English loudspeaker company, Graham Audio, continues its homage to the finest BBC designs by updating the stand mount monitor, LS5/5 in 2019, considered the finest monitor ever designed by the BBC. In 2022 a floor-standing version, LS5/5f is debut at the High-End Munich Show in a passive display with the first worldwide active demonstration in North America, promising midrange magic as presenters spin analogue tunes.
An engineer from the BBC described the LS5/5 as the best speaker that the BBC ever designed. It was replaced by the LS5/8 at the advent of the Rock era in the seventies, as the artists wanted speakers that could play louder. Derek Hughes 2019 version of the 5/5 has 9dB greater power handling due to the improvements over the past fifty years in magnets, glues, cabling, capacitors, coils etc.
The LS5/5f has the same driver complement & cabinet as the LS5/5, but as a modified (in the bass region) crossover and an additional 16” enclosure underneath. The second cabinet underneath the drivers & crossover cabinet is an acoustic chamber that allows the bass driver to breathe. This ported enclosure provides increased bass extension and dynamic capability. Though the floor standing version has a similar midrange to its stand-mount sibling, it enjoys 7dB more bass, as measured at 20Hz.
The wood slots covering the bass drivers control the dispersion and make the speakers easier to position in a room. ¾ of the volume in size of the 5/8, it has an 8” woofer for the midrange in its own sealed compartment. A more complex crossover accounts for much of the weight differential, the smaller speaker is some 20 – 30lbs heavier than its larger sibling.
- The LS5/5f is available in Cherry and Oak. Optional Finishes available with tiered pricing (Rosewood and Walnut, and Ebony).
- Choice of fasteners: zinc plated (for light cabinets), painted steel black (for dark cabinets).
- Choice of Grills: black or off-white
