These are not really the same size class, and that is the honest framing here. The Brane X ranks #4 of 78 large speakers by sound quality at $500; the Denon Home 250 ranks #11 of 17 powered desktop speakers by sound quality at $549.
The case for the Brane X: The Brane X pairs a dedicated RAD subwoofer with two midrange drivers and two tweeters to achieve extraordinary low bass for a 3.5kg portable: its measured -10dB extension is 31Hz. The tradeoff: The front-facing design has only moderate dispersion, so sound changes noticeably off to the sides or behind it.
The case for the Denon Home 250: Two outward-angled tweeters plus two mid-bass drivers and a rear passive radiator give it true stereo separation from a single cabinet, each driven by its own Class D amp for a claimed combined 80 watts. The tradeoff: Trusted Reviews’ own complaints are a slightly disjointed hand-over between the bass and midrange, and a safety-first treble response that avoids sounding harsh at the cost of outright detail.
Buy the Brane X at $500 if you want a large speaker. Buy the Denon Home 250 at $549 if you want a powered desktop speaker instead.
Water resistance is not close: the Brane X is rated at IP57 (brief submersion), well ahead of the Denon Home 250 at no water resistance.

The Two Speakers In Full
Brane X: $500 Amazon eBay
Pros: The Brane X pairs a dedicated RAD subwoofer with two midrange drivers and two tweeters to achieve extraordinary low bass for a 3.5kg portable: its measured -10dB extension is 31Hz. Independent testing finds it loud, with well-balanced mids, a smooth treble balance and useful bass-level controls; Wi-Fi, AirPlay, Alexa, quality Bluetooth codecs and low-latency aux pass-through make it unusually versatile. Measured bass extension of 31Hz (-10dB).
Cons: The front-facing design has only moderate dispersion, so sound changes noticeably off to the sides or behind it. Bass response shifts at maximum volume, the default aux mode has very high latency, and some listeners find the upper register edgy or need EQ to achieve their preferred balance. Its claimed 12-hour runtime and premium cost make it more of a compact high-end system than a carefree all-day speaker.

Denon Home 250: $549 each Amazon eBay
Pros: Two outward-angled tweeters plus two mid-bass drivers and a rear passive radiator give it true stereo separation from a single cabinet, each driven by its own Class D amp for a claimed combined 80 watts. Trusted Reviews called the sound confident and wide-ranging, with expansive, well-resolved detail and adequate low-end punch and substance. Amazon Alexa is built directly into the speaker via its own microphones, on top of AirPlay 2, Bluetooth and the HEOS multi-room app.
Cons: Trusted Reviews’ own complaints are a slightly disjointed hand-over between the bass and midrange, and a safety-first treble response that avoids sounding harsh at the cost of outright detail. Only network or USB-sourced audio gets full hi-res quality; MQA-powered Tidal Masters streamed through the HEOS app gets stepped down to 16-bit/44.1kHz.
