Have a wooden windshield on my terasse.
Converted it to an open baffle it's the first time I try open baffle.
Cheap car Hifi fullranges meant to radiate to both sides, half of them turned back.
With TDA 2003 in current drive mode sounds very good.
More than enough bass, turned 3db down at the preamp. Classy sound without boxy distortions.
I am impressed as the wooden corner horn type enclosure generates good bass. On the backside it's much less.
So an open baffle can profit from this horn effect.
Two types of fullranges used.
The ones with heavily structured cones what gives stability to the diaphragm sound great as these really go up to 20khz. The other ones have a heavy polyprop cone but sound nice in open baffle, too.

Amp got its enclosure from the back because its not air tight and would make bass reflex ineffective
Loudspeakers are not screwed to the stone.
Screws are difficult to fix and silicone dampens body vibration crossing from driver to the stone box.

This is just with a voltage driven amplifier. Its sound good - it has a more distortion than a current driven amplifier.
I will add a Whuzi Audio TP1 preamplifier which has Bluetooth 5.0.
The cheapo amp has bluetooth 2.0 and it connects only badly with my telephone. With the newer preamp it will be much easier to use it with bluetooth.
I could use a cable connection but some visitors would like to connect with their smartfones.

Added 2 ohms in line with the drivers to minimize distortion due to Esa Merilainens simple resistor method (website current drive dot info)
