The X: SIDER series offers an effective and reliable solution for a wide range of professional applications -from medium to large events. The system consists of a sturdy but lightweight trapezoidal satellite which can be paired with a massive 2x18 sub. Both have dedicated digital amplifiers with their own DSP, and can be rack mounted.

X:SIDER has been created as a horizontal array system or as a support array , where coverage can be perfectly determined by the number of satellites being used. Thanks to the modularity of X: SIDER you can build a system suitable for any situation. For additional horizontal coverage, simply add satellites and to optimize the response at low frequencies, add multiple sub units.


The amplifiers are equipped with a remote control interface so you can keep the whole system under control at all times - making corrections to the acoustics as the event may require.

To complete your VERSE system, we’ve developed and designed all the necessary hardware for hanging and installing the satellites - with an exclusive ultra-fast coupling system; the subwoofer is equipped with a handy removable rack for easy transport.

VERSE X:SIDER: a sound system solution for those requiring power, quality and flexibility for medium and large spaces.

Power, extreme configurability, robustness, care in construction and reliability are the guidelines behind this project.

X:SIDER has been designed to work like a horizontal Array. The system provides a wide-angle sound dispersion and its speakers, subwoofer and satellites, are passive to conserve weight so they’re easier to transport and install. To ensure ultimate strength and durability, the X;SIDER uses the best materials available on the market.

Thanks to the convenient attachment options, it’s extremely easy to assemble and disassemble the X:SIDER system. 

The subwoofer is equipped with quick-fit cart. The heart of the system consists of a digital processor with proprietary technology that allows you to calibrate and optimize the acoustic response. The power amplifiers have the highest quality circuitry which which gives them greater efficiency and extreme robustness.



X: SIDER 15 Amp and X: SUB 218 Amp represent the real heart of the X: SIDER, the source of power and incredible sound quality of this speaker system. They are designed to be exceptionally sturdy instruments that can be utilized in any situation, even in the most extreme applications. 


 The “Ethernet” serial connectors  allow access and total control of X: SIDER. All presets prepared by the VERSE technical staff can be edited and customized using just a PC and the D: SP Editor (optional). The software provides access to all system parameters, with a real unique versatility and flexibility of use. Upon request, VERSE is able to provide X: SIDER, in the configuration selected by the customer, pre-wired and mounted in a standard 19 " rack, complete with Power Box.  Immediately ready to use!
