ATC's new Super SH25-76S Soft Dome Tweeter

The SH25-76S is ATC's premium 25mm soft dome tweeter, designed and built with the same no compromise philosophy as all other ATC drive units and to perfectly compliment the renowned SM-75-150S Super Dome mid-range driver.

Unlike almost any other 25mm tweeter on the market the SH-25-76S is a dual suspension design which ensures pistonic motion, suppressing anhramonic rocking mode, even at high drive level, and enables the use of narrower magnetic gaps, this, along with a short coil, long gap configuration ensures unparalled lineraity and incredibly low distortion throughout its intended operating band. The soft dome diaphragm is based on a complex geometry which maximises power transfer from the former, extending the high frequency response and giving a smooth off-axis response.

The massive neodymium motor with heat treated top plate is optimised to give a 20,000 gauss (2.0 Tesla) in the magnetic gap, extending the frequency response well beyond 20kHz and resulting in moderately high sensitivity, even with the very strong, well-damped structures employed. The huge motor assembly also performs the secondary function of dissipating heat away from the coil and ensuring high power handling and low power compression. The motor topology and moving assembly design negate the requirement for ferro fluid. The SH25-76S is therefore, free from the detrimental effects of this drying out over time.

The geometery of the waveguide is designed for optimum dispersion and an extended on-axis frequency response. It is made from a precision machined alloy so that the entire structure is extremely rigid and free from resonances.

Specification-

Sensitivity: 91.5 +/- 0.5dB/W @ 1m

Nominal Impedance: 6 ohms

Frequency Lineraity (+/- 2dB): 1.5kHz to 22kHz

Cut-Off Frequency (-6dB): 26kHz

Dispersion: +/-80 degrees Coherent

Magnetic Gap Height: 3.0mm

Coil Length: 2.0mm

Magnetic Gap Flux Density: 2.0 Tesla/20,000 Gauss

Weight: 0.34kg

SCM45A calibration, measurement and QC.

In production ATC use a spliced nearfield measurement. The Mid and HF are measured over a short time window, essentially negating the effect of any room reflections, and the bass is measured over a longer time window to obtain the required resolution. The measured response can then be compared to a golden reference (measured in the same environment) and the mid and HF magnitude adjusted accordingly to ensure all loudspeakers leave the factory with the correct balance.

What Hi-Fi have reviewed ATC's new SCM40A Active monitors as part of their monthly ‘Temptations’ feature. Here is a little of what they had to say:
“these ATCs… take all in their stride, revealing a lovely cohesion throughout the frequency range. Resolution, timing and dynamics are all spot-on… factor in the built-in amplification, exotically engineered in-house drive units and the resultant exceptional sound quality, and the SCM40As emerge as something of a high-end bargain. Consider us smitten.” What Hi-Fi, March 2015. The April edition of the magazine that features the review is on sale now.

The curved SCM40A is an active version of ATC's highly successful curved SCM40 passive monitors. The 3-way design, employing all hand built ATC drive units is complimented with a built-in 235Watt class AB tri-amplifier. The MOSFET based amplifier is a modified version of that found in ATC's larger active monitors, the SCM50ASL, SCM100ASL and SCM150ASL.

New Cabinets and Systems

Establishing what is to be a new style for ATC’s most competitively priced range of loudspeakers, the new SCM19's benefit acoustically and aesthetically from a curved cabinet construction. Braced and laminated for high rigidity and damping, the curved enclosures in real cherry or black ash veneer also impart a strong impression of design quality. Improved crossovers featuring metallised polypropylene capacitors, large air cored inductors and ceramic wire-round resistors offer superior power handling and clarity. The SCM19 exhibit an impedance curve free from low values, presenting an easy load for amplifiers of 75 to 300 watts. The SCM19 is designed for optimum performance with the grill in place – although the difference in performance without the grill is minimal. The metal grille, finished in anthracite grey, fixes to the cabinet via hidden magnets. According to tradition, each model number represents internal cabinet volume in litres.

Second Generation SCM19

ATC’s SH25-76 soft dome tweeter is joined by the company’s highly linear 150mm mid/bass driver. It features an integrated 75mm soft dome – exceptional for its horizontal dispersion of mid-band frequencies – and a huge 9kg high-energy, ‘Super Linear’ magnet system, which includes a 75mm diameter flat wire, underhung voice coil, meticulously milled and formed by ATC. The magnet system and a carefully weighted doped fabric cone assembly contribute to the SCM19’s wide bandwidth, impressive dynamic range and convincing bass output coupled with very low distortion as a result of the unique ‘Super Linear’ motor system.

ATC MONITORS CLEARLY DEFINE JOE SATRIANI AND JOHN CUNIBERTI’S NEW “SHOCKWAVE SUPERNOVA” RECORDING (Transaudio Group)

Joe Satriani with ATC SCM25A and SCM300ASL Professional monitors

OAKLAND, CALIFORNIA – APRIL 2015: Engineer John Cuniberti’s first professional highlight was a gig mixing monitors for Stevie Wonder in the late 1970s. After that, he pivoted to the studio and has since recorded, mixed, and mastered hundreds of major- and indie-label artists, including The Dead Kennedys, Tracy Chapman, Thomas Dolby, and the Grateful Dead. Cuniberti worked with legendary guitar virtuoso Joe Satriani to record his first professional studio album, Not Of This Earth, in 1986, and the two have been a productive team ever since. Most recently, they traveled to Skywalker Sound and 25th Street Recording (Oakland, California) to cut tracks for Satriani’s forthcoming album, Shockwave Supernova. Given the tremendous success they had had with ATC SCM25A three-way active monitors in Satriani’s home studio, they rented a pair at both Skywalker and 25th Street.

“A little while back, Joe expressed growing frustration with the nearfields he had in his studio at the time,” said Cuniberti. “He felt like the mid-range was too forward and aggressive, and that led him to make decisions that didn’t translate outside of the studio. I recommended the ATC SCM25As, and he immediately fell in love with their musicality and the way the decisions he made in the studio translated elsewhere.” When Cuniberti arrived at Skywalker, he didn’t find any nearfields that he felt comfortable using, so he arranged to rent a pair of ATC SCM25As for the two weeks they had booked. Then the same thing happened at 25th Street Recording. “25th Street had massive ATC SCM300ASL and SCM150ASL soffit-mounted loudspeakers, which sounded great, but again… no nearfields I wanted to use,” he said. “Again, we rented SCM25As. Finally Joe decided to buy a pair from Sweetwater for himself.”

“Working with the ATC SCM25As at Skywalker Sound, at 25th Street Recoding, and at my home studio has been a wonderful experience,” said Satriani. “In all three environments, the sessions stayed accurate with imaging I could trust, and the individual tracks always came up clear, punchy, and transparent. The SCM25As are powerful yet precise sounding speakers, without the ear fatigue. Most importantly, it’s fun to create music on them!”

Cuniberti agreed: “We were able to spend time between the SCM25As all day, day after day, without getting stressed out. They sound great loud and have an impressive low-frequency response. Importantly, now that we’re listening back at home, everything we tracked at Skywalker and 25th Street sounds like I expected it to sound. There are no surprises. I think that’s the mark of an effective studio monitor. I think the industry has evolved to this point. You can go back to the NS-10 craze, which I think happened because everyone was so hungry for a stable reference point. Then some more truly transparent models started emerging, but the evolution of those modeled tended toward hype on the high end and hype on the low end. Sure, that makes a mix sound ‘good,’ but it burns the engineer out and leads to mixes that are flat and lifeless on other systems. In contrast, ATC’s professional division has remained committed to building monitors that will allow an engineer to work long hours without fatigue and with the confidence that the music will sound right everywhere else.”

ATC IMPROVES PERFORMANCE OF THEIR FLAGSHIP HI-FI SPEAKER SYSTEMS WITH THE INTRODUCTION OF THE COMPANY’S NEW ENHANCED ‘S-SPEC’ TWEETER

Building on the success of its hand-built standard tweeter, ATC has developed and manufactured an ENHANCED ‘S-SPEC’ VERSION for its flagship models.

After considerable development time the “S-SPEC’ tweeter completes the rollout of proprietary drivers across every ATC loudspeaker system. Six years in the making, the new SH25-76S design is a significant technical advance for ATC and a proud achievement for Managing Director Billy Woodman and R&D Manager Richard Newman. The Woodman/Newman collaboration has ensured that both the standard SH25-76 (as fitted to the Company’s SCM7/11/19/40/40A models) and ‘S-Spec’ SH25-76S tweeters exceed the exceptionally high levels of performance and consistency expected of an ATC driver.

ATC Super SH25-76S HF unit

The advent of the SH25-76S means that for the first time in a distinguished forty-year history, every ATC speaker system is able to benefit from complete ATC driver configurations, wholly designed and hand-built at the company’s UK development and production facility at Stroud, Gloucestershire. Now introduced on the Tower Series (SCM20/50/100/150), Anniversary Series (SCM50/100/150) and Classic Series (SCM20/50/100/150), the SH25-76S is ATC’s premium 25mm soft dome tweeter, developed with a no-compromise engineering approach in order to complement the renowned SM75-150S Super Soft Dome mid-range driver.

ATC Super SH25-76S HF unit & ATC SM75-150S Super Soft Dome mid range drive unit

ATC SM75-150S Super Soft Dome mid range drive unit

In common with the standard SH25-76 (but unlike almost any other 25mm tweeter on the market) the SH25-76S is a dual suspension design, employing both an upper and lower suspension.

The key benefits are:

• Suppression of enharmonic diaphragm/coil ‘rocking’ modes

• Assured pistonic motion

• A very narrow magnetic gap for unparalleled linearity and low distortion throughout its wide operating band

Further Key Design Features are as follows:

Improved Off-Axis Response: the complex geometry of the tweeter’s soft dome diaphragm and precision-machined, low-resonance alloy waveguide produces a smooth on-axis and improved off-axis response, which now extends beyond ATC ‘s previous benchmark of 22kHz to reach 25kHz (-6dB).

Stronger Magnetic Field: a massive neodymium motor complete with heat-treated top plate is FEA optimised to provide 20,000 Gauss (2.0 Tesla) in the magnetic gap (up from 15,000 Gauss in the standard SH25-76 unit).

Higher Sensitivity: higher sensitivity of 91.5 (±0.5 dB/W @1m) is achieved for the SH25-76S, despite the use of robust, well-damped mechanical structures.

Higher Power Handling, Lower Power Compression: shared by both standard and ‘S-Spec’ tweeter models, the short coil/long gap motor design and narrow magnetic gap perform the secondary function of dissipating heat away from the coil, ensuring high power handling and low power compression while liberating the structure from a reliance on ferro-fluid, which can dry out over time, compromising performance.

Commenting, R&D Manager, Richard Newman said, “We feel the new tweeter lifts the capability of our systems to new levels and reinforces our belief that exceptional system performance can only be achieved through exceptional transducer performance”.

For owners of certain older models wishing to upgrade, ATC tweeter upgrade kits are expected to roll out later this summer.
