Audiomania expert verdict

A compact, affordable Diamond 12 bookshelf: a 130 mm polypropylene driver and a 25 mm fabric dome in an 8.2 l box, 88 dB / 8 Ω (4 Ω minimum) — an easy load for any amplifier or receiver in an 8–18 m² room. Bass is limited (65 Hz) and the maximum is 96 dB: for deep bass and loudness you need a subwoofer or a bigger model. We have no listening evidence for this model yet. AI draft, under review

In brief

Best if you are looking for:

  • small rooms of 8–18 m² and shelves — a compact 18 × 31 × 28 cm, 6.8 kg box AI draft, under review
  • any affordable amplifier or AV receiver: 88 dB / 8 Ω (4 Ω minimum), by rule ≈ 35 W for 100 dB in 20 m² AI draft, under review
  • surround or front pair of a small multichannel set — stated for “stereo and multichannel systems” AI draft, under review
  • a long warranty — 36 months AI draft, under review

Keep in mind:

  • bass is shallow: 65 Hz (−3 dB) / 60 Hz (−6 dB) — bass-heavy music needs a subwoofer (crossover ≈ 85 Hz) AI draft, under review
  • maximum SPL 96 dB — not for loud parties or large rooms AI draft, under review
  • port position, terminal type, finishes and box contents are not stated on the card — check before buying AI draft, under review
  • no discussions and no text reviews — the sound character is so far described from the design only AI draft, under review

From the specialists' experience:

  • The maker allows “on shelves or dedicated stands”; until the port position is confirmed keep 30–50 cm from the rear wall.[2]

FAQ

›Which amplifier does it need?
88 dB / 8 Ω with a 4 Ω minimum is an easy load (1/10 by rule). The maker recommends 20–100 W; by rule ≈ 35 W is enough for 100 dB peaks at 3 m in a closed 20 m² room. Solid-state amplifiers, AV receivers and push-pull tube amps all fit.
›Will it work with an AV receiver?
Yes: 8 Ω nominal, 4 Ω minimum, an easy load — the description explicitly states compatibility “with a wide range of amplifiers and AV receivers”. For cinema — with a subwoofer (crossover ≈ 85 Hz).
›Do I need a subwoofer?
By rule (65 Hz at −3 dB, bass 3/10): recommended for music, required for cinema; crossover ≈ 85 Hz.
›Which room size does it suit?
By rule for a 130 mm bookshelf: 8–22 m², optimally 10–18 m²; the maker: “for small and medium rooms”. For larger rooms and loud listening look at the bigger Diamond 12 models.
›Do I need stands, and how tall?
Shelf or stands both work (“on shelves or dedicated stands”). By rule a 71–81 cm stand (tweeter at 95–105 cm seated), top plate from 11 × 17 cm; the Radiotehnika T7 (77 cm) fits.
›How close to the wall can they go?
The port position is not stated on the card, so the rule is conservative: 30–50 cm from the rear wall (20 minimum). Bass is modest — boom is unlikely; check the port position in the photos or the manual.
›Which cable?
By rule for 8 Ω (4 Ω minimum): 1.5 mm² up to 3 m, 2.5 mm² as standard, 4 mm² beyond 5 m. The terminal type is not stated on the card — check whether bananas fit.
›What is the warranty?
36 months (per the card).
›Does it need an amplifier?
Yes: these are passive speakers and need a stereo amplifier or receiver. See “Amplifier requirements” and “Recommended now”.
