{"product_id":"atlantislabat21","title":"Atlantis Lab AT21 Bookshelf Speakers (Pair)","description":"\u003cp\u003eThe Atlantis Lab AT21 is a high-performance bookshelf speaker with a compression driver and a 90×90° horn that delivers level and dynamics at 96 dB sensitivity, even with small amplifiers.\u003c\/p\u003e\n\u003cp\u003eIt is built by the French manufacturer Atlantis Lab, founded in 1998 by Eric Buy, with drivers from Eighteen Sound. The AT21 looks like a bookshelf speaker and behaves like a much bigger one.\u003c\/p\u003e\n\n\u003ch2\u003eWhy the AT21?\u003c\/h2\u003e\n\u003cp\u003eThe treble is handled by a 1-inch compression driver in the horn (called a Dolby Atmos horn by the manufacturer), which radiates in a controlled 90×90° pattern. Horns stand for directness and dynamics, and that is exactly the programme here. Below it works a 21 cm paper woofer from Eighteen Sound, complemented by a 13 cm polypropylene driver on the back. Anyone who claims bookshelf speakers have to be modest simply hasn't unpacked an AT21 yet.\u003c\/p\u003e\n\n\u003ch2\u003eWhat you'll hear\u003c\/h2\u003e\n\u003cp\u003eThe data sheet paints a clear picture: 35 Hz to 20 kHz and 96 dB sensitivity. That means reserves, directness and playfulness, even if your amplifier doesn't carry a powerhouse business card. The specialist press particularly highlights immersion and sensitivity.\u003c\/p\u003e\n\n\u003ch3\u003eWho is the AT21 for?\u003c\/h3\u003e\n\u003cp\u003eFor everyone who wants dynamics and presence without a floorstanding cabinet in the living room, for example with tube or lower-powered amplifiers. Plain talk: at 56.5 cm tall and 19 kg per speaker, the AT21 is not a roommate for your bookshelf. It belongs on a solid stand (the manufacturer recommends 45 cm height). And as a passive speaker it needs an amplifier that drives 4 Ω cleanly.\u003c\/p\u003e\n\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eA bookshelf speaker for people who take sensitivity and dynamics seriously, with French character, high-quality drivers and a 7-year manufacturer warranty. It demands space and a good stand, and thanks you with a directness you rarely find in bookshelf speakers.\u003c\/p\u003e\n\n\u003ch3\u003eWhat the press says\u003c\/h3\u003e\n\u003cp\u003eAudio Art (Taiwan) gave the AT21 the “Best Recommended” award and, paraphrased, highlights the immersion and the high sensitivity for small amplifiers.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: Bookshelf speaker (passive)\u003c\/li\u003e\n\u003cli\u003eTweeter: 1″ compression driver with horn (90 × 90°)\u003c\/li\u003e\n\u003cli\u003eWoofers: 21 cm paper (front), Eighteen Sound; 13 cm polypropylene (rear)\u003c\/li\u003e\n\u003cli\u003eFrequency range: 35 Hz – 20 kHz\u003c\/li\u003e\n\u003cli\u003eSensitivity: 96 dB\u003c\/li\u003e\n\u003cli\u003eImpedance: 4 Ω\u003c\/li\u003e\n\u003cli\u003ePower handling: 250 W (peak 500 W)\u003c\/li\u003e\n\u003cli\u003eRecommended amplifier power: 6 – 400 W\u003c\/li\u003e\n\u003cli\u003eBinding posts: pure copper\u003c\/li\u003e\n\u003cli\u003eDimensions (W × H × D): 26 × 56.5 × 36.5 cm\u003c\/li\u003e\n\u003cli\u003eWeight: 19 kg each (pair: 38 kg)\u003c\/li\u003e\n\u003cli\u003eRecommended stand height: 45 cm\u003c\/li\u003e\n\u003cli\u003eWall distance: from approx. 5 cm\u003c\/li\u003e\n\u003cli\u003eBreak-in time: approx. 100 hours\u003c\/li\u003e\n\u003cli\u003eFinish: faux leather black or beige with oak\u003c\/li\u003e\n\u003cli\u003eWarranty: 7 years (manufacturer warranty)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need a big amplifier for the Atlantis Lab AT21?\u003c\/strong\u003e\u003cbr\u003eNo. The AT21 is a passive speaker, the manufacturer quotes 6 to 400 watts, and with 96 dB sensitivity it copes well even with low power. What matters is that the amplifier drives 4 Ω cleanly. We are happy to check with you whether your device fits.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I place the AT21 close to a wall?\u003c\/strong\u003e\u003cbr\u003eYes, the manufacturer quotes a wall distance from about 5 cm, but recommends a stand of around 45 cm height. How much distance makes sense in your room and how best to tune bass and spaciousness, we are happy to clarify in a conversation with you.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich finishes does the AT21 come in?\u003c\/strong\u003e\u003cbr\u003eThe manufacturer lists faux leather in black or beige, combined with oak. Which variant suits your furnishings and your room, we are happy to discuss with you before you order. Just write to us or call.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long is the break-in time?\u003c\/strong\u003e\u003cbr\u003eThe manufacturer recommends around 100 hours of break-in. During this time the sound opens up step by step, because the drivers have to settle in first. So give it time and don't judge the AT21 after the first evening.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the price apply to a pair?\u003c\/strong\u003e\u003cbr\u003eYes, the price applies to a pair, i.e. two speakers for classic stereo. Stands are not included; you will find suitable ones among the speaker stands. We are happy to advise you on height and placement in the stereo triangle.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy buy the Atlantis Lab AT21 from HD Zürisee?\u003c\/strong\u003e\u003cbr\u003eBecause we think of speakers, amplifiers and cabling as a system.
