Common questions
ANSWERED FROM THE DATAWhat receiver do you need to drive the Polk Audio Reserve R400?
The Polk Audio Reserve R400 is rated at 89 dB sensitivity (about average to drive) and dips to a stated 4.1Ω minimum — pick a receiver explicitly rated for 4Ω loads. Our free builder checks this against the exact parts in your build.
Computed from this product’s normalized, source-tracked fields — an unstated spec reads as “can’t check”, never as a yes or a no.
