![]() ![]() 75mm integral soft dome for wide and even midrange dispersion.Super Linear Magnetic System low distortion.ATC's Super Linear 195mm midbass driver.Improves the off-axis frequency response, and, if all that weren't enough, causes a huge increase in loudspeaker power response. Thus, ATC's CLDĭesign reduces harmonic distortion between 300Hz - 3kHz, creates an extended resonance-free axial frequency response, Shearing causes unwanted vibration energy to dissipate as frictional heat, instead of as acoustic distortion. Sound was virtually either acoustically compromised or inefficient.ĬLD is dramatically more efficient than conventional damping because of the way it shears when the cone flexes. Thus,Įvery loudspeaker that has ever been designed in the genre in the history of amplified TheĬonventional "fix" is to damp the motion of the driver cone, but this makes the loudspeaker dramatically less efficient. However, it comes at a price: a poor off-axis frequency response and multiple resonances that color the sound. 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.Ĭonventional loudspeaker design recognizes that stiff driver cones generate a desirable extended on-axis frequency response. Constrained Layer Damping is a driver cone technology exclusive to ATC and represents a step-change in driver-to-system performance. The new SCM11 and SCM12 Pro feature the ATC 195mm CLD midbass driver incorporating a 45mm soft dome. die-cast aluminum chassis, vented below spider.45mm integral soft dome for wide midrange dispersion.The motor topology and moving assembly design negate the It is made fromĪ precision machined alloy so that the entire structure is extremely rigid and free from resonances. The geometry of the waveguide is designed for optimum dispersion and an extended on-axis frequency response. The high frequency response and giving a smooth off-axis response. The soft dome diaphragm is based on a complex geometry which maximises power transfer from the former, extending This, along withĪ short coil, long gap configuration ensures unparalleled linearity and incredibly low distortion throughout its intended operatingĪTC Dual Suspension ‘S-Spec’ tweeter exploded view Unlike almost any other 25mm tweeter on the market the SH25-76S is a dual suspension design which ensures pistonic motion, suppressing anharmonic rocking modes, even at high drive levels, and enables the use of narrower magnetic gaps. Other ATC drive units and to perfectly compliment the renowned SM75-150S Super Dome midrange driver. The SH25-76S is ATC's premium 25mm Dual Suspension ‘S-Spec’ tweeter, designed and built with the same no compromise philosophy as all precision-machined 5.5mm rigid alloy special waveguide designed for optimum dispersion and an extended on-axis frequency response.2.0 tesla (20,000 Gauss) huge neodymium magnet.‘S-Spec’ short coil/ long gap voicecoil system, dual suspension system, no ferrofluid.1" complex geometry soft-domed diaphragm.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.Ī precision-machined 5.5mm rigid alloy waveguide provides optimum dispersion, a flat on-axis frequency response and resonance-free operation.ĪTC 25mm Dual Suspension ‘S-Spec’ tweeter 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.ĪTC Dual Suspension tweeter exploded viewĪ complex shaped, soft-domed diaphragm extends high frequency range and offers a smooth off-axis response. 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. precision-machined 5.5mm rigid alloy waveguide.1.5 tesla (15,000 Gauss) neodymium magnet.short coil/ long gap voicecoil system, dual suspension system, no ferrofluid.1" complex shaped, soft-domed diaphragm.ATC 25mm Dual Suspension Soft Dome tweeter
