STILETTO 15 is a 3-way reference loudspeaker design that delivers a carefully balanced and highly engaging sound signature. This is accomplished by seamlessly combining the articulate and dynamic bass response of an open baffle woofer with the remarkable clarity and imaging of a sealed-box midrange and tweeter.

Listeners seeking authentic bass, superb midrange and effortless top-end extension will quickly become captivated with Vinnie Rossi’s unique design approach. STILETTO 15 is well-suited for a variety of different room sizes (including smaller ones) and excels with near field and mid field listening distances.
