Полочная акустика — Q-Acoustics 3010c

The 3010c is the smaller of two stand-mount models in the 3000c family from British maker Q Acoustics, a range the company describes as an affordable entry point that builds on the earlier 3000i generation. It is a passive two-way bass reflex design meant for shelves, desks and small stands where a larger box would not fit. In the UK the pair lists at GBP 249, and the US price is USD 639 per pair. Buyers choose from Satin Black, Satin White, Pin Oak and Claro Walnut, and every version carries satin metallic trims around the drivers.

Key specs that matter

One 101 mm (4.0 in) mid/bass cone works with a 22 mm (0.9 in) tweeter, and the crossover hands over at 3.1 kHz. Q Acoustics quotes a frequency range of 60 Hz to 30 kHz at the -6 dB points. Nominal impedance is 6 ohm with a minimum of 3.7 ohm, and sensitivity is 85.0 dB measured at 1 m with 2.83 V at 1 kHz. The recommended amplifier range runs from 15 to 80 W. The cabinet has an effective internal volume of 4.5 litres and measures 254 mm high, 155 mm wide and 251 mm deep, with each speaker weighing 4.4 kg.

Engineering and use context

Q Acoustics designed the mid/bass unit from scratch around its C3 Continuous Curved Cone, a profile intended to help the cone blend with the tweeter near the crossover point. The tweeter is hermetically sealed and mechanically isolated from the baffle, so vibration from the neighbouring cone does not modulate it. Inside, Point to Point (P2P) bracing stiffens the panels at the spots most prone to low-frequency resonance rather than adding mass everywhere, which keeps the panels of the small box quieter. Each pair ships with two foam bungs for the reflex port, two grilles and an owner's manual. The US arm of the company lists a limited warranty of two to five years together with a 30-day return period.

Pairing

The sensitivity is on the low side, so an integrated amplifier delivering power near the top of the stated window is a sensible match in a room of about 20 m2. With a minimum impedance well under the nominal figure, the chosen amplifier needs to handle loads under 4 ohm without strain. Compact stereo amplifiers, streaming amplifiers and two-channel AV receivers whose output falls inside the maker's quoted range are all workable partners for this pair.

Alternatives

The Q Acoustics 3020c sits one step up as a bookshelf speaker in the 3000c range, fitted with a bigger mid/bass driver than the 3010c.
