Any body know of an integrated amp that is 100 watts into 4Ω ohm? Plenty in 8 ohm But can't do it in to 4 ohm.

 

[legrandefromage]

Well, if you look into it, 100w @ 8 Ohm would be around 200 Watts into Ohm

true. But so few manage that. Except Krell. Which are beyond my £££. One on ebay for £950 that is 150 watts +

https://www.cambridgeaudio.com/gbr/en/products/hi-fi/cx-series-2/cxa61 this goes to 90 w But my new speakers are 86 d in 4 ohm and are hard to power. So it's recommended 100+

Physics and electronics technical wimbury woobury says that an amplifier rated at 60w into 8 ohms max output will be around 120watts when given a 4 Ohm load/ speaker

For Real World amplifiers this sits at around 80 watts into 8 ohms to give you your 120 watts into a 4 Ohm load

Unless you are running Magneplanars which are almost a short circuit!

 

[legrandefromage]

So your speakers make the amplifier work harder, drawing more power from the amp

 

[legrandefromage]

Just about any amplifier will run your speakers, that 86db is for 1 watt of power at 1 metre, 5 Watts will be at around 88db at 1 metre away from the the speaker

That rating of 100w is simply there so that you can run the speaker safety at high volumes without damage to either. It's very rare that anyone needs to go full on, any amplifier with a good quality power supply will be suitable up to modest volumes. It can then supply the current that your speakers need
