Brane X vs Zealot S97

Short answer: the Brane X for the deepest bass, the Zealot S97 for the price. The Brane X has the absolute deepest bass in this category, at the cost of boosted upper bass around 120Hz and rolled-off treble. The S97 is the budget pick, since the notes say there is nothing else at its price with that deep bass and reasonable tuning, but it does not get very loud.

The case for the Brane X: Very deep bass, the absolute deepest from this category. The catch: Boosted upper bass ~120Hz, rolled off treble, so it’s missing detail up top.

What the Zealot S97 gets right: There is nothing else for $48 with that deep of bass and a reasonable tuning. The tradeoff: Doesn’t get very loud compared to other speakers in this class.

Buy the Brane X if sound quality matters more than the price. Buy the Zealot S97 if the price matters more than sound quality.

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.

Zealot S97: $65.86 with coupon YZZL10 Aliexpress eBay

Pros: For a compact 3.3kg boombox, the S97 delivers unusually deep, clean-enough bass with a more sensible default balance than many inexpensive Zealot models. It also brings IPX6 protection, aux and microSD playback, power-bank outputs, three EQ presets and PartyAdd linking.

Cons: It is not especially loud for its size, battery life is only a claimed 12 hours, and the bass preset can swamp the rest of the music. There is no app or fine-grained EQ, so the Vocal preset is the only practical way to improve the balance. It is still heavy for a speaker with this output ceiling.
