IMO A 60Hz attempt is too low and a 120Hz attempt too high. This is a difficult task, that of properly integrating horn loaded mid-bass with
D.R subs.

What type and slope crossover are you using ?
I'm hoping you are going active here ?

How much air can your sub woofer section move ?
You simply MUST be able to move prodigious amounts of air at the very low frequencies.

Keep in mind, that in order for these two to integrate, you must maintain a linear range of response, to at LEAST, an octave past either side of
the crossover point. And that, is almost impossible with a horn loaded mid-bass. The key word being "almost" but not impossible.

It's very difficult. To use, say, a 100Hz x-over point, your mid bass horn should reach an F3 somewhere close to 50Hz, and your subs should be linear
to 200Hz. Most subs BEG to rise in response as frequency ascends. Ideally, this is dealt with in the design, but a last ditch effort would be to add
EQ. after the crossover.

Yes, please do show pictures !
