Features & Specs
12″ carbon fiber driver with 4″ voice coil
The SPL-X 12’s larger 12″ carbon cone and 4″ voice coil deliver higher output and deeper extension than the 10″ model while retaining excellent transient response. This makes it well-suited to medium and larger listening rooms where greater bass headroom is needed.
1200 W RMS / 1700 W peak Class D amplifier
With 1200 W RMS power on tap and 1700 W peak, the Class D amplifier maintains control over the large driver even on demanding bass passages. The result is authoritative low-frequency performance with ample dynamic headroom.
DSP with AutoEQ, 6-band parametric EQ and app control
The built-in DSP and AutoEQ microphone measure the room and automatically optimize the frequency response. Users can then fine-tune via a 6-band parametric EQ in the companion app, adjusting crossover, phase and filters from the listening position.
Sealed HDF cabinet for tight, accurate bass
The robust sealed HDF enclosure minimizes port noise and unwanted resonances, supporting accurate low-frequency reproduction that integrates smoothly with main speakers. This design favors speed and clarity over exaggerated bass bloom.
RCA, XLR and high-level inputs and outputs
Comprehensive analog connectivity allows the SPL-X 12 to work with a wide range of AV processors, receivers and stereo amps, including balanced XLR chains. The corresponding outputs simplify multi-sub setups and complex system routing.
Auto power-on with multi-voltage operation
An auto power-on circuit with adjustable sensitivity, plus On/Auto/Trigger modes, ensures the sub is ready when needed while minimizing standby power consumption. Multi-voltage support (115–230 V) allows use in different regions without additional hardware.
