tapped horn isobaric drivers

[bubblersound]

Would a pair of drivers in an isobaric arrangement (cone to cone) work in a tapped horn? Assuming the throat area is large enough to accomodate the rear of one driver of course. Can this be modeled in Hornresponse by just adding the other driver in the driver arrangment window?

Hi

FYI,Here's an example showing an isobaric T-TQWT HR simulation I hesitated to post as the thread* starter seems to be gone?

Using Monacor IMG Stageline SP385-G as subwoofers for movies?

I'll guess that the 107dB/m is for 8W input power or ~98db/W/m when specified conventionally.

It also appears that @ ~35Hz the speakers run out of Xmax @ ~12W, giving about 109dB/m max SPL.

Can you improve on either the 98dB or the 109dB by going to dual/parallel rather than isobaric?

Right.

It also appears that @ ~35Hz the speakers run out of Xmax @ ~12W, giving about 109dB/m max SPL.

Right again.

Yes, but first, there is a question whether the box size is tolerable.
