The screen

The first question you should ask yourself: projector or television? Many factors can influence this decision: the size of the room, picture quality, and your budget. For a more affordable home theatre, a wall-mounted 50 inch (minimum) flat-screen TV can do the trick. If you’re looking for something a little closer to the multiplex experience, you’ll want to go with a projector.

You can choose to have it fixed, retractable, motorized … even 3D! Some rules to keep in mind: the screen must keep a 16:9 ratio and be at a distance of twice the diagonal length of the screen from the viewers.

Soundproofing

If you’d like to maintain a good relationship with your neighbourhood (or just avoid annoying your whole family), you should consider soundproofing your home theatre! It’s a must to not only prevent sound bleed, but also maintain impeccable acoustics in your new room. The golden rule is to have at least 40% of your surfaces absorb sound.  

Start with air leaks: they will necessarily lead to sound leaks, which is what you’re looking to avoid at all costs. The room must be completely hermetic. First, make sure your walls are sealed: stuff them with acoustic insulation wool and make sure you have at least two layers of gypsum to avoid low frequencies bleeding through. You can then move on to the doors and jambs. We recommend a steel door, but you can always go for an acoustic sealant if your budget is smaller. Finally, don’t forget about the electricity! Isolate your electrical outlets and invest in noise-reduced bulbs for optimal acoustics.

The sound environment

A basic home theatre is usually made up of five speakers: one central, two lateral speakers placed on each side of the screen, as well as two others located at the back of the room.

You can find basic sets with speakers, an amplifier, a receiver and all the wiring for under $1000. If you’d like to invest in higher-end equipment, buy the items separately. You can also invest in more speakers to ensure an all-surrounding state-of-the-art sound. When you’re drawing up your budget, don’t forget to include wiring: it can represent 15% to 20% of the costs of electronic equipment.

Regardless of your financial plan, remember that it’s important to be consistent with the quality of your components. An exceptional screen paired with low-end speakers could put a damper on your movie experience. Give your project the means to achieve its ambition.

The seats

Because a good movie should be enjoyed comfortably, you shouldn’t neglect the quality of the seating. Of course, a simple couch can always do the trick. To host more movie lovers in your own private theatre, you should get modular-type furniture. Dreaming big? Build a true projection hall with raised individual cinema-style seating set out in rows. No need to leave the house after that!
