BMS 4599 is used in my country from 660 hz onwards. The spl level is very high 123db as claimed. But in practice say you get 118db. But which low midrange driver to be used to match this.

I am more curious about what you would use as a HF above that one.

I would say something like 2 or 3 hornloaded high sensitivity 12" (like B&C 12PE32)

You don't need to match that numer, it is sensitivity, it does not tell how loud this could go but just the level you get with 1w input.
It is normal to have less sensitivity as you go lower but that is usually offset with more power capability, so you can push more power in the lower ways and reach same output level even if sensitivity is lower. |

This means i need more powerful speaker to get more output.
or need to use multiple horn loaded speakers as suggested by peter jan.

I would go for something like a dual PM60/PM90 LF section. But again, what you need above the BMS is much harder to fullfill imho.

I never knew such a thing existed! Looking at the frequency response graphs, it's seems that the sweet spot for the driver is around 600hz-4khz.

You could probably use one of those with 4x 12" and 4x 1.5" HF. With some clever space saving loading for the 12s, that could make for one helluva line array cab!

4599 presents two problems, 1. selecting the right horn ( some thing that can go down to 600 HZ ) and 2. getting a HF that can keep up with the 4599 all the way up to 16 K atleast. I have measured the 4599 using omni mic and I can say that the 4599 has nothing above 6/7 KHZ.
Finding a good compression driver that can do 6K to 16K at the SPL of the 4599, and getting both horns to work well with each other is a nightmare.
