KEF Q150 Bookshelf Speakers vs Polk Audio Signature Elite ES20

The KEF Q150 is the more distinctive speaker: its Uni-Q driver array puts the tweeter at the center of the woofer, which widens the sweet spot and gives a more three-dimensional image. The Polk ES20 is the bigger, more conventional box, with a 6.5-inch woofer and a Power Port that reaches lower in the bass. Owners and reviewers consistently praise the Q150's detail and imaging; the ES20 is the easier speaker to drive and the more forgiving of placement. Buy the KEF for music listening in a treated room, the Polk for movies and mixed use.

• Choose the KEF Q150 if you listen mostly to music and want pinpoint imaging and a wide sweet spot from a compact cabinet.
• Choose the Polk Audio ES20 if you want deeper bass and higher output for movies and games, and have room for a larger speaker.
