That places the 855 T in Canton's installation line: built for long cable runs, many speakers on one line, and areas you don't want to cover with a chain of amplifiers.\u003c\/p\u003e\u003ch2\u003eWhy the InCeiling 855 T?\u003c\/h2\u003e\u003cp\u003eBecause it can do both. In 100-volt operation you hang an entire zone off a single pair of cables and choose the power tap per speaker – 100, 50 or 25 watts – saving copper, channels and nerves. In 8-ohm operation the same speaker plays as a classic hi-fi ceiling speaker. On top of that come the strongest specs in the series: 135 mm ceramic cone, 91 dB sensitivity, 160 W music power handling.\u003c\/p\u003e\u003ch2\u003eWhat you hear\u003c\/h2\u003e\u003cp\u003ePlenty of level from little amplifier power. 91 dB is a serious figure for a ceiling speaker – the 855 T fills large areas evenly without the electronics breaking a sweat. The ceramic cones sound dry and clean throughout, from 42 Hz up to 40 kHz, and the angle-adjustable tweeter can be aimed at the main zone.\u003c\/p\u003e\u003ch3\u003eWho is the InCeiling 855 T suited for?\u003c\/h3\u003e\u003cp\u003eFor permanent installations: large living areas, practices, shops, hospitality venues, multiroom zones with many speakers. \u003cstrong\u003eStraight talk:\u003c\/strong\u003e if you're looking for two ceiling speakers for the living room and will never run a 100-volt line, you'll be carrying the transformer around without ever using it – the plain 8-ohm models are the better fit then. And with a 270 mm cutout it genuinely needs space in the ceiling.\u003c\/p\u003e\u003ch2\u003eOur verdict\u003c\/h2\u003e\u003cp\u003eThe workhorse among Canton's ceiling speakers: level-stable, efficient, flexibly wired – built for areas, not for the sweet spot. If your project calls for many speakers on few lines, the 855 T is exactly the right tool. And yes, we'll plan the quantity for you instead of guessing.\u003c\/p\u003e\u003ch2\u003eTechnical data\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eType: ceiling speaker, round, 2-way coaxial (free air, passive) with 100V transformer\u003c\/li\u003e\n\u003cli\u003eOperating mode: switchable between 100 V (transformer) and 8 Ω\u003c\/li\u003e\n\u003cli\u003e100V power taps: 100 \/ 50 \/ 25 W selectable\u003c\/li\u003e\n\u003cli\u003eImpedance: 8 Ω (in the 8 Ω setting)\u003c\/li\u003e\n\u003cli\u003eWoofer: 1× 135 mm, ceramic\u003c\/li\u003e\n\u003cli\u003eTweeter: 1× 25 mm, ceramic, angle-adjustable\u003c\/li\u003e\n\u003cli\u003eFrequency range: 42 – 40,000 Hz\u003c\/li\u003e\n\u003cli\u003eCrossover frequency: 3,000 Hz\u003c\/li\u003e\n\u003cli\u003eSensitivity: 91 dB (2.83 V \/ 1 m)\u003c\/li\u003e\n\u003cli\u003ePower handling: 90 W nominal \/ 160 W music\u003c\/li\u003e\n\u003cli\u003eConnection: Easy-Link terminals\u003c\/li\u003e\n\u003cli\u003eOuter diameter (Ø): 290 mm\u003c\/li\u003e\n\u003cli\u003eCutout (Ø): 270 mm\u003c\/li\u003e\n\u003cli\u003eInstallation depth: 90 mm\u003c\/li\u003e\n\u003cli\u003eMax. ceiling thickness: 40 mm\u003c\/li\u003e\n\u003cli\u003eMounting: free-air ceiling install, secured with wing clamps\u003c\/li\u003e\n\u003cli\u003eWeight: 3.2 kg\u003c\/li\u003e\n\u003cli\u003eFront grille: magnetically held, paintable\u003c\/li\u003e\n\u003cli\u003eColour: white\u003c\/li\u003e\n\u003cli\u003eSales unit: piece (single)\u003c\/li\u003e\n\u003cli\u003eScope of delivery: 1 ceiling speaker (piece), magnetic front grille, installation instructions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\u003ch3\u003eWhat does the T stand for in the InCeiling 855 T?\u003c\/h3\u003e\u003cp\u003eThe T stands for the built-in transformer. It lets you run the speaker on a 100-volt installation line, as is common in commercial properties. A selector switch sets the power tap or switches to normal 8-ohm operation.\u003c\/p\u003e\u003ch3\u003eWhich power taps does 100-volt operation offer?\u003c\/h3\u003e\u003cp\u003eOn the speaker you choose between 100, 50 and 25 watts, plus the 8-ohm setting for classic hi-fi use. That lets you distribute the available amplifier power cleanly across all speakers in a zone. We work out which tap goes where as part of your project.\u003c\/p\u003e\u003ch3\u003eCan I run the 855 T on a normal hi-fi amplifier?\u003c\/h3\u003e\u003cp\u003eYes. Switch it to 8-ohm operation and it behaves like any passive ceiling speaker, connecting directly to a stereo or multi-channel amplifier. The transformer then simply goes unused. With 91 dB sensitivity, moderate power is already enough for solid level.\u003c\/p\u003e\u003ch3\u003eHow big does the ceiling cutout need to be?\u003c\/h3\u003e\u003cp\u003eThe 855 T needs a 270 mm cutout diameter and 90 mm of free installation depth, with 290 mm staying visible. That's noticeably more than the smaller InCeiling models. It's approved for ceilings up to 40 mm thick. Measure your ceiling construction before ordering to check it allows for this.\u003c\/p\u003e\u003ch3\u003eDoes the 855 T need an enclosure or damping?\u003c\/h3\u003e\u003cp\u003eNo, it works as a free-air system in the ceiling cavity. Damping material above the chassis does reduce sound transfer into neighbouring rooms, though, which is often required for practices or offices. Whether a sealed back chamber is needed is something Mauri, our technician, clarifies during an on-site visit.\u003c\/p\u003e\u003ch3\u003eWhy buy the Canton InCeiling 855 T from HD Zürisee?\u003c\/h3\u003e\u003cp\u003eBecause a 100-volt installation needs planning: power distribution, spacing, cable cross-sections, zone layout.
