Amplifier with Enough Power to Handle Instantaneous
High Volume
Class D amplifier with characteristics of high efficiency, wide
frequency range, and high-precision feedback design is used for
the amplifier unit. This allows plenty of power to reproduce scenes
requiring instantaneous high volume bass. Additionally, the high S/N
ratio design (over 111 dB) constantly provides clear sound, so bass
reproduction is enhanced without compromising the sound quality of
the overall content.
High Linearity Large Woofer for Low-Distortion Clear
Sound Even During High Amplitudes
The subwoofer comes with a large 20 cm woofer unit. The high
linearity characteristic provides quality heavy bass with low distortion,
even during high amplitudes for loud delivery.
Faithful Bass Reproduction with Phase Control
The subwoofer is developed based on Pioneer’s original
Phase Control technology. In addition to a highly linear
woofer unit, the subwoofer also has a low pass filter (LPF)
with a bypassing function. This prevents the bass from
lagging behind other speaker output, and offers richly nuanced heavy
bass with superior transient response.
