15 ohm speakers yea or nay?


I just bought Falcon speakers that are 15 ohms. I have Harbeths that are 6 ohms. Both have the same sensitivity rating of 83db. I am using both with the same tube amps.

What has me scratchin’ my head is that the Falcons are much louder with the volume set the same on my preamp.

Any opinions on why a 15 ohm speaker would be that  much different than a 6 ohm speaker with the same sensitivity specs?

The Falcon Q7 are the speakers that I am using. They play much louder compared to my Harbeth P3 ESR!!

Product Reviews

 

 

I believe that many will find that linked article worthwhile.

                                             I hope so!

     The article's SS section should be of interest to those with bridged, stereo amps (being used as monoblocks), when looking for compatible speakers.

                               That's all I would have added.

                          Might be a useful thread, on it's own?
