  • I made couple of bass tramps tuned to the room’s main resonant frequencies, which I measured. I followed instructions from the book.

    I added sound absorber panels to the walls and ceiling to kill immediate reflections from the main speakers plus a sprinkling of additional panels to kill reflections and also act as decoration. I also needed to move one radiator because it was in the worst possible location for my setup.

    The room got thick curtains to improve absorption, and they also darken the room as it is dual use music listening and home cinema room. A few defraction elements went into the ceiling for a good measure. The ceiling is made of custom panels that I made myself from wood and fabric to allow sound energy through to the various acoustic elements behind them.

    I also spent a fair amount of time with subwoofer placement, but in the end it became a bit of a compromise between sound and placement of furniture. Nothing a bit of signal processing can’t deal with, mind.



  • Here are the main components of my system, which has become a bit of a collection over the years:

    • Home Assistant on RPi
    • zwave USB stick
    • a number of lights, switches and multi sensors on the zwave network
    • A cluster of four RPis for various scheduled and transient tasks (data ETL, solar energy forecast model training and forecast generation, house battery and EV charge planning and execution, scraping and processing council bin collection schedule)
    • two RPis handling motorised curtains and cooling fans in home cinema
    • three ESP2866s running ESPHome controlling relays for switching sauna, floor heating and water immersion heating on/off
    • ten ESP32s running WLED controlling LED strips inside and out
