SCM50ASLT : 3-way active
Stereomojo SCM50ASLT Review
“how do they sound? In a word, utterly truthful”
"faithful to the original"
"Instruments leap from the speakers unfettered by background noise"
"Needless to say, the Active 50’s will rock all night long. But they will also “classical” all night long as well"
Why Are Actives BEST?
Because the drive units have been precisely tailored to perfectly match the internal amplifiers, just as the amplifiers have been to match the drive-units. (compared to a passive speaker which has a general design because it is not amplifier specific & vice versa)
There is an amplifier per drive-unit and an active filter. (compared to a passive filter which is energy inefficient even when speakers are bi-amplified)
ATC 3 Way Active speakers
: drivers are manufactured in house to exacting tolerances and are legendary for their many design innovations. For instance,our hand-wound short voice coils use only high density edge wound flat OFC wire and operate in a precision long magnetic gap.Front and rear magnetic venting not only reduces airflow and noise, but increases power handling and long term reliability. Meanwhile,massive motor assemblies offer no- compromise optimisation for each voice coil diameter.
The unique ‘Soft Dome’ technology in the form of the latest SM-150 s was developed by ATC in 1976 and features in the SCM50. Its arrival revolutionised professional studio monitoring. Remarkable today, as then, it remains the only mid-range device capable of giving ultimate performance. The ‘Super Linear Technology’ found in all the Tower models is equally ground breaking .It has long been recognised that the detrimental effects of magnetic hysteresis is a significant factor in the production of distortion in drive units. For instance,our hand-wound short voice coils use only high density edge wound flat OFC wire and operate in a precision long magnetic gap. Front and rear magnetic venting not only reduces airflow and noise, but increases power handling and long term reliability. With clever use of revolutionary materials developed for the communications industry,the problem has been solved for all time in the form of ATC’s SL drive units.They are unique not only in their ability to accurately reproduce piano, but also the precise manner in which they articulate male voices. This is hardly surprising given the reduction of third harmonic distortion by 10-15 dB between 100Hz and 3kHz.
