Polk Audio S30CE Signature Polk Audio Signature S30 E Centre Speaker - Black £130.01 @ Amazon

The Polk S30e uses Dynamic Balance Technology to ensure a performance that always has a clean, full range sound. The technology is capable of analysing the speaker’s electro-acoustic and mechanical system for improved material selection and efficient geometry, to pinpoint and eliminate issues that potentially reduce the speaker’s performance. The tweeter of the S30e is a terylene dome tweeter, featuring curvilinear formers to extend response and lower resonance. The ceramic motor extends low frequency response for increased dispersion in the midrange, with the tweeter delivering detailed high frequency capable of producing 40 kHz for high resolution audio.

With mica-reinforced polypropylene custom mid-range drivers, the S30e centre is able to produce clean and clear bass with butyl rubber surrounds and four layer voice coils. Massive ceramic motor structures and high-temperature Conex fibre spiders combine to create high efficiency drivers with lower distortion and greater durability.

Constructed from non-resonant MDF, with 19mm thick baffles, the Polk S30e is rigid with acoustically inert enclosures that reduce unwanted resonance for less colouration to the sound, ensuring a more lifelike reproduction and a timbre-matched sound across the Polk Signature E range. The S30e also features gold plated 5-way binding posts, for a direct and efficient connection that is easy to set up.
