Dual sub VTF-2 vs single VTF-3 = do you prioritize extra subsonic extension/output over MORE UNIFORM output that doesn't go as far under 20Hz? If you love big budget action/thriller movies that have tons of LFE and want to FEEL the bass as much as hear it, then the single VTF-3 (or VTF-15H for maximum subsonics) would be better.
1. 2. & 3. does describe me. However, I do like to feel the bass.
The "more uniform output" is what I need to quantify, which I know will be different for every room. This probably deserves a separate post on the subwoofer forum section, but I think I need to get an idea of typically how differently the response is seat to seat on a single subs vs. dual subs. Let's say if my MLP is the two inner seats on the two love couches and bass response is 100% at those seats, on the outer seats would the response be 90%? 80%? On the side couch, would the response be 70/80% of the MLP?
If the response is only around 80% of the MLP, then that's probably negligible to me. Since this will be my first serious set up I doubt my ears are nitpicky enough to be able to notice a huge difference from seat to seat.
Now if the response is say 50% of the MLP, that would be much more obvious and having two subs would probably outweigh the benefit of having the towers blend over more nicely.
I made a little chart based off the data on HSU's website comparing 2 VTF 2.5's to a single VTF 3.5. I added 3db to the single VTF 2.5 to represent having two. Interestingly enough, the duals beat out the single below 16Hz, but start to fall behind as the frequencies climb.
As Pyxle said, and I think I would agree, I don't think I would ever max out the volume of 2 VTF 2.5's (which have lower output that a single 3.5). Therefore I ultimately need to answer, what is more perceivable?
The improved blending of towers vs. bookshelfs we've been discussing, or the improved linear response of dual subwoofers? You guys have been very helpful. I feel like I'm getting closer to the bottom of this rabbit hole.
