The Diana III-F is a modular bass extender from Gold Note, the Florence company, and belongs to its Diana loudspeaker family. Placed under a Diana I or Diana II stand-mount, it turns the pair into a floorstanding loudspeaker with extended bass. Gold Note calls it the first modular extender of its kind.
Key specs that matter
The extender uses a downward-firing 6.5 in fibreglass woofer with a neodymium magnet, working with a front-mounted bass reflex port. Response reaches down to 38 Hz, sensitivity is 91 dB and nominal impedance is 8 ohms. Each extender measures 24.0 x 53.4 x 40.0 cm and weighs 22 kg. The finish is a scratch-resistant black lacquer, and the unit rests on a dedicated stand with four adjustable spikes.
Engineering and use context
Small neodymium magnets concealed in the top panel locate the Diana I or II in exactly the right spot. A custom bridge passes the audio signal from one cabinet to the other and also ties the two together, so the stack is as rigid as a single floorstanding enclosure. The cabinet is shaped and treated to cut down vibration. An integrated low-pass filter set at around 80 Hz splits the band between the stand-mount and the extender, and automatic recognition adapts the extender to whichever model sits on top. That lets an owner start with a Diana I and move to a Diana II later on the same extenders, or buy the stand-mounts first and add the extenders afterwards.
Within the family, the Diana I is a two-way with a 6.5 in driver, a rear port and 88 dB sensitivity, while the Diana II is the more sensitive model with two 6.5 in drivers. The whole range is built for high sensitivity, and Gold Note says amplifiers of as little as 10 W can drive it. Shared features include a fabric finish made from recycled racing-car seat material, laminated to internal foam damping, and a mechanical dome phaser in front of the tweeter for wide dispersion. The family also contains the Diana Center, the first home cinema product from Gold Note.
Pairing
The Diana III-F is designed exclusively for the Diana I and Diana II. Topped with the more sensitive Diana II, the combination can be driven by low-powered amplifiers, Gold Note's own integrated models among them.
