B&w PM1

does anyone know if the new PM1 from B&W are time coherent designs? Is it a true 1s order crossover design?

The B&W PM1 speaker would appear to be time aligned thanks to the top mounted tweeter tube allowing the tweeter to be stepped back slightly from the planve of the bass/ mid cone. All B&W crossovers are stated to be of simple design to preserve the original signal, so it would be safe to assume 1st order crossover.
