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.

Thanks for the helpful info, my system can be viewed by clicking system link by my name, my room is 14x22. I have PSB Silver-I and wanted a sub for 2 channel listening only as an alternative to upgrading to PSB Gold-I. As stated by others here I don't want to muck up sound with slow, boomy sounding sub.
I naturaly was looking at PSB powered subs which are quite affordable and discounted heavily on internet.

The bass from the Silvers is almost enough but needs a touch more extension and authority. I am looking seriously at 10 or 12 inch PSB powered sub which on paper gives equal or greater bass vs Gold-I, but was wondering about the difficulty in general of having seamless integration of sub with Silver so sound is not compromised.

If I get two subs then the cost is approaching the Gold-I, plus don't want all the clutter and connection hassle of two subs.......can the Silvers sound good with one PSB powered sub?
