How to calculate cabinet dimensions when using two identical drivers in one cabinet

[RoboJ1M]

Hi,

I have three online calculators.

One is for calculating whether you should use ported or sealed.
Second is for a sealed cabinet
Third is for a ported cabinet.

The drivers I'm going to be experimenting are a pair of 3-way car 6x9 drivers.
They were free and available so that's what I'm going to be playing with.

I have the TS numbers for them from the manufacturer.

Singularly, they are equally suitable for sealed or ported according to the calculator.

However I want to make on single cabinet with both drivers in it wired to the L and R channel of the amplifier and the amp with take a mixed mono input.

Is there a way to combine the TS numbers together to treat the two drivers as a single driver and put those into the Second or Third calculator? Just add them or something?

Thanks,

J1M.

Hi, you just double cabinet volume for two drivers, rgds, sreten.

Hi, or simply double Vas in the driver model for two drivers, rgds, sreten.

Excellent, many thanks sreten

there is a small risk of damaging the drivers when sharing a doubled volume cabinet.
If one amplifier stops sending a signal, the other amp+driver sees the very big cabinet and you risk exceeding Xmax and Xlimit as well.

I will be driving it with a 2 channel amplifier with the input signal mono'd between the input to the amp's little box and the amplifier itself.
I'll be mono'ing it with this resistor network:
Why Not Wye?
Hopefully this will mean that is suitable unlikely to happen.
Many Thanks,

J.

A sealed partition between the two drivers is potentially less risky.
