Re: Speaker wadding advice
The usual stuff (bad pun!) for transmission lines is long-fibre wool as championed by Dr Bailey himself.
You want the transmission line path to be low loss but slowed wave velocity... IE some suspended mass in the air, but little damping. Recycled wool fibres tend to be short and you can't get them stable at the low density needed. OK if you want total damping in a simple sealed or ported box.
Use anti-reflection material to line the walls of the transmission lines, but have the path of the line filled with low density fluffed-up long fibre wool.
I think Bailey had an article in Wireless World on it.
Chris Rogers explains transmission line stuffing in the notes for his PRO9TL design. Worth reading
Wilmslow or Falcon ought to supply the right stuff.
