The Alto Professional TS115A:

Truly, the cornerstones of TRUESONIC speakers are affordability, portability, power and accuracy. The TS115A speakers offer exceptionally clear sound for live sound engineers, DJs and musicians alike. TRUESONIC speakers utilize their high-efficiency driver design, their exquisitely pure signal path, and lightweight (yet durable) polypropylene enclosures to provide as precise output as possible of all the deep lows, crystal-clear highs and silky smooth mid-range frequencies. With the uncolored Alto Professional TRUESONIC Series speakers, what you give is exactly what you get.

The TS115A speakers feature cutting-edge Class D amplification built-in to the cabinet. Both the 1” high frequency and 15” low frequency drivers in the TS115A have been designed to ensure that almost no energy whatsoever goes to waste. That design efficiency effectively translates into more power from the amplifier that works to generate sound rather than heat, giving the TS115A far better performance than many other loudspeakers with similar alleged specifications. Every component of the TS115A was developed to provide accurate, transparent, powerful sound.
