Crossover BBC-Rogers-KEF LS3-5A (LS3/5A) PurplePCB

The LS3/5A is a small studio monitor loudspeaker originated by the BBC for use by outside broadcast vans to ensure quality of their broadcasts. The speaker concept set out transparent and natural sound as the goal, and the achievement of the result is widely acknowledged.

The BBC granted licenses to a small number of British firms, who first manufactured the product in 1975. The product underwent a change in 1987 due to consistency issues in manufacturing, and again in around 2003 when original parts from KEF ran out. Upwards of 60,000 pairs of the speaker have been sold. Reviewers have recognized its enormous importance as a bookshelf design.

Over the years, the LS3/5A became an industry standard for music studios, especially for classical recordings. It also quickly gained interest in the audiophile sector. Due to the small size, the LS3/5A is the perfect fit for small living rooms. Do not get fooled by the size: The speaker surprises with a lot of low end information. Due to the closed type design, the bass is quick and perfectly defined, compared to a bass reflex speaker.
