Stereoindex Picks: Exceptional Speakers for Serious Listening Rooms and Refined Home Cinema

The Dali Kubik One stands out in the source material as a unusually substantial soundbar, weighing almost 10 kg and using an all-aluminum body rather than a lightweight enclosure.

It is presented as a modern one-box speaker solution with removable grilles, front-panel controls, its own remote control, and the ability to learn commands from another remote, such as a TV handset.

A rear low-frequency output adjustment switch helps tailor bass balance depending on placement, although the source sensibly suggests trying all modes and choosing the preferred result.

The Alsyvox Michelangelo is the most extreme loudspeaker in the selection, both physically and technically.

Each speaker system uses three panels in a symmetrical ribbon-based architecture, with flat ribbon low-frequency drivers and a central section containing midrange, high-frequency, and super high-frequency ribbons.

The source describes it as Alsyvox’s flagship model, positioned above related Caravaggio and Raffaello designs, with claimed gains in sensitivity, dynamics, and resolution compared with a double Caravaggio concept.

The Ultimea Skywave F40 is positioned as an accessible home-cinema upgrade rather than a minimalist TV bar.

The package includes a main soundbar, two wireless rear satellite speakers, and a dedicated subwoofer, giving it a fuller surround-oriented layout than a single-bar system.

The rear speakers receive audio wirelessly from the soundbar but still require power, while the subwoofer uses a wired connection, a practical arrangement that can reduce wireless bass reliability concerns where cable routing is simple.

The Albedo Axcentia MKII is a passive three-way floorstanding speaker built around a Linear Phase design, according to the manufacturer.

Its driver complement uses Accuton ceramic units: a 1.2-inch tweeter, a 5-inch midrange, and two 7-inch woofers.

The acoustic design combines a transmission line with a Helmholine resonator, while the first-order crossover is described as supporting frequency and phase linearity. The cabinet is substantial, with a multi-layer body, metal panels, internal spacers, and an 85 kg weight per speaker.

The Noble & Noble Nobilis Sonum 126 is an active speaker system with amplification, DSP, and DAC functions housed inside the cabinet.

The source emphasizes the integrated nature of the design, including dedicated amplification for each speaker and a signal path that remains digital until final conversion for the drive units.

Mechanical and acoustic refinements include a patented Vibration Cancellation System, an Inert Ring intended to reduce cone-tip distortion, tweeter isolation, and a carefully shaped waveguide. Installation accessories are included, and the speakers are described as suitable for wood, marble, and carpeted floors.

This entry is not a loudspeaker, but it is relevant to owners of bi-wireable speakers.

The source explains that AudioQuest BASS cables can be used with speakers that have two sets of connections and can be combined with AudioQuest ZERO cables to create a bi-wire pair.

It also notes that ZERO and BASS can be joined at the amplifier end as a bi-wire COMBO. Because the article is promotion-led, its discount details should be treated as time-sensitive rather than as an evergreen reason to buy.

The Raidho Acoustics launch covered two DSP-powered subwoofers and a new reference-level floorstander.

The TD8 SUB and TD10 SUB use diamond-coated Ceramix active drivers, passive radiators, Hypex Ncore amplification, and PC-controlled DSP.

The TD8 SUB pairs two eight-inch active drivers with two ten-inch passive radiators, while the TD10 SUB scales up with two ten-inch active drivers and four ten-inch passive radiators. The source also notes stackable tower configurations and premium finishes in burr walnut or black lacquer.

The Alexandria Audio Gaius is a mid-size three-way floorstanding speaker and the company’s inaugural model of this type, according to the source.

It uses a bass-reflex design with a 220 mm low-frequency driver, a 170 mm midrange unit, and a 45 mm high-frequency driver.

The source highlights a development process involving measurements, evaluation, tuning, and retesting, with attention to crossover parameters, damping, and sound tuning. Its stated specifications include a 25 Hz to 45 kHz frequency range, 91.5 dB sensitivity, 4 ohm nominal impedance, and 108 dB maximum sound pressure level.

The Stenheim Alumine Two.Five is a Swiss floorstanding loudspeaker with an enclosure made entirely from aluminum.

The two-way design uses two 170 mm cellulose-cone woofers and a 26 mm soft-dome tweeter, with a front-mounted round bass reflex port.

The source highlights high sensitivity, stated at 93 dB, along with a 4 ohm nominal impedance, 125 watt continuous power input, and 250 watt peak input. Each speaker weighs 45 kg and is produced at Stenheim’s factory in the canton of Valais.

The Cabasse Pearl Keshi is a compact 2.1 triphonic system built around the brand’s spherical point-source concept.

It pairs a 22 cm spherical subwoofer with two very small 8 cm satellites using patented Dom55 broadband drivers with ultra-thin cones and neodymium magnets.

The subwoofer uses a proprietary 17 cm Held driver, and the system includes onboard DSP, automatic CRCS room correction using a built-in microphone, multi-room integration through StreamControl, broad file-format playback, and a built-in DAC specified for high-resolution streams up to 32 bit and 768 kHz.
