I’m intrigued by this newish design from Bert D that appears to be a horn / SLOB hybrid. In particular I’d like to understand the arrangement in the throat area of the woofer array. Any body got any insight into the design?

Any links to more information.

The first FR box we built was Bert’s folded ML-Voigt.

Other than a photo on his homepage there is nothing on the website and googling doesn’t turn up anything useful.

Based on his previous designs he apparently just changed the single vertical phase splitter with multiple cones judging by the silver 'dots'.
