The Proel S series: Compact and powerful

The Proel S15A is one of the mid-sized models in 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 S15A 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.

Easily adjustable for every application

Like the other subs in the S series, the Proel S15A 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 129dB, covering a frequency range of 40-160Hz. 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 relatively low weight (26kg, under 60lbs), the Proel S15A is ideal for in-demand DJs, busy mobile entertainers, and live musicians of all kinds – in fact, anyone who primarily plays at 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 S10A 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.

Their equipment is trusted worldwide for its reliable performance and simplicity.

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 S15A active HBP subwoofer - as well as all the larger models in the series, of course. 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.

Que dire...

Tristan D 20.07.2021

Ayant déjà eu des ELX 118P, Yamaha DXS18, the box CL115, Octave1000... Donc des modèles puissant et aussi des petits modèles :
J'ai acheté ce modèle pour remplacer un Audiophony Octave.
Les caractéristique étant totalement identique, je m'attendais à quelques chose de très similaire.. bon... Pas du tout..
Le Audiophony octave est un vieux modèle avec un puch incroyable, une basse sèche et percutante. C'est ce que je recherche avant tout.
C'est loin d'être un mauvais produit mais en ayant acheté un 15pouces avec une réponse en fréquence plutôt haute pour avoir des basses percutantes... et ben non malheureusement ça ne répond pas à mes attentes..
Cependant, une basse très correct pour son prix. Un poids défiant toutes concurrence (UN PLAISIR A DEPLACER ET AUTILISER !!) et un aspect visuel pas du tout bas de gamme fais très plaisir.
Les roulettes incluent sont très bien !
Dommage que les boutons soient fragile. Je suis très très soigneux, et pourtant dès la première utilisation, le cache du bouton de réglage de fréquence est tombé et je ne l'ai jamais retrouvé... Pour un produit neuf c'est pas top.
Si Thomann lis cette avis, un petit geste ou une reprise serait la bienvenue...

Guter Einstiegsbass

Die Soundhandwerker 22.11.2018

Ich habe eine ProelS15A zusammen mit meinen Mackie Thump15 ausprobiert. Sie läßt sich super wegen des geringen Gewichts und durch die versenkten Griffe transportieren. Alle Rollen gebremst und kein Klappern beim Betrieb. Bei null Pegel wirklich null Rauschen. Es gibt auch keine Luftgeräusche bei Vollast. Leider passt der Endpegel nicht zu den Thump, die ich höchstens bei 50% laufen lassen habe. Dafür ist der Limiter aber seidenweich und das Eingreifen nicht zu hören. Für mittlere Raumgrößen und mit den passenden Topteilen ist die S15A eine gute preisgünstige Alternative.

Presque parfait

Wildrummer 22.12.2019

Des basses très profondes, qui descendes très bas pour un 15 pouces.
Cependant, il sature légerement sur des kicks assez puissant. Cela ne s'entend pas mais la led s'allume rouge...
Roulettes très bonnes et très pratiques, comme le caisson niveau qualité de fabrication, cependant, même si on ne le touche pas souvent, le potard du volume semble assez fragile..
En clair, des basse très profondes et très juste qui tape bien même si a haut volume les kick saturent très légèrement.
Rapport qualité/prix excellent!
