 10w x 15l x 8h. In all my research I’ve run across the HSU STF-2 which seems to be a great sub at a bargain price. Obviously the HSU has a 10” driver vs. the SVS 12” driver. My listening habits are 100% HT (have a separate 2 channel system) and rarely, if ever, do I listen at reference levels. I’ll be mating my new sub to an Energy Take 5.2 speaker system and replacing the 8” Energy Sub. Has anyone directly compared the SVS 25-31 PCi to the HSU STF-2 (or VTF-2, for that matter). What does one give up by going with the cheaper and smaller HSU? With my system and listening habits which would be the better option. I know that both SVS and HSU have fervent supporters and I don’t want this to be a pi$$ing contest thread. I just want to know if anyone has direct experience with both of these products and what their comparison impressions are. I’m still leaning toward SVS for future-proofing, but is the HSU in the same category? Thanks.
