Converted exactly to 101.6 mm and 19.05 mm. The maker page lists amplifier ratings only, one for the woofer and two for the tweeters, so the counts agree. No per-driver power is stored. The maker lists a bass-reflex cabinet, so no passive radiator is stored.10Retailer pageldlc.com/en/product/PB00503434.htmlRead 20 October 2026Retailer: 2 angled tweeters and 1 woofer.
