   Looking at the picture, I would say that's not 18pzb100 because of the 18tbx100 style cone. It's close to the old model from b&c 18tbx46 (looking at the alu frame), maybe it is an oem version of that.

	Ok found the pic i was on about. WMX is 4 ports, 2 internal, 2 external. WLX is 2 external ports only. Which I think makes these cabs quite different beasts. Looking at the WMX a bit closer, its beginning to remind me of the Nexo CD18 a little (obv without the cardiod rear driver) So.... WLX is a ported horn WMX is some weird horn/reflex/bandpass hybrid Looking at Jeff Nine Bars test vid on youtube though if the piece of paper test is anything to go by then the WMX shifts some serious air low down. As does the Nexo, but then the Nexo can't go that high without wallowing. Wonder if Jeff can cast some light on what they sound like in comparison to other cabs (X1 would be the obvious one that springs to mind)

	Are you sure the WMX has internal ports? I couldn't see any when I was looking through the ports into the rear chamber. The Martin website claims it's the same type of loading for both cabs and I've only ever seen ports to the outside on their cabs. Can you show us the picture?

	Sure, courtesy of TDA's photofiles: Unless there's something going on behind the baffle which boxes it all off and encloses the throat there's two triangular ports either side at the bottom - does that look similar to what you saw?

	I would say that like we were discussing ref. the WLX, there is a letterbox throat and those triangular cut-outs are just to include the otherwise wasted space in the rear chamber.

	they're not ports, they're there to use up watsed space to make the chamber bigger

	So how do one calculate the porting? Simply take the rear chamber as a reflex box or?

	Use Hornresp which can directly simulate this type of horn with ported rear chamber.
