Hi,
 
In march 1995 Selenium delivered this plans designed for their wpu1805 driver: 
 
 
Notice that it's anechoic chamber measurement.
 
Plans in millimeters:
 
 
To me a 1850 is far better.
 
Regards,

They work well but the 1502 outperform them a lot! We have built both of them...We have 8 of the 1502 and 2 of the 1805. In stack of 4, the 1502 kick and go very low...We use all RCF drivers inside, they give lot more output compare to the original Selenium drivers. We built them on the other way to couple the mouth..
