KEF Audio Ci4100QLb Subwoofer

KEF Audio

Founded in 1961 and now going strongly in its 5th decade, KEF is still developing world-beating products. Scientific innovation and hands-on experimentation continue to underwrite its reputation as one of the audiophile’s ultimate loudspeaker manufacturers. WE REGRET THAT KEF AUDIO PRODUCTS ARE FOR SALE IN THE UK AND IRELAND ONLY.


For the ultimate in Extreme Home Theatre, the formidable new Ci Reference Series Ci4100RLb in-wall subwoofer has the deep bass and theatre thumping output capabilities of a traditional KEF subwoofer coupled with the ability to deliver all the drama and emotional intensity of full theatre sound quality. With four high-output 100mm sub-bass drivers the Ci4100RLb is designed to be matched with KEF’s powerful KASA500 system amplifier. Each KASA500 can power up to two of the Ci4100RLb subwoofers for even the most demanding theatre installations.
