Hey guy I’m getting some brand new MT121 tops! Was wondering what would be best to load them, from the diver to the horn? Thank

b&c 12ndl76 or bms 12n610 get the best reviews it seems! Compression driver-wise depends how much you wanna spend. I think lots of people use bms 4554 or similar

I suggest if budget allows I would go to a 3 inches with 1.4 throat driver, 4554 even if 1.4 throat is just a 1.75 comp.
In my experience with mt121 this allowed to lower the crossover and get more uniform dispersion.
Good horns could be 18sound xt1464 if you plan more a side, or rcf 950 horn for one cab a side.
Good cheap comps could be 18sound nd1460 or rcf 950, the 1.4 exit version.

Mating CD  to same manufacturer horn should help in get same exit angle and better performance.

These are heavy, consider also splitting mids and highs in two boxes. The CD box can be very light.

Just a quick note that I use a pair of the 18Sound ND1460 in my main PA, and find them excellent.

For years my mate used B&C DE85 with expensive B&C ME75 Horn.

Replaced DE85, with Beyma CP750TI on same horn, and was vast improvement.

Beyma CP750TI on PAudio PH4525 2" horn, was also very impressive, and with flattening eq,had perceivable  content above 15khz.

 The 4554's may only have a 1.75" diaphragm but one of those is more than capable of keeping up with a horn loaded 12, if crossed at 1.2khz one will provide more than enough spl above a pair of horn loaded 12's and sound sweet doing it. The 4550 1" is actually identical bar the throat size and sounds sweeter at high frequencies but at the cost of some mid range spl.

The 1.2khz is where that falls down for the mt121 though. Highest I can get my 12s is about 900.
