When listening out for the striking of piano notes, drum beats or plucked strings the ATC’s quick nature snaps into action with a controlled edge peaks with the first portion of a note and lays out the follow through with fantastic timing. The speakers although not high current demanding require an amplifier with some good power as they are not very sensitive at 84db, so ATC recommend an amplifier of at least 75wpc, the Rowland can output twice that into class A/B.ĭuring playback of some very minimalist Acoustic work it was really very obvious that the SCM11’s have a quick transient response. Interested to hear what the new tweeter was going to offer the overall performance of the SCM11, I hooked them up to my Jeff Rowland integrated. The components used are high power rated wire wound resistors, audio grade metalised polypropylene film capacitors and air cored inductors. With the new tweeters in place this was of course a natural event that the crossovers would be reworked. Inside the packaging is two drawstring cotton bags, personally I’d be inclined to place them over the speakers when not in use for protection.
Atc scm11 version 2 drivers#
I voiced concerns at the time that after a period of time surely they would gather dust but was soon reassured by ATC’s PR guy Keith Haddock that he has multiple pairs in what he calls his ‘shack’ his man cave out in the garden and although he does admit to dragging in dirt and dust frequently he firmly stated that the drivers haven’t collected any particles and look as new still.
Atc scm11 version 2 driver#
The mid bass driver is made from acrylic and soaked in the formula leaving a slightly sticky to the touch feel. Being of a low mass it allows the driver to remain fast and accurate as well as having high damping properties removing excess energy and controlling unwanted resonances. The SH25-76 tweeter is the brainchild of ATC and is constructed in house, comprising of 8 parts including a doped polyester diaphragm and suspension system and a neodymium motor assembly keeping the tweeter small and of low mass for close positioning with the mid bass driver for critical integration of frequencies, although ATC do produce drivers for other companies (I recall the midrange driver on a set of Ruark Crusader III’s which my brother owned) the new tweeter is strictly off limits and only features in ATC’s range of loudspeakers.Īll ATC drivers use their own specially formulated doping compound.
Atc scm11 version 2 upgrade#
The next significant upgrade to the speakers was a new tweeter.
Finish in a real wood cherry veneer or black the SCM11’s looked fantastic on inspection after arrival (review samples were in cherry).
The cabinets are constructed from multiple laminated layers of medium density fibreboard and all planes are of the same thickness and strengthened with horizontal bracing increasing rigidity and damping. The SCM (Studio Control Monitor) range of loudspeakers and undergone a redesign and revamp of late, most noticeable is the new curved cabinets functionally superior and visually more appealing than the classic box type design.
