As stated in a few other posts, Iím going to be building new cabinets for some 10Aís I recently pick up. A decade or two in a damp basement has left the original cabinets warped and horribly musty smelling. I intended to keep the cabinetsí internal volume and dimension the same. Some changes Iím curious aboutÖ flush or recessing of the drivers? Placement of the tweeter, is higher on the cabinet ok? Tweeter orientation, is horizontal optimal or is vertical ok/better? Can you add too much mass to the cabinet?
