Yep, it's a turbo.
If you check my profile, the model # is in there.
I experimented with a Supertrapp tip for a while, but eventually went with the perforated cone insert in the tip to knock a few dB off.

great, appreciate the input LDub!, looking forward to checking it out later, need to get back to work
