...e profile allowing Laminar airflow. The association of the modern components with the new vents delivers a greatly improved +5 dB peak SPL output compared to the previous standards.

The control and amplification of the SB28 is managed by the LA8 platform. The DSP filtering encompasses advanced crossover functions, system EQ, and L-DRIVE thermal and overexcursion protection of the transducers. The L-ACOUSTICS LA8 amplified controller offers the following drive modes:

* The ''standard'' mode using SB28 as a comPanion to K1, KUDO, V-DOSC and ARCS, featuring a low-pass filter at 60 Hz ([SB28_60] preset) or closely coupled to ARCS with a low-pass filter at 100 Hz ([SB28_100] preset)
* The ''cardioid'' mode using SB28 as a comPanion to K1, KUDO, V-DOSC, and ARCS, featuring a low-pass filter at 60 Hz ([SB28_60_C] preset) or closely coupled to ARCS with a low-pass filter at 100 Hz ([SB28_100_C] preset)

The performance of the SB28 enclosure depends upon the choice of preset and physical system configuration.

Made of high grade Baltic birch plywood, the cabinet also features industry standard Aeroquip rails for line array rigging.

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.
