Biamp Desono DX-IC4LP-W 4.5” Low-Profile, High Efficiency Coaxial I...
Product Overview
The Biamp Desono DX-IC4LP is a 4.5-inch low-profile coaxial in-ceiling loudspeaker, sold as a pair, with an HF compression driver. At only 3.4 inches deep, it solves space problems that competing products cannot. It installs quickly and provides uniform coverage. It operates at 8 ohm or on 70 V/100 V systems.
Product Description
Suitable for paging, background music, or augmenting larger systems, the DX-IC4LP is a versatile performer. Uniform voicing among the Desono DX family makes it an easy match to other models in the series. Its genuine coaxial design uses separate magnets for the LF and HF drivers, reducing distortion and delivering high sensitivity that permits 3 dB to 6 dB greater output while requiring less amplification power. SpringLock mounting clamps speed installation, and conduit knock-outs on the input cover meet plenum air-handling requirements. The DX-IC4LP is ETL listed to UL1480, UL2043, and CSA62368-1. Included accessories cover standard installation needs.
Key Features
- Sold as a pair — Each order includes two DX-IC4LP in-ceiling loudspeakers.
- Shallow 3.4-inch depth — A low-profile back can solves space problems where above-ceiling clearance is limited.
- Coaxial wide dispersion — A genuine coaxial design with separate LF and HF magnets provides consistent dispersion up to 16 kHz with low distortion.
- Fast installation — SpringLock mounting clamps speed up ceiling installation.
- Selectable operation — A built-in autoformer supports 8 ohm or 70 V/100 V operation.
- Plenum rated — Conduit knock-outs and UL2043 listing meet plenum air-handling requirements.
Typical Applications
The DX-IC4LP suits commercial meeting spaces, multi-purpose rooms, and training rooms for paging, background music, or augmenting larger systems where shallow ceiling depth is required.
