‘Double top’ has long been the accepted term for the style of soundboard used for this series. The DT30OM’s soundboard is a three-layer construction, but it’s certainly not plywood. Instead, we have two very thin layers of Sitka spruce sandwiching a Nomex ‘honeycomb’ core. The idea is to achieve a far higher strength-to-weight ratio than is possible with a single spruce layer – Eastman claims that its double tops are 30 per cent lighter than conventional tops. The concept comes from the classical-guitar world and was introduced during the 1980s by German luthier Matthias Dammann. DuPont developed Nomex as a lightweight, flame-resistant material for the aviation industry and honeycombed sheets are used by luthiers. The Double Top is constructed of 1mm slices of spuce bonded to equally thin slice of printed Nomex.
