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.

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.

Prime Driver & Tweeter Design

Thoughtfully designed for acoustic excellence, the Prime Bookshelf speaker’s 6.5-inch woofer is mounted in its own dedicated and completely sealed compartment to ensure smooth, precise and clear midrange and bass output that’s free from coloration. The cone material is extremely light and rigid and maintains a flat frequency response with excellent handling across the foundational mid-range frequencies. Low frequency extension is shockingly deep and effortless considering the cabinet size and the Prime Bookshelf speaker can hit reference volume with amazing clarity, no distortion and headroom to spare.

The Prime Bookshelf speaker’s 1-inch aluminum dome tweeter is light, efficient, and rigid, and plays crystal clear at high volumes. The clarity offers a sense of utter transparency, while offering an ‘airy’ presentation and incredibly unveiled highs so female vocals and dialogue and high pitched sound effects and musical content always sound crisp, smooth and natural.
