One speaker louder


What could cause one speaker of a consecutive pair to sound brighter than the other? Both tweeters are working but one speaker sounds a little louder and sharper. A slight but noticeable difference.

Assuming you checked your source/amp then Room Placement can play a small role. If you are listening to CD's then quite often the balance is such that sounds are divided in the soundstage - some left some right.
Have you tried swapping the speakers from left to right? Just a thought, it could be a channel imbalance in the amp.
One possibility is room acoustics relative to the placement of the speakers and your listening position. Window glass, differences in furniture upholstry, wall hangings, rugs, etc. can affect sound.
Assuming that you have indeed confirmed that it's the speaker and not something else, that is, you've swapped them left for right and the sound follows the speaker, then there are only a couple of possibilities:

1. Damaged speaker - a failure in the crossover network could easily cause what you describe, but occasionaly a driver failure will cause it as well.

2. Manufacturing tolerances - just because they're consecutive serial numbers or a supposedly "matched pair" doesn't mean they were perfect to begin with. Speakers are made by people, and people make mistakes.
are you using tubes?????? If so its possible one channel is dying slowly.......Check your speaker cable fittings...Try switching speakers ( leave everything else the same )..Just a couple things..Hope they help...........
Swap the speakers (not the cables) and see if it follows. If it does not, then I'd say room acoustics. If it does, then the manufacturer is having QC issues.

Ken Kantor (founder of NHT) stated in an interview long ago that anyone can build one great speaker. The hard part is getting all the speakers in a line to closely match the reference.
i had the same problem for a while it just takes a lot of patients. it is all about first reflection and speaker placement
I agree with swapping speakers left to right as a troubleshooting technique. This may tell you if the problem is a speaker or something else (placement, electronics, source material).
I swapped them, but there is a real difference. You can still tell they are the same speaker, but one is quieter and less open.
If the quiet and less open speaker follows the swap, then the problem is the speaker, and not placement, equipment or source material.

If the swap results in the same channel sounding quiet and less open, then the issue is with something other than the speakers.

IMO.

Bad news. Next step (if new or recently purchased) is to take grills off and check no packing material is in the way - also check to see if a driver is completely dead and then contact the seller. Otherwise - you might be able to open them up and check connections and contacts and the crossover. What model are these?

Any chance you overdrived them - even briefly by mistake?

Finally you are looking at a repair or replacement driver...

I swapped them, but no difference. You can tell they are the same speaker, but one has an airy quality, the other is more mellow.

A dead or half dead tweeter perhaps?
Is there tone generating software that I can use to listen to high frequencies of both speakers?
This one should work well.
