What is the out put impedance? Thanks KP Jandt

Not sure this helps, but I have used it to drive pre-amp audio in, electrostatic headphones, and hi-end (40 ohm?) earbuds, works fine for all three

It depends on the speakers, most consumer speakers are 8 ohm and would be connected to the 8 ohm outputs. Some commercial speakers are wired in series and are equipped with a 70 volt transformer and would use the 70 volt connection. Most speakers have the impedance printed on them.

They have an eight ohm impedance. The Polk website has a very complete list of the specs.

Check the Polk Audio website for the specs http://www.polkaudio.com/mm651/d/1151 . According the their specs - Electrical - Nominal Impedance 2.7 ohms

The impedance with the high and low range terminals connected in parallel with supplied connectors (recommended default setting) is 8 ohms. The speakers can be driven with an 8 or 4 ohm amplifier. Most receivers are 8 ohms. I am driving them with an amplifier designed for 8 ohm speakers and they sound great. There should sound just as good connected to a 4 ohm amplifier. Basically the impedance of the speaker should be equal to or greater than the minimum rated impedance of the amplifier.

I would say refer to the instruction manual as well. I found this interesting paragraph in the manual to a circa 1998 Marantz receiver that I have whose speaker outputs are labeled "8 ohms": Note on loudspeaker impedance: The power ratings specified for this Marantz receiver are obtained using fixed value test load impedances. However, the actual impedance of a loudspeaker system will vary with frequency, deviating from the nominal rating. This Marantz amplifier will drive any modern loudspeaker system with a rated impedance of 4 ohms or higher. A few newer loudspeakers feature impedances of less than 4 ohms. The high current output capability of this Marantz receiver can provide the additional power necessary to drive such low impedance speakers. However, during extended passages of high volume, the protection circuitry may temporarily interrupt operation. If this occurs, simply reduce the volume accordingly. The protection circuitry is specially designed so that it cannot affect the sound quality during normal operation.

I haven't actually measured it, but I have to assume the output voltage is very stable when the input voltage is within the specs of the device ... that's the whole point of the device.

The nominal impedance is 8 ohms. As a note, the impedance is 4 ohm up to ~70Hz, which it climbs up to 12 ohms at 100 Hz and soon drops back down to 4 ohms at 200 Hz, then does the slow climb to ~9 ohms around 5-6kHz, and trends slowly to 4 Ohms again for the rest of the audible range. If you're just looking to see if this speaker can work for you, don't worry about the nominal impedance. If it isn't a completely off-the-wall audio setup and you're going to be listening at below 100dB levels, you won't hear any distortion (unless you're a Labrador) and you won't cause the receiver to run too hot.

Producer do not report impedence. I used with a 4 ohms system and it works fine.

Specs. SPL 110 (+/- 3dB) @ 1KHz @ 1 mW Input. Freq. Response 18Hz - 22KHz. Rated Input 10 mW. Impedance 32. Dynamic 40mm Dynamic Driver w/ Neodymium magnet. Hope this helps. ...Blessings!!!.

I do not have the ability to measure the output but I read somewhere that the tolerance is tighter than what you state.

failing to match impedance causes the signal to be reflected back - heating output amp. So use low power and all is well, Or add a 4 ohm resistor to match and this problem goes away - low volume. Better yet use an 8 ohm speaker.

richard all i know is what is listed in the description doesnt give me a amp output sorry

There is a setting on the 573 to set speaker impedance to 6 Ohms. See p 80 of the owner's manual. http://download.yamaha.com/api/asset/file/?language=it&site=it.yamaha.com&asset_id=54064

dual 2 ohm and you can always download or go on Rockford fosgate website and can get a wiring diagram for x amount of subs and ohm load and it will tell you final ohm load

Impedance is the resistance or load that the speaker presents to the amp. Most amps do fine when the speaker is 4 ohms. If the speaker presents a 2 ohm resistance to the amp the output of the amp doubles because it's pushing against half the resistance. Some amps may not be stable at 2 or even 1 ohm. As the impedance goes lower output increases, but you can lose sound quality, and if it is very low you can sometimes damage equipment. You can also look up series and parallel wiring if you're going to wire more than one speaker into each input. The alpine speakers here are 4 ohm speakers. This means they are safe for most amps/ radios. Definetly all aftermarket radios.

The manual says the the unit will prevent the impedance presented to your receiver from dropping below 5 ohms, regardless of the number and impedance of speakers connected to it. However, I don't recommend the unit as on the one I got two of the switches would not stay pushed in. I only use it for 2 sets of speakers so it's okay, but two switches are clearly defective. Impedance matching must be turned on for it to perform as stated above. Good luck.
