Charlie 4’s key design features, mechanical characteristics and performance parameters include:
A Big Heart In A Small Body
Charlie 4 features a brand new 4” cone transducer, created by Outline’s engineers just for this product, this 100% Italian-made unit is super-efficient and applies the same top-class audio engineering found in our larger transducers to a unit a fraction of their size.
Single-Driver Advantages
Single-driver designs enjoy a major sonic advantage in that they do not suffer from the phase anomalies caused by a crossover and so produce the most natural and uncoloured sound. Outline’s engineers have extended this advantage by creating a new design of membrane which dramatically improves the off-axis performance, a key feature for ultra-compact, multi-application loudspeaker systems.
Designed For Professional Power Amplifiers
The new 4” transducer is designed to be powered by professional power amplifiers and its output is simply prodigious, producing power and reliability that belies its size. Contained within an enclosure measuring just 12cm x 12cm x 12.6cm and weighing only 1.55 Kg, Outline’s world-class audio engineering has produced a robust and reliable integrated design which punches far above its weight in terms of audio performance and service life.
Design That Is Pure Outline
A striking design feature of Charlie 4 is the pair of O-rings at the front and rear of the unit. Not just aesthetically pleasing, these components also assist with vibration-damping and also stabilise and protect the enclosure from irregular surfaces.
Simple Mounting And Location
Every Charlie 4 includes a multi-adaptable mounting bracket, again designed specifically for this product. A pair of M6 bolts locate through the bracket and into threaded inserts in the loudspeaker, while the adjustment range and shape of the bracket allow it to be mounted securely on virtually any surface.
Processing And Power
Outline’s ground-breaking L3000 power amplifier is the ideal partner for Charlie 4. Its flexibility, power and onboard DSP are all contained within its surprisingly modest size. Alternatively, any of Outline’s amplifiers will work just as well and the iP24 processor is the perfect external processing partner.
