In a world where subwoofers are big and often not too appealing to the eye, the Subissimo is an unobtrusively elegant and adaptable solution to the challenge of reproducing full-range music at home. Used individually or in pairs, it integrates as perfectly with the Arabesque Minissimo as it does with your home décor.
Development
At the same time that we were developing new innovations for the Arabesque Minissimo, we were also working on the revolutionary sub-bass system that would become the Subissimo. We were determined to make these two ground-breaking products integrate simply and seamlessly. A subtle machined rebate in the speaker's base accepts a specially selected compliant mat, sealing the downward firing port and perfectly tailoring the Arabesque Minissimo's response for use on a she...

Our take on the brand
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.
Our summary
Product Strengths
- Enhances room pressurization and provides a sense of the recording's space
- Adds texture to both low-frequency and mid-range sounds, significantly enhancing the listening experience
- Improves deep bass and addresses room-related issues
- Flexibility helps to recover low octaves, ensuring the subwoofer matches the measured response
Product Considerations
- High price point
- The unit is very heavy, weighing just over 115 kilos (250 pounds)
- Requires careful setup involving the crossover, gain, and phase/delay to achieve perfect time alignment
Comparisons (according to reviewers)
- Builds on the success of the smaller Wilson Audio LōKē Powered Subwoofer
- Includes the same proprietary driver found in the Wilson Audio Subsonic Subwoofer
- Features a built-in crossover inspired by the Wilson ActivXO crossover
- Bigger than the Loke, with a larger cabinet and woofer, and increased amplifier power from 500 to 1,600 watts
- The WATCH Dog has a split port with a divider, but in the Submerge, the split is pushed back to improve airflow and quieten the cabinet
Takeaway: The Wilson Audio Submerge provides a more immersive listening experience by adding depth, texture, and improved bass response, making it a worthwhile addition for high-end hifi systems, especially when paired with Wilson Audio speakers. Its ability to address room acoustics and provide a balanced soundstage makes it a valuable addition.

Our take on the brand
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.

Our take on the brand
What competes at this price?
Our Summary
Product Strengths
- Enhances the venue in which a recording was made
- 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
- The different parameters of the sub are on the back and controlled from the back, which means that users may have to keep pulling it in and out of position for each parameter change
- 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.

- Response is flat down to 20Hz
- Sound quality improves in areas that have nothing to do with bass, and everything brightens up
- Immediately balanced and sophisticated sound
Product Considerations
- Some tweaking with regards to the positioning of the speakers is needed to get the best from the soundstaging
- The full manuals are online or to print off, which some may find a pain

Video review
Our take on the brand
Our Summary
Product Strengths
- Described as a 'real beauty', it is the new reference top-of-the-range flagship subwoofer from REL
- 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.
