ATC, Acoustic Transducer Company, is a legacy British loudspeaker manufacturer that was established in 1974 for the professional recording industry. ATC Loudspeakers are known for their ultra-low distortion, pure, clean and accurate sound reproduction critical in creating a superior recording.

They are used by hundreds of award-winning recording artists, such as Pink Floyd, Lenny Kravitz, Diana Krall, James Newton Howard, Tom Petty and Mark Knopfler. They can be found in a long list of world-renowned recording studios such as Blackbird Studios in Nashville, East West Studios in LA, House of Blues in Nashville/LA and Sheffield Labs Founder Doug Sax’s Mastering Room.

WHAT MAKES ATC SPEAKERS UNIQUE?

ATC speakers are 100% handcrafted and vertically integrated; every component, from voice coil to driver to crossover to amplifier, is hand-designed and built by ATC, which results in a superior acoustic design that delivers near perfect reproduction of music or movie sources. The factory is located in the Gloucestershire area of the UK.

Active Amplification

Active Vs Passive – What are the benefits of an active loudspeaker system?

While it is possible to design a high performance loudspeaker using passive components, an active design has a number of benefits, these are listed below;

1) More accurate crossovers

  • Active filters allow independent control of level and phase(time).  This is not possible with passive crossovers.  With a passive crossover any changes you make to the circuit affect both level and phase.  The benefit this allows is that we can adjust for the crossover to have a perfect magnitude response and phase response.  The result is that the stereo imaging is much more stable and the tonal balance of instruments is improved.
  • An active filters performance is not changed by the temperature of the drive unit voice coil as they are not directly connected to them.  A passive crossovers performance (filter shape and crossover frequency) will change with voice coil temperature which, increases with SPL (input power).  This leads to passive loudspeaker systems having a slightly different sound when driven at low SPL compared to high SPL.  The performance of active ATC systems changes very little with drive level.
  • More efficient crossovers.  Active crossovers do not need to use series inductors to achieve their filter shapes.  Series inductors have resistance that reduces bass driver efficiency and also increases the Q of the low frequency tuning.
  • More cost effective crossovers.  Passive crossover networks use large, bulky and expensive components in order to deal with the high voltages from a power amplifier.  Active crossovers offer better performance for lower cost.

 

2) Lower Intermodulation-Distortion

As the separate amplifiers in an active system are located after the crossover, they only operate over a limited bandwidth.  This reduces intermodulation-distortion and, in comparison to a passive system, even a bi or tri-amped passive system, an active system will show 15 – 20dB lower intermodulation distortion.

 

3) Improved Frequency Response and Stereo Matching

An active system can very simply feature individual gain trims for the two, three or four amplifiers involved.  This allows very simple fine tuning of the frequency response and the stereo matching.  Similar matching in a passive system would involve the replacement of large, soldered passive components which, in practice, is difficult and time consuming for the manufacturer.

 

4) Lower Cost for Higher Performance

Because an active system is designed, engineered and implemented by a single manufacturer into as compact a package as the design allows, cost is saved on electronics case work and packaging and the manufacturer can invest in real performance enhancing changes or pass the saving on to the customer.
