Soundstage and explosive dynamics?

kosst_amojan, you are correct. In a 2 channel setup, you don’t want to call attention to any subwoofer, if you can hear them, you don’t have them setup correctly. They should blend in.
For more on subwoofer setup, check out Jim Smith’s articles on this subject. 

Some of the best speakers I have heard or that I would own have smaller woofers. For example, your Magico S5, Raidho d5, revel salon 2, and others have 8” and 9” woofers, and they have the cleanest and sufficient bass that you would want. Most of these speakers use 3 or more smaller woofers instead of 1 larger woofer.
