Bass reflex plug

thingiverse

I have high-quality speakers in my compact bedroom (DK-SAT from Hifi-Selbstbau.de), but I had to position them too close to the wall, and as expected, they produced excessive bass. So, I created this plug to seal the bass reflex opening. Use rubber bands or cut a balloon into strips, just like I did, and insert it into place. If your speakers are similarly positioned near the wall, you'll likely experience improved reproduction of lower frequencies and potentially more details in the higher frequencies. Adjust the scale as needed; my original file is designed for bass reflex openings measuring 40mm to 47mm.
