Spartan IV Adel™

$929.99

The Spartan ADEL was passionately engineered to embody discipline, self-denial, and simplicity, in order to achieve a level of technical excellence that would tenaciously hold its own against other in-ear monitors with a higher driver count.

The Spartan IV possesses immense energy, making it an instant fist pumper with its tight bass, engaging mids, and obscenely clear treble. Detail retrieval and coherence is nothing short of superb. It handles everything thrown its way with ample competence via an advanced 4-way crossover network to rule all 4 drivers.

The Spartan ADEL features the world's first and only patented technology that safely delivers a louder, more spacious, and richer sound – all while avoiding the risk of hearing damage caused by in-ear monitors. When the ear canal is sealed by an in-ear monitor, the driver vibrations create harmful pneumatic pressures in the confined space. The ADEL technology features a secondary eardrum that absorbs the pneumatic pressures produced by in-ear monitors, providing a much safer listening experience. It delivers sound the way it was meant to be heard. With the ADEL, bass sounds deeper, midrange is clearer, and highs sound richer than ever.

The Spartan IV is the most neutral in-ear monitor in the Olympus lineup. No one element of the frequency response stands out over the other, making it extremely versatile among all musicians. Headroom is vast, allowing you to hear yourself and others in the room without having to focus. Bass is tight and deep, mids are even and engaging, and the treble is extended with ample air. The Spartan IV is most popular among guitarists, vocalists, and sound engineers.
“The Spartan is an excellent all rounder and can handle any genre thrown its way. I need to create some kind of shotgunshane award for this one – maybe the “Rock Star of Fame” award?!” Shotgunshane, CYMBACACVUM.com

Description

Fully Adjustable to Your Ear’s Impedance

These ADEL™ Manual Adjustable Modules (MAM) are the most advanced Asius products yet.

This pair features easily adjustable controllers which can be turned while listening to music, and adjustable valves that help regulate pneumatic pressure, and each has a secondary membrane tensioner, as well as an adjustable “secondary” Eustachian tube.

Available to upgrade to the MAM from the B1 or G1 *

MSRP $199.99

Elevated Midrange & Treble

The ADEL™ B1 Auto Modules are designed to bring even more transparency and spaciousness to IEMs and earplugs. This is achieved by a single membrane design, which slightly reduces the bass and brings more spaciousness to the midrange and highs. The ADEL™ B1 is non-adjustable and automatically works to absorb the pneumatic pressures in your ear canal. and also reduces the occlusion effect (boom of your voice) even further to give singers and active wearers fatigue-free listening.

Included in the base price*

MSRP $99.99

Low End Frequency Response

The ADEL™ G1 Auto Modules are designed to bring even more clear bass to IEMs and earplugs. This is achieved by a different membrane design, which slightly increases the bass. The ADEL™-G1 is non-adjustable and automatically works to absorb the pneumatic pressures in your ear canal. and also reduces the occlusion effect (boom of your voice) even further to give singers and active wearers fatigue-free listening.

4 Balanced Armature Drivers

The Spartan ADEL boasts 4 proprietary balanced armature drivers, each individually tuned via our advanced crossover network in order to achieve maximum coherence and resolution. Each and every driver at Empire Ears is subject to strict quality control tests before we apply a patent-pending nano magnetic coating. This conformal coating not only resists moisture and other harmful contaminants but also optimizes performance by shielding each driver’s magnetic field to eliminate all interference.

Using only the most exceptional components the Spartan ADEL’s internals are individually wired and insulated with 7-strand, sapphire and gold, silver-plated copper Litz wires to eliminate acoustic feedback and further soldered with robust, ultra pure quad-eutectic for maximum conduction.



4-way Passive Crossover Network

The Spartan ADEL features a sophisticated 4-way, 3 crossover points network that’s tuned specifically to magnify performance from every driver. Unlike other in-ear monitor companies, Empire Ears does not use filters or dampers to manipulate the frequency curve. That method of tuning forces the drivers to operate outside of its intended frequency range, often duplicating too many of the same frequencies from numerous drivers. This means you’ll have to turn the volume up to hear what you want.

Our method of tuning allows the drivers to behave naturally as our crossover network is engineered to assign the proper frequencies and levels to the corresponding transducer. The end result is a crystal clear, full range frequency response that can be heard even at low volumes.



Quad Bore Design

The Spartan ADEL features 4 precision ported sound bore. Each bore is engineered and hand ported in-house to our exacting clearances in order to achieve optimum phase alignment, consistent performance, and the truest sound possible every time.
