Compare Sony SS-CS5M2 Bookshelf Speakers vs Kanto REN Speakers

Styling is simple and understated, with a matte-black look and a more refined front waveguide treatment than the older version. It is generally seen as plain but more polished than before.

The speaker appears easy enough to drive for ordinary AVRs and mainstream amps. Reviews cite a benign 6-ohm presentation and explicitly say expensive high-power amplification is unnecessary.

Digital format support is solid for mainstream use, especially with USB-C and HDMI ARC. A few reviewers flagged the 24-bit/96kHz USB ceiling as acceptable but not especially future-proof.

Bluetooth support is serviceable rather than class-leading. AAC support is fine for casual streaming, but some reviewers noted the lack of higher-end codec support.

Bluetooth playback is reported as stable, with reviewers mentioning smooth pairing and no meaningful dropouts in normal use. The limitation is more about codecs than connection reliability.

Build quality is repeatedly described as strong for the class, with decent cabinet feel, useful bracing updates, and a more thoughtfully executed budget crossover than many cheap rivals.

The M2 is generally described as more mature, smoother, and more coherent than the original, with fewer tonal distractions, though budget limits still show up in scale and dynamics.

Several reviewers highlight how cohesive and orderly the REN sounds, even on dense mixes or movie soundtracks. It presents a unified stereo image rather than a disjointed hi-fi effect.

The cabinet is slim, visually easy to place, and more modern-looking than the prior version, though the overall presentation remains budget-minded and not luxurious.

Reviewers consistently praise the REN's matte finishes, curved cabinets, color options, and living-room-friendly look. Minor knocks are fingerprint and scuff sensitivity on the matte finish and a few comments that the styling is softer or rounder than some rivals.

Detail is good for the class rather than elite, with solid transient information and improved midrange clarity when the speaker is high-passed or paired with a subwoofer.

Detail retrieval is strong for the class, with reviewers noting good low-level insight and clear rendering of vocals and instrumentation. A few higher-end comparisons say it stops short of pricier speakers, but it rarely sounds vague or smeared.

Dialogue clarity is consistently strong, both in normal playback and with the optional Vocal Boost mode. Reviewers found speech easy to follow in films, TV, sports, and documentaries.

Reviewers found it surprisingly clean for its size, with some tests showing little obvious distress, but compression and grain can emerge near its limits or when it is run full range without a subwoofer.

The REN generally stays clean, but several reviewers noticed bass strain, port noise, or low-end looseness when it is pushed hard without a subwoofer. Using the sub output and 80Hz crossover reduces that behavior substantially.

Dynamic headroom is acceptable for moderate rooms and casual theater use, but the speaker shows its size limits with compression and reduced bass authority as playback levels climb.

Dynamics are good for a compact powered speaker and improve meaningfully with a subwoofer connected. At higher output the REN can sound a bit held back compared with larger systems, but it remains lively for TV, gaming, and moderate-room music listening.

Bass and treble controls, Vocal Boost, and Night Mode add welcome flexibility. These features are useful rather than gimmicky, especially in TV use or when tailoring bass around a subwoofer or room placement.

The general consensus is that the M2 is smoother and more neutral than the original SS-CS5, with tamer upper treble and respectable midrange balance, though bass remains limited and minor treble or upper-mid quirks persist.

Most reviews describe the REN as balanced, neutral-leaning, and easy to listen to, with smooth treble and clear mids. The recurring caveat is the bass, which some heard as a little lumpy, boomy, or uneven depending on placement and volume.

HDMI ARC is repeatedly cited as the REN's signature feature, making TV hookup simple and helping it behave more like a polished soundbar alternative. ARC and CEC control were widely appreciated, though some setups required switching the TV to PCM.

These speakers fit budget home theater use well, whether as mains, surrounds, or even height channels, especially when paired with an AVR and crossed to a capable subwoofer.

As a TV and movie speaker system, the REN earns strong marks for combining true stereo separation, easy ARC hookup, and optional sub integration. Reviewers broadly agree it outperforms similarly priced soundbars for fidelity, though it remains a 2.0 or 2.1 solution rather than surround.

The active-passive speaker arrangement is straightforward, and the ability to swap which side is powered is genuinely useful for room layout. Included speaker cable length is generally seen as sufficient and flexible.

The SS-CS5M2 plays louder than many expect from a small budget bookshelf, but it is not an output monster and loses authority when asked to deliver big full-range bass at higher levels.

Output is adequate to strong for typical living rooms, desks, and nearfield use, but it is not a room-shaking SPL monster. Reviewers wanting party-level volume or bigger effortless slam consistently preferred adding a subwoofer.

The single front knob handles core tasks cleanly, but on-speaker controls are intentionally basic. Most reviewers were fine with that because the remote or TV remote handles deeper control.

Price sentiment is highly dependent on street price. The speaker is repeatedly praised when discounted into the 150-dollar range, while full MSRP around 250 dollars is often treated as a tougher sell.

The remote is feature-rich and usually considered better than average for the category, with quick access to inputs, bass and treble, sound modes, and speaker-side swapping. Common complaints are that it is chunky, batteries are not included, and responsiveness can occasionally feel slow.

Setup is straightforward by passive-speaker standards: reviewers describe easy integration with common AVRs and small amps, especially in budget stereo or theater systems.

Setup is widely described as plug-and-play, especially for HDMI ARC TV use. The main caveats are the need to place the speakers thoughtfully, sometimes change TV audio settings to PCM, and understand the left-right speaker swap behavior.

Auto-wake, Vocal Boost, Night Mode, sub mute, and other DSP conveniences help the REN feel thoughtful in everyday use. These extras strengthen its TV-first appeal without requiring an app.

One review specifically called out surprisingly convincing apparent height along with width and depth when the speaker was positioned properly near tweeter level.

The front LED and input indicator are helpful and brightness-adjustable, with reviewers appreciating the ability to dim or disable them. It is a small but polished usability touch.

Imaging is a genuine strength for the price, with reports of precise placement, good center focus, and speakers that disappear well, even if they do not match the depth or holography of pricier models.

Stereo imaging is one of the REN's standout strengths. Multiple reviews call out strong left-right separation, stable center images, and a wide soundstage that makes it a convincing soundbar alternative.

A subwoofer is strongly recommended. Multiple reviews say the speaker works much better when crossed around 80 to 120 Hz, which improves bass weight, detail retention, and dynamic composure.

Value for money is one of the strongest themes in the reviews, especially when the speaker is on sale. At full MSRP the value is still decent, but no longer obviously class-leading.

Value is a consistent strength. Most reviewers see the REN as expensive only relative to cheap soundbars, but very competitive once sound quality, inputs, and TV-friendly features are factored in.

Vocals are generally clear and centered, with better tonal behavior than the older model, but a few reviewers still heard mild sibilance or forwardness on certain voices and recordings.

Its slim cabinet and roughly 9.5 to 10 lb weight per speaker make it relatively easy to place on shelves or use in surround and height roles, though it is not unusually compact.

As a conventional passive speaker, it offers standard rear binding posts that reviewers considered decent for the price, though one review noted banana-plug insertion depth could be better.

Connectivity is a major selling point, with HDMI ARC, optical, USB-C, RCA, 3.5mm, and sub out appearing in nearly every review. The only recurring omissions mentioned are a built-in phono stage and Wi-Fi streaming.
