TRANSAUDIO GROUP LAUNCHES ATC’S MOST COST-EFFECTIVE STUDIO MONITORS – THE SCM11s

scm11.JPGLAS VEGAS, NEVADA – JULY 2009: TransAudio Group has announced the immediate availability of ATC’s most reasonably-priced reference monitor – the SCM11 two-way passive speaker. The new monitor incorporates ATC’s innovative Constrained Layer Damping (CLD) technology, which reduces third-harmonic distortion between 100 Hz and 3 kHz, resulting in an extended, resonance-free axial frequency response, improved off-axis frequency response, and a significant increase in loudspeaker power response.

The new CLD technology is incorporated in the 5.9 inches (150 mm) mid/low frequency driver with 1.77 inches (45 mm) integral soft dome. The driver features a precision undercut bass pole, in-house, hand-wound precision flat wire coil, and a massive optimized motor assembly. The driver is paired with a new soft dome 0.98 inches (25 mm) neodymium high-frequency unit featuring a precision alloy ATC waveguide.

The frequency response of the SCM11 is 56 Hz – 22 kHz (-6 dB), with a sensitivity of 85 dB (1W @ 1 meter) and a maximum SPL of 108 dB. The recommended power amplifier rating is 50 to 300 Watts.

Finished in black ash, the cabinet dimensions are 14.96 inches (380 mm) (H) by 8.3 inches (211 mm) (W) by 9.84 inches (250 mm) (D). Each unit weighs 18.7 lbs. (8.5 kg).

The brainchild of ATC engineer Ben Lilly, Constrained Layer Damping was first introduced in the ATC SCM16A self-powered monitor. Previously, the only way to achieve an extended on-axis frequency response was to use a stiffer driver cone, but the unavoidable tradeoff was a poor off-axis frequency response and a colored sound due to multiple resonances. Traditional designs damp the cone’s motion to reduce these unwanted effects, but the result is a dramatically less efficient loudspeaker. Lilly’s innovation was to sandwich a constrained damping layer between two lightweight driver cones. The shear generated when the cone flexes results in less acoustic distortion by instead dissipating unwanted vibration energy as frictional heat. CLD reduces third-harmonic distortion by 10 – 15 dB between 100 Hz and 3 kHz, resulting in a better sounding loudspeaker that requires much less power to generate a given SPL.

“ATC’s low distortion technology really works but it’s pricey. This new CLD technology means that small affordable versions of the high-end speakers are now possible. The SCM11 is ATC’s most reasonably-priced loudspeaker to date, and we’re excited to be able to offer this kind of clarity at $1,440 a pair,” says Brad Lunde, president, TransAudio Group, Inc.
