W-15 (1 pair – 2 units)

Description

Lii Audio W-15 (Pair – 2 Units)

The Lii Audio W-15 is a 15-inch woofer developed from extensive open-baffle experimentation alongside Lii Audio’s full-range drivers. It was created to provide deep, controlled bass while maintaining tonal transparency and seamless integration.

Unlike many conventional woofers, the W-15 has been specifically optimized to perform even in relatively narrow open-baffle designs—delivering impressive low-frequency weight and extension without sacrificing speed or clarity. Its tonal character remains clean and transparent, allowing it to blend naturally with full-range drivers, midranges, or tweeters without disrupting overall coherence.

Technically, the W-15 features a short voice coil combined with an ultra-thick top plate structure, significantly reducing distortion while maintaining excellent control. With a generous 15mm Xmax, it is capable of strong, articulate bass performance with authority and stability.

The driver uses Lii Audio’s proprietary paper cone material, chosen for its wide frequency response and natural tonal behavior. This ensures consistent integration across a broad range of system configurations.

Its dual voice coil design adds further flexibility, allowing parallel or series wiring to match different amplifier requirements and impedance targets. This also enables the W-15 to function effectively as a subwoofer, expanding system design possibilities for advanced DIY or custom projects.

As a fully self-developed Lii Audio driver, the W-15 is an ideal companion to the brand’s full-range units—particularly in open-baffle systems where coherence, speed, and musical balance are essential.

In short, the W-15 is not just a bass driver; it is a purpose-built solution for serious wide-range systems that require depth, control, and seamless integration at the lowest frequencie

1. The King of Open Baffle Bass

The W-15 is a 15-inch woofer specifically engineered to operate without an enclosure. In high-end audio, moving air is a matter of surface area; with the W-15, that area is massive, allowing it to reproduce the lowest frequencies effortlessly while maintaining incredibly low distortion.

2. Outstanding Sonic Characteristics

• Massive Air Displacement: The scale provided by the W-15 is unmatched. You don’t just hear the bass; you feel the pressure in a natural, airy way, without the typical compression found in traditional small-box subwoofers.

• Seamless Integration: Despite its size, the paper cone is surprisingly light for its dimensions. This allows it to be fast enough to keep up with the transient response of high-speed full-range drivers, such as the Silver or Crystal series.

• Natural Timbre: Being a low-loss, open-baffle design, the bass is organic. Low-string instruments and percussion possess a timbral richness that is often lost in sealed or ported enclosures.

3. Key Technical Data

• Sensitivity (91 dB): While this figure may seem lower than a full-range driver’s, in the world of true woofers, 91 dB in free air is an excellent rating that allows for great dynamics.

• Optimized Qts (0.72): Much like its smaller sibling, this high Qts value is the secret to its success in Open Baffle setups, ensuring the bass retains its impact and body.

• Fs of 34 Hz: Its very low resonance frequency allows for a real-world extension that fills the room with a solid, deep foundation upon which the rest of the musical message is built.

4. The Lyric Audio Recommendation

At Lyric Audio Elite, we recommend the W-15 for the audiophile who:

• Has a medium to large-sized listening room.

• Is looking to build an absolute reference system in an Open Baffle configuration.

• Desires an “effortless” sound where music breathes with a real-life scale, similar to the experience of a live concert hall.
