Acoustic Energy's 500 Series tweeter features a brand new 25mm carbon fiber dome. Carbon fiber is much lighter and better damped than other typical hard dome materials and provides a lightning-fast, natural sound which will surprise the listener with its neutrality. The new cast aluminum WDT waveguide on the high-frequency driver is positioned close to the mid/bass driver for optimum dispersion and is extremely stiff to reduce vibration being passed to the tweeter, ensuring sweet, clear and natural highs.
The two dedicated 125mm carbon fiber mid-drivers include new oversized 35mm voice coils for low thermal compression and very high motor force factor. Both are mounted within their own dedicated sealed enclosure. The three dedicated low frequency drivers are reflex loaded by a large rear facing rectangular port. The vertical directivity has been optimized to give excellent vertical coverage whilst reducing the energy otherwise wasted on ceiling and floor reflections compared to traditional designs. The net result is a speaker offering much improved results than would be expected in acoustically poor rooms.
The crossover’s low frequency section is mounted on its own PCB board to physically separate it from the mid and high frequency filters and minimize crosstalk between components. All signal path inductors are premium air core versions providing much lower distortion compared to iron core whilst the signal path capacitors are high-voltage metallized polypropylene wound film versions. The midrange motional impedance has been compensated to significantly reduce coloration in the lower midrange
These unique drivers are housed in Acoustic Energy's 18mm Resonance Suppression Composite (RSC) cabinets, evolved from the prestigious Reference Series and featuring the same constrained layer composite to greatly reduce cabinet acoustic radiation, which would otherwise color the sound. The elegant slim-line cabinets are exquisitely finished in Piano Gloss Black, Piano Gloss White or American Walnut wood veneer options. Solid Aluminium bars are supplied to ensure rigid floor-coupling and maximum stability, whilst the stiffness of the metal structure reduces the room to speaker interaction.
