I like to show you a history review of my openbaffle projects.

my first open baffle speaker, operated with the miniDSP2x4HD, was built in 2018. It was a selfmade koax over 2x 10"Bassdriver Kenford HW1006
the Koax was made from a dy1026u and a Westra BT-52,

I cut out the whizzer from the dy1026u and mounted the westra tweeter in front of the 10"driver. The tweeter is passive filtered ba 3µF

It tooks a lot of filtersetting to make this work and it was a good learning prozess,

more pictures from the Koax building /german page

Next I build a modular openbaffle for testing a lot of tops
the bassdrivers are Kenford HW1206, with the miniDSP I use a Filter against the bafflestep at 40Hz/+5dB

first Saba

Blaupunkt suprakustik

The Sabas use a lot of digital filters to play well, the Blaupunkt use no digital filters! only against the bafflestep

RFT2159PB need a highshelf at 15kHz

Sica LP 208.38/426T without the whizzercone plus Westra BT-52, passive 4,7µF/6dB plus small DSP-correction

Part 2 wil follow

greetings, Hartmut
