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.
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.
The SUB K-14 F incorporates a 14” woofer with a deep black coloured aluminium cone. The motor of the woofer is built around an ‘oversized’ ferrite magnet, and optimized for maximum flux within 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 is a good indication of the level of control and precision that was reached, and rarely to be found in this category at all.
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. Also, the pole piece is vented for maximum cooling. The venting here has another purpose though; it reduces internal compression in the motor system, which ensures free movement of the cone without any over-/underpressure affecting the performance.
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 cabinet enclosure comes in two finishes: the Black Ash finish is matched with a black high gloss front baffle, and the White Silk Matte finish is fronted by a white high gloss baffle.
