The E4 loudspeaker from d&b audiotechnik is a compact, passive two-way system designed for professional near-field applications requiring precise audio performance and flexible deployment. Built around a neodymium low-frequency driver and a coaxially mounted dome tweeter, the E4 delivers a symmetrical dispersion pattern across both horizontal and vertical axes. This consistent coverage ensures high speech intelligibility and balanced music reproduction, making the E4 suitable for a range of professional settings, including theatres, conference spaces, industrial presentations, broadcast studios, and live event environments. The loudspeaker’s discreet form factor and minimal visual impact enable integration into architecturally sensitive spaces without compromising audio quality. The E4 is also highly effective when used as part of a distributed system in surround sound, delay, or fill applications. Designed for standalone use or in combination with E-Series subwoofers, the E4 loudspeaker provides scalable sound reinforcement for varied technical requirements. Housed in a sealed, injection-moulded enclosure finished with impact-resistant black paint, the E4 is built to withstand both indoor and outdoor use as standard. For projects requiring specific aesthetic considerations, the E4 is available in Special Colour variants. The E4 loudspeaker represents a dependable audio solution for professionals seeking clarity, control, and installation flexibility in demanding environments.
