What does the 13mm graphene driver do?

The large graphene diaphragm dynamic driver handles bass and lower midrange, giving ASH powerful natural sub-bass, textured body, and a more speaker-like foundation than a full balanced-armature setup.

Is ASH available in universal and custom fit?

Yes. ASH is available as a universal-fit monitor and as a custom-fit monitor built from ear impressions. The custom version prioritizes isolation and a personal shell fit.

Seven-driver hybrid in-ear monitor

ASH

A full-bodied hybrid built around a 13mm graphene dynamic woofer and six precision balanced armatures. ASH uses AAW's TrueXross approach to keep the bass driver, midrange, and treble paths coherent while delivering a powerful, stage-ready presentation.

Design Story

Hybrid weight without losing coherence.

ASH is built from AAW's long-running hybrid idea: use a dynamic driver for the physical foundation that balanced armatures rarely reproduce naturally, then let dedicated armatures take over upper midrange, treble, and super-high extension.

The 13mm graphene diaphragm is tuned diaphragm-first, then constrained with physical low-pass filtering so it avoids unnecessary overlap with the armatures. Driver position, acoustic bore layout, and TrueXross crossover behavior are treated together so the arrival timing stays organized.

The result is a big, textured, bass-capable monitor that still keeps vocal edges, cymbal air, and realistic stage cues intact.

Fitment Options

Choose universal flexibility or custom isolation.

Universal ASH is ready to wear and easy to audition. Custom ASH is built from ear impressions for a personal shell, stronger passive isolation, and a stage-focused long-session fit.

Universal fit

Ready to audition

Ships as a universal monitor with fit accessories. Best for demos, shared use, and quick deployment across listening setups.

Acoustic Architecture

Graphene dynamic bass. Six-armature precision. TrueXross control.

ASH lets the 13mm graphene dynamic driver carry bass and lower midrange, then hands upper bands to six balanced armatures. The 4-way TrueXross system avoids the chaotic overlap that can make hybrid monitors sound powerful but poorly timed.

Sound Signature

Authoritative bass, rich mids, open upper detail.

ASH is tuned for listeners who want physical low-end force without giving up articulation, vocal clarity, and long-session treble control.

Sub-bass

Physical foundation

The large graphene driver moves air with natural pressure, giving kick drums and bass lines real size.

Lower mids

Textured body

The dynamic driver reaches into the lower midrange for weight, warmth, and instrument density.

Upper bands

Armature clarity

Six armatures bring vocal edge, treble definition, and super-high extension without thinning the monitor.

Stage

Coherent timing

TrueXross and acoustic bore layout keep hybrid handoff focused instead of smeared.

FAQ

Before you choose ASH

What is the ASH driver configuration?

ASH uses one 13mm graphene diaphragm dynamic driver and six balanced armature drivers in a 4-way TrueXross hybrid system.

Why use a 13mm graphene dynamic driver?

The large graphene driver gives ASH its physical bass and lower-mid body. Its size, stiffness, and low mass help produce a powerful yet natural foundation.

Is ASH suitable for stage use?

Yes. ASH was designed for band performances, artists, worship events, and listeners who want a large, immersive hybrid signature. Final stage suitability depends on fit, isolation needs, and monitoring volume.

Should I choose universal or custom fit?

Choose universal fit for quicker auditioning and easier sharing. Choose custom fit for ear-impression shells, stronger passive isolation, and a more personal long-session fit.

Good IEM

Deep Bass more detail thanks Null audio

Excellent sound for those who want detail

These earphones are very different from the previous ones I had (triple fi 10 with extra driver turned into customs). The bass is definitely there and sounds really good but it isn't over-emphasized. As usual in this world of people interested in audio, it is hard to come up with the words to describe audio... so I don't mean to sound pretentious or to throw random adjectives around, but I will just describe the sound of these IEMs as "very high-quality, precise, and refined without being showy." In other words, where the triple fi 10 gave you plenty of bass and you went "wow!" but then realized that the bass was unrealistic and muffled other elements of the song, ASH doesn't blow your mind at first but then you find yourself smiling or closing your eyes to enjoy the great presentation of high quality sounds all over the spectrum. Drums especially sound fantastic. The combination of the hi-hat and the bass drum is just really really cool! It demonstrates that ASH can present lows and highs without shyness and keeping the quality. Granted, there are some songs in which the sharpness of the cymbals may be a little too intense. But overall, these are really enjoyable earphones and you know for sure they have great quality capable of revealing everything about your recordings and audio player. Feed them good sources on a good player and you will surely get to know your music in a more profound, intimate, and clear way, give them low-quality content and you will surely feel the need to get better files. Highly recommended!

Pleasantly surprised

I have three sets of in-ear monitors none of which have deicent amount of bass response. I took a chance on the AAW ASH. I used them this Sunday in a live setting for bass monitoring. I couldn't believe the balanced response. From the highs, mids and lows. I could hear it all... finally.

AAW ASH

Very good.

ASH Universal In-Ear Monitor

Built by Advanced AcousticWerkes

Singapore hybrid IEM craft, since 2014.

Those who listen will find the way.

Advanced AcousticWerkes (AAW) designs and builds in-ear monitors in Singapore. Founded by Kevin Wang, AAW works across dynamic, balanced armature, electrostatic, planar magnetic, and hybrid platforms. Every model is shaped by physical prototyping and ear-impression feedback, not preset curves.

ASH distills the hybrid approach into a seven-driver platform: a 13mm graphene dynamic woofer for bass weight, six balanced armatures for mid and treble precision, and TrueXross crossover timing that keeps all seven drivers coherent. It is built for listeners who want physical low-end authority without sacrificing vocal clarity or stage depth.
