I'm coming over to the US on Boxing Day & won't have the chance to try out any heads. I've came down to these two due to the features & price. I'm after a couple of different types of sounds... A deep, reggae bass sound & of course, a slap-bass sound. Anyone with any experience of the two heads please feel free to chime in. All opinions appreciated! Also, anyone who has had these shipped to them still have the box? I need dimensions as I'm bringing a head back on the plane.
