good bass
nice sound
They deliver great small room surround sound experience
they sound pretty good and offer a decent amount of power for small rooms
the bass is definitely very good
speakers can handle the bass fairly well
It sounded very clear and nice at all but
The midrange was strong and the treble was crisp throughout
well balanced and very impressive
It was very good with these speakers
