- Two Sub1s or Sub2
Two Sub1s have approximately the same membrane surface area as the Sub2, (180 square inches).
The power difference is negligible (960 watts RMS compared to 1000 watts RMS).
Two Sub1s tightly coupled (stacked or side-by-side) should provide up to +6 dB[1] over a single Sub1 (118 + 6 = 124). The Sub 2 is 123 dB SPL. The difference is negligible.
The Sub1 goes down to 40 Hz. The Sub2 goes down to 37 Hz (-3 dB). The difference is due to the larger physical volume of the Sub2 enclosure. Running two Sub1s does not change the frequency response.
- ↑ +3 dB from doubling the power and +3 dB from mutual coupling.
