I fear TL's, probably becasue i do not understand them, Sealed is simple, ported a little harder and then bendpass but understanding the Maths behind a TL is very hard considering there is not programs like WinISD to help with design. I have always stayed away from TL in home and in the car...

Then again from my understanding a properly designed TL is something special, sorry i cant help you more :no:

Just build ported and sealed boxes
