Полочная акустика — AudioSolutions Overture O302B

The Overture O302B ranks below the O322B as the compact bookshelf design within the third-generation Overture MK3 series from AudioSolutions, the Lithuanian speaker company set up in Vilnius in 2011 by Gediminas Gaidelis. For the MK3 update the maker reworked the cabinet, the drivers and the crossover and gave the range a new appearance. Besides this model and its bigger sibling, the Overture family includes the O301C and O311C along with the O303F, O304F, O305F and O306F.

Key specs that matter

The O302B is a two-way design combining a 2.5 cm silk dome tweeter with a 15.2 cm mid-bass unit whose cone is made of ER paper, and the filter hands over between them at 3,000 Hz. AudioSolutions lists an in-room frequency response of 47 Hz to 26,000 Hz and sensitivity of 90 dB measured with 2.83 V at 1 m. Nominal impedance is 4.0 ohm. Power handling is given as 70 W RMS nominal and 140 W maximum unclipped. The cabinet stands 360 mm tall, 210 mm wide and 330 mm deep, and each unit weighs 9 kg, or 12 kg in its carton.

Engineering and use context

Much of the technology comes down from the higher ranges. The enclosure is a heavily braced Sectional-Box-in-a-Box construction modelled on the Virtuoso series, in which a light inner box and a heavy outer box intersect with a polyurethane damping layer between them, so that energy passing from the drivers to the panels is controlled rather than left to oscillate. The mid-bass driver borrows its Extra Rigid cone concept from the Figaro series, while the tweeter sits in the shallow mini-horn used across AudioSolutions products. Low frequencies are reinforced by a high-flow reflex port whose flange is strongly rounded. The phase-linear crossover is assembled on an extra thick copper circuit board with high-grade air-core copper coils. Binding posts were redesigned for MK3 as large terminals in frosted satin silver that accept the thickest speaker cables. Buyers choose between gloss black or gloss white surfaces as standard, while Oak, Mahogany and Wenge wood textures are offered as options.

Pairing

A partner amplifier should stay comfortable with demanding loads and delivers the nominal power rating without strain, while the unclipped maximum sets the upper limit for its output.

Alternatives

The AudioSolutions Overture O322B sits one size up among the series' bookshelf speakers, with an 18.3 cm mid-bass driver and response down to 42 Hz.
