Have a very nice set of Barzilay Speaker Cabinets loaded with LE14As LE20s and LX8 crossovers they have not one bit of damping material inside the cabinets and lack bass Is there anything else I can add beside ewaves to these to make them sound better.I love the cabinets and do not want to use them just as furniture as they sure are lookers I added a picture to see how nice they are.Thanks
