The DALI SUB E-9 F features an innovative 9-inch long-stroke woofer made from pure aluminum. This cone is extremely stiff and lightweight at the same time, ensuring an impressive transient response. The driver’s ability to start and stop instantly is at the core of DALI's design philosophy, allowing the subwoofer to seamlessly blend with your main speakers. Additionally, its special structure eliminates the need for a dust cap, ensuring a perfectly linear piston movement that keeps distortion to an absolute minimum.

The power management is achieved with absolute precision thanks to the built-in Class D amplifier, which delivers 170 Watts RMS steadily, with peaks reaching 220 Watts Peak. The amplifier is highly linear and reproduces the audio signal with complete integrity and clarity. It has enormous power reserves (headroom) and durability to comfortably handle the most demanding and explosive cinematic effects or the intense dynamic changes of your music, offering maximum acoustic pressure of 111 dB.

The compact cabinet made of MDF wood is built according to DALI's strict quality standards and is available in elegant Black Ash or White finishes, with a refreshed matte satin front baffle. To completely eliminate unwanted aerodynamic whirlpools beneath the subwoofer, the cabinet is raised 30 mm off the floor using four large polymer spikes. This arrangement achieves ideal acoustic decoupling, increases performance, and provides much greater flexibility in placement.

The DALI SUB E-9 F offers excellent flexibility and universal compatibility with almost every modern or older amplifier and AV receiver on the market, featuring stereo RCA inputs (low-pass filtered) as well as a dedicated mono LFE input. Thanks to its relatively compact size, it allows for easy integration into your space — ideally in a corner or along the wall to maximize bass dispersion — and is the ultimate acoustic complement for DALI's popular OBERON, FAZON, and SPEKTOR series.
