Ultra SQL – The Conception Of Sound Quality Loud
The esteemed Xcelsus SQL range came to fruition after engineers from the company visited a show and stopped to take a look at some SPL vehicles on display. Taking to the owners they noticed a common theme started to emerge, in that most complained that at high volume that the sound quality was sub-par and aggressive. But given they like to listen to music at high levels, there’s precious little options available in the market. Just imagine if there was a range of components that could play extremely well and at extreme volumes. Hence the ideologies and inspiration began and the Xcelsus Ultra SQL, or Sound Quality Loud; range was born.
