Atlantic Technology 642e THX Select 350 Watt Subwoofer

THX Select 350 watt powered sub-woofer
Description

Sitting at the top of the range, the 642e SB  is arguably Atlantic's 'reference' sub-woofer. Benefiting from years of development, the 642e SB is a product produced from a hybrid of performance engineering, attention to detail and design prowess.

The Atlantic Technology 642e SB THX Select powered sub-woofer is a significant upgrade from its highly acclaimed predecessor. Compared to the original 642, Atlantic Technology have developed a totally new driver with three times the motor size, a stiffer spider, and a heavier cone. It's a real "monster" of a driver as well, as While the driver's free-air resonance remains at 25 Hz, the output of the sub from 35 Hz to 60 Hz-right in the impact range- has been improved by almost 3dB. Atlantic have also modified the equalization (because of the new driver's improved low-frequency output, less amp power is needed for EQ, and consequently more power is available for SPL), limiting and soft clipping parameters of the amplifier to optimize its performance.

Powered by a high-efficiency 350 watt amplifier, the 642e SB utilizes the latest in amplifier technology, with an output stage capable of extremely high current delivery and maximum efficiency for exceptional driver control and cool thermal operation. As a custom-designed amplifier, it has been precision matched and equalized to the new 12" driver. With a useful in-room frequency response of 20Hz to 150Hz, the 642e SB sub-woofer is designed to deliver its rated performance under actual listening conditions, when properly placed and adjusted. Additionally, an adjustable (40Hz to 140Hz) 18dB per octave Low Pass crossover with steep upper end roll-off allows for much better bass integration with your main speakers.

The result of these changes is a perceived 50-watt increase. In other words, the amplifier plays louder than before, with less distortion at its limits. The 642e SB features a sealed enclosure design for low distortion and smoother bass output. Sealed enclosure woofer designs are inherently low in distortion, and deliver deep smooth bass response with a gradual and predictable roll-off below resonance.

As with all Atlantic Technology sub-woofers, close attention has been paid to providing accurate musical bass reproduction along with terrific special effects. Atlantic's proprietary Clear Filter Technology™ ensures that the bass is detailed and accurate.

For those of you wanting to set a reference point in THX performance levels, the Atlantic Technology 642e is a THX Select product, and obviously then matches their reference range of free standing speakers - the 6200e and 8200e flagship systems. So it is at home with the best performance Atlantic offers, which equally sets it free to be matched with other leading THX systems and installations across the board. It is the best expression of Atlantic Technology's honed craft, as it's performance delivers incredibly solid and punchy, bass - but with that superb definition and quickness that only Atlantic Technology can master.
