Default Are my Speakers efficient enough for my Amp?

I have a Lafayette 224A amp that I recently purchased and a pair of Cerwin-Vega L-7 speakers that I bought back in the early '90s.

The amp puts out about 6WPC and my speakers are rated for power handling of 75 watts/8 ohms and sensitivity of 92dB.

Are my speakers efficient enough to be driven effectively by this amp?

You should have no problems driving those speakers unless you play ear splitting hard rock....

I agree with Sal. 6 watts is 7.8dB so with one 92dB speaker you can achieve about 99dB. You have two of them so add 3dB. You also have two channels of amplifier power so add 3 more dB. You are now at 105dB. SPL falls off by 6dB every time you double distance, 2 metres rather than one metre for example, in free space. You are not in free space, more than likely, you are in an enclosed room. In an average listening room I would expect you to be within 6 or so decibels of 1 metre readings in your listening position. So, you should be able to get close to 100dB SPLs in your seat. That is more than enough for acoustic, unamplified music. If you listen to extreme rock music that is intended to be heard at 100+ dB 6wpc probably wouldn't be sufficient, but I have a feeling that if you were listening to that you wouldn't be asking this question.

Thanks for the input guys, i am glad to know these will work well with my amp.

The speakers have been in storage for 6 years now and I am excited to finally be able to use them again.
