This was a fun and challenging build!
Full gallery here.
I ordered some cheap single board amps and power supplies from AliExpress and used a DSP so each speaker (mid/tweet/sub) has their own dedicated amp and fine tune control ability for the frequency drop-offs, gain, etc.
They sound amazing!
Impressive and inspiring! Thanks for sharing.
My kid made some Bluetooth speakers at school in a technology workshop some days ago! They sound pretty bad. 😅 But it got me thinking how satisfying it must be to really take the time to build some nice speakers. That would be a step up in complexity from PC building for sure.
If he enjoys electronics and music, then I definitely recommend encouraging his journey into this direction! I would be okay with you asking questions in this thread if you need any help/guidance/resources.
I’m hoping we’ll get a DIYaudio in the Lemmy community. Your craftsmanship looks great!
Thanks! Yeah I always loved reading that sub for ideas and inspiration.
Wow that’s really cool! Out of curiosity, why did you make the sub cabinet so tall?
I made the sub use a transmission line for porting, which you can see in the full gallery.
This gives it a really low frequency response, but takes up a lot of room.
TIL all about transmission lines. Thanks OP!
Oh, gotcha. I don’t know the first thing about building/wiring audio, I just haven’t seen a sub with a cabinet that tall before! It looks great under the desk in your setup.
Sweet build but also, you have a fantastic kitchen
@roblarky I made my own TV sound bar with exciters. The challenge was getting the smart TV to give up audio signal to my “unauthorized device”, more than any difficulty making the sound bar produce audio.
Congratulations on your cool build! I keep drooling on these implementations and i hope I’ll muster the courage to build one for myself someday. Youtuber DIYPerks has posted a cool build https://www.youtube.com/watch?v=XEspOD1NHr0) very recently using 3D printing and plaster of paris that seems to have a great response. Another DIY youtuber ‘Tech Ingredients’ has some very innovative approach using exciters mounted on ceiling panels. https://www.youtube.com/watch?v=GslJ8Hf4WwE is just the latest of his videos in the series where he demonstrates the thing but the other videos in the same series are very informative.
I tried the exciters, it was neat…but not great sound fidelity. But still a fun little concept which definitely has uses.
I managed to make a set of panels sound pretty nice with some DSP, naturally, yeah there’s just too many modalities to deal with though they can be greatly reduced with tweaking exciter positioning, size, and corner radii. was a fun few weekends for me at least. Sounded good with jazz, very natural room filling sound. My best without DSP was always very shouty.
