Полочная акустика — AudioSolutions Overture O322B

The Overture O322B is the larger bookshelf speaker in the Overture MK3 range from AudioSolutions of Vilnius, Lithuania, which the company presents as its third-generation entry-level line. Founded in 2011 by speaker engineer Gediminas Gaidelis, AudioSolutions makes its products by hand in its own workshop and keeps annual production to roughly 500 pairs. Compared with the MK2 predecessor, cabinet, drive units and crossover were all designed anew. The series also contains the smaller O302B, the O301C and O311C models and the O303F, O304F, O305F and O306F.

Key specs that matter

Two drivers form a two-way system - a customised silk dome tweeter above an 18.3 cm mid-bass driver with an ER paper cone, divided at 3,000 Hz. Measured in a room, response runs from 42 Hz to 26,000 Hz. Sensitivity is 91 dB at 2.83 V and 1 m and nominal impedance is 4.0 ohm, while power handling is rated at 80 W RMS and 160 W maximum. The enclosure measures 424 mm in height, 250 mm in width and 390 mm in depth. Net weight is 14 kg per speaker and the shipping weight 19 kg.

Engineering and use context

AudioSolutions builds the cabinet with its Sectional-Box-in-a-Box structure, shared with the Virtuoso series, pairing a light internal shell with a heavier outer shell and filling the gap with polyurethane to absorb the vibration that would otherwise travel into the walls of the box. ER stands for Extra Rigid, the cone treatment the brand developed for its Figaro speakers. A mini-horn surrounds the tweeter dome, a detail the maker applies across its ranges to lower distortion. Air leaves the box through a high-flow bass reflex port finished with a generously rounded flange. The crossover follows a phase-linear layout, built on a thick copper PCB with coreless copper coils. Connection is made through heavy binding posts in a frosted satin silver finish sized for thick high-end cable. Carpet-piercing spikes are part of the package. Five finishes are listed - Gloss Black, Gloss White, Light Oak, Mahogany and Wenge.

Pairing

The O322B suits amplifiers specified for low-impedance operation, and its RMS rating gives a guide to the continuous output worth having available, with the maximum figure as the ceiling the drivers are rated to accept. Its sensitivity rating sits 1 dB above that of the O302B, so for a given level it asks slightly less voltage from the amplifier than its smaller sibling.

Alternatives

The AudioSolutions Overture O302B is the smaller stand-mount alternative in the Overture MK3 line, with a 15.2 cm mid-bass driver in a 9 kg cabinet.
