Hi All

 

I am currently running 2x Dap Audio speakers through a pretty ancient old amp. I am looking to replace this and would like your advice. The speakers state they are 400w @ 8 Ohms. Does this mean they only run at 8 Ohms? So would i be correct in presuming i need a 800w amp? Something like this ?

Ohms is a measurement of electrical resistance. The lower the ohms the less the resistance so a 4 ohm speaker will draw more power from an amp than an 8 ohm speaker. If speakers say they're 8 ohms then they're 8 ohms, nothing else. It's the amp you need to look out for. That amp you posted runs at 400 watts a side but only with 4 ohm speakers connected. It probably only runs at 200 watts with 8 ohm speakers.

 

You could connect two 8 ohm speakers on the same channel which will make the amp run at 4 ohm but still, each speaker will only get 200 watts each.

Got a model number / link to the speakers in question? Is it 400w RMS @ 8 Ohm or 400w Program @ 8 Ohm ?

 

The "maths" of working out the RMS of a speaker is similar to the following example:

200w RMS = 400w programme = 800w Peak

 

If your speakers are 400w programme, then that DA800 amp would be powerful enough (It provides 250w RMS per channel into 8 Ohms), which leaves you a bit of headroom (so no need to turn it all the way up = cooler running Amp which usually means it'll last longer).

 

 

Cheers,
