Heritage & Manufacture:
The Sibelius CG is audibly identical to the SG in every aspect. It is only difference is the colour of its drive cone. The Sibelius CG, like its SG counterpart, is designed to deliver extremely lifelike sound reproduction for all genres of music, but especially classical, jazz, folk, blues and rock. From solo voice to small ensembles, chamber, symphonic orchestras, electronic and full on rock, the Sibelius CG faithfully reproduces the full dynamics of the original recording. Its shallow drive cone delivers a very wide and natural soundstage. Close your eyes and the enclosures disapear.
The Sibelius cabinets are crafted from 3.2 cm thick French oak and take a total of 12 weeks to manufacture from start to finish. Each cabinet has its own visual signature and is matched with its left (or right) handed partner, prior to receiving its final colour finish. The drive cones are run-in for 360 hours prior to placing. Run-in sound material varies from classical to rock music, from jazz to folk and large scale opera to speech. This means our loudspeakers are ready to play when you receive them.
Pairing: Because The Sibelius CG’s deliver so much detail (what comes in you hear) they are best paired with well designed, high quality amplifiers. This means; very low distortion, neutral and extremely dynamic. We have no specific preference whether the amplifier design is single ended ‘Class A’ triode vacuum tube, or high quality solid state. In our listening rooms we use all kinds of amplifiers, even a pair of high output, Class D mono-blocks. If we have a preference, it is often for ‘Class A’ but we have also had very good results with current dumping amplifiers and AB (push/pull) amplifiers. Please contact us directly to discuss your specific situation and requirements.
Specifications:
Impedance: 7.2 Ohm
Power handling: 35 Watts RMS – 70 Watts peak
Efficiency: 87db @ 1W @ 1 meter
Maximum output: 105db @ 1 Meter peak (in practice consider 96-98db as a working maximum)
Frequency range: 38Hz-20Khz. (-6db occurs in most acoustically well-balanced listening rooms at around 36Hz)

Note: The Sibelius CG enclosures are made of solid, natural, oak. They are made using the same assembly principles as wooden, musical instruments (i.e. clamped and glued together by hand). This requires that they are kept in suitable conditions, where temperature levels are relatively stable, and humidity does not fall below 40% or exceed 60%.

Finishes & Colours
Making a pair of Sibelius loudspeakers takes time!
Making a pair of Sibelius enclosures is mostly handwork. The whole process takes approximately 12 weeks from the French oak entering the joinery, to the finished pairs leaving for a customer.
Selecting the French Oak, right through to gluing, clamping, chiseling and preparing for finishing.
Before we can apply a stain and a topcoat, be it a varnish or natural wax-oil, the enclosure must be as good as we can make it. Any oversights here means triple work later on!
Hand sanding, smoothing with a steel blade and routing the edges, are all part of the pre-finishing process.
Every enclosure is unique. They need to be selected for their individual characteristics and their suitability for the colour and type of finish our customer is looking for.
Applying a dark stain is a skilled job. It takes a steady hand, time and patience.
