What We Think

Primacoustic's London room acoustics bundles are an incredible value and an excellent choice for treating the acoustics of your studio. Their Rockwool-based absorption panels are far more effective at absorbing a broad range of frequencies than foam-based acoustics products, yet these London kits are priced very competitively compared to foam.

You may find yourself wanting more of one thing or another with these kits depending on your specific room, but these kits are an excellent place to start if you're looking to improve the sound of your room, and even the small London 8 kit will give you a dramatic improvement - eliminating flutter echoes, tightening up the mids and low end and giving you more definition in what you're recording and hearing.

Manufacturer's Description from Primacoustic

London room kits include a remarkable combination of acoustic panels and hardware that together solve many of the usual problems associated with studio acoustics. To dissipate high frequency flutter echo and reduce standing waves, Scatter Blocks are positioned at the ‘receive’ end of the room. To control powerful reflections in the critical mid range, Control Columns are positioned on side walls and on the ‘source’ wall. To help manage low frequencies and reduce the effect of room modes, two large broadband absorbers (London Bass Traps) are positioned in the corners (London 12 and 16 only). For the London 8 and 10 you can add the London Bass Trap™ kit if desired.
All panels are made from high density 6lb glass wool and fully encapsulated with micromesh. Edges are resin treated to produce sharp-looking architecturally attractive lines. Panels are then covered with acoustic fabric in a choice of three neutral colors to match most room decors. London kits come complete with Surface Impalers to mount panels flush to walls, Corner Impalers to create the bass traps in room corners and all of the screws and wall anchors you need to do the installation. We even include the drill bit!
Class-1 fire rated for safe installations anywhere. No glue needed. Installation is clean and easy. Available fabric colors: black, beige and grey.

The London 8 contains select Broadway panels that tackle problems affecting any room, such as primary reflections, flutter echo, and standing waves. In addition to acoustic panels, each London 8 room kit includes the corresponding mounting hardware and instructions for easy installation.

Broadway panels are made from high-density 6lb per cubic foot fiberglass, offering nearly five times greater absorption than typical low cost foam alternatives. This means that you get more absorption with less panels, while assuring an even absorption curve throughout the frequency range. The London 8 room kit is available in three fabric colors. 12 panels included.

About Manufacturer

If you are listening to the sound system in a church, PA system at an airport, or a concert in a hockey arena and are not impressed, it is probably not the fault of the PA system, but more likely the lack of proper acoustical treatment in the room.

Architects have just begun to understand that a great looking room that may be ‘functional for people’, may in fact introduce horrendous results when it comes to acoustics. This can be partially attributed to the lack of inter-disciplinary cross-training at universities and from a historical perspective, the science of acoustics has been kept a ‘dark secret’ that could only be conjured by mythical creatures called acousticians.

But this is changing. Through trial and error, advanced computer modeling and greater understanding of acoustical behavior, we can now predict with relative certainty how sound will behave in a given room. And as more and more folks have come in contact with acoustics, there is an appreciation for the benefits which, only a decade ago, were simply invisible. In fact awareness regarding the importance of acoustic sound control has gained such prominence that many top notch sound contractors will refuse to switch out the PA system in a church unless problems with the acoustics have been resolved for fear that the new PA will not yield any improvement and will only serve to tarnish their reputation.

Radial Engineering Ltd. pioneered the benefits of acoustics nearly 20 years ago by importing a brand of acoustic panels from Europe and supplying them to our customers. We quickly became frustrated as the product was expensive and it seemed that the company’s focus was heading towards industrial noise control—not music. We wanted a solution for studios, churches, broadcast and other music related venues. Primacoustic was created in Year-2000 as a means to provide simple solutions. Little did we know that within 10 years the market would completely shift, that most professional recording would move from the studio to the home and that schools and churches would begin to realize that the majority of their room problems were in fact caused by poor acoustics, not the audio system.

Today, Primacoustic has become a market leader in high performance acoustic products. Our ground-breaking Broadway acoustic panels not only grace the studio walls of international artists such as Tommy Lee, Nathan East, Scott Henderson, and David Bottrill, they have also been selected at gaming giants Electronic Arts and Transformers and were used to control the acoustics at the Vancouver 2010 Winter Olympics by US giant NBC and Canada’s CTV in the International Broadcast Center.

Primacoustic begins with the premise of a no-compromise approach on acoustical performance. In fact, Broadway panels are as good, if not better, than the most expensive panels made today. The ‘win’ is achieved by following the ‘Model T Ford approach’ of mass producing a limited selection as a means of lowering costs.

Primacoustic offers a wide array of acoustic solutions that spans all market segments. This includes special T-bar ceiling tiles that help retain sound inside a boardroom, acoustic clouds for call centers and studios and bass traps & diffusers for high end control rooms. Each product is engineered to deliver maximum performance while presenting the very best value.
