Every third luxury listing seems to have a sala de cine. Sometimes it is a blacked-out room with a projector and seven speakers. Sometimes it is a television on the basement wall. The difference is measured in metres, lumens and decibels, and it belongs in the contract.
The first is a dedicated room: no window or a window that blacks out, dark walls, a fixed screen, speakers around the seats. The second is a media room, usually a basement with a large television and a sofa. The third is a projector in the living room, which works at night and disappoints at noon. The fourth is an empty room the agent calls posibilidad de sala de cine, and that is not a cinema at all.
Ask for photographs with the lights on as well as off. A dark photo hides a low ceiling, a pillar, a boiler or a damp patch. Ask for the projector model, the screen size and the amplifier. If the answer is home cinema completo and nothing else, assume the equipment is old and the room is a basement with a sofa.
Screens are sold by diagonal, but the projection is calculated from width. A 16:9 screen of 100 inches is about 221 by 124 centimetres. At 120 inches it is 266 by 149, and at 150 inches 332 by 187. A 150 inch screen needs a wall of at least 3.4 metres and a room deep enough to sit four metres back without your neck complaining.
Throw distance is the distance from the lens to the screen, and it equals the throw ratio multiplied by the screen width. A 1.2:1 projector needs 3.2 metres for a 120 inch screen. A 1.5:1 needs four metres. A short-throw 0.4:1 needs about 1.1 metres, which is why short-throw units are popular in small Barcelona basements. Measure the room before you believe the maximum image size in the brochure.
A projector needs about 1,000 ANSI lumens for a 100 inch screen in a dark room. Two thousand is a safer figure if the room has any light or the screen is larger. HDR asks for more. White walls and a glossy floor bounce light back onto the screen and turn black into grey. Blackout blinds, a dark ceiling and a dark wall behind the screen do more for the image than another 500 lumens.
Lamp projectors run 3,000 to 6,000 hours on a lamp, and a replacement is €150–400. Laser units are rated around 20,000 hours and cost more upfront. Ask to see the hours counter in the menu. A projector with 4,000 hours on a 5,000 hour lamp is a bill waiting for you, not a feature.
A 5.1 system puts five speakers around the seats and a subwoofer on the floor. Atmos adds height channels in the ceiling, which is lovely in a dedicated room and pointless in a basement with a 2.3 metre ceiling. Hard stone floors, glass tables and bare walls create echo. A rug, curtains and four acoustic panels cost less than a new amplifier and fix more.
Bass is the part that travels. It goes through the floor slab, the party wall and the garage ceiling, and in an adosado it arrives in the neighbour's bedroom before it arrives in your kitchen. Keep the subwoofer off a floating timber floor, use a isolation pad and agree reasonable hours. The lease can say 22:00 to 09:00 for cinema use. Whether the neighbour respects it is another matter, but the clause gives you something to point at.
A projector pulls 300 to 600 watts. An AV receiver another 300 to 600. Add a games console, a media server and the air conditioning, and a small room becomes a heat box by the second film. A 5.75 kilowatt supply is fine for the cinema alone, but not if the pool pump, the oven and the air conditioning are running at the same time. Ask which circuit the room is on.
Ventilation matters as much as cooling. A sealed basement with eight people in it smells of carpet and warm electronics by the interval. Check for a vent, a return grille or at least a door that can stay open. Dust kills projector filters and filters kill lamps. If the room sits under the garage, look at the ceiling for damp before you fall in love with the screen.
A serious projector runs €1,000–6,000. The screen adds €300–2,000, the audio €1,000–5,000, the seats €1,000–4,000 and acoustic treatment €1,000–5,000. Installation, cabling and calibration are another €500–2,000. A landlord who spent €15,000 on the room will list the equipment in the inventory. A landlord who spent €800 on a projector and a white wall will call it a cinema anyway.
If you install your own projector, the ceiling mount is a fixed element. Article 23 of the LAU requires written consent for anything drilled into the wall or ceiling, and the lease should say whether the mount stays or goes. In-wall and in-ceiling speakers are worse: they leave holes. A freestanding screen and a shelf-mounted projector leave with you and are the safer choice on a one-year contract.
Who services the projector and how often, who pays for a lamp, who recalibrates after a move, what happens if the screen is damaged, and whether the equipment is covered by the owner's insurance or yours. Contents policies often put a sublimit on home cinema and audio gear, and a projector stolen from a basement is not always covered by the building policy.
If the projector dies in week two, report it in writing and ask for a repair date. Do not stop paying rent. The equipment is part of what you rented, so a long failure can justify a rent reduction, but only by agreement or through the legal route. A WhatsApp message and a dated photo are the beginning of that conversation, not the end.
A good cinema room is a pleasure and a reason to stay in on a Tuesday. A bad one is a dark basement with an old projector and a bill for a lamp. The room tells you which one it is in ten minutes, if you visit with a tape measure and turn the lights on.
