Greetings,

Does anyone have winISD graphs for HWK's- 12/15/18??
And the driver you are using?

Ray

You can only simulate if you're using one baffle, when using both baffles...what Adrian says!
One baffle used = 6th order bandpass

So, take one driver or an iso-baric configuration and calculate the volume of both chambers from the plan.
Make sure to calculate the volume that the driver(s) is(are) taking up.

Now comes the fun part change the resonance frequency until the port dimensions fit the ones on the plan.
I could do this for you, but where would the fun be in that for you?!?

btw, the outcome is the same for every driver, the box stays the same, the tuning stays the same.
But different drivers will give different sounds, because of there own characteristics.

Have fun!

From there on, you can change the resonances by changing the ports dimensions, the same way as above.

Cu plãcere, you're welcome !
