Title: ZF15L speaker plans
Post by Steviewunda on 09/07/21 at 20:32:18

Hi all - I've searched but been unable to find plans for the Big Betsy ZF15L open baffle speakers - I'd be very grateful if anyone could provide a link.
Cheers
Steve

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 !

Thanks very much Steve! Building them will help distract me from the amp waiting list I just joined ;-)

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

Those are available on the ZF15M page, as a $20 download : )
