Dali SUB K-14 F Subwoofer

Dali SUB K-14 F is going to pick up where the IKON SUB MK2 left off, but with even more power, deep bass and in a smaller and more modern cabinet. The DALI SUB K-14 F is recommended as compliment to the KUBIK FREE as well as the compact models of the ZENSOR and FAZON series. On top of this it is compatible with all Dali loudspeakers including the new Opticon range as the perfect completion of a DALI stereo or surround set up.

Amplifier

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.

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.

Woofer

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 ensures a greater transient response than you would normally expect from a subwoofer in this category. 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.

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. 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.

Cabinet

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 abides to the tough DALI specifications, and gives the woofer an impressive 44 litres to work within.

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

Elegant Simple Design

The rigid cone structure based on either aluminium or cone fibre eliminates the need for a dust-cap and helps ensure a piston-like behaviour of the woofer. All the amplifiers in the DALI subwoofers have the stamina to keep a high-yield performance and the headroom to draw out that little extra when needed.

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