Passive, and meant for a stand rather than a desk
These are the passive speakers a living-room system is built from — not the powered monitors of a desk, which belong to another catalogue entirely. The reason to choose one over a floorstander is placement: a small cabinet on a stand puts the tweeter at ear height, which is where imaging comes from, and it asks far less of the room. What to read: frequency response with tolerance, and no expectation of deep bass — a well-made 15 cm two-way reaching 50 Hz honestly is worth more than one claiming 35 Hz without saying at what tolerance. Then sensitivity and impedance, and the port again, since a bookshelf speaker is far more likely to end up close to a wall. We compare stated frequency response with tolerance, sensitivity and impedance, driver sizes, port placement, and cabinet dimensions.
Passive pair · 100 W · 8 Ω stated · full-range mini cube · for home cinema, stereo or office
The cheapest speaker in this catalogue: a full-range mini cube that publishes its impedance, which is the one figure that decides compatibility.
Best for: Rear or height channels in a system that already has a subwoofer, at the lowest possible cost.
≈ $40 / £31 / 25 €
2-way · 60 W RMS (120 W peak) · 4–8 Ω · 88 dB sensitivity · 110 mm woofer-mid, 13 mm tweeter
The only bookshelf speaker in this catalogue that publishes RMS power, impedance range AND sensitivity — the three figures that decide whether an amplifier suits it.
Best for: Anyone matching speakers to an amplifier on published figures rather than on brand.
≈ 135 €
Passive pair · 2 × 30 W · 6 Ω impedance · 40 Hz–20 kHz stated · carbon fibre dual drivers
A compact pair that publishes impedance and a frequency range — 6 Ω and 40 Hz to 20 kHz — at a price where nothing else does.
Best for: A small system where the amplifier is modest and the impedance needs to be uncomplicated.
≈ £70 / 60 €
Passive pair · two-way · balanced tuning · fourth generation of the range
The compact member of the Ultima range, which also supplies the centre and the active floorstanders in this catalogue — matching is the argument.
Best for: The rear or front pair of an Ultima system, matched to the Ultima centre.
≈ 220 €
Passive pair · compact · from the Reference range
A passive compact speaker from a house built on horn loading and high sensitivity — neither of which this listing states.
Best for: A Klipsch system, where the subwoofer and height modules from the same range are already in place.
≈ £302 / 278 €
