Polk Audio PSW10 Subwoofer vs Rockville Rock Shaker 6.5" Subwoofer

The Polk PSW10 is the safer pick for most home theaters. Its 10-inch front-firing driver moves more air than the Rockville's 6.5-inch woofer, and Polk's long track record in budget subs gives it an edge in build confidence. The Rockville wins on paper specs and hookup flexibility: it claims deeper bass extension, higher power ratings, Bluetooth, high-level inputs and phase control. Owners of budget Polk subs generally report solid value with modest output, while Rockville's following is smaller and its power figures are peak-rated.

• Choose the Polk PSW10 if you want a proven 10-inch front-firing sub for a small-to-mid room theater and prefer a mainstream brand with wide service support.
• Choose the Rockville Rock Shaker 6.5 if you need high-level speaker inputs, Bluetooth, phase control or a compact wood cabinet for a 5.1 setup.
