Danish gold rush – Børresen just kicked it off with the Gold Signature versions of their M1 – M6 speaker models. Upgrades include new stainless-steel driver baskets cryo treated then coated in their most advanced surface skins. The four-layer driver membranes apply spread-tow carbon-fibre skins around an aramid honeycomb core then add an external Signature-treated titanium layer. The motor system gained a new copper, silver and gold pole ring for further inductance reduction. The internal hookup wiring has become Ansuz Gold Signature. All of these upgrades are also available to existing M-Series owners.
