Common questions
ANSWERED FROM THE DATAWhat receiver do you need to drive the PSB Alpha P3?
The PSB Alpha P3 is rated at 85 dB sensitivity (on the hungrier side, so amplifier headroom matters) and dips to a stated 4Ω 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 PSB Alpha P3 cost as a pair?
$349 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.
