# 40mm MDF sculpted baffle – stiff, heavy and rigid and minimises diffraction.

# Recessed drive units flush with the baffle surface – minimises diffraction.

# New tweeter has wide band design extending the amplitude response beyond 20kHz audibility to 50kHz to correct the phase response from 8kHz to 20kHz within the audible band. This preserves the harmonic structure of sounds and the stability of the stereo image.

# Smooth tweeter faceplate contours prevent diffraction and cavity effects.

# 10 point fixing maximises contact between drive unit and baffle.

# New design bass units have aluminium flux control rings around the voice coils and copper caps on the pole pieces – linearises the voice coil motional impedance to reduce non linear (3rd order) distortion products caused by varying voice coil inductance.

# Bass unit development using Klippell™ analysis equipment to minimise offsets and linearise the suspension components.

# On/Mute (energy saving mode) via the Tannoy logo push switch.

# LED indicator shows Active/Energy Saving modes.
