Capacitor - Audiophiler, 400V, MKP Metallized Polypropylene

Question:
Hi - I’m interested in recapping the crossovers in a pair of 1980s Polk 5jr monitor series speakers. I’ve read that Sonicap 12uF are ideal, but those sell for over $23 each. How might these be different from those offered by your shop? Will a balanced pair be possible, or are they close enough that I won’t hear a difference anyway? Thanks!
