Hi Thawach,
So I guess it was Tong Li in one of her early performances . Btw, I used the older MB series for years for mastering purposes. Keep on the good work!

Looks like you had no shortage of labor building the THA F horns!

Back in the mid 1980s I designed a cabinet very similar to your design, with two or four 15" per box, called the L2 and L4. Just ran the design through Hornresp to see what they actually could do with the power we had back then, it ran out of Xmax at about 245 watts per cone, which is about what the Crest 8001 amps could deliver.

The L4 tuning (about 45Hz) was lower than your box, but they kicked like crazy considering the low power and short Xmax (6.4mm) of the speakers used. We had 28 L4 cabinets, though the most we used at once was 20.

Be sure to use a HP just below your box tuning, or the speakers may develop some holes if you play anything loud and low .

You're welcome!

Use multiple drivers to increase Vas enough to calculate a decent size TH.
