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 estimateThese 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.
