A friend just took a picture of my DIY speakers with my cat Pebbles sitting next to them. You can read more about the speakers here: {Spoiler German ahead} https://www.donhighend.de/?page_id=5022
I thought I would post it here for you to enjoy :-)
Yes both drivers (Tymphany SDS P-830656) are playing in the same bass-reflex chaimber. It's a 2.5 way design. Haven't thought about writing more as the link I've provided includes all the details about this build. It was my first diy build and I'm absolutely happy with the result!
They perform really well when listening to music in Stereo but lack a bit of bass when watching movies.
I ended up buying a 10“ subwoofer for movie nights which helps a lot. I mainly listen to metal and rock which does require fast and accurate bass which the speakers provide quite well. Thanks for the kind words. I really enjoyed building these and to be honest I’m already looking for something new to build 😅
