Treble is of a decent quality, it’s just that the 4/5’s are particularly smooth. It’s not that the ATC’s are rough sounding – they’re really well balanced and neutral. The 4/5’s are just as detailed, but smooth rough edges a bit, and the soundstage (and details) stand a bit further back, meaning they are a more comfortable, inviting listen. So in essence, they are less forgiving on brighter, rougher recordings. That extra, precise detailing in the mids can be a bit tiring and the treble is subtly more pronounced and less silky than the 4/5’s. However, the ATC’s are also somewhat more forward. Lastly, I’d say they have a more solid-sound, in the sense of no cabinet coloration. Little intricacies pop out of the mix, which can be surprising at times. They also pick out and project a bit more detail across the frequency range, most noticeably in the mids. Still, it’s quite amazing how big and authorititive the 4/5’s sound in comparison (say 90%), despite being half the cabinet volume.

Not much deeper, but noticeable all the same. Like the 4/5’s in terms of articulation, tightness and integration, but they dig a little deeper.

I’d say the ATC’s have three main advantages. So again, for the sake of curiosity, I thought a home demo was sensible. As many here are probably aware, the 11's and 19's are the "non-pro" versions of the 12's and 20's - but I've only heard the 12's and 20's.Bit of a tangent, but to compare them against another speaker, I also had a home demo of ATC SCM11 over the weekend, as when I bought the 4/5’s (following a store demo), the ATC’s were a very close runner up at the time. However, I also have the SCM12 passives, which are very good, but are not in the same league as the 20's. No - those are too expensive for me, and too large for my studio (I compose and record), unfortunately. From what I've read, the active versions are generally considered to be better than the passives! But that's a lot of money there, and, I'm only relaying the opinions of mixing engineers, not of audiophiles. There's more vitality and clarity to the sound of the 20's, and they are of higher build quality.
#Atc scm11 version 2 drivers
All ATC drivers are manufactured in-house to exacting tolerances and are legendary for their many design innovations."Īs an aside, in my experience, the 20's are better than the Neumann KH310's, even though they do not dig as deep.

A newly redesigned crossover ensures a smooth transition across all frequencies. They do not use ferro fluid for cooling so will last a lifetime. The tweeters are ATCs new dual suspension high powered tweeters. The woofer magnet assembly utilizes ATC's unique "SL" technology to greatly reduce third harmonic distortion and reveal mistakes and details. "The SCM20SL Passive low-frequency section is a hybrid design incorporating a 150mm bass cone with a grafted 75mm soft dome for mid-range assist. Marketing says (you've probably already read this): The 20's do approach/approximate a 3-way design. As many here are probably aware, the 11's and 19's are the "non-pro" versions of the 12's and 20's - but I've only heard the 12's and 20's.
