Speaker efficiency??

**BerserkNitro** · **01-31-08, 10:33 PM**

Hi all shacksters....How can i tell what my speaker efficiency is? And dont tell me to look on the back....because theres nothing on the back..I know that there 6 ohms thats it..

And the vintage..iam thinking late 70's early 80's and i might be wrong.. made by RtR..

Well if you had a way of measuring you would send exactly 2.45V of white noise into your speaker and measure with a calibrated mic from 1m away and that would tell you your sensitivity for a 6ohm speaker. You could probably achieve this using a digital multimeter and slowly turn up the volume until it reads 2.45 volts though I may be wrong considering this is an AC system so Ohm's laws doesn't apply exactly???

Why do you need to know the effeciency? Dennis

Because iam thinking of running tube amps...And i have read you need high effecient speakers..

True, the less output power you have, the more you need efficient speakers. Have you tried them with the amp yet? Dennis

Not a tube amp..But i used a B&K 200.2 reference amp and it sounded good but i sold it and now iam for a new amp! And i like the sound of my friends amps..two mono blocks.I believe there McIntosh amps but not positive on that!
