I’ll jump in early with the reply.
The Denon DJ Axis speakers were released shortly before Denon DJ was acquired by global music giants, InMusic (The name behind the brands which rock the professional music world, including Akai, Numark, Alesis, Alto Professional, Mixmeister, to name but a few). One of those InMusic brands, Alto Professional, are predominately manfucaturers of excellent PA and DJ speakers and systems of various sizes.
Speakers, whilst being versatile, and sounding great etc, are also required to meet different customers feature requirements and specifications etc.
For Denon DJ to continue with 2 different Two Way speakers and a Sub-woofer, (The remaining stock of Denon DJ Axis speakers were primarily snapped up by the Audio/Visual market - with no central stock remaining ), when the Alto Professional brand offers an immersive range of feature-rich cabinets, systems, options and power outputs, would have been somewhat choice-restrictive compared to the Alto Professional range.
Depending on the type of gigs which you perform at, and the sizes of venues which you play, then you’ll certainly find an ideal solution in the Alto Professional TruSonic (TS) or Alto Black ranges of speakers.
