Description

IS 8 is a fashion style compact full range 2-way loudspeaker system with passive low-loss crossover for near-field reproduction. Comprises a long excursion 8″ woofer for low and mid frequencies with rubber suspension and diaphragm in treated cellulose, and a 1″ dome tweeter for the high frequencies, with ferrofluid cooled voice coil for a better heat dissipation. The loading for the low frequencies is of the phase inversion type with (reflex) tuned chamber.The system’s uniform directivity from 500 Hz to 4 kHz has an average dispersion of 145° x 150° and an average wide-range sound coverage of 150° H and 150° V from 500Hz to 10kHz values which are perfectly suited to a wide near-field listening area without any loss of details for the entire range reproduced.
The acoustic reproduced bandwidth is 45 Hz to 22.5 kHz at -10 dB.

The frequency response of the complete system is ±3 dB from 75 Hz to 19.7 kHz. Flown in free-field it has high average wide-range sensitivity, producing 91 dB SPL @ 1 W / 1 m, (120 dB SPL peak). The maximum allowed power is 80 Watt AES (320 peak).

The enclosure cabinet has a trapezoidal shape and is built by high quality 15 mm. phenolic glued birch with a quality wood veneer painted with black textured painture while the outer finish is in scratch-resistant, waterproof black paint.

Inside, an adequate amount of suitably positioned deadening material eliminates any risk of harmful sound reflection, ensuring a mid range free from coloration and a low range that is deep but always well controlled. The connectors are terminal blocks with large diameter holes able to hold large cross-section cables.

The cabinet has two M8 threaded flying points in the centre of the sides to facilitate vertical flying by means of a special optional bracket. The front protective grille consists in a sturdy painted steel mesh fitted with screws.
