Smart-feature evidence was limited and mixed: reviewers disliked the lack of phone/app control, while one appreciated that no app was required.

Cabinet construction is praised for inert, well-braced, refined build that supports low coloration.

Cabinet build was mostly praised as solid, dense, sturdy, or better than expected, with one reviewer calling the class-average construction less substantive.

High-volume cleanliness is mostly praised, though one synthesis review warns control drops at concert-hall levels.

Most reviewers found the Ri71 clean at normal-to-loud levels, but several noted honkiness, edge, harshness, or limits when pushed very hard.

Setup evidence is polarized: many reviewers call it easy or guided, while others find the initial app/Google Home process frustrating.

Setup was consistently described as easy, straightforward, plug-and-play, dead simple, or hassle-free.

EQ and room-tuning controls are praised for allowing meaningful bass, treble, room, and subwoofer adjustments.

Bass/treble tone controls were viewed as useful for tailoring sound, though some reviewers found the adjustment system basic or rudimentary.

Reviewers consistently describe the presentation as integrated, cohesive, and naturally held together.

Reviewers described the Ri71 as musically confident, cohesive, polished, and engaging, while one Bluetooth rock comparison produced a more mixed result.

The built-in amplification is presented as a major convenience because buyers do not need to match the speakers with a separate amplifier.

Reviewers who discussed power felt the built-in amplification saved space and provided enough drive for the Ri71’s intended small-to-medium-room use.

Value evidence is split but broadly positive: many reviewers call the performance strong for the money, while some prefer cheaper separates or alternatives.

Value evidence was very strong overall, with reviewers repeatedly saying performance, features, and sound quality punch above the price, despite connectivity tradeoffs.

Subwoofer evidence is context-dependent: some reviewers say the speakers do not need one for music, while movie or bass-focused setups benefit from adding one.

Subwoofer support was considered valuable, both for deeper bass and for relieving the speakers of low-frequency strain.

Detail retrieval is one of the strongest themes, with reviewers repeatedly hearing fine texture, layering, micro-detail, and clarity.

Detail retrieval was one of the strongest themes, with reviewers repeatedly praising AMT treble clarity, nuance, texture, and high-frequency insight.

Bluetooth codec support earns positive evidence from aptX playback being judged high quality despite Bluetooth’s lossy nature.

High-resolution format support is generally viewed as useful and broad, though one reviewer heard no practical difference between very high sample-rate files.

The only opinionated format evidence says the simple stereo format should sound natural with most content rather than chase surround formats.

Dispersion and sweet-spot evidence is positive, with Uni-Q/coaxial design helping wider seating and room coverage.

One measured/listening review praised wide, even coverage, supporting a broad listening area rather than a tiny sweet spot.

Review evidence praises the expanded finish choices and treats the new colors as a visual upgrade rather than a functional change.
