Pioneer announced two new high-quality loudspeaker sets to complement its EX Speaker Series: the S-4EX bookshelf and S-8EX centre speakers. Constructed with the same award-winning design technology as last year's S-3EX tall boy speakers, these smaller sized multi-channel solutions bring the high definition audio experience to life. Together with the S-3EX tall boy speakers, Pioneer now provides a complete high-end multi-channel system to fulfil the needs of the most demanding audiophiles.

Pioneer's critically acclaimed Technical Audio Devices (TAD), the most advanced materials have been used in order to deliver an unparalleled audio performance. The renowned design technology includes a ceramic graphite diaphragm tweeter mounted concentrically within a magnesium coned midrange driver and the Precision Curve cabinet design that functions to enclose the listener in a 'virtual sphere' of surround sound perfection. Designed to complement the EX series of drivers, the S-4EX bookshelf and S-8EX center channel were each constructed with the same heralded technology as used in last year's S-3EX tall boy speakers. When coupled with said boys, you've got yourself a complete multi-channel system consisting of EX drivers from top to bottom.

Taking advantage of Pioneer's audio engineering expertise, listeners will gain audio performance full of sharpness, clarity and high frequency response that will immerse them in sound like never before.

Ceramic graphite's lightness and exceptional strength push the diaphragm resonance far beyond the audible range, which results in a cleaner and more accurate sound reproduction. Thanks to this improvement, the new Pioneer speakers can reproduce the very high frequencies of DVD Audio and SACD formats.

The outstanding sound produced by the EX Series Speakers is a direct result of the solid construction and the finest materials used in their creation.

The bass driver serves as the foundation of the S-4EX and S-8EX speaker systems. With its extremely rigid cone structure, highly linear magnetic circuit and solid aluminium basket frame, this woofer performs strong, deep and fast bass, as well as fluent transitions to the midrange driver. The magnetic circuit is the engine of a driver. To get outstanding bass, it must not only be powerful, it must be able to keep this power constant as well. Pioneer's unique Linear Drive Magnetic Circuit is optimised to increase the unit's power handling capability and keep the very high dynamic of a real instrument's low frequencies.

Both loudspeakers support an impressive 160 watts of total power.

Pioneer has developed the unique ABD (Acoustic Balance Drive) simulation technology. ABD allows for the port and bass drivers to be placed in the best position to cut the influence of the first vertical standing wave. The second vertical standing wave is cancelled by an internal resonator using our proprietary AFAST (Acoustical Filter Assisted System Tuning) technology. The result is precise and dynamic bass with no low midrange colouration.

The S-4EX and S-8EX speakers come in elegant beech high-gloss veneer or a dark teak matte finish.
