Polk S15E Bookshelf Speakers (Pair)

Our Price £199.00 RRP £279.00 Save: £80.00

The Polk S15e Bookshelf speakers improve upon Polk's previous Signature series with Dynamic Balance Technology, high resolution tweeters and acoustically inert enclosures, offering an elevated sound for music and movies, with a sound-matched range for seamless speaker to speaker blending in the Polk Signature E Series.

The Polk S15e 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 S15e 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 a mica-reinforced polypropylene custom mid-range driver, the S15e bookshelf speakers are 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 a high efficiency driver with lower distortion and greater durability.

The S15e speakers feature Polk Power Port technology, a patented design that allows for the smooth transition of air from the port into the listening space. Extending the overall bass port and providing a greater surface area to eliminate turbulence, the Power Port offers a bigger bass for a deep, impactful sound.

Constructed from non-resonant MDF, with 19mm thick baffles, the Polk S15e 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 S15e also features gold plated 5-way binding posts, for a direct and efficient connection that is easy to set up.
