Punching well above their class with breathtaking clarity, detail, and dynamics, the Prime Bookshelf speaker fills a room with pristine sound and impactful bass. Perfect for stereo listening, as surrounds, or as any speaker in a home theater surround sound system. Standing out among the crowd of bookshelf speakers is no easy task, yet the Prime Bookshelf defies convention to outperform reference monitors costing twice as much or more. Every aspect of the Prime Bookshelf speaker was designed for sonic excellence. From the premium grade driver and sophisticated SoundMatch crossover to the extra-thick baffle, internal bracing, and FEA optimized tweeter diffuser, the Prime Bookshelf speaker's design and engineering credentials put it in the realm of much costlier, and much larger speakers. The Prime Bookshelf speakers are sonic overachievers on all levels. Stunningly dynamic, pinpoint accurate and utterly transparent, they deftly serve as reference monitor loudspeakers in a two-channel system, or as high performance front, center, or side/rear surround speakers in a multi-channel home theater. Borrowing engineering and design cues from the acclaimed Ultra Series and embodying all the traits of a truly high-end speaker, the Prime Bookshelf speakers convey accurate spatial imaging, throw an expansive soundstage and deliver uncompromising fidelity throughout the frequency spectrum. The effortless low frequency extension, commanding but detailed midrange and airy, unveiled highs far exceed expectations of other speakers in its class. Even the cabinet geometry and internal bracing are optimized for uncompromised audio playback and complemented by stunning piano gloss and black ash finishes.
