The Proel S series: Compact and powerful

The Proel S12A is one of the mid-sized members of the S series - a new range of compact and powerful subwoofers that have been developed to complement the brand's wideband speakers. The lightweight and yet robust plywood construction comes with a particularly durable polyurethane finish. The subwoofer is fitted with Proel's new Class D amplifier module with Switch Mode Power Supply, and is capable of generating enormous power in an enclosure specifically designed to be compact and easy to transport. The Proel S12A is equipped with a high-excursion woofer housed in a hybrid bandpass (HBP) configuration: This innovative design ensures greater efficiency compared to directly radiating subwoofers, as well as improving the acoustic coupling of the tuning channels with the air outside the unit. By reducing both distortion and air turbulence, Proel has created a subwoofer with a defined sound and a deep, powerful bass response.

Proel S12A active subwoofer

Easily adjustable for every application

Like the other subs in the S series, the Proel S12A has a stereo preamp, as well as a 24dB/oct. crossover filter that allows users to manually select frequencies and activate phase reverse. This hybrid bandpass subwoofer generates a continuous output of 600W at a maximum SPL of 127dB, covering a frequency range of 43-160Hz. The connection panel comes equipped with an XLR/jack combination socket, and as such it can be used with devices with balanced or unbalanced outputs. The link left and link right sockets are set up as XLR outputs in parallel to the line input, providing a balanced line-level signal with a high-pass filter for connecting a satellite speaker. There are also switches for ground lift, low-pass, and high-pass, as well as rotary controls for the input level, level control, and phase.

For 24-hour party people

Thanks to its compact dimensions and low weight (19kg, or just over 40lbs), the Proel S12A is ideal for in-demand DJs, busy mobile entertainers, and live musicians of all kinds - in fact, anyone who primarily plays at small to mid-sized venues and needs a sub that is solid, easy to transport, and affordable. Its sonic characteristics are excellent too, especially the adjustable frequencies, which keep interference with any satellite speakers to a minimum and allow users to select the optimum frequency ranges for their preferred genre of music. Another useful feature is the automatic output attenuation when the device is switched on or off – no risk of level peaks damaging the woofer or the user's hearing! All in all, the Proel S12A active subwoofer promises to be a consistently reliable source of quality low-end sound, especially considering that the trend towards running a PA with a second sub shows no signs of abating.

Phase reversal for subwoofers

In the specific context of subwoofers, the term phase essentially refers to the timing of the low-frequency sound waves. By adjusting the phase, users can alter the positive movement of the woofer's sound cone, and thus the beginning of the sound wave. Phase reversal can be useful (or even necessary) when the acoustic signals generated by the woofer need to be adjusted to suit a specific room and speaker configuration, eliminating the need to change the position of the speakers entirely, which is virtually impossible in day-to-day operation. Fortunately, phase switching is an integral part of the design of the Proel S12A active HBP subwoofer, as is the case for all models in the series. This function also enables the optimum utilisation of the woofer's extended frequency range, further underlining its potential as a cost-effective and efficient solution on the low-frequency market.

Chouette petit sub
InvaderOne 02.07.2025
La connectique est largement suffisante et le rendu n'est vraiment pas loin du 15 pouces qu'il remplace.
Associé à 2 top 10 pouces (the box Pro DSP 110) c'est vraiment une bonne combinaison pour de petites soirées.
La finition semble sérieuse, la housse Proel est parfaitement adaptée.
