mixed speaker set up
Hi,
I've recently been given 5 speakers from a home theatre set. 1 - Centre 220W @ 8ohm (music) 110W @ 8ohm (din) 2 - front towers 240W @ 8ohm (music) 110W @ 8ohm (din) 2 - surround rears 110W @ 4ohm (music) 55w @ 4ohm (din) Was wondering if anyone knew why there are two ratings, one for music and one for din? i've never seen this on speakers. Secondly, will a receiver rated for 110W @ 8ohms all around be okay to use on this? I'm looking at the yamaha 5830. I'm assuming yes since the 4ohms is less resistance and shouldnt overheat the receiver. Any help would be appreciated. jason |

There are actually two or more systems for rating audio power. One is called, I think, IHF Music Power and the other is apparently DIN (Deutsche Industrie-Norm = German Industry Standard). That's what they refer to. (Sorry, my knowledge of these is not up to date.) i've never seen this on speakers. Secondly, will a receiver rated for 110W @ 8ohms all around be okay to use on this? I'm looking at the yamaha 5830. I'm assuming yes since the 4ohms is less resistance and shouldnt overheat the receiver. 4 ohms is less RESISTANCE and draws MORE current. Check whether the amplifier can drive 4-ohm speakers. If not, do not use them. Most amplifiers will drive speakers with a resistance of 4 ohms and up. Some are only for 8 ohms and up. This should be marked on the back of the amplifier. As long as you don't turn the volume all the way up, everything should work fine. It is common for the wattage of the amplifier to be different from that of the speakers, either higher or lower. The power actually coming out of the amplifier is far less than its rated wattage almost all the time. |

Just a technical spec to cover their ass. greg As long as you don't turn the volume all the way up, everything should work fine.

Look also for the wording "two channels driven", it is likely to be somewhere in the small print adjacent to the power specs. It is not as fraudulous as it may seem, because film sound will rarely ever use max power in more than two fhannels at a time, so by aiming for that they get maximum actual playback SPL for the component cost. greg Kind regards Peter Larsen -- ******************************************* * My site is at: http://www.muyiovatki.dk * ******************************************* |
