The Proel S series: Compact and powerful

The Proel S18A is the largest model 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 S18A 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 S18A 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 131dB, covering a frequency range of 36-160Hz. 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 (36kg, under 80bs), the Proel S18A 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 S18A 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 S18A 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.

che dire...solo Wow!

Diciamo subito che non è un subwoofer facilmente trasportabile date le dimensioni ed il peso, per fortuna ci sono le ruote già incluse e montate che ci vengono in aiuto, le frequenze sono davvero profonde e non si sente del rumore dello sfiato dell'aria, ho potuto così constatare inoltre un suono davvero pulito nelle frequenze basse, date le caratteristiche ottime citate prima, ed un'ottimo suono nelle frequenze fino agli 80Hz, ovvero senza aver pigiato il tasto posteriore, per il mio utilizzo è ottimo, in generi che variano da house, latino, reggae, trap!

Hi Thomann!

We ordered this subwoofer in order to strengthen the lower end of our PA system. Our system has consisted of two Yamaha DXR15's, which have taken care of the whole frequency spectrum. Well, adding the sub improved the overall sound a bit, but there's a limit to what one subwoofer can do.

This sub clips at a pretty early stage, so if you are going to make a crowd of 100-200 persons drown in bass, you'd probably need 4 of these bad boys. Of course one could say that you get what you pay for, but I suspect you might get more decibels per euro with some other products.

One of the greatest advantages with this product was the decent crossover, connectivity and the weight. I can tell you, I've moved way heavier subs than this, and it was almost enjoyable to move this one around. Also the freedom of adjusting the crossover frequency was really nice, you don't get that with every subwoofer.

Where would I use this sub? This sub is probably loud enough to make a home system work very nicely, maybe even smaller gigs. If I would need to transport a compact PA system around a lot, I would probably get one of these.

Still, I probably won't buy this product any time soon, unless a very specific need appears. Buy it if you need something portable and okayish, otherwise reconsider your options.

Yllätävän hyvä

Sub ei aluksi houkutellut muuta kuin hintansa puolesta. Speksit ei hirveästi mairitellut mutta päädyin tuotteeseen kuitenkin.. ONNEKSI! Sen verran hyvin potkii ja roudauksen keveys hymyilyttää aina. Näitä piti tilata lisää. Nyt neljällä alapäällä kelpaa keikkalla vähän isommassakin tilassa.
