Any one measured what the frequency response is for Looney bins stacked side by side?

You shouldn't be setting your HPF any lower than 42-45Hz.

Thanks.

And for 4 it's closer to 38-40?

Will a pair play as low as 45Hz, at -3dB point?

According to hornresp i would say down to 43hz group of 4.
So with -3dB point @45hz your guess is pretty well, but for 4.
For a pair its not much higher.

I made the simulations with a void1000

keep in mind beyond the horncutoff the "horn loading" and so your "throw"
is becoming uneffective and your speaker works as a closed box,
but with a awful high xmax that destroys your speaker with enough power easily.

okay.

Thanks, I guess I will do some tests once they arrive. But that clears things up for now.

Thanks.
