I have 2 drivers that I would like to use in a tapped horn and managed to come up with this design,

The driver parameters are as follows,

FS: 27.7Hz

Qms: 5.6

Vas: 33L

Cms: .22mm/N

Mms: 150g

Rms:4.6

Xmax: 23mm

Xmech: 32mm

Sd: 325sqcm

Vd p-p: 1.5L

Qes: .53

Le: .46mH

Z: 8ohm

Bl: 12Tm

Pe: 700W

Qts: .48

1WSPL: 83.3db

Im having trouble with the hump at 30hz, and have no idea of how to fold it, any tips?

My other question is regarding sensitivity. Is there any advantage in this design over a ported box?
