I heard the GURUs for the first time at Rocky Mountain Audio Fest where I got to listen to Ingvar Öhman, their designer. He talked about the design of his speakers and what went into their manufacture. I also got to meet Lars Erickson, the managing director for Sjöfen HiFi at RMAF. Sjöfen is the North American importer of GURU Loudspeakers, SUPRA loud speaker cables, and several other brands, that for some reason, are not spelled in all capital letters. I had met Lars online last summer when I purchased some SUPRA speaker cables. Lars contacted me late in 2008 and asked me if I would like to review the GURU speakers for Positive Feedback Online.
The Swedish-made Guru QM10 loudspeaker is a small, two-way monitor loudspeaker. It measures only 12 inches wide by 10 inches deep, by 9.5 inches tall and weighs just 13 pounds. A single pair of European-style 4mm binding posts is located on the rear of the enclosure.
The drivers consist of a 16mm German-made tweeter and 102mm (four-inch) paper-coned midrange/woofer made by Tymphany of Denmark to GURU's specifications. These work in a vented 10-liter enclosure and are crossed over at 2,700 Hz. GURU claims a low-frequency response down to 30Hz. That's low for any speaker, much less one this small.
The GURU QM10 truly is a monitor loudspeak...
