Closer Acoustics is a small Polish maker of high-efficiency loudspeakers and tube electronics, run from Katowice by brothers Jacek and Andrzej Grodecki, with Jacek as founder and CEO. Everything is built by hand in its own workshop in Poland. The company is known for single-driver speakers without crossovers, for offering many models in 8 or 16 ohm versions, and for designing amplifiers meant to drive them.
Range & what it's known for
The OGY was the first stand-mount. It uses one 10cm EMS LB5 wideband driver handmade in France, loaded by a transmission line in a cabinet of about 6 litres, with no crossover in the signal path, 92dB efficiency and 40Hz to 18kHz response. Larger floorstanders follow the same idea for owners of low-power amplifiers. The modular BLOCKS system combines interchangeable elements such as the BOB and OKHO units. On the electronics side there is the 300B Provocateur integrated amplifier, the Flō phono stage and a power supply, all built around tubes and a simple signal path. Closer Acoustics also distributes EMS field-coil drivers from France and takes custom commissions.
Who owns it and where it's made
The firm is privately owned and family run by the Grodecki brothers. Design, cabinet work, assembly and the building of amplifiers take place in the Polish workshop rather than at a contract factory. Drivers come from the French specialist EMS, which supplies the wideband units used across the speaker range.
The lineup in this catalog
Floorstanders including the Adam, Eva, Allegra, Forlane and Vigo, the compact Ogy stand-mount, the Flō phono preamplifier offering both balanced and single-ended inputs and the 300B Provocateur Signature Edition integrated amplifier. The Adam and Eva share a 117cm cabinet weighing 43kg and need only about 35W.
Who it's for
Closer Acoustics designs its speakers for systems built around single-ended or other low-power tube amplification. In a small room the Ogy comes first, with a move to a floorstander, then the Provocateur amplifier and Flō phono stage, giving a complete system from one workshop. The 16 ohm option matters for owners of amplifiers with matching output taps.
