Hello
Like so many others I got into DIY speaker building during lockdown and after being inspired by this forum and a few others I stumbled into the world of open baffle
My current system

3 x Full range drivers in a short line array with inductor on the bottom 2 to balance the rising response
The ever popular Alpha 15 in “H” frame
Bi amped with DSP crossover at 150hz
The enjoyment I get from these speakers is unlike anything I’ve experienced before, huge soundstage and exciting dynamics present the most lifelike image. I’ve discovered the joy of classical music as it swings effortlessly from a single instrument playing at about 70db and then swelling to 110db as the orchestra kicks in
Rock music can be played at 110db with no harshness and while you know it’s loud there is no rush to turn it down. (Only this loud for short demonstrations 😉)
The surface area of the midrange means cone movement is minute and the lack of distortion is gobsmacking
This is a crude frequency plot from the listening position using the IPad microphone

I really don’t know what the next project will be but I’ll keep searching the forum for ideas 😁
