I currently play through a B-15R, which is just a single 15" speaker. I am looking to change my set up eventually to include a mid-range and a tweeter. I also love the funk sound and I see that the Accugroove Bill Dickens model is a 2x12 and Dr. Bass has a model that they recommend for funk playing that is a 2x12 plus mid and tweet. I had always thought that you needed a 15" to reproduce the full boominess. I admit that I don't have as much knowledge or experience as a lot of guys on this board, but the question is why is the 2x12 recommended for funk?
