Ruark RS1 Subwoofer

100W Active Subwoofer with Passive Radiator, Designed for Music

The Ruark RS1 is a 100W active subwoofer combining a 170mm long-throw active driver with a matching 170mm passive radiator, delivering extended bass down to 25Hz from a compact, hand-crafted cabinet small enough to sit alongside your speakers — not hidden behind the sofa. Designed as the perfect partner for the Ruark MR1 Mk3, R3S, R410, R610, and R810 (and any other system with a mono RCA subwoofer output), the RS1 is the music sub for people who refuse to put an ugly black cube in their living room.

Why the Ruark RS1 isn't your average subwoofer

Most subwoofers are designed to be hidden. Most are also designed to shake the floor during action films, with everything else as an afterthought. The RS1 is the opposite of both. Ruark built it because MR1 owners kept asking the same question — "the sound is exceptional, but can you go deeper?" — and because the company saw a gap in the market for a subwoofer with actual design intent.

The RS1 is a music-first subwoofer. It's not trying to rattle the windows during the climax of an action film. It's trying to give the low string on a cello real weight, the kick drum in a jazz trio proper presence, the bass line in a pop track the groove it was mixed with. The custom 170mm long-throw driver, the matching 170mm passive radiator, and the 100W Class D amplifier are all tuned to be fast, articulate, and musical — the qualities that matter when you're listening to music rather than dodging exploding helicopters.

It's also one of the few subwoofers on the market that looks like a piece of furniture rather than an embarrassment. Hand-crafted wood top and bottom panels, a slate grey acoustic cloth grille that wraps the cabinet, and proportions designed to match the rest of Ruark's lineup — so you can place it beside your speakers and have it look like it's meant to be there.

What you get

• 100W Class D amplifier with soft-clip protection — clean, controlled output with headroom to spare, and graceful behaviour even when pushed hard.
• 170mm treated fibre long-throw active driver with the control and speed needed for genuinely musical bass.
• 170mm matching passive radiator instead of a tuned port — no port noise, no chuffing, no compromise at higher volumes.
• Extended low-end from 25Hz–200Hz, so you get genuine sub-bass extension rather than just upper-bass reinforcement.
• Adjustable crossover from 50Hz to 180Hz — dial it in to match any speaker, from tiny desktop monitors to large standmounters.
• Adjustable level control for balancing the sub with your speakers and your room.
• 180° phase switch so the sub stays in sync with your main speakers regardless of where you place it (essential if it ends up behind your listening position).
• Auto-on / standby — wakes when it detects a signal, sleeps after 15 minutes of silence. No power management required.
• Mono RCA input with a 1.5m RCA cable included — plug-and-play setup with any system that has a subwoofer or pre-out.
• Hand-crafted cabinet with wood top and bottom panels, wrapped in a slate grey acoustic fabric grille.

Sound: deep, controlled, and properly musical

Ruark's brief for the RS1 was specific: not thunderous, not overblown — deep, controlled, and musical. The passive radiator design (instead of a ported enclosure) is doing a lot of the work here. By replacing the bass port with a tuned mass-loaded radiator, the RS1 delivers extension down to 25Hz without the chuffing, port noise, or one-note bloom that plague cheaper subs at higher volumes.

The 100W Class D amplifier keeps the driver under firm control across the whole frequency range — bass is fast, tight, and rhythmic rather than slow and lumbering. Soft-clip overload protection means it stays composed even when pushed, gracefully limiting rather than clipping audibly.

Paired with a small or compact speaker (especially the MR1 Mk3 desktop speakers, the R3S compact system, or the R410 all-in-one), the RS1 transforms the system into something that punches well above its physical size. Vocals get a richer foundation. Drums get real impact. Bass lines stop disappearing on small drivers and become part of the music again.

Design: a subwoofer you can leave on display

The RS1 follows the same design language as the rest of the Ruark catalogue. Compact proportions (about the size of a small bedside cabinet), hand-crafted wood top and bottom panels, and an acoustic fabric grille that wraps the cabinet rather than just covering the front baffle. The result is something that genuinely looks at home next to a sideboard, a sofa, or a pair of MR1 Mk3 desktop speakers — not something you need to hide.

Two finishes designed to match the rest of the Ruark line:

• Rich Walnut veneer with slate grey fabric grille
• Satin Charcoal lacquer with slate grey fabric grille

At 300 × 250 × 265mm (H × W × D) and roughly 6.7kg, the RS1 is small enough to slot beside a sideboard, under a desk, or next to a bookshelf — and finished to a standard that makes the placement feel intentional rather than apologetic.

• Music-first listeners who want articulate, fast, tuneful bass rather than home-cinema thump.
• Design-led households where a black cube subwoofer simply won't do.

Frequently Asked Questions

Is the Ruark RS1 a music subwoofer or a home theatre subwoofer? A music subwoofer. Ruark designed the RS1 specifically for stereo music systems — fast, tuneful, articulate bass that integrates with your speakers rather than overpowering them. At 100W with a 170mm driver, it's not designed for floor-shaking action-film duty; for that, you'd want a larger dedicated home-cinema sub.

Will the Ruark RS1 work with my non-Ruark system? Yes — the RS1 works with any system that has a mono RCA subwoofer output or pre-out. That includes most stereo amplifiers, AV receivers, active speakers with a sub output, and powered speaker systems. Just plug in the included 1.5m RCA cable.

Does the RS1 work with the Ruark MR1 Mk3? Yes — the MR1 Mk3 has a dedicated mono RCA subwoofer output specifically designed for the RS1. This is arguably the pairing the RS1 was designed for; together they form a properly grown-up 2.1 desktop system.

Which Ruark products is the RS1 compatible with? The RS1 connects to any Ruark product with a subwoofer output, including the MR1 Mk3, R3S, R410, R610, and R810.

Why does the RS1 use a passive radiator instead of a bass port? A passive radiator gives you the bass extension of a ported design without the port noise, chuffing, or one-note bloom that ports can introduce at higher volumes. The result is cleaner, faster, more musical bass — exactly what Ruark was after for the RS1.

How loud / how deep will the RS1 play? The RS1 extends down to a quoted 25Hz — properly sub-bass territory. At 100W into a 170mm driver, it's plenty for normal-sized rooms and music listening, but it's not built to compete with much larger dedicated home-theatre subs on raw output. For music in a small to medium-sized room, it's superbly judged.

How do I set up the RS1 with my speakers? Three controls: crossover, level, and phase. Start with the crossover around 80–100Hz (lower for bigger speakers, higher for smaller ones), set the level so the sub blends invisibly rather than thumping, and try both phase settings — pick whichever gives you fuller, more present bass. Adjust by ear with familiar music.

Where should I place the RS1? Bass is largely non-directional, so you have flexibility — beside your speakers, against a wall, in a corner, or even behind your listening position (use the 180° phase switch if behind). Corners increase output but can muddy the sound; mid-wall placement is often a good compromise. Experimentation pays off.

Does the RS1 turn itself off? Yes — auto-on/standby activates the sub when it detects a signal and puts it to sleep after about 15 minutes of silence, so you don't have to manage the power manually.

Can I use two RS1 subwoofers for stereo bass? The RS1 has a single mono RCA input, so you'd need a system or splitter that can feed both subs from a mono sub output. Most setups won't benefit meaningfully from stereo subs at this price point — a single well-placed RS1 typically delivers cleaner, more even in-room bass.

What finishes does the RS1 come in? Rich Walnut veneer with slate grey fabric grille, or Satin Charcoal lacquer with slate grey fabric grille — both designed to match the rest of the Ruark line.
