Hi.
I'm planing a 3 X12" woofers per channel, dipole, and slot loaded - a la Nelson Pass, but way different.
My intention is that the combine slots opening area will be 30% of the total Sd.
I'm thinking to crossover them at 125Hz to 250Hz, perhaps 1st order. I'm just wondering, will this point - specifically the 250Hz - will be too high for slot loaded?

Symmetrical slot loading with no huge baffle between is nonsense. +1
Doesn't matter what percent of SD, identical and opposite simply cancels.
If you can tune the front and back phase shifts to be different enough,
then you might get a 6th order bandpass. That would not be nonsense.
Serious baffle (if you got room for one big enough) is also not nonsense.

And Nelson Pass's has huge baffles. Thnx. So open baffle designs nonsense to you as well? The front to back cancellation makes it a piston just moving in free air it seems. Been thinking about an H frame woofer. Some isolation of front and back waves from each other at least.
Hi,
Try quoting the thread on this forum where it is taken apart.
Otherwise just build something based on clueless nonsense.
rgds, sreten.
