8 Ohm Speakers


I understand that speakers less than 8 ohms require more power and will overheat and possibly clip low powered amps. I also understand that my integrated amp runs 60 watts into 8 ohms and 100 into 4 and is not recommended power beyond that. But what are the consequences of driving say 10 or 14 ohm speakers? Is it just less work on the amp? Like the sensitivity, will it play speakers better at lower volume? This may be a naive question but its been ringing around in my head. Thanks in advance.

Jaica: Thank you for your response. I guess what has me confused is that at some point my solid state amp won't be effective with a speaker (if it exists) with a 2 ohm resistance. Now can the same be said going the other way, higher resistance? I notice when I play my 32 ohm headphones the volume must be doubled and I assume at that point the 60 watt amp is only pushing out 15 watts. So just like tube amps must solid state amps be matched to speakers, but for different reasons?
Not all tube amps have problems with 4 ohm load. My Audion Silver Night definately does not and neither did an early version of the little Decware amp that I played around with late last year (it actually performed better, IMO, into a 4 ohm load as the bass was fuller and tighter). Each amp and speaker combination really needs to be auditioned to to tell the true story as the numbers are often misleading, as is the general folklore of such supposed matches. In addition my old Mac 30's also sounded great with 4-6 ohm loads however my Musical Fidelity SS amp would not control the bass on pair of 4 ohm Linn Tukan's, go figure.
Dekay, which model is your Musical Sidelity SS amp? I'm just curious if it is the one I have.
Big: It is the X-A1 integrated that would not handle the bass on a pair of Tukans that a local dealer loaned us (I ended up with the speakers almost out to the middle of the room and kept saying "It must be the room, It must be the room":-). My tube amp is in the shop right now and the MF amp does a fine job with a pair of Reynauds (also 4 ohms and basically the same specs as the Linn speakers. You never know till you try.
These rules are all just fine "all other things being equal" like with all theories. I came across a pair of valve amps made in Korea some years ago. The only tap on them was 8ohm. I tried them on both my sets of speakers at the time - both 4ohm from Thiel and Martin-Logan. They sounded fantastic, so I bought the amps. Since then I have surmised I should get a good pair of 8ohm speakers and hear what these babies can really do. The result was disappointing, but with the good news that these amps sounded equally at home on 4ohm and 8 ohm speakers. I have even continued to try solid state amps on my speakers and am always disappointed that they don't generate the excitement and emotional involvement with the music as the tube monos do, and offer no real improvements in the bass.
