Developed using advanced German acoustic engineering principles, the AST-250 combines a lightweight composite diaphragm with ceramic reinforcement technology to deliver outstanding sensitivity, extended frequency response, and exceptional musical detail.

Designed for modern SQ and DSP-based audio systems, the AST-250 provides accurate vocal harmonics, refined instrument reproduction, and a wide, immersive soundstage that elevates the entire listening experience.

Its compact architecture, durable metal housing, and innovative quick-lock mounting system make installation easier and more versatile than conventional tweeters.

Technical Specifications

ALCHIMIST Acoustic Technologies

C.C.D™ Ceramic Composite Diaphragm

At the heart of the AST-250 is the newly developed Ceramic Composite Diaphragm technology.

A specialized synthetic fiber diaphragm is reinforced with ultra-rigid ceramic particles to increase stiffness while maintaining an extremely low moving mass.

Benefits include:

• Higher sensitivity
• Faster transient response
• Reduced harmonic distortion
• Improved detail retrieval
• Extended high-frequency performance

The result is cleaner, brighter, and more natural high-frequency reproduction without harshness or listening fatigue.

H.R.W™ High Resolution Waveguide

The optimized front acoustic chamber improves sound dispersion and phase consistency, allowing vocals and instruments to be reproduced with exceptional focus and realism.

This technology contributes to a wider soundstage and more accurate imaging.

R.M.C™ Resonance Management Chamber

An internal acoustic damping structure reduces unwanted resonances and reflections behind the diaphragm.

This improves clarity and ensures a smoother, more natural frequency response.

N.D.M™ Neodymium Dynamic Motor

A high-efficiency magnetic motor system generates powerful magnetic flux while maintaining a compact physical size.

The result is enhanced sensitivity, improved control, and superior dynamic performance.

M.A.S™ Metal Acoustic Shield

The precision-machined metal housing acts as both a structural reinforcement system and resonance control mechanism.

This increases durability while minimizing unwanted vibration and coloration.

Quick-Lock Installation System

Q.F.M™ Quick Fix Mounting Technology

Unlike conventional tweeters that require multiple screws and mounting accessories, the AST-250 features a dedicated locking ring system.

The included mounting collar allows fast and secure installation without visible screws, reducing installation time while providing a clean factory-like appearance.

Benefits include:

• Faster installation
• Improved mounting stability
• Reduced vibration
• Cleaner visual integration
• Compatible with custom A-pillar and dashboard installations

Sound Performance

The AST-250 is tuned to deliver exceptional detail and smoothness throughout the upper frequency range.

Vocals gain greater air and articulation while cymbals, strings, and acoustic instruments are reproduced with outstanding realism.

The ceramic composite diaphragm maintains excellent control at high listening levels, allowing the tweeter to remain detailed and musical without becoming aggressive or fatiguing.

Whether used in active DSP systems or premium passive configurations, the AST-250 provides the refinement required for serious audiophile-grade car audio installations.

The ALCHIMIST AST-250 is a high-performance automotive tweeter featuring a Ceramic Composite Diaphragm, neodymium motor system, and precision metal housing. Engineered for exceptional detail, wide soundstage reproduction, and effortless installation, it delivers premium high-frequency performance for advanced car audio systems.
