i-C15

The i-C15 is the larger of the dedicated passive installation loudspeakers from EM Acoustics – loudspeakers intended to provide a high quality solution in fixed installation environments where some of the features popular with “mobile” products are not required. The i-C15 has a frequency response of 55Hz – 18kHz which can be extended by adding any subwoofer from the EM Acoustics product range for a more full range system solution.
  • Conical 80° dispersion pattern
  • Premium 15mm multi-laminate birch plywood enclosure
  • Multiple threaded rigging points compatible with OmniMount and Powerdrive brackets
  • Various dedicated installation hardware options available
  • Impact and weather resistant black or white textured finish as standard
  • RAL colour and enhanced weather protection options

The compact and sleek enclosure contains a 3” (75mm) diaphragm, 1.3” exit HF compression drive unit coaxially loaded by a 15” (381mm) LF drive unit, linked via a signature EM Acoustics internal passive crossover network. Both the LF and HF drive units share the same magnet assembly, reducing overall weight and enclosure profile. The coaxial drive unit arrangement provides a smooth conical 80° dispersion pattern for maximum coverage, allowing the speaker to be deployed in either a vertical or horizontal orientation while still retaining the same dispersion pattern. Optimal reflex tuning extends low frequency response to allow the i-C15 to be used stand alone for speech or moderate duty music reinforcement applications, or with subwoofers from the EM Acoustics range to further extend LF response.

The robust enclosure is constructed from premium multi-laminate Birch plywood is finished in an impact and weather resistant black or white textured polyurethane finish as standard, though RAL colour matching and enhanced weather-protected outdoor options are available.

The enclosure contains four M10 exposed-thread rigging points specifically for use with optional horizontal or vertical accessory cradles. Additionally, four M8 threaded points are provided on one of the angled back faces for installation using OmniMount™ Series 60 or PowerDrive Series 100 bracket products. The asymmetrical cabinet shape permits installation closer to walls or ceilings than a traditional trapezoidal enclosure, and also allows the i-C15 to be conveniently used as a stage monitor with a choice of two wedge angles.

The front of the loudspeaker is protected by a rigid stainless steel grille backed with acoustically transparent fabric for a stylish and discreet appearance. A recessed panel on the rear of the enclosure provides two Neutrik® SpeakON™ NL4 connectors for input and enclosure link.

The i-C15 requires a single amplifier channel, and the use of external DSP is recommended for system protection with high pass filters and limiters – as such it is recommended to be used with EM Acoustics’ range of Advanced System Amplifiers. It is however possible to use other DSP-enabled amplifiers, or conventional amplifiers with external DSP. Suitable DSP settings are provided on the EM Acoustics website. The i-C15 requires a single amplifier channel capable of delivering 750-1000W RMS into an 8-ohm load.
