Main features mentioned

• Self-powered design

  • Built-in amplification (everything integrated)
  • Built-in Bluetooth receiver
  • Includes its own wall plug

• Sound character

  • Praised rich mids and treble clarity (“Swan tuning”)
  • Surprisingly strong low end for a small speaker, especially when paired with a subwoofer

• Grille design

  • Transparent/see-through grills that let you view the drivers
  • Grille/removal and grille clearance can affect performance/space

• Connectivity / terminals

  • High-quality 5-way binding posts
  • Mentioned as non-magnetic
  • Supports banana plugs

• Form factor / setup tips

  • Placement advice: tweeter near ear height
  • If mounted too low, the reviewer suggests flipping the speaker upside down

• Bass integration expectation

  • Not intended for deep bass on its own
  • Reviewer strongly suggests adding/integrating a subwoofer for best results

• Requires power for performance

  • Claimed need around 150W per channel
  • Compared to Swan RB42 (~40W)

• Build / looks

  • “Dull” laminate/finish praised as among the nicest non-wood laminates
  • Heavy, solid binding posts; sturdy overall construction

Pros (user experience + performance)

• Very strong overall sound for the price (~$130)

  • Described as “the nicest” sound for “little speakers like this”
  • Noted repeatedly: vocal clarity and soundstage/presentation

• Low end improves significantly with integration

  • Reviewer says the speakers “scale” with better amplification
  • With a sub integrated, bass can sound coherent and even “as if coming from the speakers”

• Detail / accuracy

  • Revealing, useful for DAC/amplifier testing
  • Described as natural and not harsh
  • Mids and treble characterized as smooth/clean

• Better than comparisons at similar price

  • Claimed to surpass Swan’s RB 42 / MB 42 G2 in overall enjoyment
  • Those passives are framed as having more limitations/tradeoffs

Cons / drawbacks mentioned

• Grille performance/setup issue

  • Transparent grills still introduce a small acoustic/physical constraint in recessed placement
  • Reviewer calls them “infuriating”
  • He personally removes the grills for best audio quality
  • Example: an Amazon review gives 4 stars instead of 5 because you must remove the grills

• Binding peg vs magnets

  • Grilles use pegs rather than magnets, which the reviewer found surprising (even for cheaper brands)

• Not for deep bass by itself

  • Reviewer states they stop around roughly ~90 Hz without a sub
  • Without sub integration, low end is limited

• Placement affects bass output

  • Room/environment and positioning influence how much bass you can extract from the small ports

Comparisons made (key points)

• Edifier MR4 / similar under-$200 powered competitors

  • Swan Oasis 140 framed as a top go-to under-$200 powered choice

• Swan RB 42 (passive)

  • RB 42 described as having incredible low end, but requiring good amplification
  • Reviewer says Oasis 140 sounds nicer overall, with a win in vocals and soundstage
  • Power demand comparison in his experience:
    • Oasis 140: ~150W/ch
    • RB 42: ~40W

• Swan MB 42 G2 (~$100 class passive)

  • Praised as clean/respectable for ~$100
  • Reviewer suggests it may be better tuned than chasing ultra-low bass
  • Still, he says Oasis 140 leapfrogs them in enjoyment and performance

• Powered vs passive scaling

  • Central theme: despite being powered, Oasis 140 still “scale” dramatically with higher-end DAC/amp upstream
  • This scaling is contrasted with typical limitations of powered-speaker setups

Ratings / numbers explicitly mentioned

• Price paid: $114 (Prime sale mention)
• Current price noted: $130
• Amazon review example: 4 stars due to needing to remove grills
• Power requirement claim:
  • Oasis 140: ~150W per channel
  • RB 42: ~40W (as stated by the reviewer)
• Bass cutoff claim: stops around ~90 Hz without sub integration
• Scaling discussion references: expensive amplification/DAC examples are mentioned (illustrative rather than formal scoring), including Topping DX9 and Orchard Audio Star… Ultra

Overall recommendation / verdict

Buy the Swan Oasis 140 if you want unexpectedly “high-end” sound quality from a compact, self-powered speaker around ~$130—especially for vocals, treble clarity, and soundstage.

Best results come from proper placement and ideally integrating a subwoofer (otherwise you’ll miss the lowest bass). If you dislike removing grills and prefer magnetic attachment, that’s the main practical downside.
