Hi Andy
Did you have any particular application in mind?
Are you looking for bass extension for a home sub or efficiency for PA use.
I think that the 18" PD drivers are quite suitable for PA usage in a tapped horn, and used with a decent hi-pass filter should be able to take conciderable amounts of power before running out of x-max.
I haven't built any of the speakers that I have modelled up yet, but have a mate who has 8 off PD1850 drivers so its something that I am working on.:D

Hi Andy
Bjorno,s sim looks very good, but are you OK with the size of these speakers.
They will be the same sort of size as J Bells large tapped horns. Look at post 38 here:-

IE: OK for an install, but not really what most people would concider portable!
In fact if you substitute the PD186 parameters into Dons sim for the J Bell cab it works well. Probably would need a minor tweek to lengthen the baffle to suit the 18" driver.
