...ture a progressive profile allowing Laminar airflow and reduced turbulence noise even at the very highest operating levels. These combined properties contribute to the sonic qualities of the SB18 in terms of precision and musicality.
The control and amplification of the SB18 is managed by either the LA4 or LA8 (LA-RAK) platform. The onboard DSP filtering encompasses advanced crossover functions, system EQ, and dual thermal and over-excursion protection of the transducer.

The ''standard'' mode using SB18 as a companion to KUDO, KARA, KIVA-KILO, ARCS and featuring a low-pass filter at 60 Hz ([SB18_60] preset) or closely coupled to KARA, ARCS and XT with a low-pass filter at 100 Hz ([SB18_100] preset)
The ''cardioid'' mode using SB18 as a companion to KUDO, KARA, KIVA-KILO, ARCS and featuring a low-pass filter at 60 Hz ([SB18_60_C] preset) or closely coupled to KARA, ARCS and XT with a low-pass filter at 100 Hz ([SB18_100_C] preset).
The performance of the SB18 enclosure depends upon the choice of preset and physical system configuration. Made of high grade Baltic birch plywood, the cabinet also features a pole mount socket for use with one XT or two KIVA enclosures.

Subwoofer

Subwoofers are speakers that are designed to reproduce low-pitched or the bass frequencies typically ranging from about 20 to 200 Hz for consumer products, below 100 Hz for professional live sound, and below 80 Hz in THX-approved systems. These are complete loudspeakers intended to enhance the low frequency range of loudspeakers covering higher frequency bands. Subs, another term for subwoofers, are made up of one or more woofers in a loudspeaker enclosure capable of withstanding air pressure while resisting deformation. These subs require more power to operate because they are bigger (usually between 20.3 cm and 38.1 cm in diameter). Enclosures are available in a variety of designs that differ by efficiency, bandwidth, size and cost. Designs include bass reflex with a port or passive radiator in the enclosure, infinite baffle, horn-loaded, and band pass designs. A multimedia home theater system in low-cost compact plastic cabinet that is said to be a subwoofer is more appropriately called a bass driver because it is too small to produce deep bass. Subwoofers are also powered by amplifiers. Active or powered subwoofers are driven by a built-in amplifier. Passive subwoofers have an external amplifier, subwoofer drivers and enclosures. Subwoofers are popular because of they can pack a large, low frequency punch in a small space, providing a powerful audio experience like being in a movie theater or a concert venue. They are installed in cars or at home as part of a home theater system which is a more common application. In both cases, the subwoofer or low frequency speaker is not considered a stand alone device but helps to reinforce the higher pitched sound produced from the speakers.
