The subwoofer class has grown exponentially over the previous decade with a particularly wide selection of choices from nearly each high-end loudspeaker producer.
One can spend anyplace from $400 to $50,000 on a single subwoofer and whist that may appear excessive for a part that has a somewhat restricted operate — it’s one that may positively or negatively impression the general sound of your system if you choose the incorrect one or don’t take the time to experiment with placement.
There’s additionally some advantage to the idea of choosing one from the identical model as your major loudspeakers as a result of the voicing is prone to be very related.
That’s very true for one thing like the brand new ATC C4 Sub MK 2.
Acoustic Transducer Firm (ATC) has simply launched the C4 Sub Mk 2 energetic subwoofer system with a beginning worth of $5,999 USD relying on the end. Though the value is somewhat steep, it’s half the price of the mannequin it replaces!
The brand new C4 Sub Mk2 follows the unique C4 Sub’s design ethos to naturally improve low-frequency response throughout ATC’s line of energetic/passive audio system (SCM19, SCM20, SCM40, SCM50 and SCM100) with out masking particulars or altering the tonal character within the higher bass/decrease mid-range.
It additionally supplies an improve path to clients proudly owning smaller loudspeakers and missing house for bigger stereo loudspeakers while additionally strengthening ATC’s choices for dwelling theater programs.
Designed to mix the best requirements of driver and electronics engineering in a single system, the C4 Sub Mk 2 deploys the all-new proprietary 12-inch SS75-314SC sub-bass driver with a newly developed 300W class AB amplifier.
Each components hand-built and put in inside a considerable cupboard on the firm’s Stroud-based manufacturing HQ.
Tip: ATC’s subwoofer line at present consists of the smaller C1 Sub Mk2 ($2,999) and bigger C6 Sub ($14,999).
New ATC Sub-Bass Driver
The C4 Sub Mk 2 options the brand new SS75-314SC sub-bass driver, the primary to be purpose-built for an ATC sub-bass system and developed by the R&D workforce to breed the bottom 4 octaves of the audio band.
With a view to obtain this the design exploits ATC’s signature long-gap/short-coil configuration to its pure limits with an exceptionally lengthy 30mm magnetic hole, surrounded by a 6-inch/150mm N48M Neodymium magnet – probably the most highly effective ever assembled by ATC and a primary for the corporate.
In assist, the wholly redesigned motor system encompasses a new rubber roll-surround for prime tour functionality, a brand new spider for optimized compliance geometry, and excessive movement motor venting for low noise and compression.
In addition to minimizing distortion, this unprecedented short-coil long-gap configuration ensures the voice coil stays inside the motor construction – even at excessive drive ranges – maximizing cooling, decreasing energy compression, and bettering reliability. Turbulent air noise inside the driver is minimized by a big, flared vent working via the middle of the motor construction, which has the additional benefit of accelerating voice coil and motor cooling.
Consequently, the C4 Sub Mk2 delivers an prolonged low-frequency response whereas avoiding digital equalization, not like many subwoofers accessible as we speak. As a substitute, the extra elegant mixture of remarkable transducer engineering and a touch bigger cupboard quantity is used. The simplicity of this strategy reduces part shift and group delay, aiding the combination of the sub with the partnering loudspeakers.
As well as, a number of subs could be employed to additional elevate efficiency in bigger rooms or when partnering bigger loudspeakers. Buffered linkable inputs and outputs make connection of a number of subs simple.
New 300W ATC Amplifier
The all-new 300W class AB design is exactly optimized to the necessities of the brand new driver, leading to quick, dynamic bass with minimal coloration. Two balanced line inputs present connectivity for stereo or AV/dwelling cinema programs whereas two balanced outputs can be found to feed partnering ‘important’ stereo loudspeakers or to ‘daisy-chain’ a number of subs.
Low-pass filters are analogue, 4th order Linkwitz-Riley, with filter frequency choices making certain optimum integration with partnering audio system. As well as, an industry-standard 80Hz low-pass filter and an ‘off’ possibility (to be used with exterior processing) is joined by a polarity change, variable 180° part adjustment and a stepped attenuator over a 21 dB vary for exact stage matching.
Tip: The earlier era ATC C4 Sub used 450-watt Class G amplifier.
Cupboard
Hand-built and completed at ATC’s cupboard manufacturing facility and sharing styling with the model’s ‘Traditional’ and ‘Tower’ sequence loudspeakers, the C4 Sub Mk 2’s 70-liter cupboard employs 25mm/1-inch-thick panels and heavy bracing.
It’s accessible in customary Cherry, Black Ash, Walnut and Oak real-wood veneers, in addition to Satin Black and Satin White finishes, or in premium Rosewood, European Crown Minimize Walnut, Burr Magnolia, and Pippy Oak real-wood veneers, with the choice of excessive gloss over veneers and black/white piano lacquers additionally accessible.
