Common questions
ANSWERED FROM THE DATAWhat receiver do you need to drive the Polk Audio Reserve R900?
The Polk Audio Reserve R900 is rated at 85.5 dB sensitivity (on the hungrier side, so amplifier headroom matters) and dips to a stated 4.2Ω minimum — pick a receiver explicitly rated for 4Ω loads. Our free builder checks this against the exact parts in your build.
How much do the Polk Audio Reserve R900 cost as a pair?
$599 for the left/right pair at today's tracked price. Retailers list some speakers per unit and some per pair without saying so loudly — we normalize every price on this site to what the pair actually costs.
Computed from this product’s normalized, source-tracked fields — an unstated spec reads as “can’t check”, never as a yes or a no.
