Musical Fidelity LS 3/5A

A BBC Icon

A classic monitor marks Musical Fidelity’s re-entry into the loudspeaker market.

Musical Fidelity LS 3/5A

The initial role of the LS 3/5A was that of a versatile monitor for listening in broadcasting vans in Britain. Slowly but steadily, audiophiles realized this speaker’s qualities, especially in smaller rooms.

Over the years, the LS 3/5A has been manufactured by renowned speaker brands according to the BBC R&D design, keeping an eye on the close tolerances that make the LS 3/5A what it is. The sealed box design allows tight, quick bass response and natural midrange reproduction – significant for vocals and instruments.

The appearance is utilitarian, but the speaker still dons a beautiful real wood veneer finish. The voicing of the speakers was done with the grilles in place for optimum sound quality. The unique cabinet features 12mm side walls damped for the LS 3/5A signature sound.

Unlike modern speakers that widely employ 19mm MDF, the LS 3/5A uses 12mm multiplex wood that is further damped on the inside: A design that has proven itself for over 45 years. The beautiful palisander wood veneer complements any living space.

Beautiful Soundstage, Quick Bass

The Musical Fidelity LS 3/5A offers a beautiful soundstage that goes way beyond the physical boundaries of the cabinets. The sealed cabinet, in combination with the damped, relatively thin sidewalls, is responsible for the dry, quick bass that goes deeper than you’d expect from a speaker this size.

A true 3/5A

Extensive testing and long listening sessions went into the crossover network to make the custom drivers work together seamlessly. The precisely matched drivers and cabinets used in the Musical Fidelity LS 3/5A comply with the BBC R&D design 1976/29.
