High-Quality DSP Sounds with Easiest Operation!
The subwoofer from Pronomic's C-Series impresses with clear, powerful sound at an incredible price. Reliable technology and a stage-ready enclosure set a new standard for this speaker.
Powerful Speaker
The C-118SA features an 18" speaker driven by a 3" voice coil. Combined with the 800 Watt (RMS) amplifier, it achieves a maximum volume of 126 dB.
Smart Technology
The subwoofer has two combo-format line inputs, and two XLR outputs for signal pass-through. Using the rotary control and display, all important settings can be intuitively made. The front LED optionally indicates power on (blue) or internal limiter activation (red). Alternatively, the LED can be completely switched off.
DSP Presets and Additional Settings
Four sound presets are included for different applications:
- Live: Very linear with very low cutoff frequency
- Music: Slight bass boost at 50 Hz
- DJ: Stronger bass boost at 50 Hz
- C-Series: Tuned filters for Pronomic C-Series speakers
To achieve the best sound results, the subwoofer's crossover frequency can be adjusted to match the tweeters used. Polarity and a delay of up to 16 ms are also adjustable.
Robust Enclosure
The sturdy 15 mm MDF panels are coated with a durable textured lacquer. Large handles are located on both sides. As expected in professional gear, the speaker flange for possible satellite speakers features an M20 thread.
Solid Low-End Support for Your Stage!

The delay function is indeed class, but makes absolutely no sense in such children's room subs.
They sound to tortured, so you should separate at 80hz if you need it louder. The limiter also jumps in much too early (also significantly below 0db)
All in all, although cheap, but not seriously to use unfortunately ...

So I am thrilled with everything.
PRICE SHIPPING AND QUALITY.
I'm already looking forward to the next order.

Wir bedauern sehr, dass die Subwoofer Ihren Ansprüchen nicht gerecht wurden!
Natürlich tun sich solche doch vergleichsweise günstigen Subwoofer schwer, mit z.B. dem von Ihnen genannten LD Stinger Sub oder anderen Markenprodukten mitzuhalten. (Der Stinger geht ja nach dB SPL auch doppelt so laut, wie das der Pronomic tut.)
Dennoch sind unsere Kunden bisher immer äußerst zufrieden mit dem Subwoofer.
Uns ist auch klar, dass das Modell für große Beschallungen oder Musikevents welche extrem viel Bass erfordern wahrscheinlich nicht ausreichen wird, dafür ist es was Lautstärke und Leistung angeht einfach nicht ausgelegt.
