Bookshelf-style home stereo speakers can really fool you when it comes to bass output, mainly because they are not designed for critical listening applications. That's why recording engineers and producers listen to projects through studio reference monitors or studio-grade headphones. The B2031A's long-throw 8.75" polypropylene-diaphragm woofer delivers smooth, deep bass all the way down to 50 Hz. Bass content that isn't exaggerated, as it can be in home speaker systems. Rock-solid bass that is an honest representation of the recorded sound, full of subtle nuance; the sound of fingers on the strings, or the rush of air through the long pipes of a cathedral organ, etc.
