Are tiny subwoofers worthwhile?


I have several systems set up, in both medium sized and small rooms. I'm wondering about some of the really tiny subs like Velodyne MiniVee 8 or 10. In principle they should be perfect for a small room, but, I've noticed that generally smaller subs seem to sound a lot less relaxed than larger ones. Certainly they go less deep, but that might be good in a small room where a large sub might overpower it. I guess the breakthrough in size comes from a combination of using a high power class D amp and a smaller driver, but how well does this work in practice?

Do any of you have experience trying out latest generation of high quality VERY small subs in small rooms (e.g. 10 x 12).

Thanks,

My room isn't especially small (22.5' x 24.5') but I am having good luck with a pair of small Hsu ST2 subs (10" drivers) filling out the bottoms of my Apogee Slant 6's. I measured them as flat down to 30 Hz which I consider adequate, and excellent in the "best bang for the buck" department.
I have a similar set up to Itball.
2 PSB subzero's (8"). For music it works very well once you have them dialed in.
2 subs helps avoid nulls.
