Sensitivity question
I need a little help in trying to understand some basic concepts with speaker sensitivity. I understand that an 8 Ohm speaker rated at 88db (or less) can be a little hard to drive---and 6 Ohm can be harder. I get that----but on some small British speakers, they can be 86db but rated at 10 Ohm. So my question is this: is a 86db, 10 Ohm speaker hard to drive or not? Can I run them with a 23 wpc Class A amp? Thanks in advance.
Hoffman’s Iron Laws of Speaker Building1) Bass Extension 2) Efficiency 3) Small Enclosure The law is that you can only have two of these three attributes in speaker building. Ideally, we would want all three, we want speakers with good bass, can play really loud, and are small. Unfortunately, we cannot have all these. |
Thanks for all the great responses---it was a huge help! @ditusa Great article!! |
I drive a pair of 83db speakers with a class A 28wpc amplifier. Normally I would have never even thought to do this but since we do audio repairs, the amp came in and to test the repair we hooked it up. It drove the speakers better than many other amplifiers we typically would use. So give it a try and see what happens. Happy Listening. |
