Capella delivers remarkably precise imaging and a clear, controlled midrange, refined further by its integrated room calibration DSP. The compact active speakers combine tight bass control and a unique horn tweeter with luxurious finishes and extensive streaming I/O, earning praise from Part Time Audiophile for sound, features and value.
Pros
Excellent imaging with precise instrument placement, creating a convincing soundstage.
Integrated DSP room calibration via the app provides measurable correction and simplifies tuning for varied rooms.
Comprehensive connectivity (WiSA, Wi‑Fi, Bluetooth, HDMI/ARC, USB, optical) and high‑quality finishes deliver exceptional system value at the price.
Cons
Bass doesn't extend as deeply as a dedicated full‑range or sub‑equipped system; bookshelf drivers have natural limits.
Stereo Hub lacks a subwoofer output, restricting low‑frequency expansion options for users who want more bass.
Setup quirks: system requires three power outlets and the aluminium remote can be awkward to use in low light.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 90/100
Bass
89/100
16 cm mid-woofer and bass-reflex design with a stated response to 42 Hz (-3 dB) gives noticeably authoritative low end for a bookshelf. Reviewer notes a "definite bass port bump in the 45-75 Hz range" and the DSP/active crossover tightens control, though it "doesn’t go as deep as I would have liked." Overall very strong extension and control for the driver size.
Mid
91/100
Midrange is a clear strength: reviewer compares the tweeter/mid to Triangle's Antal and highlights focus on the tweeter and midrange. The use of a natural cellulose 16 cm driver plus DSP linearisation produces clear, well-bodied vocals and instruments with only a touch of dryness from the Class D amplification.
Treble
90/100
Unique 25 mm horn tweeter with magnesium alloy dome yields refined detail and good extension; reviewer calls the tweeter design uncommon and notes a neutral, less 'sweet' presentation. Treble is detailed without reported harshness, though slightly leaner due to the onboard Class D electronics.
Soundstage Imaging
92/100
Imaging is described as "excellent with very precise instrument placement," and the active DSP/hub calibration supports stable, well-defined images and depth for a near-field to moderate room setup.
Dynamics
88/100
Bi-amplified 2x50 W per speaker and DSP protection yield good macro and micro dynamics with controlled power handling. Reviewer notes Class D amplification is a bit drier compared with higher-end Class AB electronics, so while punch and control are strong, there is slightly less warmth than some traditional systems.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
92/100
High-quality finishes and veneers (multiple colorways) impressed the reviewer—'painted burl walnut veneer... finish is fantastic.' Cabinet fit-and-finish and perceived refinement match the price and expectation of a premium product.
Features Connectivity
94/100
Comprehensive Stereo Hub: USB-B, SPDIF (optical/coax), RCA, 3.5mm, HDMI/ARC, Wi‑Fi, WiSA, Bluetooth, Chromecast, AirPlay, UPnP/DLNA and Roon Ready; plus onboard DSP and room calibration with before/after curves. The only noted omission is a subwoofer output, which the reviewer called a potential game changer.
Value for Money
94/100
At $2,999 the reviewer calls the Capella 'basically everything you need but a turntable' and a bargain, saying you'd be hard-pressed to match its sonics for the price. Strong feature set plus finish and sound make it an easy recommendation versus building an equivalent traditional system.
