ASTON DOWN, GLOUCESTERSHIRE, UK: ATC is proud to announce upcoming availability of the SCM25A Pro Mk2 as a compact, three-way, high-performance active monitor — maintaining the core of its popular predecessor from which it evolved while refining key areas of design and performance, including replacing the original SCM25A Pro’s OEM (Original Equipment Manufacturer) high-frequency driver with the specialist British manufacturer’s own ‘S-SPEC’ SH25-76S premium soft-dome, dual-suspension tweeter developed with a no-compromise engineering approach (as fitted to the two-way SCM20A Pro and larger, three-way SCM45A Pro, SCM50A Pro, SCM100A Pro, SCM110A Pro, and SCM150A Pro models since 2015) — as of February 20… Formed in 1974 by Billy Woodman to manufacture custom drive units for the professional sound industry, then evolving to produce its own ranges of loudspeaker systems and partnering electronics, ATC as a company clearly has history. Having said that, so does its perennially popular SCM25A Pro compact nearfield monitor — making its presence seen and heard as a valuable tool in studios the world over since its release in 2010 and a product development process that started with key clients in 2008. “Over the past 13 years, the SCM25A Pro has proven to be both exceptionally popular and a valuable tool in the modern studio,” says ATC Technical Sales Manager Ben Lilly. “However, we knew we could make improvements to performance, and also offer improved consistency with the rest of the Pro product range while ensuring that we had greater control of the manufacturing process.” ATC announces SCM25A Pro Mk2-unnamed-2-.jpg As a compact, three-way, high-performance active studio monitor, the SCM25A Pro Mk2 is based around a 6.5”/164mm bass driver loaded in a ported/ vented enclosure, tuned to 32kHz and featuring a 3”/75mm diameter port with flared entry and exit to minimise port air noise. Needless to say, its killer combination of exceptional mid-range clarity; high-output, extended bass response; and modest 25-litre/0.9 cubic foot size make it ideal for nearfield monitoring across a wide range of critical applications. All new to the SCM25A Pro Mk2 is its high-frequency driver, ATC having replaced its popular predecessor’s OEM part with its own ‘S-SPEC’ SH25-76S, manufactured in-house with a no-compromise engineering approach (as fitted to the two-way SCM20A Pro and larger, three-way SCM45A Pro, SCM50A Pro, SCM100A Pro, SCM110A Pro, and SCM150A Pro models since 2015). This driver is a 1”/25mm soft-dome design, handling high frequencies above 3.5kHz, but, unlike almost any other 1”/25mm tweeter on the market, it employs both an upper and lower suspension to better support and control the coil and dome motion. This, therefore, makes for a narrower magnetic gap, resulting in higher magnetic flux, which, in turn, extends the high-frequency response and reduces 3rd harmonic distortion. As ATC R&D Manager Richard Newman notes, “We feel the new tweeter lifts the capability of the SCM25A Pro Mk2 to a higher level, retaining the outstanding balance of the monitor, but extending the high-frequency response and reducing distortion to really help lower-level detail in the high-frequency band cut through. This will greatly aid faster decision-making and outstanding translation outside of the studio.” Meanwhile, mid-band frequencies between 380Hz and 3.5kHz are handled by ATC’s acclaimed 3”/75mm soft-dome mid-range driver, duly combining high-efficiency, high-power handling, low distortion, and wide dispersion characteristics to ensure class-leading performance for the SCM25A Pro Mk2 in this critical frequency range. As a mainstay of ATC’s Pro product range, this component features in eight models, making certain consistency spans from nearfield through to main monitors. Mid- and high-frequency elements are supported by a 6.5”/164mm proprietary bass driver that takes care of the SCM25A Pro Mk2’s low frequencies below 380Hz. This features a carbon-loaded paper cone while the driver motor employs a short-coil operating in a long magnetic gap, helping to minimise distortion generated by drive force modulation. Additionally, a large 2”/50mm voice coil and generous excursion capability ensure outstanding dynamic range. Rear-mounted, a three-way class A/B amp — termed Tri - AmpPack in ‘ATC-speak’ (as clearly highlighted on the rear panel itself) — actively drives the SCM25A Pro Mk2 with each drive unit having its own dedicated power amplifier. Audio balanced input is via a rear panel-mounted three-pin XLR and power is via an IEC (International Electrotechnical Commission) mains power inlet. Input sensitivity and Bass boost controls are also accessible to the user. Ultimately, crossovers are 4th order Linkwitz-Riley and all-pass filters are included to optimise the phase response through the crossover regions, improving the tonal quality and imaging, as well as on- and off-axis frequency response. Furthermore, FET (Field-Effect Transistor) peak limiters are included to reduce amplifier ‘hard-clipping’, while POWER/LIMIT is indicated — ‘on’ and ‘active’ — by a front panel-mounted bi-colour LED. It is also worth mentioning that the amplifier is designed and manufactured in-house, just like the speaker drive units. All are well worthy of a specialist British loudspeaker drive unit and complete sound reproduction system manufacturer that clearly has history. ATC’s SCM25A Pro Mk2 compact, three-way, high-performance active studio monitor is available as of March 1, 2023 (country-/region-dependent), when it will retail in the UK for £7,075.00 GBP (plus VAT) per (left- and right-orientated) pair.

I've already bought some spare tweeters and put them away in a draw!
The OEM Vifa tweeter is discontinued!!
ATC had no choice but to rebox the 25's into a slightly bigger box and fit their own proprietary tweeter.
Ironically, I prefer the Vifa tweeter to the ATC one, though I could live with their tweeter in a pair of 50's :-)
One other point - the 25's were never very pretty, but I have no idea what ATC have done to the front panel of the MK2's
they're covered in bolt heads - it looks awful - a very strange design decision, I mean is wasn't like the front panel was about to fall off!!

Yeah I agree they don’t look pretty by any means, but I’m also surprised they didn’t design a new tweet to be pretty much a drop in replacement for the Vifa. Of course the question is since the whole ATC model number system is based on internal cabinet volume is this really a 25 mK ii?
If I had a pair of original 25’s I would get a pair of replacement tweets while I could!

You'll never recoup the money unless you're overpriced for today's music market or you run a commercial facility and will save money in the long run from the ATCs not blowing up as quickly.
Otherwise, if you're not expecting to make money or work for social media influencers who sell vinyl records as knickknacks... go for it.

NS-10’s will blow a woofer if you’re a moron and blast them, but everybody I know fuses the woofs. So - what gives with the fear of blowing monitors? Are people doing this on a daily basis? I can’t think of a single engineer I know that listens that loud anymore. Am I living in a different world or am I just completely out of touch these days? |

It’s not usually playing loud, crappy amps with little or no protection, DC, things that go wrong somewhere ahead of the amp. Leaky caps in a crossover, bad QC of drivers, physical damage to drivers ( ever seen a 15 in JBL with the magnet no longer aligned after being dropped). Fuses and breakers are great protection from long term over power, but are pretty useless from most of the common quick faults. |

Inside was an amp of far less quality than the price tag might of suggested. Mostly SMC on a single board and not that neatly put together! I’m hoping, fingers crossed, in my ATC 25’s the class A/B MOSFET amp constructed with discrete components will serve me better and most significantly will be and remain serviceable by ATC. As opposed to Sennhesiers instructions to (I paraphrase) throw my 0300’s in a skip and buy a pair of 0310’s …. I’ll be forever annoyed with Sennhesier for refusing to release the schematic to my tech! That said, having bought into the ATC brand on the basis of their famed service history (repairing units sold in the last 70’s!) I’ve already had my first wobble in that I had to rapidly get on line and buy a few OEM VIfa tweeters (at ATC’s suggestion I may add) to ensure I don’t get landed with a 8K door stop for the sake of a $20 tweeter. Though I guess one expensive option would be to have my pair reboxed in the case that takes the new tweeter, I can see that being a solution for some down the line. |

At least they told you the OEM model and you can still get them!! If anyone is looking for sources, Madisound, Parts- Express, Solen, & Meniscus Audio. |

This is the link to the correct part number ATC gave me. www.digikey.co.uk/en/products/detail/peerless-by-tymphany/D26NC56-06/6557409Be careful as some people are selling the earlier model ending NC55 as opposed to NC56 and you would need to check with ATC if the earlier model is compatible. I got in there quick as Digi-Key are now sold out - they sold 45 tweeters in about 8 hours after the mk2 was announced! The tweeter is discontinued, but I’m sure there’s more out there and DIGI-KEY might get more stock from Peerless who probably still have stock. I toyed with buying up 40 of them but decided it was unfair to my fellow 25 users …. reminding me once again why I went into music as opposed to becoming a ruthless business man Also, I imagine ATC themselves will have a fairly large stock of their own so they can service 25’s way into the future, but of course a Vifa tweeter from ATC is going to be way more expensive because …. they are business men!! |
