BRAM ACOUSTICS · OPUS I KIT
Opus I Kit. Take part in its construction.
€2,990 · Pair · VAT included
Opus I Kit lets you build a pair of loudspeakers yourself using the elements of the original design. You will receive the machined enclosures, Beyma drivers, pre-assembled and tested crossovers, and the parts required for assembly.
With Opus I Kit, the experience begins with construction: discovering each part, understanding its purpose and taking part in bringing the design to life.
As you build your Opus I, you will come to know every layer, every joint and every element that makes up the acoustic system. We designed the enclosure so that you can open it again whenever you need to, reach its components and reassemble it. Building it is also a way of understanding the loudspeaker you will listen to for years.

Three-year guarantee on components.
All components supplied by BRAM come with the three-year statutory conformity guarantee applicable to new products sold to consumers in Spain. This includes enclosure parts, drivers, crossovers and fixings.
With the Kit, final assembly is carried out by the buyer. The guarantee covers the conformity of the supplied components, but does not cover damage caused by assembly errors or improper use of tools where BRAM is not responsible.
If incorrect assembly results from deficiencies in the instructions supplied by BRAM, the corresponding statutory liability will apply.
