What reviewers think

Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.

What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

Reviews

SubmergeFound deep in the groves of your favorite LPs, and concealed in the soundtrack of the movies you can't wait to watch, is the critical low-frequency information that provides the the sense of space of the recorded music hall and the impact of the explosions the movie hero narrowly escapes. Submerge reveals the tension and sonic foundation below the surface of your audio experience. 

Advanced Enclosure TechnologyOur precision-engineered and handcrafted X-Material enclosures, paired with an S-Material front baffle, bring you a level of vibration control that's simply without equal in the center channel market. Every note, every whisper, every thunderous explosion is delivered with unparalleled clarity and authority.

Cutting-Edge HardwareThe 1,600 watt amplifier is uniquely mounted to the massive heatsink plate found on the rear of the enclosure. Coupling the amplifier to the T6061 Aluminum back plate efficiently transfers heat from the internal components of the amplifier to the decorative heatsink fins, the design of which is inspired by the mountain ranges surrounding Wilson Audio.

Remove the handcrafted front grille to expose the sleek aluminum baffle design. The attachment hardware for this mass of metal is strategically placed underneath grille post catchers, ensuring a clean and visually pleasing appearance without compromising functionality.

Taking a page from the Master Subsonic's playbook, the combination of thick X-Material as a substrate coalesced with the bulk of the aluminum baffle create a truly solid and extremely damped surface for the Submerge driver to be secured to.

Wilson Audio is often considered the quintessential American high-end hi-fi brand, a staple in premium audio dealerships across the country. Many reviewers use Wilson speakers in their own home systems, reflecting their reputation for outstanding dynamics, bass depth, and the ability to reproduce classical music with remarkable realism. Wilson focuses on creating an uncolored sound, aiming to replicate the experience of live, unamplified performances.

YG Acoustics
Basis
26648

Reviews

Basis shatters the notion that soundstage-enriching, deep and authoritative sub-bass must come from a large cabinet. Basis performs with the precision of a scalpel and the power of a sledgehammer. As a true ultra-fidelity subwoofer, Basis has huge bandwidth. It combines an entirely new, innovative driver, extreme cabinet engineering and an exceptional, wideband amplifier: Basis is capable of performing as nearly a full range speaker by itself.

When all of this capability is focused on the challenging and all-important sub bass region, the Basis proves its place well beyond the competition. Where other high-end subwoofers still struggle to avoid harmonic distortion, Basis delivers industry-leading behavior at the very lowest frequencies, with true fundamental bass for the discerning audiophile. It does this powerful work seamlessly, weaving bass energy into the expanded soundstage as if the Basis is an elemental part of the foundation.

Graceful curves and diminutive size belie an authority and strength we have only found to be bettered by our legendary Invincible subwoofer. For Basis, we incorporated a holistic design approach aimed at achieving the ultimate in high-end subwoofer performance. That we also achieved this in a compact package, one which can disappear sonically and visually in any listening environment, was a satisfying by-product of our process.

Listeners can enjoy a single unit, or stack multiple units in Duo or Trio configurations. This does much more than simply adding greater power: stacking loads rooms more evenly with bass energy, flattening modes more effectively than any other strategy. Basis lends beauty and soul to a reference-level system, delivering a meaningful improvement without adding any character of its own. Its quiet strength comes from thousands of hours of development focused on every single aspect of the design.

YG Acoustics makes speakers with unique DualCoherent crossover technology that ensures both perfect frequency response and phase coherence, while their BilletCore drivers are machined from solid aluminum billets for enhanced precision. Their modular design allows users to upgrade and expand their systems over time, and they use proprietary software that optimizes both frequency and phase response, capabilities not commonly found in other hifi brands.

  • Can smooth out the treble by providing a more solid musical foundation
  • Enhances subtle details in a recording
  • Provides tight and precise bass and the ability to reveal a wide gamut of textural colors
  • Integrates seamlessly into the system

Product Considerations

  • The single line LCD display and click/turn navigation rotary is a clunky, time-consuming method of accessing nested functions

  • Reviewer notes a sense of skepticism due to the amp being manufactured by Dayton Audio

Comparisons (according to reviewers)

  • LōKē is smaller than Wilson Audio's WATCH Dog
  • Compared to systems without a subwoofer, LōKē reproduces music otherwise unheard
  • LōKē, unlike the Wilson Audio WAMM Master Chronosonic subwoofer, has a built-in amplifier
  • Some reviewers feel that two JL Audio 12's provide a better value compared to LōKē

Takeaway: The LōKē is a well-built subwoofer that integrates nicely with Wilson Audio and other loudspeaker systems to provide a fast and coherent bass response. Adding the LōKē to an existing system enhances the musical experience.

  • Deep bass output and really good bass extension, with REL claiming -6dB at 15Hz
  • Exquisite paint finish with 12 coats of final lacquer applied, with each subwoofer taking 5 weeks in total to build
  • The remote control and digital display make it a very nice way of setting things up, and then after dialing in, the remote is probably not needed again

Product Considerations

  • It is a huge and very heavy subwoofer, weighing 85 kilograms
  • The handles on the side are useful for lifting such a heavy unit, but they are not very nice to look at

Takeaway: The No.32 is a top-of-the-line subwoofer that offers exceptional bass performance and exquisite build quality. It's perfect for audiophiles who want the very best and have the space to accommodate it.
