Active and Beam Steering array speaker

Active Column Speaker Category
Fulgor Service produces the best professional active column audio speakers currently on the market, considering the price-to-quality ratio and the unique proprietary technology with which the digital speakers operate — namely a common two-wire bipolar cable. All speakers are equipped with DSP and fall into two categories: those with Beam Steering control and those without electronic directivity control.
The main quality shared by all Fulgor Service active speakers is mechanical or electronic directivity.
In both categories, all column audio speakers consist of drivers mounted in an array, so the line arrays vary in height depending on the model and specifications. The drivers that make up the speakers are 3.5-inch self-supporting basket units, specifically designed to reproduce the frequency range of the human voice and achieve maximum speech intelligibility in any environment.
These professional audio speakers are engineered, designed, and built for fixed installations.
Both categories of professional active audio speakers are designed for installation in churches or places of worship, conference halls, meeting rooms, congress halls, multipurpose rooms, paging systems, and distributed audio systems — wherever maximum speech intelligibility is required with minimal visual impact.
Design matters — both for sound and aesthetics
All active speaker models share the same appearance, using the same materials: an extruded aluminium back panel that forms the acoustic enclosure, and a calendered and stretched grille that maximises open surface area to avoid altering sound wave output, while also protecting the precious 3.5-inch self-supporting drivers. On the Activo and RAE lines, we use 60W polypropylene drivers. The mechanical and structural quality, along with the components used, ensure unaltered sound reproduction over a very long time, even in the most demanding environments.
The Vertical Activo S – L – XL – VR active column speaker range
Let's explore the first category: the Vertical Activo S – L – XL. All three models feature an internal PCB with an onboard DSP and the proprietary operating system (using a two-wire bipolar cable for both power and signal). The Activo S houses 4 x 3.5-inch transducers, the Activo L has 9 drivers, and the Activo XL contains 12, with array length varying accordingly. These column speakers are particularly suited for multipoint audio system installations. The true innovation and strength of the speaker — or rather the system — is that it requires no rewiring of the structure, as the Activo system operates on a standard bipolar cable, typically the one already present from the previous installation. Once the speakers are installed, simply configure the DSP on each Activo unit, adjusting volume, EQ, and above all delay as needed to time-align the sound from all speakers. This way, the energy emitted by each column speaker adds together without reflections or overlaps, delivering a perfect, homogeneous, and above all intelligible sound level — without introducing additional reverberation into the space.
These digital active column speakers are suitable for multipoint audio systems and are used in mid-to-high level professional audio installations. Speaker configuration is carried out via a dedicated controller or via Wi-Fi.
The Vertical VR 816/824 active column speaker range
The second category of active column audio speakers is called Vertical VR. These professional digital active speakers with beam steering control make no compromises. Thanks to the combination of a mechanical array and proprietary technology, the Focus delivers impressive sonic directivity — achieved not only through the mechanical construction but also through an algorithm driving the powerful DSP that controls 8 Class D amplifiers. The project was born following the success of the Vertical Activo line; the market demanded an efficient and practical product that could interface with the Activo system. The VR speaker therefore operates on a single bipolar cable, retaining all the features of the Activo speakers, with the added capability of directivity control, or beam steering. By emitting a directional sound lobe — called the Focus — with very narrow vertical opening and a wide horizontal dispersion, the Focus speaker allows the installer to tilt the lobe down to as low as 16°, even at higher frequencies. Thanks to these design features, a single Vertical Activo VR speaker can control the sound beam over distances of more than 30 metres, with a maximum Focus inclination of ±16°, guaranteeing speech intelligibility and warm, natural tonality even in large and acoustically challenging spaces. The VR digital speakers, like the Activo, use the same configuration method — via a dedicated controller or Wi-Fi.
The VR speakers are fitted with individual 3.5-inch, 60W RMS, 8-ohm polypropylene drivers. The soft pneumatic suspension ensures a high mechanical excursion for outstanding performance — suitable for advanced professional mono or multipoint audio systems where directivity, throw, and quality cannot be compromised.
In the professional audio world, users and designers need to be able to incorporate active speakers into predefined audio projects. For this reason, the website also provides .GLL files for all speakers, which can be imported into acoustic design software to scientifically verify the performance of each professional active speaker. Please note: this should not be confused with acoustic soundproofing, which is covered in a separate section of the website featuring dedicated materials called Controltec.
