The i-8 was designed to provide a compact low frequency solution for a variety of applications. The unique design provides unprecedented sonic depth from an enclosure of this size. At home either as low frequency extension in cafés and bars or as an extra sonic effect in theatres and museums, the added low frequency that the i-8 can produce makes it suitable for many situations. The enclosure contains four high power 8” (203mm) neodymium LF drive units, loaded as two compound isobaric pairs. This design gives a usable response down to 35Hz, without any artificial equalisation. The i-8 can therefore add ‘depth and warmth’ to any system, even where larger subwoofers would normally have been used. The rugged enclosure is constructed from premium 15mm (3/4”) multi-laminate Birch plywood, rebated, screwed & glued together for maximum strength. Sixteen M10 threaded fixings are provided (four each side) to allow suspension of the enclosure if required. Connections are via two NL4 connectors on a recessed rear panel for input & enclosure link. The enclosure is finished in black or white textured paint as standard, however RAL colour matching and weather protection options are available. Two perforated steel mesh grilles covered with acoustically transparent black foam protect the drive units from damage and moisture. For service purposes, the rear pair of drive units can be accessed via a removable door on the rear panel of the enclosure. The i-8 requires active high/low pass filters and a single amplifier channel capable of delivering 600-1200W RMS into a 4 ohm load. For optimal results, either the DQ Series Advanced System Amplifiers, or the AQ or AD Series amplifiers combined with DSC48 processors should be used.
