What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Dahlquist M905 loudspeakers

Dahlquist demonstrated conclusively that some of the classical problems which plagued the delivery of music in the home could be solved. The Dahlquist DQ10 remedied the problems of diffraction distortion and thus made an enormous impact when it was offered to an eager public. It remained the system of choice for many years. Today, it has succeeded by the DQ20, which is eagerly sought by music lovers who insist on having the best there is. Now, Dahlquist  offers a series of highquality speaker systems at modest prices, making Dahlquist  performance available to many more music lovers.

The problem

Speaker systems confined to enclosures have essentially been compromises between high efficiency with wide dynamic range on one hand and smooth, linear, low coloration on the other. Sadly, the latter required a sacrifice of dynamic range and efficiency.

 

The Dahlquist  solution

The Dahlquist  M Series ends the need to compromise. Originally designed for recording and broadcast studios, new techniques now make it possible to offer several models for home use. In the Dahlquist  tradition, the M Series solves many of the problem that still plague other speaker systems.

The Dahlquist  M Series loudspeakers are the first to reproduce all of the subtle, low level details of the music in the midst of extremely high level music signals. The M905 is capable of reproducing the most exquisite nuances available from analog sources as well as the peak high level signals from digitl sources.

 

The M905 delineates soundstage height, width and depth. Its exceptional capabilities are apparent as life-size images in space. A first audition suggests a sophisticated, low-efficiency design. Thus, most experienced and demanding listeners are astonished when they realize the efficiency of the Dahlquist M905

The M905 maintains the traditional Dahlquist  virtues of coherent driver blending and faithful reproduction of harmonic relationships. Moreover, when challenged to reproduce voice, the M905 does so with astonishing ease and accuracy.

Of course, as you might expect from a Dahlquist  loudspeaker system, the M905 incorporates a new and remarkable antidiffraction technique which enhances accurate imaging and contributes to open, spacious, accurate sound reproduction.
