Add an L to tune to 33 and you will like the result.

33 is pretty low for an hdc3. He might not like it. I don't have the hdc, but for my 12s I tune about 5hz higher than normal and still get the sound I like.

Tune it lower, and maybe take away some of the in^2 of port.

Or tune to 27 //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif That is working well in my setup!
