From Switzerland, a compact phase corrected active speaker that reflects its pro background. But is it house trained? Although virtually unknown in the UK, PSI can trace its roots back to 1975, when founder Alain Roux first started manufacturing his own loudspeaker designs while still studying at the Lausanne École Polytechnique Fédérale. Over the past 35 years, this Swiss company has produced a range of custom, domestic, but mostly professional studio loudspeaker systems. In 1991 an analogue and digital electronics section was added to the acoustic laboratory at its Yverden manufacturing facility.
