Default Help with a rear loaded horn design?

Due to the too large size of the cubo 12's I have along with the monitors I have I want to compromise bass response a bit to reduce the overall size of my setup.

I want to ideally re use the drivers I used in the monitors I made they are Monacor SPH-210's. I have been doing a bit of playing on hornresp but I don't know whether I'm really getting anywhere. I want to do a rear loaded horn as the drivers will be responsible for covering frequencies up to 3KHz.

Max overall volume is 150L max.

This is what I've got so far:

I don't really even know if I have the parameters set right to model a rear loaded horn. The thing is I really have no idea where to start, whether these are suitable drivers, sizes flare rates and even how to get this all into an enclosure.

All help is good.

My limited understanding is that you want Vtc to be very large (like 3 liters or more depending on the driver), and you need a value for Atc as well.

There is no Vtc and Atc the volume behind the driver Vtc let we make it 5000= 5 liter. Play with it.
And Atc is your cone Sd.

Your S1 is bigger then your Sd. You could make it 1/3 of Sd and make the horn much smaller.
