Does Anyone Know Anything About Speakers?

Can this Denon be used with 20 watt, 4 ohm speakers?  I read somewhere that there is less damage to speakers from an overpowered amp than an underpowered amp (not that I have looked at the amp yet) https://www.richersounds.com/catalog/product/view/id/11935/s/denon-dm41-dab-blk/

Looking at the back of that unit, it states speaker impedance should be 6 to 16 ohms. Yours are 4 ohms, and it's not usually a good idea to use a lower value than stated on the amplifier.

(Very good choice of unit btw. I'd be thinking of matching with other speakers from Richers range..probably 8 ohm. They'll give you very good advice if you ask.)

With the risks of overheating the mini system, or of blowing the speakers, I'd rather not try it myself.

Thanks for the replies.  I wanted to keep my little cherrywood JVC speakers that came with a UX-7000 microsystem bough in Singapore years ago. I did go into Richer's with a view to buying a Ruark R3s.  I`m a bit averse to buying all in one systems though. It's on a small(ish) chest of drawers which is why I don't want anything too big.  I have a DAB adaptor which I have added on but my favourite DAB station has moved to DAB+ so it's time to think about other options.

To deliver 30W into 6 ohms requires an amplifier output voltage of 13.4V rms.

If you were to replace the speaker with one having a 4 ohm impedance, the power delivered into the speaker by 13.4V rms would be 45W – which would almost certainly destroy the 20W speakers.

To dissipate 20W into 4 ohms requires an amplifier output voltage of 8.9V rms – therefore if you ensure that you never turn the volume control to more than 2/3 maximum (with 4 ohm speakers) you should be OK.

Bear in mind that 2 x 20W rms from a stereo system will be quite loud – if you live in a flat it will certainly annoy your neighbours.

Th answer is yes. When you hear distortion turn it down a bit. But you will not realise its potential with those spec speakers.

I just read the What Hi-Fi report and they say that the best speakers for it are Denon ones.
I really think you are wasting its quality with your speakers.
I had a previous  Denon like this prior to switching to Sonos and I used Mordant Short MS10s. OMG, such a lovely sound!
