Going to be building 4 Pi speakers very soon. Starting to put my shopping list together.

Need to buy 1.0 mH 10A and 0.6 mH 5A inductors
Looking at Parts express I can get Air Core in either 18 ga (300W) or 14ga (800 W).

Q1)Would the 18 gauge be okay or is there problems using 14 gauge in terms of the wire gauge causing highs to be rolled off etc? Trying to correlate 300W with 5A.

Q2) Do I put any sound deadening material inside the "box" ie fibreglass on the back side only or on all sides except the front baffle?

Q3) If Q2) how thick, 4" fibreglass okay or is the special poly fills better.?

I am sure I will have many more questions as I really get into this. Time to get a sheet of MDF (good plywood hard to find and $$$) and get going.

Thanks for the help.!!!
