Product no: 9000-0061-1345

Product information

General

Designed for smaller DJ set-ups as well fixed installations, the Devine Onyx 18SXA is a powerful bass bin loaded with an 18" woofer and a 2.1 amplifier module that's ready to drive two passive satellite speakers like a pair of Devine Onyx Series 10s. So you can get the right sound at the right time, this active sub features a DSP section with four built-in modes (Main, Music, Live and Speech) while round the back, you'll find a range of controls including a phase switch, a ground lift switch and a stereo mono set-up switch. The Onyx 18SXA boasts a peak power of 1,000W and comes finished with two XLR/TRS combo line inputs, two balanced XLR link outputs and two SpeakON outputs. Just keep in mind that the passive speaker outputs are only compatible with passive speakers with an minimal impedance of 8 Ohms.

Devine Onyx 18SXA Active Subwoofer

Très bon rendu. Panneau arrière très conviviale, possibilité de connectique complète. En combinaison 2 caissons 18SXA avec 4 JB SYSTEM PSA15 ... ça pousse très fort. Je vous le recommande ce matériel.

Devine Onyx 18SXA Active Subwoofer

Groot en zwaar maar geeft voor onze toepassing buiten in open lucht niet voldoende resultaat. Weinig of geen meerwaarde tov de huidige bass die uit de Alto415 speakers komt.
