Short answer: the Brane X if bass depth matters most. It has the absolute deepest bass in this category, though boosted upper bass around 120Hz and a rolled-off treble leave it missing detail up top. The Harman Kardon Onyx Studio 5 answers with an elegant circular design and a carrying handle, but its own warm sound is also bass-boosted. The Harman Kardon Onyx Studio 5 is discontinued; its replacement is the Harman Kardon Onyx Studio 9.
Buy the Brane X ($549) for a large speaker; the Harman Kardon Onyx Studio 5 ($499.99) suits a boombox speaker instead.
