Direct Servo technology
All our subwoofers feature our Direct Servo technology, which is our secret to achieving tight and accurate bass. The benefits are far more than simply achieving low distortion.
12″ light weight paper high excursion driver
Driver features include:
- Light weight paper cone
- Low moving mass to ensure an exceptional transient response
- High flux density in the gap to ensure low distortion
- Flux modulation shorting rings to lower inductance and improve linearity
- Extended upper bandwidth response allowing a higher crossover point than most
Quality enclosure
Our enclosures are very solid and well braced to minimize any cabinet resonances or coloration. Customer can choose either black oak or black matte finish.
Bass extension controls
The bass extension control enables the user to customize the frequency response of the low end for the best trade-off between output and extension. If set to low music, bass has the lowest phase shift among ported subs. However, the disadvantage is slower attenuation of subsonic signals. For HT application, we recommend low-HT mode which incorporates an additional 2rd order highpass filter to filter out subsonic signals below 20hz. High extension setting is recommended for application where longer playback time and lower power consumption is required.
Crossover options
To suit different setups, we provide a 12 db and 24 db/octave crossover. If you are still using stereo receiver or conventional pre/power amp setup, then we recommend the 24 db switch setting. To understand more about how to correctly integrate your subwoofer, read our phase alignment article.
Integration
This subwoofer is designed to use with the bass management in an AV receiver. With many subwoofers, it is difficult to get a correct and seamless integration with the main speakers because the amplifier settings are often very different to the measured response. You may set the crossover point to 80 Hz, but the actual crossover point may be anywhere between 60 and 100 Hz! The crossover control knob on our plate amplifier can serve as a fine tuning tool to reduce the overlap in output between the main speakers and the subwoofer. The sub has 3 extension settings for 3 different frequency response contours. Low extension setting also employs low damping to give a more full-body bass sound. High extension setting, on the other hand, employs high damping to give a more articulate bass sound.
Output, extension and user preferences
Vented subwoofers do have more phase delay at the low end frequency spectrum. That combined with poor room acoustics sometimes produces boomy bass sound. We have variable extension frequency and damping settings to address that. Customers should experiment with extension filter settings. Low extension setting is recommended for HT use whereas high extension setting (24hz, Q=0.8) is recommend for music.
