hi, i have a pair of polk audio speakers, the "5jr monitor series".

im selling them so I need info about:

-watts
-rms
-impedance
-frequency

thank you...

:p :p :p

i'll be waiting for a reply ;)

Watt : Is the unit of power used to rate the output of audio amplifiers. For a wattage number to have meaning the distortion level and impedance must also be specified.

Rms : (root-mean-square): The square root of the mean of the sum of the squares. Commonly used as the effective value of measuring a sine wave's electrical power. Even though a technically incorrect term (watts continuous is correct), it has become a standard in amplifier measurements.

Impedance : Impedance is a measure of electrical resistance specified in ohms. Speakers are commonly listed as 4 or 8 ohms but speakers are reactive devices and a nominal 8 ohm speaker might measure from below 4 ohms to 60 or more ohms over its frequency range. This varying impedance curve is different for each speaker model and makes it impossible to design a really effective "generic" speaker level high-pass filter. Active devices like amplifiers typically have an input impedance between about 10,000-100,000 ohms and the impedance is the same regardless of frequency.

Frequency : The range of human hearing is commonly given as 20-20,000Hz (20Hz-20kHz). One hertz (Hz) represents one cycle per second, 20Hz represents 20 cycles per second and so on. Lower numbers are lower frequencies

Now, go peddle your speakers to the masses (elsewhere).

Cheers,
Russ

Thank you for your answer, ;)

but, i need to know the specs of the 5jr monitor series.

i mean, watts, rms, impedance, frequency.

thanks again russel, i really didn't know the meanings of all these terms, but now i do
:p
