London 12

Great sound starts with a great sounding space, but not all rooms are acoustically desirable in their natural state. As a matter of fact, it’s rare for an untreated room to be free of annoying room anomalies such as reflections, flutter echo, standing waves and resonances.

Whether it’s a recording studio, home theatre, boardroom, or any other medium-sized space, a London 12 Room Kit is the perfect solution for controlling sound in rooms up to 150ft², when and where you need it. The panels are available in Black or Grey fabric, or can be painted to match your room.

The London 12 Room Kit contains select Broadway high-quality glass wool panels that tackle problems affecting any room, such as primary reflections, flutter echo, and standing waves. Each kit comes complete with mounting hardware for quick and easy installation.

Yes. Broadway London Room Kits have been tested multiple times to meet class-A requirements in both the United States and in Canada to ensure they are safe for use everywhere. This includes separate tests for the USA called ASTM-E84 and Can/UL C102 for Canada.
Yes they often do. By having one end of the room more ambient and the other darker, you can enjoy different sounds and apply them to instruments to create different effects. For instance a drum kit in a big live room can be made to sound huge! An acoustic guitar with lots of ambiance is particularly cool with classical music. For jazz, you may want to tighten up the drum kit by placing it in a more heavily treated area… it really depends on the production you are trying to achieve.
It is more a question of reflective angles and aesthetics. Most folks space the panels by about 2″ or 3″ apart at the ‘source-end’ of the room while more space is typical at the ‘receive-end’ to allow more air due to reflections.
