Q How is the output of the full F1 stack (speaker over sub) compare to the Pro32 with Sub 2 in your experience
A
In my experience...
The first thing I did when I got my F1 Stacks (F1 Model 812 with F1 Subwoofer) was test outside in a free field (no walls), head-to-head with my L1 Model II with B2. One F1 system vs. one L1 system. Even though the F1 was much louder up close, at fifty feet and beyond, the L1 had caught up and the volume was about the same.

When I got my L1 Pro32 I compared it to the L1 Model II. They are similar in their performance in throw over distance, but the L1 Pro32 is considerably louder at every distance (about 6-7 dB SPL louder).

Now for the comparison.
The F1 Stack (F1 Model 812 with F1 Subwoofer) is slightly louder (3-4 dB SPL) than the L1 Pro32 with Sub2 at one meter. Now that's fully cranked, and I find it unbearable to run that loud.
BUT
The L1 Pro32 throw over distance is better because of the line array characteristics of the tower. If you start off with both running at maximum output (above), at fifty feet and beyond, the L1 Pro32 is louder than the F1 812. This difference is most noticeable above 200 Hz.
To be more realistic. If you run the systems side by side at 100 dB SPL, at fifty feet, the F1 would is around 75 dB SPL and the L1, about 84. For perspective, a difference of 10 dB is perceived as twice as loud.
What does this mean?
For maximum volume in front of the stage (the dance floor), you'll get more from the F1 Stack (F1 Model 812 with F1 Subwoofer). If you want to fill a large space with more even volume from front to back, the L1 Pro32 will be the better choice.
Also, note that to get similar horizontal coverage, it would take two F1 812s to match a single L1 Pro32.
