Product features:
Open-hole, closed dual-use subwoofer, new speaker, new digital power amplifier
The new S12-A subwoofer is A 12-inch non-press Cone pine woofer with A specially painted surface
and A unique drying method to create A strong sound basin. Assisted with A long stroke voice coil,
the space grade magnetic circuit can reproduce loose low frequencies with excellent accuracy.
The power supply part of the power amplifier adopts the industry-leading LLC resonant soft switching
power supply technology, which has the advantages of high conversion efficiency, low temperature rise,
low ripple noise, small interference, small volume, large power density, fast dynamic response,
stable output voltage, etc. The power amplifier adopts class-D digital audio technology, with strong
overload capacity, sufficient power reserve, better "dynamic" characteristics, good transient
response, "burst feeling" is very strong.
With the special foam provided by POLINA, the bass reverberation can be plugged, making the S12-A A
closed subwoofer. The frequency response of the two operating modes is slightly different. The guided
subwoofer has a better sense of energy and low frequency extension, while the closed subwoofer has a
clearer sound, better layeriness and faster response time.
