Second Best.
That's what the boys in our backroom would have us call this great new Ultralinear ST525.
Just because we assigned them to develop a slightly stepped-down version of our most powerful loudspeaker system, the ST550. To produce a lower-cost Synchronic Time Array, so more of you could experience Ultralinear's breakthrough in sound reproduction.
Dramatic ST550 engineering repositioned all three drivers: to make sure sounds from each travel exactly the same distance, to reach the ear at exactly the same time. Add in our extensive crossover redesign, and goodbye, time/phase distortion! These same principles are handed down to our junior Synchronic Time Array ST525 ... even the same tunable high frequency and midrange drivers that big brother boasts.
The new bass driver is our own 10" Solene cone design that's virtually impervious to cone break-up distortion. And you can adjust bass output via the ST525's exclusive electronically tunable, rear-mounted passive radiator. A totally 3-way tunable 3-way system! We may have to call it our "second best" but you don't. And many won't. There's a lot of clear crisp sound, and a bold new look in the ST525.
And being more affordable than our best (not to mention other name brands) makes our value second to none.
