Devine Onyx 15SXA Active Subwoofer

Excellent sound. Heavier than I expected, but provides a very stable base to the Devine12 speaker. Plenty of options on the inputs. If I have any cause to complain about this speaker, it's things like not having a through power connector, like a C13/14 pair. The stencilling on the label could do with being a bit brighter and larger, because it's going to be dark round the back.

Devine Onyx 15SXA Active Subwoofer

Really meaty sub, bigger and heavier than I expected, but not unmanageable. Niggles... wish it had a through C14 power connector, or Neutrik pair because you ARE going to use this with a pole and main speaker for sure. But the range of controls and options makes this super versatile. The stencilled labels on the back could also be a little bigger and heavier because this is a beast you will want to put in the corner, and it gets dark back there.

Devine Onyx 15SXA Active Subwoofer

In december heb ik twee van deze subwoofers gekocht en ik heb er geen spijt van. Een mooie, stevige kast met een diepe bas die een goede aanvulling is op mijn tops.

Aanrader voor de amateur en semiprofs. Veel bas voor weinig geld.

Devine Onyx 15SXA Active Subwoofer

J ai fait la acquisition du caisson il y a un peu plus de six mois. Avec le recul d utilisation, je vais communiquer mon avis perso. Esthétiquement je le trouve sympa. Il est très lourd il faut rajouter des roulettes. Le son est bon couplé avec deux enceintes passives.Je ne l ai pas encore mesuré. A fort volume il ne grésille pas, le dsp est bien. Le seul hic, il chauffe un peu et il manque un ventilateur et la housse est vraiment trop chère. Je le trouve mieux que mon vieux powo et aussi bien que mes ld system sub 18 GT qui tapent pourtant vraiment forts.
