The IO-5 is a 2-way compact system, ideal for installations where space is at a premium, and features a 5" polypropylene long-excursion mid/bass driver with a Mylar diaphragm horn HF unit in a trapezoidal, high impact, moulded enclosure. Power handling is 60W programme and dispersion is 90 degrees horizontal by 50 degrees vertical. The IO-5T version has a built-in 20W low-loss transformer, designed for high quality audio performance and with installer adjustable tappings on the base of the enclosure. All 'T' versions also have an 8O position in addition to the 70/100V settings.
For installations with more space the IO-8 provides higher sound pressure levels and greater bass extension, using an 8" polypropylene long-excursion mid/bass driver and a Mylar diaphragm horn HF unit. Dispersion is again 90 degrees horizontal by 50 degrees vertical but with higher sensitivity and power handling increased to 120W programme. The transformer size is also increased on the IO-8T to 40W.
Installation of all models is simple and flexible using the included Infin-A-Ball bracket and weather resistance is assured with the use of the moulded enclosures, drive unit materials and zinc-plated steel grilles.
