Cascade thermoacoustical interference

This is a tandem or cascade thermoacustical engine.
I used 2 similar test tube with my new heat exchangers.
The interference was so high volume!
Long time ago I had an experiment with this engine, but then I used the 2 tubes opposite for us. Wasn't interference.

The different is the not same far to the exit.
The engine doesn't stop when my hand close the tube, just the volume will be lower.

Thx for your watching!
