Key Benefits You’ll Love

Ultra-Wide Frequency Response

Extends up to 90kHz: Captures the full harmonic richness of high-resolution formats like SACD, DVD-A, and vinyl, while enhancing CD, MP3, and streaming audio.

Handcrafted Quality

Bespoke cables made with precision for audiophile-grade performance.

Deep Cryogenic Treatment (EDCT)

The copper conductors undergo Enhanced Isolda Deep Cryogenic Treatment, which enhances transparency and neutrality, outperforming other materials in clarity and detail. Improved Soundstage and Detail: Users report a larger soundstage, precise instrument placement, and enhanced detail, with the ability to discern subtle differences in recordings, such as identifying distinct recording studios. The cable excels in bass extension and dynamic range.

Signal Interference:

The design reduces capacitance (25pF) and inductance (0.5uH), minimizing signal loss and interference, which contributes to its clean and vivid sound.

Optimal Placement


Position at ear level, ideally on top of speakers, aligned with the front baffle. Fine-tune forward/back and secure with putty to minimise vibrations.
Piggyback Wiring
Connect the 1.5m cables (red to red, black to black) in parallel to speaker binding posts. Adjust the 6-position switch (74–89 dB) to match your speakers, starting low to prevent sharp treble.
Final Touch
Set the level and position, then experience the magic.

Townshend Maximum Supertweeter Sensitivity Setting Chart

Sensitivity Setting Chart

The Townshend Audio Maximum Supertweeter features a six-position sensitivity switch to match your speakers’ efficiency, ensuring seamless integration for a spacious, natural soundstage. The graph above outlines six settings (74–89 dB) to fine-tune high-frequency output (6–90 kHz) by ear, unlocking the hypersonic effect. Many prefer setting 2 for balanced clarity, while others choose 6 for vivid highs—find the magic point to capture the original recording’s depth and feel, as The Ear notes: “The stereo image reaches far beyond the loudspeakers.” 

The Science Behind the Townshend Maximum Supertweeter

The Maximum Super Tweeter leverages this science with its ultra-light ribbon diaphragm, which responds exponentially faster than heavier dome tweeters. This rapid transient response ensures precise reproduction of the leading edge of every note, eliminating time smear and delivering a relaxed, natural soundstage. As Max Townshend explains, “Even though a CD cannot produce information above 20kHz, Maximum Supertweeters make the format sound more natural and reveal a wealth of extra detail

Why Super Tweeters? The Science of Sonic Perfection

Human hearing is traditionally limited to 20kHz, so why extend frequencies to 90kHz? The answer lies in the physiological and psychological impact of ultra-high frequencies. Research, including studies like Human Ultrasonic Speech Perception (M. L. Lenhardt et al., 1991), suggests that ultrasonic frequencies contribute to a sense of naturalness and immersion, even if they’re beyond conscious perception. These frequencies enhance the harmonic structure of music, making instruments sound more lifelike and dynamic.

Lightning-Fast Precision: The Unrivaled Speed of the Maximum Super Tweeter

The Maximum Super Tweeter leverages this science with its ultra-light ribbon diaphragm, which responds exponentially faster than heavier dome tweeters. This rapid transient response ensures precise reproduction of the leading edge of every note, eliminating time smear and delivering a relaxed, natural soundstage. As Max Townshend explains, “Even though a CD cannot produce information above 20kHz, Maximum Supertweeters make the format sound more natural and reveal a wealth of extra detail.”

Perfect for Any System

Designed to integrate with all high-quality speakers, the Maximum Super Tweeter is a versatile upgrade. Its small footprint and included brackets for Quad electrostatic speakers make it ideal for both modern and classic setups, including:
Boxed speakers: Transforms their soundstage for a more immersive experience.

Electrostatics like Quad ESL-57s: Complements their natural roll-off with precise high-frequency extension.

High-efficiency horn systems: Adjustable settings ensure compatibility with sensitivities up to 110dB.

Setup is straightforward: place the super tweeters centrally atop your speakers, connect the provided cables, and adjust the sensitivity switch to suit your system. Experiment with settings to find the sweet spot—most users settle between levels 2 and 4 for optimal balance.
