The iFi RETRO LS3.5 speaker was inspired by the legendry BBC LS3/5a speaker. In order to create
the most open, natural and organic sound, iFi uses the latest technologies combined with natural
materials, to create the LS3.5.
The wideband driver is custom-made to iFi's high specifications. It is made of the super-light
coated natural paper for ultra-fast response and excellent efficiency.
The super tweeter employed is no ordinary tweeter neither, again it is custom-designed and is
performing the job of a super-tweeter. It is made of transparent organic silk, and horn-loaded,
to create a coherent image with the wideband driver.
The cabinet utilised is an advanced multi-chamber P.G.A.H Voigt tuned enclosure with a low
turbulence port to reduce port noise at high levels. This design enhanced the bass performance of
the small speaker to a level seldom achieved before.
The cabinet is made from natural, sustainable bamboo. It is 3 times as strong and has the
weight of a normal wood cabinet. The extra strength and light weight reduce cabinet coloration
