Compare KEF LSX II Wireless HiFi Speakers vs Fluance Ri71 Reference Powered Bookshelf Speakers

On-device controls were a clear weakness because direct mentions complained about the lack of on-speaker touch or physical controls.

On-device controls were divisive: some found the top/rear volume control substantial and accessible, while others disliked its placement, speed, or learning curve.

Smart features were viewed as broad and convenient, especially streaming services and app control, though Roon and multi-room gaps reduced perfection.

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

EQ customization was praised for room, placement, treble, bass, and subwoofer tuning, with one caveat that full manual EQ control is limited.

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

The optical input produced pleasing results in the one direct listening test that evaluated it.

The missing optical input was one of the most repeated connectivity complaints, especially for older TVs, PCs, and comparison with related models.

Setup simplicity was a strong point, with repeated reports of smooth app setup, quick connection, and minimal fuss.

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

Value was strongly positive overall because reviewers framed the speakers as a compact, musical, feature-rich all-in-one system that competes well for the money.

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

Remote opinions were mixed to negative: one reviewer liked the ergonomics, but others called it cheap, plasticky, limited, or only situationally useful.

Remote usability was mostly praised as handy and useful for daily control, but one reviewer found the mirrored bass/treble layout unintuitive.

Amplifier integration drew strong praise where evaluated, with reviewers saying the amps are well matched or fine-tuned to the drivers.

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.

High-volume behavior was mixed: some heard little distortion, while others reported brightness, strain, hardness, or stridency near the top of the volume range.

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

The compact footprint made the system easy to move between rooms in the one direct portability-related mention.

Reviewers who discussed size and weight found the speakers manageable for desks, stands, shelves, TV consoles, or ordinary living spaces.

Cohesion was praised across listening notes, with reviewers describing organized, tight, musical, and speaker-disappearing presentations.

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

Vocal clarity was praised in most direct mentions, although one comparison found intelligibility less strong than a competing setup.

Voice clarity was praised in music and vocal-centric content, with vocals described as natural, clear, centered, and detailed.

HDMI ARC was useful for TV integration and convenient control, but one reviewer criticized the lack of eARC.

HDMI ARC was praised as a major TV-use convenience, but evidence was mixed because some reviewers encountered picky behavior or low output.

Cabinet build quality was positive in the direct evidence, with the speakers feeling solid and dependably made.

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

Detail retrieval was a consistent strength, with reviewers emphasizing clarity, separation, transparent presentation, and the ability to pick out instruments.

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

Dynamic performance was strong for the size, with punch and liveliness repeatedly praised, though ultimate scale still depends on room size and bass demands.

Dynamic range was generally praised as solid or very good for the class, especially within reasonable room size and volume expectations.

Home theater integration was generally good for stereo TV use, dialogue, and separation, but not ideal for full surround immersion or heavy bass scenes without a sub.

Reviewers broadly supported the Ri71 as a TV/soundbar alternative, while still treating it as stereo enhancement rather than full surround home theater.

For TV and dialogue, reviewers generally heard clearer, more forward voices, though one comparison preferred another system for vocal intelligibility.

TV dialogue evidence was consistently positive, with speech described as centered, clear, intelligible, and easy to follow.

Inter-speaker connectivity was mixed: wired links can improve sound or simplify LT power, but some reviewers disliked losing wireless inter-speaker freedom.

Inter-speaker setup evidence was mixed: standard wire and channel swapping were useful, but raw-wire handling drew criticism.

Reviewers found the speakers surprisingly loud for their size in small to mid-size rooms, but several noted limits when pushed hard or used in larger spaces.

Loudness was considered sufficient for small-to-medium rooms and TV use, though reviewers cautioned against expecting party-speaker output.

Tonality was generally described as balanced, inviting, and detailed, though a few reviews noted treble brightness or placement-sensitive bass.

Frequency balance was widely described as neutral, well-balanced, controlled, and suited to many genres, with only minor caveats around bass or midrange voicing.

Low-volume evidence was mixed: one reviewer felt dynamics dropped when set too low, while another still felt bass at lower volumes.

Low-volume evidence was positive, noting retained body, presence, and detail in quieter listening or scenes.

Wired connectivity was a major strength, with reviewers praising the breadth of physical inputs including USB, optical, HDMI ARC, analog, and network options.

Wired-input evidence was mixed: RCA/HDMI flexibility helped, but limited USB, optical, and broader digital input options were recurring drawbacks.

Bass was repeatedly called impressive for the size, but reviewers also agreed deep bass, EDM, movies, and large rooms benefit from adding a subwoofer.

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

Soundstage height was excellent in the two direct nearfield mentions, with the stage extending above and behind the speakers.

One reviewer specifically praised perceived soundstage height along with stereo separation.

Off-axis and room coverage were strong in the few direct mentions, with reviewers praising sound quality away from the sweet spot.

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

Audio format support was broad, but reviewers noted that higher native resolution playback depends on wired connections.

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

Stereo imaging was one of the clearest strengths, with repeated praise for centered vocals, detached images, broad staging, and precise placement.

Stereo imaging was repeatedly praised, with reviewers noting centered vocals, wide soundstage, precise placement, and convincing left-right motion.

Design and aesthetics were one of the strongest areas, with reviewers repeatedly praising the styling, compact form, and luxury or décor-friendly look.

Design reactions were mixed-positive: several liked the attractive, functional look, while others called the finish old-fashioned or not visually subtle.

AirPlay worked smoothly in the one opinionated mention, with the reviewer switching without failure.

Chromecast was the main casting weak spot, with one reviewer reporting unusually slow track loading.

Button and knob response was split: one reviewer praised clicky positive remote buttons, while another disliked the feel and speed of the volume control.

Status indicator evidence was mixed-positive: dimming and shutoff were appreciated, but one reviewer found the LED much too bright.

The app was widely praised for being easy, responsive, and usable, with only minor reservations around layout or specific streaming behavior.

Bluetooth codec support was praised for aptX HD/AAC quality, although some reviewers noted rivals or other codecs can offer different advantages.

Bluetooth pairing and everyday wireless use were described as easy, reliable, or effortless across the supporting reviews.

Bluetooth range received a qualified assessment because the older Bluetooth version made the reviewer wish for Bluetooth 5.0 range benefits.

The main multi-room limitation was that synchronized multi-room playback was not available in the KEF Connect app.

Wireless and streaming reliability was mostly positive, with smooth Tidal, AirPlay, and network use, though one Roon/MQA experience included dropouts.

TV latency was consistently positive in direct tests, with reviewers reporting no syncing issues or virtually no lag.

Surround immersion was a weakness in the one direct mention, with the speakers not delivering Atmos-style or DTS:X-like effects.
