Dana technology
Tweeter All Dana 600-Series main speakers (except the 680) use a high performance 25mm Danish style soft dome tweeter made for Dana by Vifa. Since their performance and value are so high, Vifa tweeters are possibly the most widely known (and copied) tweeters in the premium driver category. Dana uses original Vifa technology article and does so at an attractive low cost.
Dana's Vifa tweeter includes a European silk dome, high-energy motor, special low-distortion suspension, and optimized dispersion. All Dana speakers have high frequencies that are neutral, open, spacious, and relaxed-sounding. The 25mm Dana dome tweeter also has high power handling, wide dynamic range, and excellent dispersion, features rarely found at Dana's low price.
Midbass / Woofers Dana also uses Vifa midbass and bass drivers for best performance and acoustic match. Each model has a hard paper cone material and linear, low-distortion dispersion. Like all speaker models in the premium category at The Audio Insider, Dana speakers have a wonderful balance of neutral response, wide bandwidth, and low distortion. Larger tower models feature long throw and linear suspensions, and all models sport precision-tuned bass reflex alignments for the best bass possible.
Crossover networks As a premium product from a reputable Danish maker and brand, Dana models all come with highly optimized internal dividing networks and filters, each CAD-developed and tuned by ear with care and expertise. Danas voicing is musical and articulate, and does wonders for either music or home theater program material. High-grade polypropylene capacitors and air-core inductors complete each circuit.
Cabinets A great European loudspeaker brand is certain to include impeccable sonics, but Dana includes equally impressive furniture-grade cabinetry in the tradition of the best Danish-modern style. All cabinets are genuine hardwood veneer in a choice of natural European Cherry or clear Maple Burl. All enclosures are milled to final tolerance by computer-controlled machines - hand-cutting cannot ensure perfect fit, finish, and unit-to-unit consistency. Enclosures are internally braced for strength and sonic inertness. Final finishing involves a filled-grain surface polished to a medium lustre for lasting value and a look as harmonious in your decor as Dana sound is to your ears.
