Here is the print that I did.

It is important to realize that the plinth behind the speaker is a vital part of the design as it offers a high-mass energy soak that is critical to manage the energy re-distribution in the baffle.  Remember the bafflel is part of the transducer at midrange frequencies.  So here is the plinth missing from the previously posted plan.  It needs to be made of solid hardwood like the baffle.



Enjoy !

Any chance you can post the plan for the ZF15M too? With the plinth?
