When is my volume too loud? A volume above 80 decibels can be harmful to hearing. When the volume exceeds decibels, direct damage can even occur. The chance of hearing damage depends on the listening frequency and duration.
What is HDMI? An HDMI cable is used to transport audio and video signals between devices. How can I best clean my Soundbar? A slightly damp cleaning cloth or soft, dust-free cloth works best to remove fingerprints. Dust in hard-to-reach places is best removed with compressed air. Wat is Dolby Atmos? Dolby Atmos is a technology that ensures that the sound is reflected from the ceiling to where you are listening.
This makes it possible to create a 5. What is bluetooth? Bluetooth is a way of exchanging data wirelessly between electronic devices via radio waves. The distance between the two devices that exchange data can in most cases be no more than ten metres.
Is the manual of the Polk React available in English? Yes, the manual of the Polk React is available in English. The connectors accept single or dual banana plugs, lugs, or stripped wire ends. Including the port radiation, the bass extended down to 20 Hz within the same limits, but under actual listening conditions the effective bass extension will depend on the speakers' environment.
In our room, the audible response was clean and usable down to about 35 to 40 Hz. Polk rates the LS's response as 3 dB down at 37 and 25, Hz. Although we did not test beyond the audible range, these figures are consistent with our results. Impedance measured a minimum of 4 ohms at about Hz, rising to 15 or 16 ohms at 60 and 1, Hz. Polk says the speaker is "compatible with 8-ohm outputs," and it is, but we would rate its nominal impedance at 4 to 6 ohms.
Sensitivity with a 2. With 2. At 1, and 10, Hz, the LS easily absorbed the maximum output of our driving amplifier with a single-cycle tone burst, reaching watts at 1, Hz and 1, watts at 10, Hz. At Hz, the woofer sound gradually took on a sharp, rapping quality as the power was increased beyond a few hundred watts. We stopped at watts, though we hadn't yet reached the physical limits of the drivers. The tweeter's horizontal dispersion was typical of a good 1-inch dome radiator, with the output 45 degrees off-axis down 2 dB from the on-axis readings at 5, Hz, - 6 dB at 10, Hz, and -9 dB at 20, Hz.
Quite apart from the LS's measurements, which indicate that it is a very fine speaker, how did it sound? In a word, superb. Its spatial imaging, both lateral and vertical, was outstanding. Imaging tests using the Chesky JD disc produced what was probably the most accurate localization we have yet experienced from a pair of speakers playing that CD. There was a completely unambiguous placement of the sound in accordance with its announced position.
Many speakers do a reasonably good job in this test, but the LS's put the sound exactly where it belonged. Another interesting property of the LS was that it sounded natural and listenable even at a distance of only a foot or so. Although stereo imaging is lost when you listen that close, the sound quality remained as unified and balanced at 1 foot from the speaker as at 10 feet this quality is not typical of most loudspeakers we have used.
And that sound quality, under more normal listening conditions, was notable for its smoothness and balance. There was occasionally a slight tendency toward warmth, but the flatness of the overall response generally prevented the bass from dominating the system's sound. Nevertheless, when the program material called for it, the LS put out a quantity and quality of bass that belied its modest price.
