I have some leftover subs/midranges that don't seem to have any datasheet available on the internet. I don't even know Fs and basic Thiele-Small parameters. Is there anything I can do with them?

Major studio build and about 3/4 done. These are my monitors a few days ago. Building crossovers tonight and coating the cabinets tomorrow. I hope to have them set up and cranked by Monday night.

Hi there,

Together with my professor, I've developed a multichannel audio system based on the AD1938 audio codec by Analog Devices and the BeagleBone Green (TI AM335X SoC).
The audio system offers 2 stereo inputs and 4 stereo outputs.
The whole project is based on open source software.
To demonstrate the possibilities of the audio system, I've created a surround delay effect with the open source C++ library DSPatch by Marcus Tomlinson.
Moreover I've created an automatic test based on GNU octave to evaluate the audio system characteristis, such as latency, THD+N, DNR, crosstalk and frequency-response.
The link to the full article is attached.
