About this driver

The Seas W22EX001 is a midrange with a free-air resonance of 25 Hz and a total Q (Qts) of 0.34. Its efficiency-bandwidth product (EBP) of 61 points toward either alignment. See the sealed vs ported guide for how to choose.

modeled estimate

These tweeters could pair with the Seas W22EX001 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.

Modeled estimate from T/S + geometry — no measurements. The verdict is robust; it improves with measured FRD/ZMA data.
