A small speaker actually can put out a lot of bass, but generally it costs a lot of money. The DeCapo will reach ~35hz and so too will My Standmounts. Typically there is a limit to how loud you can play and postitioning is vital for both. My AN K well out into a room will lose a significant amount of bass as it requires a wall to re-inforce the bass. Not all speakers are like that. The De Capo wants to be a good 3 feet from a wall or you get a muddier sound. The expansiveness on classical music is amazing and it also excels with voices.

A big bass producing floorstander like the Studio 100 will be able to produce bass louder...IMO a little to uninvolving a sound for my taste, but a fine value.

You have not said which swans - But good luck and congrats on your new speakers.
