Hi everyone!
I'm new to diyAudio and just getting into speaker building. I recently started my first big DIY speaker project because I wanted a good bluetooth speaker and figured I'd just build one myself.
For the main speaker, I’m using the Dayton TCP115-4 woofer and the ND25FW-4 tweeter. For the EQ and Crossover I'm using an ADAU1452 DSP. I also added a 128x128 OLED display with an ESP32 and a rotary encoder for controlling things like volume, source selection, bass boost, etc.
Since I like bass, I also built a wireless subwoofer using the GRS 8SW-4HE-8 driver. Both the main speaker and sub sound great, but I’m running into one big issue: port noise.
I was aware of chuffing as a problem before building and tried to keep air velocity below 20 m/s peak using WinISD, but in practice, especially on the sub, the ports are just too noisy. That’s why I signed up here, hoping to get some advice on where I may have gone wrong.
I’ll post more details about the sub in the subwoofer section soon. I'm looking forward to getting some advice on where I went wrong.
