Thinking about putting together a combo using Eden World Tour 800 and a Dr. Bass 12/6/+tweeter cab or 15" with the slot for the head. Some questions: 1. Choose NEO 12" or Standard? 2. Will there be enough air to cool the head? 3. Other choice is to go with a 15" - good idea? Music is classic rock and RnB/Soul. Want something versatile. Anyone tried this or a similar combination?
