Bass quality is dramatically impacted by the shape and size of the listening room along with the placement of the speakers in the room. That's because bass notes have a long wavelength -- the 42 Hz low bass note on a bass guitar is about 27' long. That's why sometimes one bass note will sound much louder than another. Square or cubical rooms tend to be worse on this point than rooms where the three dimensions (width, length & height) are all different.
For no cost, you can try moving the speakers around to different positions and see if you can get a bass quality more to your liking. Moving the speakers closer to the wall behind them will increase bass, as will moving them into corners. However, this may exacerbate room node problems.
You can also experiment with room treatment and bass traps to help even out the bass and reduce the room node effect.
The tradeoff is that a speaker position that helps improve bass quality may hurt the midrange or highs, or adversely impact stereo imaging or the soundstage. it can take a lot of experimentation to find out what works best for you, keeping in mind that this sometime gets kickback from your partner who may be more interested in interior design than sound quality. Some people even go so far as to bring in an acoustics professional to help with improve things.
The nice thing about a lot of the placement experimentation is that it's free.
