Danish speaker maker, DALI, has announced a new Phantom in-wall subwoofer/amplifier combination that will be available through Lenbrook Americas to North American music listeners and home theater enthusiasts.

In-wall subwoofers have become increasingly popular in the CI category; DALI joins a growing list of brands like KEF, Monoprice, and SVS who have introduced new models in the category over the past 12 months. In-wall subwoofers save space and can be integrated into both the wall and ceiling for home theater systems.

The new combination consists of the Phantom IW Sub S-100 in-wall subwoofer and CI AMP-2500 DSP amplifier.

The DALI PHANTOM IW SUB S-100 builds on the foundation of the K-60 LP’s bass driver design. It features a 10-inch driver with an extremely stiff, custom aluminum cone and unites long throw capability with an ultra-shallow profile.

The S-100 is also the first DALI speaker to include CSS (Constant Surface Surround) technology which has been co-developed by Purifi Audio, Denmark. The technology offers a unique surround geometry of alternating positive and negative regions, keeping surround modulation to a minimum. The surround surface sound is always constant, no matter the position of the diaphragm.

The SUB S-100 subwoofer has been developed with the PHANTOM CI AMP-2500 DSP amplifier to achieve the best performance within an MDF cabinet (more on the amp in the next section)

As mentioned above, this amplifier was designed to match the needs of the S-100 subwoofer. 

Featuring Class-D amplification (2 x 500 watts), the PHANTOM CI AMP-2500 DSP provides a lot of power with extremely high efficiency and ultra-low distortion. 

Tip: The amplifier can also be bridged into a 1,000-watt mono amp.

With so much headroom, the CI AMP-2500 DSP is not only a great match for S-100 but other S and M-series in-wall speakers and subwoofers.

Tip: The AMP-2500 can power up to four SUB-S-100s.

The AMP-2500 supports rack mount placement and features an adaptive fan control, which keeps fan noise to a minimum. The amp also features a fully featured DSP (Digital Signal Processing) and configurator web interface. Its built-in DSP is tailored with model specific pre-sets to optimize DALI CI models, for the best possible sound experience.
