Sure, will absolutely do it from now on!

Great to hear. So, to avoid ACTUALLY breaking your woofer, you should still add a high pass filter. :)

Okay so apparently the power amp just need a quick 5 minutes of rest to make it sing again ahaha! I'm so sorry for the fuss and being...

Fuse is still intact, and the unit still lights up. It just doesn't make any sound. So weird.

You're right! It does make sound! I did a quick sweep measurement, it is not damaged in any way! Omg! Yes this is the case now...

Try plugging the sub into your main speaker out to see if it makes sound. I suspect the plate amp may have given up. Best way to test is...

Check with an ohm meter whether the coil of the woofer in the sub is broken (disconnect it from the power amp first). If it reads a few...

Thanks for the info. Now I know my next sub should be a sealed design.

That is probably why you have a dead subwoofer, yes. The excursion of your woofer rises uncontrollably below your port tuning frequency...

Yes thats possibel portet subs usually not enjoy frequencys under the portfrequence.

Yes it is a ported sub. And no I didn't add any highpass filter. Was that a mistake? :(

For context, this is my living room setup: Khadas Tone Board -> iFi iTube2 preamp -> Naim NAP250 clone DIY amp -> GR Research X-LS...

It is a measurement artifact though. That test uses wide bandwidth so if you don't filter above 22.05 kHz as you are supposed to, all...

Here you go: Adding spectrum of the NOS mode 12kHz/48k sampled sine: And spectrum of the same signal but using OS mode: In case...

I have been fortunate enough to compare the Khadas Tone Board, Denafrips Ares II DAC, and Nagra R2R DAC ($35k) side by side installed in...
