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.😀

Hi Xoc1,
Looking to use for PA applications from 35 up to about 90 Hz to get as much thump as I can out of 4 drivers so if OK will make four of 'em and hopefully make some eyes move 🙂
Cheers,
Andy

Hi Andy,
Wasn't sure, At first I simulated for home use, not for PA in particularly.
Here is an PA attempt:

Looks even better in terms of SPL, Frequency range and Impulse response....
Next step: get some box dimensions worked out, build a prototype.. Will let you know how it turns out!

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.
