Overview
The Tangent Spectrum II X4 bookshelf speakers are compact models from the Spectrum range, launched in 2014. This new generation incorporates technical improvements while retaining the brand’s signature minimalist, functional design.
A traditional acoustic design optimized for modern spaces
The Spectrum II X4 employs a classic yet effective two-way bass-reflex configuration. Its 25 mm dome tweeter and 10 cm paper-pulp mid-bass driver work together via a passive crossover set at 2800 Hz. This relatively high crossover frequency allows the bass driver to cover a wide portion of the midrange, ensuring tonal coherence for vocals and acoustic instruments.
Choosing paper pulp for the mid-bass cone reflects an acoustic approach that favors natural timbre over the pursuit of extreme performance. This material, used since the dawn of hi-fi, offers a balance of stiffness and internal damping that limits unwanted coloration. The rear bass-reflex port, sized to extend the response down to 65 Hz, offsets the physical limitations inherent to the cabinet’s compact volume.
The MDF cabinet, finished in a satin-matte coating, helps minimize parasitic resonances. Beyond its aesthetic appeal, the walnut-veneer plinth provides mechanical decoupling that limits vibration transfer to the supporting surface. This attention to construction detail also appears in the gentle waveguide around the tweeter, a subtle optimization that improves high-frequency dispersion.
The imprint of Scandinavian design applied to acoustics
Tangent, a brand founded in 1996 in the UK before its acquisition by Danish company Eltax in 1998 and then by the French group AV Industry in 2008, has gradually developed a strong visual identity rooted in Nordic design principles. This philosophy, defined by the pursuit of functional simplicity, is evident in every detail of the Spectrum II X4.
The permanently integrated micro-perforated metal grilles embody this approach, where protection and aesthetics come together without compromise. Available in satin black or white finishes, the speakers blend discreetly into contemporary interiors while maintaining a distinctive visual identity thanks to the contrast created by the walnut base.
This apparent simplicity conceals careful consideration of everyday use. The compact dimensions (145 × 256 × 198 mm) make placement on a shelf or desk easy, while compatibility with Tangent EVO wall mounts allows wall installation to free up floor space. Gold-plated screw terminals, compatible with banana plugs, reflect the intention to simplify connections while ensuring optimal electrical contact.
Versatile use designed for contemporary spaces
With a nominal impedance of 6 ohms and a sensitivity of 87 dB, the Spectrum II X4 is relatively easy to drive. This opens up many pairing options, from compact amplifiers in the Tangent Ampster line to more ambitious electronics. The power handling of 50 watts RMS (80 watts peak) and the recommended amplification between 20 and 70 watts confirm its universal vocation.
Reviews by the specialist press highlight a balanced presentation without excessive emphasis on any part of the spectrum. This relative neutrality, combined with good midrange definition, promotes clear vocal intelligibility and melodic line clarity. While the soundstage is limited in width and height by the speakers’ size, it still preserves a pleasing sense of depth at moderate volume.
Limits naturally appear under more demanding use. The small radiating surface and reduced enclosure volume impose physical constraints that even bass-reflex optimization cannot fully overcome. At high volume, midrange clarity tends to fade, and the bass, already limited in extension, may show signs of compression.
Seamless integration into the Tangent ecosystem
The Spectrum II X4 is part of a comprehensive range that allows gradual upgrades. The higher models X5 (with a 13 cm driver) and X6 (three-way floorstander) deliver extended performance for larger rooms. The XC center speaker, XSW8 subwoofer, and XATM Atmos modules enable a cohesive multichannel system.
This coherence extends to the brand’s electronics. The Ampster BT II amplifier, CD II player, and DAB+ II tuner share a common design language and can be controlled with a single remote. The resulting system, modest in size, forms a complete hi-fi setup suited to the constraints of today’s urban living spaces.
Bluetooth compatibility built into certain models in the range (such as the Spectrum X5 BT Phono) shows adaptation to contemporary use without abandoning acoustic fundamentals. This duality between tradition and modernity has characterized Tangent’s approach since its beginnings.

Frequently Asked Questions
What is the minimum distance to keep between the speakers and the rear wall?
The rear bass-reflex port ideally requires 20 to 30 cm of clearance to operate properly. Placement too close to the wall can overemphasize certain bass frequencies and create unwanted resonances. If space is tight, using Tangent EVO wall mounts allows optimal positioning with slight angling.
Are these speakers suitable for a home theater system?
The Spectrum II X4 can serve as surround speakers in a 5.1 or 7.1 setup, paired with the larger X5 or X6 models at the front. Their wide dispersion and tonal neutrality make them suitable for reproducing ambience. For a cohesive system, adding the XC center speaker and the XSW8 subwoofer is recommended.
What type of speaker cables should be used?
The binding posts accept cables up to 4 mm² or standard banana plugs. For short runs (under 3 meters), 1.5 mm² cable is sufficient. For longer runs, 2.5 mm² better preserves dynamics and definition, particularly in the bass.
Does the white finish yellow over time?
The satin-matte finish used by Tangent incorporates UV stabilizers that limit yellowing. Regular care with a slightly damp microfiber cloth is enough to preserve the original appearance. The natural walnut veneer base may darken slightly over the years, which is normal for this type of material.
How can I optimize placement on a desk?
For nearfield listening, the speakers should form an equilateral triangle with the listening position, slightly toed-in towards the listener. Isolation stands or acoustic foam under the bases minimize vibrations transmitted to the desk. Positioning the tweeters at ear height optimizes stereo imaging.
Can the Spectrum II X4 be paired with a tube amplifier?
The 6-ohm impedance and 87 dB sensitivity make pairing possible with moderately powered tube amplifiers (15–30 watts). The relatively stable impedance curve of this simple bass-reflex design eases the load on output transformers.
