Dana 640i stand monitor loudspeaker
Serious performance for much less than expected
The new Dana 640i is part of the second generation of precision Dana loudspeakers and the first Dana 600-Series stand monitor with a large, 165mm / 6.5" midwoofer. The all-new 640i's long-throw midwoofer is performance-tuned in a classic bass reflex alignment and its 25mm / 1" soft dome tweeter perfectly compliments it (and other Dana models) through a precision dividing network. Both Dana 640i drivers use special technologies that truly set them apart from anything we're aware of in Dana's price class. Each of the two drivers has a frequency response at least a full octave beyond expected standards for the class, along with the proportionally lower distortion that only these technologies can provide. Dana's special combination of very high driver linearity is a first for such affordable models.
Ultra-high resolution from an affordable, premium Internet-direct loudspeaker
Costing less than speakers an entire performance class under them, the new Dana 640i are mirror imaged and ship in matched pairs. The 640i are finished in genuine European matte-finished, filled-grain cherry and exceed the usual quality of the reference loudspeaker class for anywhere near their cost.
Exclusive features
- Very low distortion driver motors for both tweeter and midwoofer give the 640i superlative musical detail
- Tweeter response to beyond 40kHz for excellent phase response in the audible band
- Raw papyrus midwoofer cones and ultra-linear suspensions along with extremely low inductance motors give the 640i's midwoofers a raw response to 10kHz
- Cast alloy midwoofer basket is completely ventilated for excellent linearity and power handling
- Bass reflex enclosure type, tuned for best bass control without the bass "lift" common to so many speakers
- Heavy, braced, damped cabinet finished in genuine polished cherry veneer
- Rear ported. Matched, mirror-imaged black knit grilles are removable. Stainless hardware. Single-pair input terminals in heavy gold plating
The new Dana 640i is a dramatic entry into the very high value loudspeaker category - we challenge you to find sound like this anywhere. With The Audio Insider, you'll save substantially - the quality and sound of the Dana 640i is rarely available for under $2000 the pair. Compare them to any premium stand monitor you choose.
Dana's 25mm dome tweeter has a usable response to nearly 40kHz.
Dana's very high performance midwoofers have less motor distortion than anything in Dana's class.

Dana technology
Tweeter
All Dana 600i-Series main speakers (the "i" designates "Improved" in this, the second generation of Dana loudspeakers) use a very high performance 25mm soft dome tweeter. This special dome tweeter has response to beyond 40kHz, and a remarkably flat, non-reactive impedance magnitude for low distortion. These characteristics are remarkable and truly transform the driver ... and only Dana has them in its price class. The Audio Insider selected this tweeter for these attributes and we believe they make this device unique to the Dana 600i-series class - you won't find this level of performance at this price elsewhere.
Dana's tweeter includes a European silk dome, special low-inductance motor with copper plating for very low distortion and very wide bandwidth, a high-energy motor, tuned rear chamber, special low-distortion suspension, and optimized dispersion. As the diret result, 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 special highly upgraded midbass and bass drivers for best performance and acoustic match. Each model has a hard-struck raw papyrus curvilinear cone balanced in a linear, low loss, low distortion suspension using a low-loss front edge suspension and a large flat rear spider. Frames are cast alloy, and feature a completely ventilated motor, both under the suspension and through the pole piece. Special copper shorting devices in the Dana motor give Dana midbass and bass drivers literally the lowest magnetic distortion we've seen in 30 years, and this excellence reveals itself in Dana's remarkable new sound.
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, and Dana models uniquely have a high degree of "downward dynamic range" or the ability to mine the recording for previously unheard information. All models are precision-tuned bass reflex alignments for the best bass possible.
Crossover networks
As a premium product from a reputable 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, non-inductive resistors, and low loss inductors complete each circuit.
Cabinets
A great European-style 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 and all panels are milled to final tolerance by computer-controlled machines - hand-cutting cannot ensure Dana's perfect fit, finish, and unit-to-unit consistency. Enclosures are internally braced for strength and damped with up to three kinds of internal damping for sonic inertness. Final finishing involves a filled-grain, glass-flat surface polished to a medium lustre for lasting value and a look as harmonious in your decor as Dana sound is to your ears.
