Sonner Audio is a small high-end loudspeaker maker led by designer Gunawan Surya, known as Gunny. It builds two-way and 2.5-way ported speakers with ring radiator tweeters and curved cabinets, and sells them in North America and through overseas distributors. The design brief favours an easy, flat impedance load so that low-powered valve amplifiers can drive the speakers.

Range & what it's known for

There are two series. The Allegro range is topped by the Allegro Unum MKII monitor, whose predecessor used a 1-inch ring dome tweeter and a 6-inch magnesium-aluminium mid-woofer in a one-piece curved cabinet with an aluminium baffle, crossed over at 2kHz and wired point to point. The Legato series covers the Legato Unum two-way monitor with a 5.5-inch coated paper cone, the Legato Semis, and the Legato Duo floorstander, a 2.5-way design with crossovers at 200Hz and 2.5kHz.

Who owns it and where it's made

Gunny owns and steers the firm, working with an in-house electrical engineer. The curved Legato Duo cabinet is made in the USA.

The lineup in this catalog

The Allegro Unum MKII and Legato Unum stand-mounts, and the Legato Semis and Legato Duo floorstanders, with response reaching 23kHz and the Legato Duo extending down to 37Hz.

Who it's for

Sonner fits owners of modest-power valve amplifiers who want compact or mid-size speakers. The Legato Unum opens the range, the Legato Semis and Duo add floorstanding scale, and the Allegro Unum MKII is the upgrade for stand-mount buyers.
