{"product_id":"atlantislabat54sub","title":"Atlantis Lab SUB AT 54 Passive Subwoofer (Each)","description":"\u003cp\u003eThe Atlantis Lab SUB AT 54 is a passive large-volume subwoofer with a 54 cm woofer and 250 litres of cabinet volume that plays from 20 to 200 Hz and needs an external power amplifier.\u003c\/p\u003e\n\u003cp\u003eThe French manufacturer Atlantis Lab, founded in 1998 by Eric Buy, builds it with an Eighteen Sound driver in a cabinet of faux leather and oak. At 75 kilos it is not a subwoofer you just shift around – so choose its spot well, you will be living with it for a long time.\u003c\/p\u003e\n\n\u003ch2\u003eWhy the SUB AT 54?\u003c\/h2\u003e\n\u003cp\u003eA 54 cm woofer in a cabinet with 250 litres of volume is designed for depth and headroom: 98 dB sensitivity, 8 Ω impedance and 5000 W power handling. The manufacturer recommends a power amplifier with 500 W. According to the manufacturer, the cabinet volume can be adapted on request.\u003c\/p\u003e\n\u003cp\u003eBecause it is passive, you choose which power amp drives the bass – and with it, how it sounds.\u003c\/p\u003e\n\n\u003ch2\u003eWhat you hear\u003c\/h2\u003e\n\u003cp\u003eThe manufacturer quotes 20 to 200 Hz. That reaches into the range you feel more than you hear: deep organ notes, synthesizer foundations, film effects with punch. A good subwoofer barely draws attention while playing – you only notice it when it is missing.\u003c\/p\u003e\n\n\u003ch3\u003eWho is the SUB AT 54 for?\u003c\/h3\u003e\n\u003cp\u003eFor large rooms and ambitious systems in which a powerful power amp is already in place or planned and the bass should carry all the way down. Plain talk: the SUB AT 54 is passive. You need a power amp (recommended: 500 W) and a way to separate the bass from the rest of the signal, for example via a preamplifier or a crossover. In a small room the smaller SUB AT 33 is the more sensible choice.\u003c\/p\u003e\n\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eThe deep-bass specialist of the brand: big, heavy, robust and freely combinable with the power amp of your choice.

The SUB AT 54 has no built-in power amplifier and needs an external amplifier; the manufacturer recommends 500 W at 8 Ω. That gives you the freedom to choose the power amp and sound character yourself. We help you with the selection and with integrating it into your system.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow deep does the SUB AT 54 play?\u003c\/strong\u003e\u003cbr\u003eThe manufacturer quotes 20 to 200 Hz. That is very deep and reaches into the range you feel more than you hear. How this translates in your room depends heavily on placement and the room itself – we are happy to advise you.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow big is the SUB AT 54?\u003c\/strong\u003e\u003cbr\u003eThe cabinet volume is 250 litres and the weight 75 kg each.

Send us your room situation and we will clarify the space question before you decide.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the price apply per unit or per pair?\u003c\/strong\u003e\u003cbr\u003eThe price applies per unit. In many rooms one subwoofer is enough; if you want to use two, it is best to get advice on placement and tuning.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy buy the Atlantis Lab SUB AT 54 at HD Zürisee?\u003c\/strong\u003e\u003cbr\u003eBecause a passive subwoofer of this size is only as good as its interplay with the power amp and the room.
