RIGID CONE STRUCTURE

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

ELEGANT AND SIMPLE DESIGN

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

HIGH-YIELD AMPLIFIER

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

FLEXIBLE CONNECTIVITY

With the choice of LFE, mono and stereo LINE inputs, DALI subwoofers are compatible with almost any amplifier, receiver or processor.

Built around a 14” aluminium long stroke woofer with a 500-watt class D amplifier, the DALI SUB K-14 F has the power and the control for both impressive movie- and delightful music-reproduction. Connect the sub to your amplifier through LFE or line-out, and prepare to be pushed down in your seat.

DALI recommends applying this subwoofer with for example RUBICON, OPTICON or ZENSOR systems. However, customer with speakers from other brands will surely also find what they need in this sub.

Cleverly designed, the SUB K-14 F is a big subwoofer, but with a non intrusive design. The 14” woofer reaches almost to the edge of the elegant looking high gloss front baffle, giving the appearance of a large woofer and small cabinet. Built from solid MDF, the 430 x 395 x 425 mm cabinet satisfies all of DALI's tough requirements, and gives the woofer an impressive 44 litres to work within.

The cabinet enclosure comes in two finishes: Black Ash with a black high gloss front baffle, and White Silk Matte fronted by a white high gloss baffle.

The entire cabinet is effectively decoupled from the floor by means of a sleek aluminium base. Making the box appear to hover above the floor by 50 mm, this distance eliminates any potential turbulence from the space between the cabinet and the floor itself, yet maintains proximity to ensure that the benefit of having a downward-firing port is maintained; a higher efficiency and more freedom in positioning.

Ensuring more than adequate 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 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, DALI worked 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, so with an eye on performance and to keep the signal clear and undistorted, the necessary filter is also applied in analog. This filter is tuned to maximise the use of the woofer and hence 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 the maximum amplifier output power threshold. If the incoming signal, at a certain volume setting, will exceed the threshold, 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.

The SUB K-14 F incorporates a 14” woofer with a deep black coloured aluminium cone. Chosen for its stiff yet lightweight properties, the aluminium cone will exceed your expectations when it comes to transient response. Very much in line with DALI’s philosophy in building speakers, the ability to start and stop very quickly enables easy integration with the front speakers.

Designed to be a closed cone you will find no dust cap. Instead it is an integrated part of the cone itself. This also contributes to ensuring a piston-like behaviour. Consequently, distortion is kept to an absolute minimum – especially in the low frequency area where the subwoofer operates.

The woofer motor is built around an ‘oversized’ ferrite magnet, and optimised for maximum flux in the voice coil gap. This carefully designed magnet system enabled the project team to reach a high B/L product to enable the SUB K-14 F to render the finer low frequency details of music, but also at a higher sound pressure level. The measured BxL value of 17 N/A servfes to indicate the level of control and precision that was reached, rarely to be found. A listening session will convince you that DALI have done the right thing.

The 30 mm long, 4 layer voice coil is built for long excursions. It is vented to ensure air cooling to the system and to the coil itself, keeping the temperature down, which creates a stable bass response.

The pole piece is also vented for maximum cooling, but also to reduce internal compression in the motor system, which ensures free movement of the cone without any over-/underpressure affecting the performance.

Adhering to the low-loss sound design principle, the surround of the woofer is built to allow long and linear excursion. The oversized suspension is designed to allow both weak and strong transients to turn into undistorted acoustic signals.
