I saw these speakers pictured but not identified in the CES report. It's the fifth picture down:


I happen to have met one of the men behind this design and thought a little more info would be in order; something better than "That's not a siren on top..."

A Japanese high end mag MJ Audio Magazine picked up on these at CES and had a couple of nice pictures and this to say:

"An all-horn two-way system built by California's Cogent True-to-Life
Loudspeakers. The horns are fitted with massive DS-1448 low frequency
and DS-1428 mid-to-high frequency compression drivers. Unlike the
products of a certain German manufacturer that mates horns to direct
radiators, we are happy to see some serious driver units for a change."
