Dispersive. Compact. Effective. At last, a dipolar surround speaker at an affordable price – the Alpha S. While many budget-minded speaker systems force tiny, direct-radiating speakers on consumers, the design team at PSB worked tirelessly to develop and offer a cost-minded surround speaker, so that our customers could enjoy the full benefits of high performance home theater. The Alpha S uses the same basic design as Surround found in our higher-end series and creates a more pleasing listening environment by making smaller rooms seem larger through their controlled and incredibly wide dispersion. The Alpha S comes readily wall-mountable, for easy installation in any application.
