The Truesonic Series was designed from the ground up to be the most transparent loudspeaker money can buy. Rigorous testing and thousands of hours of listening have gone into making sure that what you pump into a Truesonic speaker is exactly what you get out. Everything you see (and some things you don't) - from internal signal path and components used to the sculpted cabinet and meticulously designed waveguide - was developed in service of the principle of accurate, transparent sound. The drivers in the Truesonic TS115 are designed to make sure that virtually no energy is wasted. That translates to more of the power from the amplifier actually working to generate sound rather than heat, giving the speaker better real world performance than other speakers with comparable published specifications. The Truesonic TS115 offers a 15" LF driver (2.5" voice coil) and a 1" HF driver (Neodyminum Driver). Color: Black.
