About this driver
The Faital Pro 15HX500 is a woofer with a free-air resonance of 40 Hz and a total Q (Qts) of 0.28. Its efficiency-bandwidth product (EBP) of 138 points toward a ported alignment. See the sealed vs ported guide for how to choose.

modeled estimateThese tweeters could pair with the Faital Pro 15HX500 in a two-way design, but the seed Thiele/Small data is too thin to grade the match yet — add or measure T/S (Fs, Sd, Xmax) to compute a real compatibility grade. You can still open a pair in the guided builder.
