Atlantic Technology SBT500/1000 Dual-Woofer Subwoofer

SBT500/1000

Ultra-High Power, 1,000-Watt, Dual 12-Inch and 500-Watt Dual 10-Inch Subwoofers

The SBT Series extend Atlantic’s legacy for designing subwoofers, delivering power and impact without sacrificing detail and taking articulation to a new level. With dual woofers, higher-power and new digital circuit designs, the SBT series are engineered with the latest technology and finest components available to bring sonic performance to new levels of depth, power and clarity.

Our subs never fall into the “one-note bass boom” trap common in conventional subs. Instead of conventional “compressor-limiter” distortion-reduction, Atlantic employs its special Clear Filter Technology (or CFT) circuitry. This greatly enhances articulation and detail of instrumentation, vocals and special effects in upper bass and lower mid-range frequencies by reducing resonance colorations inherent to subwoofer enclosures in these octaves.

That’s why other subwoofers, regardless of their power ratings, can’t match the sound of an Atlantic subwoofer for detail and musical accuracy.

And with the SBT Series Subwoofers, Atlantic has improved CFT by designing a sophisticated new DSP circuit for the crossover, signal contouring and limiting to prevent over-excursion of the drivers and deliver a clear articulate performance.

Dual long-throw composite cone bass drivers, each with a vented motor structure and high temperature, 2-inch, 4-layer voice coil. This powerful driver design has a very stiff cone that acts like a piston through its operating range. Its massive magnetic motor assembly and high temperature component parts deliver exceptional performance and reliability.
Sealed, acoustic-suspension bass-alignment with a robust braced MDF enclosure. This delivers low distortion, superior transient response and extended deep bass output, resulting in Atlantic’s renowned accurate musical bass reproduction with wide dynamic range for stunning special effects.
High-efficiency 500 and 1000 watt amplifiers. The digital output stages are capable of very high current delivery for exceptional driver control and headroom while ensuring cool, reliable operation. Each amplifier is precision matched and equalized to its specific driver resulting in powerful, controlled bass with great articulation and authority.
Volume control. Sets the subwoofer’s overall output to match the sound level with the rest of the audio system.
Continuous Adjustable 40 Hz to 140 Hz, 24dB per octave low pass crossover. The steep 24dB per octave slope allows for much better blending with the satellite speakers while making the woofer less localizable.
Low Pass/Bypass Switch. The Low Pass setting sets the upper frequency limit of the subwoofer with the sub’s adjustable crossover control. A Bypass setting is for processors and receivers with their own crossovers and low-pass outputs.
EQ Switch. The Max SPL position provides stronger overall output with restricted deep bass output. The Max Range position provides deeper bass extension with restricted maximum overall output.
Absolute Phase Invert Switch. This switches between normal or inverted phase to allow better acoustic matching and blending with satellite speaker systems. This switch also allows you to compensate for unusual room acoustics that occur when the woofer is physically separated from the main speakers by a significant distance.
Choice of Line In and XLR inputs. Connect mono or stereo signals to line or XLR inputs for better rejection of hum and noise over longer cable runs for more flexible sub placement in larger rooms.
Main Power/Automatic standby. The three position power switch (on/off/standby) gives users operational flexibility. Automatic standby senses a signal presence to turn the subwoofer on. It automatically turns back to standby with a 7 to 10 minute delay when no signal is present.
LED Status Indicators: The multi-color power indicator LED located on the amplifier panel glows green when on, yellow in standby and red when off.
110-120/220-240V (50/60Hz) Input Voltage Switch. Allows for international use with industry standard user detachable cables connecting to the sub’s IEC-320-13 power input socket.

Atlantic Powered Subwoofers

All Atlantic powered subwoofers share their essential design approach and philosophy: Heavy-duty woofers in optimally sized enclosures, powered by high-current amplifiers. They all use the sealed “acoustic suspension” bass alignment method which delivers superior transient response for greater clarity and detail, and a more gradual low-frequency rolloff that requires less power-robbing equalization from the on-board amplifier.

We’ve also developed an exclusive feature called Clear Filter Technology (CFT™) that actually reduces the deleterious effects the enclosure itself can have on the sound. All enclosures have dimensionally-dependent resonances. Those resonances can impart a negative ‘coloration” to the sound. In subwoofers, this negative effect usually occurs in the upper bass range and can make upper bass/lower midrange sounds like male voices or the upper ranges of bass guitar sound unnaturally heavy or ‘thumpy.’ This is true even if your subwoofer is “crossed over” in what you think is the low bass region–lower than 80 Hz or so–because crossovers are not absolute. So even if your subwoofer is crossed over at 80 Hz, it is still producing significant output up to about 180-200 Hz. Atlantic’s Clear Filter introduces a reciprocal correction in the exact frequency region where these problems occur, resulting in a markedly cleaner, more detailed sound. Every one of our subwoofers has its own Clear Filter, optimized specifically for that particular model.

Our subs utilize an adjustable (40Hz to 140Hz) 18dB per octave Low Pass crossover that allows much better bass integration with the satellite speakers while making the woofer less localizable. Meanwhile, the Phase Invert switch (Normal/Invert) allows precise acoustic matching with satellite speaker systems whose output relative to the subwoofer may be phase reversed. This switch also allows you to compensate for unusual room acoustics that occur when the woofer is physically separated from the main speakers by a significant distance.

Other features are convenient front panel mounted Level Control and automatic standby operation with a multi-color LED status indicator. The automatic standby feature offers signal sensing turn-on with a 7-10 minute turn-off delay. There’s a multi-color LED status indicator that lets you know when the unit is on or in standby. Automatic Standby can be defeated by placing the rear mounted switch in the ON position. Finally, they are all designed and built to meet all current domestic and European safety requirements, making it one of the most sophisticated subwoofers to be produced anywhere.
