Mobile Streaming Box with Up2Stream 2.1

I have built myself a little 9L ported subwoofer box
with a random 6" subwoofer. (spoiler: this one died after the first rave^^)

I took two old flat-TV speakers for the upper frequencies.

looking quite nice so far…

structure painting…

delivery day…
Power supply is MeanWell LRS-150-24

bring into position…

voltage looks good…

grab some cables…

tuning…
the two little 2 ohm speakers were too loud and too much midrange…

optional battery pack - lasting for a long evening at moderate volume.

well ventilated…

very handy…

but the first mission at full volume for some hours didn’t end well - rattling sound from the sub…
opening this box was a pain in the a…

burn motherfucker… burn!

After new year party the tweeters smelled very toasted… but I was lucky to have another pair of the little smart tv speakers.

In ACP Workbench I raised the limit frequency for the tweeters to 1800 Hz hoping that they live longer now.

The difficult thing was to get more midrange out of the woofer instead. I tried it with a high shelv filter for the woofer at 700 Hz. I found no ohter way to set a better crossover frequency between sub and tweeter. Maybe someone knows?

Last but not least I decided to add nice grills to the membranes for protection.

Great work, thanks for the sharing. I dont’ have the clever hand to craft, but glad to see various projects. Have fun :slight_smile:
