Hello everyone ! I am about to start build the following mid speaker from Fane,

which I want to x-over it at 180-200 Hz. So I would like to know if the choice of using

Fane Sovereign 12-300 drivers would work well. This is cabinet's supposed to be short throw

so I am not sure if I have to use drivers suitable for horn applications. Do you have any other suggestion ?

Thank you in advance !

P.S.1 I also keep in mind that I maybe customizing it to a vented enclosure by opening 2 or 4 small holes.

P.S.2 Sorry if this is already being answered somewhere else, I am new here and I couldn't find any similar posts

No point porting if you are going to xover that high.

I had a couple of those years ago - loaded with some Celestion, but can´t remember the model. Just try find something with a good midrange response & decent sensitivity. The Sovereign 12-300 should be fine.

What are your concerns there? This cab is designed to widen the coverage some from a standard flat baffle design, that it will do but only over a relatively narrow bandwidth.. from about 1khz up all output from a 12" driver is essentially a beam straight in front of it.

All your  'basic' front-loaded cabs suffer from that (bad pattern control) - but don´t have to be 'not that loud'. You can get a decent dB level as long as you go for drivers with good SPL at their designated frequency range.
