I bought a DSL20 combo last year, and immediately put a G12M in it. I love greenbacks, and its light years better than the stock 70/80. But it also accentuates the boxiness of the small MDF cabinet. I typically also use an extension cab with it, so that helps. I put the 70/80 in the ext cab cuz I didn’t have any other to put in it. Not great, but combined with the combo it sounds good. The other day I swapped the speakers back. The ext cab sounds absolutely beautiful with the greenback. I would like to replace the 70/80 in the amp with a greenbackish speaker with some better bottom to reduce the boxiness. It would be nice to not have to use the ext cab all the time. Will a creamback work? WGS ET65? Ideas? Opinions? Thanks.
