#86 Polk Signature Elite ES55: $898 per pair Passive Estimated Amazon eBay
Smaller models: the Polk Signature Elite ES50 (ranked lower, estimated 3.8/5), 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 model: the Polk Signature Elite ES60 (ranked lower, rated 3.4/5).
Pros: Mid-sized floorstanding tower in Polk’s Signature Elite range equipped with dual 6.5-inch Dynamic Balance woofers and a 1-inch Terylene dome tweeter. Offers higher sensitivity (90dB) and robust acoustic output capability with down-firing Power Port bass reflex tuning for clean extension down to 40Hz. Preserves the directivity matching and smooth off-axis tonal character validated by testing on the ES20 and ES60.
Cons: Rating estimated based on sibling laboratory measurements across the Signature Elite line. Substantial cabinet depth and footprint require generous boundary clearance from walls for optimum tonal balance.
How it compares: Just above it: Monolith Encore T6 - $351 more, 2.2Hz lower bass extension (-3dB). Just below it: MartinLogan Motion XT F200 - $5051 more, 2Hz higher bass extension (-3dB).
