Designer's Notes

“While neutral in tone and a balanced signature throughout, an addictive treble energizes the music, while simultaneously remaining smooth. But our greatest challenge yet was incorporating the low-reaching, impactful bass of the W9 subwoofers, with technical performance rivaling any in-ear monitor on the market; a challenge we can proudly proclaim we have overcome. Offering top-tier levels of transparency and separation, as well as one of the widest sound stages in the industry, our flagship has earned its position at the top of the lineup: a Legend is reborn.”

Proprietary Technologies

Grammy Award Winning Sound

Every aspect of the Legend X was conceived, designed, and crafted to faithfully reproduce what the artist had intended. With the expertise of producers and mix engineers, including 7x GRAMMY Award winner, Jeremiah Adkins, we were able to understand firsthand what they require from in-ear monitors.

synX Crossover Technology

Hybrid Technology

The Empire X series model features a combination of both proprietary balanced armature speakers and dynamic range W9 subwoofers in order to deliver maximum clarity while achieving a powerful low end response. Each model is further tuned with a specially designed synX crossover network to achieve studio monitor levels of audio reproduction effortlessly and faithfully.

After nearly 2 years of relentless R&D Empire is proud to announce the Weapon IX (W9), a proprietary 9mm rare-earth magnet subwoofer with the ability to deliver extreme output, accurate dynamics and sublime sound quality all at the same time. The keys to these performance capabilities lie at the very core of its design, where the woofer is enclosed in a tuned bass-reflex system with a front-firing sound port and rear-firing vent for maximum efficiency.

Conventional dynamic drivers and passive radiators (a speaker without the magnet and coil) often suffer in low octave frequencies and are heavily dependent on internal shell enclosures for volume, limiting form factor and vastly reducing efficiency with limited extension. The W9 is superior in its custom port tuned design, reaching frequencies even lower than its target response while mitigating distortion as the woofer isn’t required to move as far near resonance frequency.

Every W9 subwoofer is hand assembled to our exacting quality standards in our Norcross, Georgia laboratory

Proprietary Drivers

The Legend X utilizes a number proprietary balanced armature drivers by Knowles and Sonion, each one purpose built for a specific target response. Our drivers feature specialized reeds and low-mass diaphragms to reproduce incredible detailed, true-to-recording sound while remaining efficient enough to be powered by everyday devices.

Furthermore each Empire driver utilizes a NASA-born ferromagnetic liquid technology, Ferrofluid, to dampen acoustics peaks and reduce vibrations in combination with our A.R.C. technology. The end result is extraordinary clarity and increased shock durability.

Bespoke Handcrafted Cables

Every Legend X in-ear monitor includes a bespoke, handcrafted Ares II cable by Effect Audio. The Ares II boasts a proprietary blend of 26 AWG UPOCC Litz copper with ultra-flexible insulation for maximum signal speed transmission, performance, and ergonomics. Each cable is terminated in an ultra durable 3.5mm, 24k Oyaide gold plated right angle plug. Alternatively, for our audiophile clientele, we also offer 2.5 and 4.4 balanced terminations at no additional charge.

Effect Audio’s extensive engineering and manufacturing background gives them the edge over all other cables. After extensive testing with numerous other cable manufacturers we’re proud to announce our official partnership with Effect Audio to bring you some of the finest cables in the industry and to ultimately defeat the weak link in IEMs.

A.R.C. Technology

Balanced Armature (BA) drivers are vastly used in the IEM industry due to their small footprint and ultra efficient designs however they suffer from resonant behaviors that may cause peaks, unwanted vibrations, and distortion. To help mitigate this our drivers utilize Ferrofluid between the magnets and armature to provide a wide range of damping values, eliminating the need for a damping screen in the port tube.

Despite this a secondary peak can still occur from the other components interacting with the drivers. Driver peaks can cause fatigue, distortion, and ultimately affect the way music sounds. We sought out to create a remedy for this and after years of relentless R&D we’re proud to announce A.R.C. (Anti-Resonance Compound), a proprietary coating that virtually eliminates unwanted vibrations and resonance from within IEMs.

A.R.C. effectively increases the mass of the components it’s applied to: every driver, crossover, and sound tube. This gives the internals more solidity while serving as a dampener to absorb the unwanted resonance instead of reflecting them out of phase. With A.R.C. clarity is increased substantially, bass is deeper, and the IEM becomes more efficient overall.
