Signature 7NT
See nothing, hear everything
The Signature 7NT is a true Kevlar woofer based audiophile in-wall monitor. The Aluminium baffle has very high rigidity, which with
the 7in cast frame improves bass speed and attack. The crossover contains polypropylene capacitors resulting in transparency
throughout the frequency range. The inverted drive unit configuration brings the Nautilus tube technology tweeter closer to ear
height and the speaker has a switch to allow the HF level to be adjusted. The speaker can be bi-wired via high quality gold plated
terminals.
