PSB Alpha Intro LR Loudspeakers (pair)


If you're looking for ultracompact, highly detailed speakers for your bedroom or small den, this little ensemble may be a big surprise.


The Alpha LR represents the smallest speaker in PSB offerings and still manages to deliver unwavering performance. As "sub/satellite" speaker packages evolved as a popular choice for home theaters, PSB engineers worked to create an economic and effective solution. 

The Alpha LR can be wall-mounted, placed on stands or fit into most entertainment centers to deliver maximum performance while still remaining aesthetically pleasing. The true 2-way design employs a single 3.5-inch mid-woofer paired with a single .75-inch ferrofluid-cooled tweeter . The result is an extremely tight sound with excellent imaging characteristics.
