Adding passive tube, keep the same, or different?

[gbaby]

I have the BTA10250D and I'm adding a second passive tube. Anyone with any experience in adding an 8 inch passive to the existing 10? I'm trying to figure out if that may give me better sound range than just going with two 10's, or if it can even be done. Thoughts?

The correct and recommended slave unit for the BTA10250D is the BT1014. Best results will always be achieved when using the proper sized slave unit as the frequency response and efficiency of both Tubes will be the same.
