Closer Acoustics has dedicated a decade to what it describes as "the purest expression of music" through wide-band driver-based loudspeakers. This has now culminated in launching its new Blocks modular speaker system—an innovative, flexible way to achieve "outstanding sound tailored to different tastes, room acoustics, and amplifier types."
The Blocks system is based on Closer's OGY standmounter, a 10 cm full-range driver (8 Ohm, 15W, 91dB efficiency) in a transmission line enclosure, and BOB (Bass Open Baffle) bass modules. These are joined by OKHO, a wide-band speaker designed to bring "depth, clarity, and natural musicality" and features an EMS 12-inch (30.5 cm) wide-band driver, previously featured in Closer Acoustics' flagship Vigo.
The Polish brand states that OKHO sports a dual diaphragm in an open U-shaped enclosure engineered for high efficiency (97.5 dB) and a resonant frequency of 34Hz, making it an ideal match for open-baffle designs.
Closer tells us that, unlike traditional multi-driver speakers relying on crossovers that can introduce phase distortions, OKHO's single-driver design ensures a cohesive and highly natural sound reproduction.
Closer Acoustics has also fine-tuned its Bass Open Baffle unit (8 Ohm, 100W, 94dB efficiency) to create BOB MKII. Thanks to their open-baffle design, BOB modules promise to prevent unwanted booming while enhancing the 40–200 Hz range.
The upgrades include removing the terminal with an inductive coil in favour of a higher-quality individual coil integrated with the driver. Meanwhile, the speaker terminals are now high-grade pure copper units compatible with spades, bananas, and bare wire. BOB MkII also benefits from Cardas' 9.5 AWG pure copper internal wiring. Finally, acoustically transparent fabric has been added to the module's rear for dust protection.
Rounding off the system is Blank, an empty enclosure that raises your chosen configuration to the ideal listening height. Finally, all modules can be placed on a Platform with ISO Acoustics GAIA II anti-vibration feet, further enhancing sound precision.
Closer suggests the following module combinations:
- Smaller Room: Blank → BOB → OGY (€6.490)
- Basic Setup: Blank → BOB → OKHO (€7.210)
- Maximum Bass Reinforcement: BOB → BOB → OKHO (€9.350)
- Large Room Configuration: Blank → BOB → OKHO → BOB (€10.093)
Regional pricing has not yet been confirmed as the Blocks system is offered directly from Closer Acoustics.
