The suspension is very stiff so the driver could be mounted cone down.
Qts on that driver is very low. Looks like it might be more suitable for higher-order designs.

15“ drivers just take up to much space for what i want to end up with. But you are right about that driver. It might give more output and cost less than a dual BMS solution.

My maximum height of the enclosure will not be more than 340mm. So even with 12“ units, its a tight fit.

it won't give a flat response in a ported box but efficiency (huge impedance peak) and maximum output will be very high for the size, the response is equalized in afterwards. Main downside is a lot of voltage swing is needed on the amp to get to max output (also its an expensive driver).

I am 100% comitted to dual 12“ bass reflex.
And i have just installed WinISD pro, so time to learn a bit about it.

But first i have a question.. what tuning frequency should i am for with the BMS 12n804? I want to have the best possible sound quality and flat response.
I Will be playing All kinds of music thrue them. Playback and live.

Keep in mind that i have never designed a enclosure before. So very much a newbie here

Use hornresp, traditional maximum output box is tuned to Fs.
