#103 Polk Signature Elite ES50: $588 per pair Passive Estimated Amazon eBay
Smaller models: the Polk Signature Elite ES20 (rated 3.7/5), the Polk Signature Elite ES15 (rated 3.5/5) and the Polk Signature Elite ES10 (estimated 3.1/5).
Larger models: the Polk Signature Elite ES55 (ranked higher, estimated 4/5) and the Polk Signature Elite ES60 (ranked lower, rated 3.4/5).
Pros: Slim compact floorstanding tower in the Signature Elite series featuring dual 5.25-inch mica-reinforced woofers and a 1-inch Terylene high-res dome tweeter. Down-firing patented Power Port technology enhances laminar bass airflow and minimizes turbulent port noise, delivering clean extension down into the 40Hz range. Inherits the linear listening window and controlled dispersion demonstrated in Klippel NFS tests of the ES15 and ES60.
Cons: Rating estimated based on acoustic specifications and measured Signature Elite siblings (ES15, ES20, ES60). Dual 5.25-inch drivers provide less low-frequency displacement and punch than the larger ES55 and ES60 towers.
How it compares: Just above it: JBL Stage A180 - $106 more, 1Hz higher bass extension (-3dB). Just below it: MartinLogan Motion F10 - $1906 more, 3Hz higher bass extension (-3dB).
