The RS2 (reference sealed) has replaced the S2 which features all new, ultra low distortion and inductance drivers with improved sound quality and increased midbass.

So Audiholics measured and reviewed the sub already

I thought Ricci did the measurements for their subs

That's about what I expected. Can't wait for Josh to test the new Cap1400

Data-Bass tested 120v versions of the JTR powered subwoofers. We offer 240V amplifiers are well that can deliver a little more.

Comparing to the 18.0 is a little more fair as they are closer in box size and power per driver, although the 18.0 still costs more. Considering the S1 is said to be basically half the S2, so -5-6db across the board. Factoring that in the S1 and 18.0 look near equal 30hz down for long term output with the 18.0 having a clear advantage over 30hz, as it compares directly to the S2 40hz up. Burst output is very close across the board to the S1, each having a little more than the other in some areas, as well as distortion is comparable 30hz down. The advantage the 18.0 has is over 50hz where distortion and power compression are much lower, lower even than the S2 compared directly at similar outputs in that range.

I must be looking at a different product:

Get back to work. j/k

I'll probably have him redo this one. The dsp settings in that unit was a prototype and measurements do not look like the production units (smoother response, LF adj has more effect and limiter set higher). Burst measurements still ran with other, larger sealed subwoofers.
