About this driver

The Dayton Audio RS150T-8 is a 6″ woofer with a free-air resonance of 46.4 Hz and a total Q (Qts) of 0.37. Its efficiency-bandwidth product (EBP) of 99 points toward either alignment. In a 5.4 L sealed box it reaches an F3 of 88.7 Hz (Qtc 0.707); a suggested 10.8 L box tuned to 50.7 Hz extends to about 51.4 Hz. See the sealed vs ported guide for how to choose.

NOMINAL/manufacturer (Dayton spec sheet). Truncated frame (line-array/MTM). Fs 46.4 Hz; Vas 14.4 L; Sd 85 cm2; BL 5.7 Tm; Mms 8.3 g; sensitivity 87.9 dB (2.83V/1m); usable 47-4200 Hz; Xmax 4 mm; 40 W. Aluminum Reference cone (sharp metal breakup above passband; datasheet prints no breakup-peak Hz). Earlier seed (Fs 46, 86 dB, 80 W) was headline - corrected to datasheet.

modeled estimate

The tweeters below pair well with the Dayton Audio RS150T-8 in a two-way design — each grade is a modeled estimate of the crossover match, with a suggested crossover point. Open any pair in the guided builder to design the crossover and total the parts.

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