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?

4 and 8 ohm taps. I am using the 8 ohm taps for both speakers!

Thanks for that site!

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

Hi Ralph,

Thanks for the great explanation of why the 15 ohm Falcons play louder than the 6 ohm Harbeths. You are a real asset to the Audigon community!

I sold the Q7. I was using Quicksilver 70 watt tube amps with Audioquest cables. The Q7 is as good as any of that type of speaker. I replaced them with the larger Harbeth HL5 super plus. The Falcons are very lively forward sounding compared to my Harbeth P3esrs. BTW, after the holidays I will be selling the P3s. I hope the Falcons work out for you!

@brianportugal

I think a larger speaker in that size room would be overwhelming. I have owned the Harbeth C7 and the M30.1 and I preferred the P3 in my 20x15 room sitting 8 feet away. About 3 weeks ago I pulled the trigger on a used pair of the HL5 with TonTrager stands figuring if they didn’t work out I could resell them without a loss.

To my surprise these are the best sounding Harbeths that I’ve owned. The seller found them bright but I sure don’t. You never know until you try a speaker in your room and gear how it will sound!

BTW, have you ever listened to the P3ESR?

@brianportugal

It sounds like you have fine gear with those Falcons so I really can’t suggest changing anything. I prefer 2 way standmount type speakers. It surprised me that I like the HL5. I haven’t had a 3 way speaker since Vandrsteens many moons ago. I really don't miss any of the speakers that I have owned but I must say that I had a Spendor 2 1/2 way floorstander that I should have kept. BTW, those Falcons are a bargain compared to the many other she box size speakers out there. Enjoy them!
