Focal’s Theva range, side by side. Here is the Theva N°3, the flagship of the range, alongside the N°2 floorstander and the N°1 standmount below it, showing what your money buys at each step.

The Theva N°3 is the flagship of Focal’s Theva range and the largest speaker in it: a three-way floorstander built around 16.5cm drivers, where the N°2 uses 13cm units. It carries the same core technology as its smaller siblings. The TNF inverted-dome tweeter is made in Focal’s French workshops, and the midrange and bass drivers use Slatefiber cones. What the step up buys is cone area. Three 16.5cm drivers move more air than the N°2’s three 13cm units, which brings deeper bass, higher sensitivity and more headroom for larger rooms and higher volumes. It is not a speaker that will fit discreetly into a small room, and it asks for a capable amplifier. What it offers is proper floorstander scale at the top of Focal’s entry-level range.

Brief product overview

The N°3 is a three-way bass-reflex floorstander with a 25mm aluminium/magnesium inverted-dome TNF tweeter, a 16.5cm Slatefiber midrange and two 16.5cm Slatefiber bass drivers, crossing over at 270Hz and 2.7kHz. The tweeter sits in a waveguide to control its dispersion. It hangs from a Poron memory-foam surround derived from Focal’s beryllium tweeter, which reduces distortion in the 2kHz to 3kHz region where the ear is most sensitive. Slatefiber is a cone material made from recycled non-woven carbon fibre in a thermoplastic binder, chosen for stiffness and damping.

Frequency response is quoted at 48Hz to 28kHz (±3dB), reaching 39Hz at −6dB, the deepest bass in the Theva range. Sensitivity is 91dB with an 8-ohm nominal impedance, but the minimum falls to 2.9 ohms in the upper bass, and Focal recommends 40 to 250 watts. The cabinet is ported at the rear and sits on an angled stand that tilts it back so the output of all three drivers arrives at the listener together, which Focal calls Time Alignment. It measures 989 × 212 × 388mm and weighs 20kg, with magnetic grilles. Finishes are Black, Dark Wood and Light Wood.

How it sounds

The N°3 keeps the Focal character, with a clear, detailed treble and an articulate midrange, and adds the weight and scale the smaller Thevas cannot quite reach. The larger bass drivers give kick drums and bass lines genuine body. Because the midrange has its own 16.5cm driver from 270Hz upwards, voices stay clean and full even at high volume. It plays loud without strain in a medium to large room, and the angled stand helps the stereo image lock in at the listening seat. The limits are honest ones. The metal-dome tweeter is revealing, so bright recordings and hard-sounding electronics are shown for what they are. The rear port and generous bass output make placement matter more than with the N°2. And the 2.9-ohm minimum means the speaker needs an amplifier with real current: underpowered, it sounds thin and hard when pushed; well driven, it sounds relaxed and authoritative.

What we’d partner it with

The Onkyo Muse Y-50 makes the N°3 a complete system in a compact chassis. It is a fully digital streaming integrated with an Axign Class D output stage using MOSFET devices, giving 125 watts into 8 ohms and 250 watts into 4 ohms. That doubling of power into the lower load is what the N°3’s impedance dip calls for. Streaming covers Spotify, Tidal and Qobuz Connect, AirPlay 2 and Google Cast. Connections include three line inputs, a coaxial digital input, HDMI with ARC for a television, an MM/MC phono stage and a subwoofer output. A 5.46-inch colour display shows artwork and VU meters. Onkyo Room EQ, run through the app, is useful with a rear-ported floorstander, as it tames the bass peaks rooms add. Two on-list alternatives, stock permitting: the Onkyo Icon A-50 takes a Class AB approach, with 110 watts into 8 ohms, Dirac Live room correction and an MM/MC phono stage; the Arcam SA45 is a step up, with 180 watts into 8 ohms, separate MM and MC inputs and full-band Dirac Live.

For vinyl, the Technics SL-1500C is a strong match. It is a coreless direct-drive deck with a two-layer die-cast aluminium platter, a universal S-shaped tonearm and an Ortofon 2M Red moving-magnet cartridge, plus a built-in MM phono stage on its own isolated supply. With a phono stage in both the turntable and the amplifier, you can choose which one to use; both are worth trying. Alternatives, stock permitting, are the Technics SL-1500CS, the updated version with Technics’ ΔΣ-Drive motor control, and the Pro-Ject The Classic Evo, whose Quintet Red moving-coil cartridge makes use of the Y-50’s MC setting.

The N°3 reaches 39Hz at −6dB on its own, so a subwoofer is optional. If you want one, the Y-50’s subwoofer output makes adding one simple. On cabling, use a well-made speaker cable of appropriate gauge for the run; AudioQuest and Chord are the cable brands we stock.

Who shouldn’t buy it

If your room is small to medium, the Theva N°2 gives the same technology in a slimmer cabinet with bass better suited to the space. If you are building a Dolby Atmos home cinema, the Theva N°3-D adds an up-firing driver in the top of the cabinet, though it needs an AV receiver rather than a stereo amplifier. And if you run a valve amplifier, the 2.9-ohm minimum impedance makes the N°3 a poor partner; it wants a solid-state amplifier with current in reserve.

Fit the N°3 to its angled stand before positioning it, as the stand sets the backward tilt that aligns the three drivers at the listening seat. The port is on the rear and the N°3 produces plenty of bass, so give it space: start with around 50 to 70cm between the rear of the cabinet and the wall and adjust from there. Moving it closer fills out the bass, and moving it further away tightens it. Angle the speakers only slightly towards the listening position, as the tweeter is brightest directly on axis. Connect the speaker terminals to the Y-50’s outputs with a cable run of equal length for each side. Once the speakers are in place, run Onkyo Room EQ from the app to smooth the bass interaction between the N°3 and the room. Connect a television to the Y-50’s HDMI ARC input if you want one in the system. For vinyl, the SL-1500C connects to the Y-50’s phono input set to MM, with the deck’s own phono stage switched off, and its earth lead goes to the amplifier’s ground terminal. Alternatively, switch the deck’s phono stage on and connect it to a line input.
