As part of our Leema Acoustics events, we will have on demo a pair of very rare speakers (only 4 pairs in the world)

We are amazed to finally have the Serhan & Swift Brigadier BA-2 Loudspeaker in our demonstration room. 

"The BA-2 loudspeaker is the very pinnacle and expression of our years of technical and subjective know-how. It begins with our innovative 'box within box' constrained layer dampened, birch-ply enclosures, the selection of the finest drivers, the critical crossover design process for driver integration, baffle diffraction and phase coherence".
