Audio Pro Blue Diamond Floor standing speakers
Everything in the Swedish Image Series Blue Diamond excites interest in the owner of such an expressive and promising name - the authority of the Swedish Audio Pro, and the refined polishing of the heavy and strong, as if basalt, body, and extraordinary design, and high technology. In the "Blue Diamonds" the famous proprietary control system of bass driver parameters - ACE-Bass, that allows you to effectively manage the quality factor of the woofer is used. You can connect the speakers to both high-level and low-level outputs. There is a level control for the line input, which will be useful if you need to remove the signal from the preamp output. The "Master Level" knob changes the volume when the subwoofer is connected to the high-level output of the power amplifier. Note, just in case, that the polished surface of the Diamonds is extremely sensitive to the touch of your fingers and requires constant care.
The system belongs to the category of those representatives of "subwoofer" speakers, which, even with the active section turned off completely, create quite a mature sound image in terms of the completeness of low-frequency content. This image is picturesque, somewhere even aggressive in a good way. The brass and strings sound very effective and lush. Negative consequences of a little bit increased attention of the system to the lower top are almost completely removed by the excellent dynamics and good purity of the whole image. The bass is focused on detail of moderate depth. It took a while to adequately activate the subwoofer. Slightly twist the knob and a dense wall of bass obscures all the content of the lower middle, do not twist - and from the low-frequency flesh leaves the salt and life-giving moisture. Yet, when the regulator hand stopped near "12 o'clock", a long-awaited miracle happened: the sound of a living double bass string suddenly emerged from the complex musical mass; and even when its "plucking" periodically put the characteristic "plugs" in the ear pads, a free middle was playing in all colors of the rainbow. One listened wonderfully to jazz, and spectacularly and vividly to symphonic classics. Rock compositions make an indelible impression in the system's performance. "Diamonds" perfectly produces all low-frequency "theatrical" effects and in this ability can compete on equal terms with almost any independent subwoofer. The volume control can be handled much bolder here.
When using the speakers in small rooms for purely musical purposes, it is really possible not to include an active subwoofer. If, however, there is a need for deep musical bass, the subwoofer should be set up responsibly, and in this case it is better to slightly underpower the low frequencies. With proper tuning, the Blue Diamond will create an expressive adequate musical image of the work of any genre.
