Yes, with quad SEAS 8's.
It sounds quite good, much better than the standard 15 in the vented LaScala cabinet. The bull-nosed horn was next, it has the same basic size as the Belle. I tried the Silver Flute 8's, but the SEAS work better.
With the SEAS raw room and EQ'd response, about 6dB of boost to make it to 27~28hz or so. The plenum depth dictates a 400hz HF crossover (BMS co-ax).
The dual 12 PPSL is for use with a sub, and to see how much bandwidth I can get.

OK, so the plenum depth null isn't solved by horn loading. 30-400hz is still an excellent range, as is 100-900.
With the dual 12" bulk size at 16 cubic foot at least two 15s could be added below 100hz, maybe even low eff high power high xmax subs.

It's much smaller than that, IIRC only about half that bulk.
