Making sure there is enough power to move the large woofer, the 450 watts RMS integrated amplifier has the stamina to keep pushing and the headroom to draw out that little extra when needed. Constructed for lasting effect, it is powered by a switch mode power supply (SWPS) that helps keep the module at a low working temperature. For that reason there is no external heat sink on the SUB K-14 F.

Knowing that the SUB K-14 F will find itself working for hours on end, we wanted to secure the amplifier against overheating. The built in PTC ensures that even if the SUB K-14 F should become overheated, it will automatically shut down until the temperature is back at operating level and then turn back on.

The Class-D amplifier takes an analogue signal, and with an eye on performance and to keep the signal clear and undistorted, an analogue filter is applied. This filter is tuned to maximize the use of the woofer and thereby the output from the SUB K-14 F. To improve sound reproduction and to avoid excessive distortion at extreme output sound pressure levels, a power limiter has been incorporated in the amplifier signal path.

The integrated limiter works by constantly comparing the incoming audio signal to a threshold defining the maximum amplifier output power. If the incoming signal, at a certain volume setting, is about to exceed the maximum amplifier output power the level is automatically limited without introducing audible level differences or pumping artefacts. This is done to avoid clipping of the audio signal that will cause distortion and to prevent the amplifier from being damaged. The limiter is only functional at extreme sound pressure levels.

Fitted with controls for gain, cut-off frequency, and phase, the DALI SUB K-14 F will adapt to most front speaker and room acoustics. And, with a choice of LFE and LINE level inputs, it can be connected to almost any amplifier, receiver or processor.

RIGID CONE STRUCTURE

The rigid cone structure based on either aluminium or cone fiber eliminates the need for a dust-cap and helps ensure a piston-like behaviour of the woofer.

 HIGH YIELD AMPLIFIER

All amplifiers in DALI subwoofers have the stamina to keep a high-yield performance and the headroom to draw out that little extra when needed.

FLEXIBLE CONNECTIVITY

All DALI subwoofers are compatible with almost any amplifier, receiver or processor due to the choice of LFE or LINE inputs.

ELEGANT AND SIMPLE DESIGN

The cabinet is designed to fit perfectly to the size of the woofer, but without forgoing the inner volume that is needed to produce a powerful bass performance.
