INTRODUCTION

StageFront Home Theater Solutions loudspeakers are expressly designed
for superior sonic quality in home theater applications. Each model employs
advanced technology components that extract the subtle nuances in recorded
music or the thunderous action sound in a movie. Models ending in “LCR” are
intended primarily for front channel left/center/right placement or wherever a
monopole design is required. Models that end in “FX” are designed for special
effect placement. StageFront models are the perfect choice wherever quality of
sound is the most important consideration.
