Sound Tuning or Voicing -- It’s All about Sound Quality 

Most Portable loudspeakers today are “clones”. Cheap plastic knock-offs that share the 
same generic design and are re-badged, re-shelled from a common contract manufacturer. 
So as long as it looks good, nobody cares.   

 
Tuning:  From the Sonic Soul of our In House reference systems  

 
Built as a research project, our in-house reference systems are benchmarked to some of 
the most exotic playback systems. With a key goal of attaining accuracy with musicality, 
the system is continuously tuned and tweaked for best objective accuracy and subjective 
“musical” results.  
Our high performance Gigaworks T3 and the latest Signature series T4 Wireless lineup 
shares similar intrinsic tonal characteristics with striking accuracy AND musicality. 
 
Though the SR20A is a portable wireless system, the in-house system serves to provide a 
guiding “voice”.  Smooth tonal balance with detailed vocals, tight rhythmic midbass and 
full spectral bass  
 
There were multiple iterations before we could get the right tuning for the SR20A.  
 
Catch every word in any music with full warm midrange and detailed tight bass.
