Primacoustic London 12 Overview

The London 12 Room Kit from Primacoustic has been designed to address acoustic room problems such as primary reflections, flutter echo, standing waves, and excessive bass. It is intended for rooms up to 150 ft² (13.9 m²), or can be combined with other products to treat larger spaces. This package is a single-box solution for studio control rooms and home theaters.

Broadway panels are made from high-density, 6 lb per cubic foot glass wool, offering more substantial absorption than foam alternatives. This means that you get more absorption with fewer panels, while assuring an even absorption curve throughout the frequency range.

This London 12 room kit comes in an Absolute White paintable finish and includes 22 panels (two broadband panels, eight control columns, and 12 scatter blocks). The kit includes all the necessary mounting hardware and instructions for easy installation.

A great start

So, this kit has has been a great start to getting my room in order! They look great, were easy to install and are effective to tame flutter echo, early reflections and, to a similar extent, some reverb issues. The kit comes with 2 bass-trap panels, which I think could be more effective at 4" depth but this is easily remedied. Also, always remember, kids... try to get the low-end response at the listening position in your room balanced as best you can before adding other treatments. This kit does exactly what I need it to do and I'd purchase again in a heartbeat.
