Quad S-1

The reviewer is unequivocal that there is very little bass and says a subwoofer is essential for listening. That is a significant limitation even for this very small, vented 4-inch design.

The midrange earns especially strong praise for sounding luscious, organic, and nicely bloomed. The reviewer also highlights convincing texture and reports no complaints in this region.

The ribbon/AMT-style treble is described more as a matter of taste than as an unqualified strength or weakness. Review evidence suggests it will appeal to listeners who enjoy this presentation, but offers little detail on its refinement or tonal balance.

For close-up listening, the S-1 is said to image on a notably large scale, with spaciousness, depth, and sounds projecting well into the room. Those strengths are most convincing at a two-to-three-foot desktop distance rather than across a larger room.

The low sensitivity makes these among the more difficult speakers the reviewer has driven, with real-world sensitivity suggested to be lower than the published figure. They are not intended to deliver room-filling output, so amplifier matching and nearfield use matter.

The compact cabinet is praised for its attractive wood veneer, and the ribbon tweeter looks more substantial than expected for such a small speaker. Reviewers say little about cabinet resonance, crossover components, terminals beyond bi-wiring, or long-term durability.

Value depends heavily on market: the reviewer notes a roughly $1,000 US price, about double the cost in many other countries, and does not consider it among the best values for US buyers. At that price, the need for a capable amplifier and a subwoofer further strengthens the case for comparing alternatives.
