Jason Kennedy reviews ATC's curved SCM11 passive monitors

http://www.hifiwigwam.com/stealthy-stand-mounts-offer-amazing-sound-atc-scm11/

Second Generation SCM11

The new SCM11 features ATC’s SH25-76 with an ATC CLD 150mm mid-bass driver incorporating a 45mm soft dome. Constrained Layer Damping is a driver cone technology exclusive to ATC and represents a step-change in driver-to-system performance. Advantages include reduced harmonic distortion between 300Hz and 3 kHz, an extended frequency response that eases constraints on the crossover filter slope, and improved off-axis response.

SH25-76 Tweeter

Sharing technology with the renowned ATC soft domed mid-range drive unit, the new tweeter employs a unique dual suspension system suppressing rocking modes even at high power output levels. The ATC configuration of a short edge-wound voice coil in a long, narrow magnetic gap ensures exceptionally low distortion throughout its operating band and removes the need for ferrofluids, which can dry out over time, compromising performance.
A complex, shaped, soft-domed diaphragm extends high frequency range and offers a smooth off-axis response. The tweeter’s 15,000 gauss (1.5 tesla) neodymium magnet has a black heat-treated top plate, which dissipates heat away from the voice coil to maintain high power handling and low power compression. A precision-machined 5.5mm rigid alloy waveguide provides optimum dispersion, a flat on-axis frequency response and resonance-free operation.

ATC's new SCM20SL MK2 Passive monitors

Got a great amp already? Introducing the new ATC passive SCM20SL MKII loudspeakers. Maintaining the strict performance criteria of ATC reference monitors, the SCM 20SL MKII offers project and home studios the dynamic range and pristine imaging ATC is known for worldwide.

Designed to fit within the company's highly-regarded line of speakers, the ATC "Passive 20" features the same ATC built woofer and tweeter as the active (SCM20ASL) version of the speaker. The SCM20SL MKII passives are housed in a conventional "pro-black" box for easy placement on any meter bridge.

ATC recommends amplifiers with at least 200W per channel of power. The Passive 20 loudspeaker enables ATC speaker fans to own a high performance monitor at half the price of the actives.

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. The woofer magnet assembly utilizes ATC's unique "SL" technology to greatly reduce third harmonic distortion and reveal mistakes and details. The tweeters are ATCs new dual suspension high powered tweeters. They do not use ferro fluid for cooling so will last a lifetime. A newly redesigned crossover ensures a smooth transition across all frequencies. All ATC drivers are manufactured in-house to exacting tolerances and are legendary for their many design innovations.

The Absolute Sound reviews ATC's curved SCM19 passive monitors

http://www.theabsolutesound.com/articles/atc-scm19-loudspeaker-1/


Featuring the new ATC designed and built 25mm soft dome tweeter, updated bass/mid drivers and crossovers housed in a curved, laminated cabinet, the first of a new range of ATC closed-box passive loudspeakers has arrived. The second generation SCM19 employs ATC’s landmark SH25-76 tweeter, developed to satisfy the company’s long-established rigour in drive unit engineering.

SH25-76 Tweeter

Sharing technology with the renowned ATC soft domed mid-range drive unit, the new tweeter employs a unique dual suspension system suppressing rocking modes even at high power output levels. The ATC configuration of a short edge-wound voice coil in a long, narrow magnetic gap ensures exceptionally low distortion throughout its operating band and removes the need for ferrofluids, which can dry out over time, compromising performance.

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.

Technical data for 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

Hi-Fi Choice review ATC curved SCM40 passive monitors

http://www.atcloudspeakers.co.uk/wp-content/uploads/2014/09/HiFi-Choice-Oct-2014-ATC-SCM40.pdf

Second Generation SCM40

The new SCM40 features ATC’s new SH25-76 tweeter with a ATC’s renowned 75mm/3” Soft Dome mid-range and a 164mm, short coil – long gap (underhung) bass driver. The three-way design and inclusion of the Soft Dome mid results in excellent clarity, even at high drive levels with bass heavy souce material. It also gives wide, even dispersion resulting in excellent stereo imaging and un-fussy positioning in the home. The new model also benefits from crossover revisions that have improved the loudspeakers overall balance and the integration between mid and high frequency elements.
