What size subwoofer to get?


This question is for 2 channel stereo use 50/50 rock/classical music. I have floor standing speakers rated down to 35hz on axis and instead of getting expensive larger speaker want to look at adding "powered" subwoofer to slightly extend bass. Three models are available:
10" woofer 30hz
12" woofer 25hz
15" woofer 22hz
All these models have adjustable crossover frequency cut-off
50-150 as well as adjustable volume. What size is best to get, my concern is getting too much bass that is hard to dail back and becomes overwhelming. Or is it better to get largest subwoofer and not worry, volume control will be able to effectively tailor sound and control bass?

This is my first subwoofer so need some general advice from members who use them, thanks.

I purchased a Sunfire Super Junior several months ago to augement LFE when watching movies. It's been a bear of trial and error getting it dialed in and mated with my Magnepan MGIIIA's. It is switched out of the system for music listening. While you want the thing to produce low frequency information, you don't want it calling attention to itself. After months of different settings, I think I am getting it "almost there". My experience with it is as follows: The Sunfire subs have adjustment for gain, phase, and crossover. I currently have the sub in the corner, behind and about 4 feet left of the left speaker; crossover set at 100hz, phase set at normal, and, the gain turned all the way off -then bumped up "just a whisker". Again I only use it for movie LFE, but it produces the low frequency info from the soundtrack with ease, but isn't just boom and rumble. With these settings, I can't tell that the lows are coming from the left corner as I first could. YMMV.
