I need 4 ohm speakers for my Warrior IS600 Amplifier


It is rated as a dual 300 watt amplifier, shich strongly suggests a Class D peak value for each amplifier.

In theory- 100 watt RMS 4 ohm speakers should be adequate.

hi,
You have to check the ohms of the speakers all spekers should be 8 Ohms or above. if not it will overload the amplifier at high level. The minium ohms impedence of the amplifier is 4 ohms. If you connect two 8 ohms speakers together then the effective ohms will be 4 OHMS then the amp will handle the speakers. If you connect two 4 ohms spekers together then the effective ohms will be 2 Ohms, this will overload the amplifier. You will be able to connect two 8 ohms speaker to left channel or right channel of the amplifier. Check the speaker spesifiction to know its ohms. Make sure all the speakers have an impedence of 8 OHMS or above
OK

I have a plad213 what load impendance am i running it i hook up 2 4ohm speakers in series bridged on that amp and how many watts RMS am i getting per speaker


2 4 ohm speakers wired in series is 8 ohms and then is dropped back down to 4 ohms when you bridge it.

2 4 ohm speakers wired in parallel is 2 ohms then dropped down to 1 ohm when bridged
(most amplifiers will not handle loads below 2 ohms)

hope this info helps

Appropriate voltage for PS-57


Speakers don't use a voltage level to determine their usage- they use an "ohms" rating, like 4 ohms or 8 ohms. Ohms is written as an omega symbol. You have to match the ohms rated output of the computer to the speakers, or you can either blow the speakers up, or overload your amplifier and burn something up (usually a transistor). The power rating is also used to match components (expressed in watts, or the letter W). You can use a higher power rated speaker with a lower power rated amplifier, but you have to be careful of the opposite case. At some point at the upper end of the volume knob, you will draw too much current and blow the amplifier. Most people do this because it used to be that loud, etc., but in reality, you will never get the same volume with a lower power rated speaker system, and trying to will jepeordize your amplifier. I searched the net, but noone had any technical info on them, but I did see some pictures. My guess is that they're 8 ohm speakers with a very high power rating. Just make sure your amplifier is rated 8 ohms too, good luck! (P.S. if you're amplifier is rated 4 ohms on the output, I would recommend getting an 8 ohm output amplifier on ebay, in the event the speakers are 8 ohms) Hope this helps.

6 ohn wharfedale speakers on an 8 ohm TEAC amp (both old) - will that work


Yes. Most if not all speakers have impedances which vary with frequency and are rated at a nominal or average impedance. So a manufacturer who rates their speakers at 6 ohms may be more honest or chooses to quote it at a specific frequency. So a nominal 8 ohm speaker may actually measure 4 ohms at 100Hz and 12 ohms at 500Hz but averages somewhere nearer 8 ohms. It is normal for most speaker manufacturers to simplify their ratings so speakers which average at say 6 ohms would be categorised as 8 ohm, and 4.9 ohm averaged speakers as 4 ohms.

As a point of interest - some amplifiers are specified as providing their maximum power at impedances of 6 ohms, and there fore some speaker makers (including those made by same manufacurer as amplifier) will rate their speakers at 6 ohms so they appear more compatible.

As far as I am aware you need to get 2 ohm speakers. I run a 4 ohm subwear as the Alpine Type R sub is 2 ohms. I'm not 100% on this though but you may get around it by bridging your speakers by connecting both speakers to the amp as normal but swapping the speakers negatives around! That may cause the amp to run as if only at 2 ohms. Hope this helped!
