Engineering-Led Design
​
High performance comes not from individual components alone, but from careful integration.
Cabinets, internal wiring, crossovers and transducers are each high performance in their own right, but are optimised for integration - both within the loudspeaker system and in the electrical interaction with the amplifier, producing a superior overall sound.
​
Cabinet Design
​
Enclosures are shaped to reduce internal reflections and standing waves to preserve time and amplitude integrity of the music signal. This ensures exceptionally clean spectral decay, preserving the natural stop-start behaviour fo live instruments.
Enclosures are made from 24mm thick Baltic Birch hardwood ply with extensive internal bracing, strategically positioned through structural analysis. This ensures the cabinets are structurally inert, preserving purity of sound.
​
Internal Wiring
​
Binding posts are made from non-magnetic materials to avoid eddy currents. This is crucial in preserving electromagnetic linearity because eddy currents are a form of electrical inertia that introduces signal distortion in the time domain.
​
British made, 99.9999% pure copper cables are used for internal wiring. These multi-strand cables are configured to minimise EMI (electromagnetic interference) and RFI (radio frequency interference), thus minimising noise.
​
Crossover Design
​
Crossovers are optimised to minimise phase differences between transducers in both the crossover region (the transition band) and the pass band regions. This is achieved using computational simulations based on precise electrical and acoustic measurement. This is crucial for preserving both tonal accuracy and transient integrity.
Crossovers are also optimised for a relatively flat impedance curve. In other words, Morgan Acoustics Loudspeakers do not present amplifiers with a 'difficult load'. This is particularly beneficial in ensuring consistency of sound regardless of amplifier choice.
​
High Frequency Transducers
​
An air motion transformer (AMT) is used for the reproduction of the highest frequencies. This design offers three key advantages. The first is, it allows for an ultra-light and non-resonant diaphragm. Additionally, due to the arrangement of the permanent magnets relative to the electromagnet diaphragm, the electromagnetic force is highly linear when compared to a conventional dome tweeter or ribbon. Finally, since the entire moving membrane is magnetised, there is no reliance on a stiff membrane - this means there are no diaphragm breakup modes that are associated with dome tweeters. This results in extremely high dynamic range and low harmonic distortion which translates to a fast, detailed, non fatiguing sound.
​
The AMT diaphragm is also recessed in the cabinet such that the acoustic centres of the drive units can be closely aligned - this ensures phase alignment across transducers, crucial to both tonal accuracy and dynamic integrity.
​
Bass and Midrange Transducers
​
Drive units are built to Morgan Acoustics proprietary specifications with the goal of reducing all forms of distortion such as harmonic distortion (THD), intermodulation distortion (IMD) and dynamic compression.
​
Midrange and bass drivers both benefit from design features that minimise eddy currents, thus preserving the linearity of the magnetic field. This reduces both harmonic and intermodulation distortion, ensuring precise tonal accuracy of instruments.​​
​
Bass drivers have long linear stroke to ensure the force driving the diaphragm remains in proportion to the input signal even at high excursions. This ensures linearity during transient peaks, preserving the dynamic range of transients.
