Both the mid-bass driver and tweeter are handmade by ATC. The bass driver is a 6"/150mm part with huge 3"/75mm voice coil and massive, long-gap (short-coil) motor assembly featuring ATC's proprietary 'SL' motor technology. The tweeter is a 1"/25mm soft-dome part featuring a dual-suspension and very high energy 2.1 tesla motor. Together, they form the basis for an exceptional 2-way monitor loudspeaker.
Integrating the drivers is a 2nd order crossover featuring oversize air-core inductors which are wound in-house by ATC. Capacitors are all high voltage polypropylene film types which deliver outstanding reliability and minimal losses.
The SCM20 cabinet is constructed to be heavy and inert, with bitumastic damping panels deployed at critical positions to minimise cabinet colouration. The cabinets are available in 10 different hand selected veneers; satin black/white painted finishes and also piano/white high gloss polyester.
The passive SCM20 are ideally paired with ATC pre/power/integrated amplifiers. However, thei...
Brand highlights
Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:

The design of the AN-J Loudspeaker, by contrast, follows an altogether different philosophy. It calls for a cabinet that complements the chosen drive units, rather than fighting against them. Instead of trying to kill the resonances, we tailor the cabinet to place them in frequency bands where they aid and enhance the operation of the drive units, culminating in a loudspeaker system that makes the most of the preceding amplifier’s output. The material choice for the cabinet is an area where a great deal of research and development has taken place. Over the years, we have tried many different materials and combinations, a time consuming endeavour culminating in the current design, which utilises the highest quality birch ply for the entire cabinet. Bracing and internal damping is kept to a minimum and strategically applied to help, not hinder the drivers.
Our summary
Product Strengths
- Solid bass performance for a speaker of its size
- Able to do justice to any genre of music and at realistic volume levels
- Very easy to drive
- Offers a balanced presentation from top to bottom with seamlessness between the woofer and tweeter
- Started sounding like far more than a pair of 8″ two-way monitors when properly positioned along the side walls
Product Considerations
- Achieving the best imaging and deep bass may require experimenting with toe-in and distance from corners and the back wall
- Does not provide much forward/backward information, with the image typically stopping at the outer edge of the speakers
- The basic 'D' model comes only in black ash veneer, while higher-end models offer more choices
- Bass can be overblown if not adjusted properly in room placement
Comparisons (according to reviewers)
- The AN-E has more bass, is easier to drive, and has a bigger presentation
- Some may prefer the J because they find it a more taught presentation in the mid bass, as well as more "present" in the voice band
Takeaway:
The AN-J is a near full-range loudspeaker capable of articulation and organic flow, making music sound natural and engaging. If someone is looking for a communicative quality that remains consistent wherever they listen, then the AN-J could be a good fit.
