Developed from the ground up by DALI for ultimate performance, the PHANTOM IW SUB S 100 subwoofer is based on the same principles as the K-60 LP bass driver. The 10-inch low profile and versatile in-wall sub features a stiff, custom aluminum cone that unites long throw  capability with an ultra-shallow profile and sealed enclosure. This is the first DALI speaker to  include the CSS (Constant Surface Surround) technology which is co-developed by Purifi Audio,  Denmark. The technology offers a unique surround geometry of alternating positive and  negative regions to keep surround modulation to a minimum. This allows the surround surface  sound to be constant no matter the position of the diaphragm.

The PHANTOM SUB S-100 has been developed alongside and is to be amplified by the  PHANTOM CI AMP-2500 DSP. This ensures compatibility and maximizes performance potential  to achieve consistent performance in any installation. The PHANTOM CI AMP-2500 DSP  features 2,500 watts of Class-D amplification enabling effortless power with extremely high  efficiency and ultra-low distortion. This rack-mountable powerhouse can also be bridged into a  1,000 watt mono amp and features an adaptive fan control to keep fan noise to a minimum.  

The CI AMP-2500 DSP has immense headroom making it the perfect power source for the  PHANTOM S and M series or allowing for up to four PHANTOM IW SUB S-100 in-wall  subwoofers. The amp also includes fully featured DSP (Digital Signal Processing) and  configurator web interface. The built-in DSP is tailored via model specific presets to optimize DALI CI models for the best possible sound for each audio installation.  

The system can be configured wired or wirelessly with access to the DALI CONFIGURATOR app  for quick and easy audio system setup via a smartphone. The app enables the user to manage  sound zones, inputs/outputs, firmware updates, import of speaker presets and access to  professional EQ settings.
