HEDD Type 20 MK2 Speaker Review
For those in search of a compact yet powerful 3-way speaker, the HEDD Type 20 MK2 might be just what you need. With cutting-edge technology, versatile features, and a focus on precision, these speakers cater to modern demands for accurate sound reproduction.
A Legacy of Innovation: Air Motion Transformers
The HEDD Type 20 MK2 is a nearfield, 3-way speaker designed for desktops and meter bridges. Equipped with a 7” honeycomb woofer, a 4” honeycomb mid-range driver, and HEDD’s Air Motion Transformer (AMT), it boasts a frequency range of 32Hz to 40kHz.
Klaus Heinz, founder of HEDD Audio and ADAM Audio, studied with physicist Oskar Heil, who pioneered the AMT. Klaus refined this technology, creating a driver with a 4:1 air-moving efficiency ratio compared to a standard ribbon tweeter’s 1:1 ratio. The result? Fast transient response, low distortion at high volumes, and remarkable detail.
Crossovers at 250Hz and 3200Hz ensure each driver operates within its optimal range, contributing to the dynamic range and dispersion benefits of 3-way speakers over 2-way designs.
Precision Timing with The Lineariser
One of the standout features of the HEDD Type 20 MK2 is its Lineariser, powered by a 32-bit, 96kHz SHARC digital signal processor. This zero-phase filter aligns the timing of the bass, midrange, and treble drivers, resolving phase discrepancies that can otherwise degrade clarity.
The Lineariser enhances the phantom centre, stereo imaging, and transient detail, creating a soundstage that feels focused and precise. While the 10ms latency introduced might be a concern for live monitoring, the improvement in mix translation is a significant advantage for studio work.
Reflex Port: Open or Plugged?
The HEDD Type 20 MK2 offers a reflex port design with the flexibility to plug the port, altering the bass response. An open port delivers extended, harmonically rich low frequencies, while a closed port offers tighter bass and reduced extension.
The speaker has an inclusion of a reflex port that can also be plugged with a detachable screw used to insert or remove the plug. A selector switch on the back of the speaker alters the speaker performance according to each setting.
This graph compares ported and sealed speaker designs based on SPL versus frequency. Ported designs enhance low-frequency output, delivering powerful, extended bass at the expense of precision. Sealed designs, by contrast, provide tighter, more controlled bass but with less low-end extension, ideal for accuracy. HEDD further enhances flexibility with a bass extension mode for deeper sub-bass, high and low shelving filters, and an 80Hz high-pass filter for subwoofer integration. With a maximum SPL of 120dB, these speakers deliver exceptional clarity even at extreme volumes, making them versatile for various applications.
Desk Reflection Filters
Desk reflections can degrade audio quality by introducing comb filtering and phase issues. The HEDD Type 20 MK2 includes desk reflection filters for small, medium, and large desks, applying reductions of -1dB, -2dB, and -4dB respectively at 180Hz. While effective, offering additional frequency options could enhance their versatility in addressing room-specific challenges.
Connectivity: Analogue and Digital
The HEDD Type 20 MK2 supports both analogue XLR and AES digital connections. Using AES allows you to bypass additional D-to-A and A-to-D conversion stages, preserving signal purity for a more accurate listening experience.
Exceptional Sound Quality
These speakers deliver an expansive stereo field, strong phantom centre, and impressive depth, making audio seem to float in the air rather than originate from a point source. The Air Motion Transformer ensures fatigue-free listening even during extended sessions.
The tonal balance is enjoyable for both mixing and casual listening, though the upper midrange can become sharp at excessive volumes. Overall, the clarity and detail offered by the Type 20 MK2 make it a standout choice.
Price and Value
At approximately £4000 per pair, the HEDD Type 20 MK2 is an investment, but one that delivers exceptional quality. Compared to speakers in the £1000–£1500 range, they represent a noticeable upgrade, especially for producers and mix engineers seeking precision and versatility.
Auditioning speakers in your own studio environment is crucial, as room acoustics greatly influence performance. Many reputable dealers, such as SX Pro Audio in the UK, offer home trials to ensure you make an informed choice.
Final Thoughts
The HEDD Type 20 MK2 combines innovative technology with practical features, making it an excellent option for professionals aiming to elevate their audio production. Whether you’re a seasoned engineer or an aspiring producer, these speakers deserve a place on your shortlist.
