What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
Product Strengths
- The app allows control of up to eight subwoofers at one time
- The Bluetooth app is fantastic, easy, and straightforward
- Delivers bass with alacrity
- Has provisions for firmware updates
- Has both line-level and speaker level inputs, allowing for more installation options
Product Considerations
- To set up the RS500, the ELAC app must be used; if a smartphone isn't available, crossover settings can't be adjusted since there's no adjustment knob on the cabinet itself
- At 20.3kg (just under 46 pounds), the RS500 isn't light, and reselling subwoofers has the problem of shipping cost
Comparisons (according to reviewers)
- Vs Klipsch RP-1200SW: The RP-1200SW may offer a bit more boom for a bit less money, has wireless connection options and easy-to-read calibrations on its volume and crossover controls, but lacks any speaker-level inputs and app
- Vs JL Audio E series: The E series only has line-level inputs and no app
- Vs REL T/7x subwoofer: The REL T/7x subwoofer would be a room-friendly option because of its compact form factor, but it does not have a dedicated app
Takeaway: The Varro subwoofer seems to deliver great bass and has a good app to change the settings easily. This could be a good option for those seeking a subwoofer with good performance and easy control.

Our take on the brand
Classic 99
Nothing Continues to Says Lifestyle like Mid-Century Modern RELs
Classic 99 extends our Classic Line to loftier heights. Richer, bolder, and more powerful? Certainly. Yet 99 is also capable of far greater nuance, air, and resolution than its lesser brethren. For those with more capable systems and larger rooms, Classic 99 delivers advances on every front, while still maintaining the same easy-going, room-filling nature all Classic offerings possess. The high-grade genuine dark walnut veneer complements a variety of decors. Classic 99 delivers this in the same simple, comforting form of Mid-Century Modern design. Perfect for those who welcomed the original, yet were waiting for the next chapter to be written, those who crave even higher performance and the ability to fill larger, grander spaces with a broad carpet of deep bass. You'll still want to put on a record, pour a favorite drink, sink into your favorite chair, and relax into the music or movie of your choice. Classic 99, for those who waited for more.
Designed to Be Superior
Classic 99 adopts the form language introduced in its model 98 stablemate. As comfortable as a pair of well-worn loafers, it features solid cabinet walls as thick as 32 mm, clad in rich, warm walnut veneer, hand fitted with care. The simplest of natural aluminum badges and softly radiused feet milled from solid billet, blacked out to allow it to seemingly float, ensure that nothing, not even a grille disturbs the vibe. Yet, as with all RELs, the styling conveys far more than simple comfort. The down-firing 12" driver, while unseen, will surely be felt. Continuing to the rear panel, one finds the period-correct detailing extends to the amplifier panel, where all controls are finished in lovely white gold. Everything that one encounters has the heft of quality switch gear, even the click made by the phase switch is near perfection. Quality abounds everywhere one looks or touches. Don't be surprised if your children fight over it later in life.
Driven to be Louder. And Quieter.
As anyone familiar with REL will tell you, we always begin with the driver. In this case, a bespoke 12" long stroke driver that uses lightweight, stiff, hot-pressed paper to form the main body of the cone. Laid atop that is a stiff center cap made of hand-thrown paper; to randomize the fibres, ensuring that the driver has excellent self-damping. This is one of REL's secrets. Understanding that it is the quietness, that attention to bring the driver to complete silence, that produces the most startling dynamics. Whilst Classic 99 will play shatteringly loud, it's from the very black background that the loudest dynamics emerge to produce the sense of shock sought by great composers and directors.
More than Ample Amplification
Classic 99 is big, bold, and full of character, similar to the Stentor II of our youth, but at one-third the price. Of course, the 99 has a great amp. In order to generate deeper bass and significantly higher output, we turned to a tried-and-true Class D amplifier that we've already used in thousands of previous units. This 450 watt amplifier is fed by an all analogue PerfectFilter™ front end that extends useful output well into the low 20 Hz range – superb for a design of this size and price. It produces a sound that's both rich and richly detailed at the same time. Classic 99 borrows the best from current technology to deliver a sound slightly warmer and more like what we all imagine vintage sound to be, with superior reliability and performance than was ever available back in the day.
Classic RELs: What's The Difference
How does the Classic 99 stack up against the hot little Classic 98?
While they look similar, the newer Classic 99 is some 50 percent larger (by volume) delivering 450 watts of power (300w for CL98) into a 12″ driver (10″ for CL98). Those are significant upgrades in the basic spec of the Classic 99. Yes, the Classic 99 is more powerful, plays louder and goes deeper. It should. We walk you through the untold, less obvious story that makes the Classic 99 truly special even while appreciating the magic that is the original Classic 98.

Video review
Our take on the brand
Our Summary
Product Strengths

- Delivers incredible bass for the money and size
- The KC62 provides powerful, deep, and accurate bass reproduction, especially in the lower frequencies
- Features unique Uni-Core technology to fit two woofers into a small cabinet, reducing unwanted resonances
Product Considerations

- App control does not provide direct access to remotely control the sub's own manual settings, therefore, some adjustments still need to be made on the back
- In a big room, it'll definitely lose some steam
Comparisons (according to reviewers)
- The KC62 extends quite a bit lower than the SVS Micro 3000 and is going to have really good extension, especially at lower volumes
- The KF92 has a max SPL that's double the one offered by the KC62, making it a great option for larger listening rooms or home theaters
- The KC62 has a faster response than the REL T/9x, which enhances the vibrancy of percussions in music or exciting moments in movies
