Column G70

Overview

The Revox Column G70 is a slim, two-way floor-standing bass-reflex loudspeaker from the G series, designed with minimal visual footprint yet detailed sound reproduction. According to Revox’s technical documentation, the cabinet measures 1,112 × 104 × 104 mm (H×W×D) and weighs 8.7 kg. The speaker uses a D’Appolito driver arrangement to achieve symmetrical radiation, as stated by the manufacturer.

Key Features

• Driver configuration: 2-way system with bass-reflex support and D’Appolito chassis arrangement for horizontal coverage across the full frequency band.

• Technical specifications (from Revox):

  • Nominal impedance: 4 Ω

  • Sensitivity (efficiency): 87 dB at 1 m / 1 W (2.83 V)

  • Frequency range: 42 Hz – 30 kHz

  • Recommended power handling: 100 W

• Compact footprint: With only 104 mm width and depth, the Column G70 fits into narrower spaces than typical tower speakers, making it suitable for contemporary interiors. (Data per manufacturer.)

• Finish/varieties: Available in colours including black, silver/black, and white.

Sound

Based on the published specs and Revox’s design intent, one can infer that the Column G70 aims for full-range musical reproduction with studio accuracy (as per Revox’s “true studio sound quality” claim).  The D’Appolito arrangement suggests improved mid/tweeter dispersion and soundstage uniformity across a room. While sound is inherently subjective, users should expect:

• Clear midrange and vocals (thanks to the balanced driver placement)

• A frequency reach down to ~40-42 Hz that allows respectable bass performance for its size

• A sensitivity of 87 dB means moderate amplifier power will suffice for typical listening rooms, but pairing with a high-quality, low-distortion amp will yield best results

• Because the design emphasises studio-like clarity rather than extreme “boom”, bass extension and room integration will still depend significantly on room acoustics and placement

Usage

• Ideal setup: Use as the main stereo channels in a 2.0 or 2.1 music system, or as front left/right in a home cinema rig.

• Amplifier matching: With 4 Ω impedance and 87 dB sensitivity, selecting an amplifier rated for at least 50-100 W into 4 Ω will ensure headroom and dynamic capability.

• Room size & placement: Given the slender cabinet and ~42 Hz low-frequency limit, the Column G70 is well suited to small-to-medium sized listening rooms. If your room is large or you demand deep bass, consider supplementing with a subwoofer.

• Aesthetic & installation: With its narrow footprint (104 mm width/depth), the speaker integrates cleanly in modern décor. Because of the bass-reflex design, allow some clearance behind the speaker for optimal low-frequency performance.

• System integration: As part of the Revox G-series ecosystem (amplifiers, network receivers, etc.), it pairs especially well with other Revox components for coherence in design and tone.
