Each DALI Speaker system is conceived through this simple, yet rigorous, design procedure:
1) Determine the physical size of the speaker cabinet.
2) Calculate the optimum relationships between the internal cabinet dimensions to diffuse standing waves and minimize their amplitude.
3) Select the optimum size woofer for the given cabinet size.
4) Calculate all woofer performance parameters, such as moving mass, magnet mass, suspension compliance, mechanical Q, electrical Q, etc.
5) Design a complimentary tweeter and midrange for optimum integration with the selected woofer.
6) Determine precise driver location for optimum dispersion and minimal diffraction effect.
7) Measure all drivers for distortion, frequency response and other performance specifications.
8) Calculate theoretical crossover systems for flat frequency response, proper phase response, and other critical performance specifications.
9) Make extensive detailed measurements of complete system performance.
10) Refine crossover for most accurate frequency response.
11) Conduct initial listening test.
12) Based on the results of first listening tests, we decide how far back we most go in the development process. At that point we go through all measurements in the laboratory again.
13) Conduct second listening test. These are usually simpler than the initial tests because most of the problems have been eliminated.
14) Sequence 12 and 13 are repeated over and over again until the panel of listeners is completely satisfied with the new DALI system.
DALI SPEAKERS
DALI 2
Although the DALI 2 is our smallest speaker, it faithfully exhibits this part of our philosophy. Its 6 ½” two-way configuration provides extremely accurate reproduction over the entire operating bandwidth. On-axis as well as off-axis response of this little speaker are within the studio monitor limits of +-3dB for the 68-20,000 Hz (30 degrees 18kHz) range.
DALI 3
The DALI 3 is a two-way 8” design which employs a high performance woofer and 1” voice coil, feerofluid injected dome tweeter. This system delivers an exceptionally fine performance with a clear, articulated reproduction of even the most complex musical waveforms.
DALI 4
By incorporating a dual 8” woofer configuration, the DALI 4 provides a significantly better bass response and power handling than other more compact models. The symmetrical woofer alignment also allows improved stereo imaging and increased dimensionality.
DALI 6
Without question, the DALI 6 is one of a few true world class loudspeaker systems currently available, regardless of price concerns. The DALI 6 utilizes a closely integrated three driver system including a 10” woofer, a 8” upperbass/midrange, and a 1” voice coil dome tweeter. The 8” unit extends its response up to the tweeter’s crossover point, while the 10” woofer rolls off at 1500 Hz. Both units work together – at the same volume – in the low frequency range.
DALI 8
The DALI 8 stands alone among contemporary speaker designs in that it delivers so much performance at such a reasonable price. The DALI 8 embodies the latest DALI engineering innovations, incorporating dual 8” long fiber pulp woofers, a 4 ½” midrange, a 1 3/8” dome tweeter, and a ¾ “ ultra high frequency driver.
