Do I need a subwoofer for desktop speakers?

Across community threads, most compact 3-inch to 4.5-inch desktop speakers roll off in the low bass, so reviewers note that bass-heavy listeners may want a subwoofer. The Logitech Z313 includes one out of the box, while monitors like the Yamaha HS4 and Edifier M60 are praised for clarity but flagged as light on deep bass. Several picks here (Audioengine A2+, Edifier QR65) offer a sub-out for later expansion.
