If you think you'd get more bass from a floor standing speaker,you are wrong..
If you need more bass, get a powered subwoofer. I suppose if there's no sub out, you can try to get a powered subwoofer with high level inputs/speaker level inputs.
Onkyo SKF-4800 is under your budget.
If you play music from CD's or play lossless files like FLAC or ALAC..Audition for yourselves.You may be pleased.
