I got 2 cabinets each with 1 solo 15 inch speaker in them.They're pretty old/vintage speakers but have a great sound still.I need to know some opinions on what kind of head is best for 2 spakers like these.Gallien Krueger, Ampeg, Hartke,fender?orange is out of the question just doesn't do it for me,and markbass out of my price range ans much as I would really love one.
