Fresh and visually striking - luxurious compliment Diamond speakers features improved mid/bass drive unit with moulded surround Kevlar Cone, yielding cleaner high-frequency acoustics roll-off and enhanced cohesion. Neodymium-Powered Tweeter Mounted in Cast Alloy Surround With the use of neodymium, the strongest of ‘rare earth’ materials, a concentration of the magnetic field is directed within the area of voice coil excursion. The cast alloy mounting plate has a profiled cross-section to optimize the dispersion of high frequency sound so it integrates flawlessly with the bass/mid-range drivers and produces a fast and more linear response possible. Tweeter diffuser Over the soft-dome tweeter is a metal diffusion grid which, as well as protecting the dome when the speaker is being used without its grille, also irons out high-frequency perturbations right up to 30kHz, delivering a smoother response and crystal-clear treble detailing.
