That's basically what I'm doing to my woofers. Curently they are in the original baox from 1982 before most people knew about the T/S stuff or could calculate it if they did.

Mine will go in a Sonotube but facing sideways, and ported. They're modeling Flat to about 30 and down about 3 db at 26hz. I'm using a Linear Tech 250 watt per channel amp for them.

Busy remodeling the room on my weekend days that they go into at the moment. Doing the drywall now. Ugh!! hate Drywall!!
