Heritage & Manufacture:

The Sibelius SG is a single drive unit, floor standing loudspeaker utilizing an internal front loaded, quarter wave ‘V’ horn. It has a shallow, all alloy drive cone which is mounted into a solid oak cabinet. Apart from the internal connecting leads, terminal posts and internal dampening materials, The Sibelius SG has no other components.

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 Sibelius SG is comfortable covering most genres of music but especially acoustic instruments either in classical, jazz, folk, blues and light rock. From solo voice to small ensembles, chamber and symphonic orchestras the Sibelius SG faithfully reproduces the full dynamics required by each type.

Pairing: Because The Sibelius SG delivers so much detail (nothing is lost) it is best paired with very high quality amplifiers. This means; ‘low distortion’ and extremely dynamic. We have no specific preference whether it is single ended ‘Class A’ triode vacuum tube amplifiers or high quality solid state amplifiers. In our listening rooms we use all kinds of amplifiers, including very high-end Class D. If we have a preference it is for ‘Class A’ or the absolute best class ‘D’. However we have also had very good results with current dumping amplifiers, which can handle massive transients without the distortion sometimes found in lower quality AB (push-pull) amplifiers.
