About this driver

The Seas CA22RNY is a woofer with a free-air resonance of 34 Hz and a total Q (Qts) of 0.3. Its efficiency-bandwidth product (EBP) of 94 points toward either alignment. In a 18.0 L sealed box it reaches an F3 of 80.1 Hz (Qtc 0.707); a suggested 30.9 L box tuned to 46.0 Hz extends to about 51.4 Hz. See the sealed vs ported guide for how to choose.

modeled estimate

These tweeters could pair with the Seas CA22RNY 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.
