Yamaha NS-10 Problem

[donrey]

I've been experiencing this issue with my NS-10's.... The right speaker sometimes sounds dimmed (as if that channel had been turned down significanlty). I'm able to get it to come back to normal levels by turning the volume up and playing any kick drum with a lot of 'pop' to it (ie. around 90 to 100 hz). Once I play this sound the speaker sounds normal and i have no issues with it. However, the issue returns once the equipment hasn't been used for a while. I also notice that once in a while a humming sound will come from the tweeter. It's not always there and i haven't been able to figure out a pattern.

I'm thinking it could be the tweeter or the cones going bad but I thought i'd post the question to see if anyone else has had this issue...

Troubleshooting I've done:
1) checked cables
2) checked channel on Hafler (tried speaker on the other channel and issue persisted)
3) switched plug hafler was hooked up to.


Current Set Up:

-Hafler TA1600
-Presonus Central Station (with Remote unit)
-Monster cable 3500 power unit

-Mac Pro
-HD1
-192 (i/o)
-liquid channel (connected to the 192 via AES)
-no other monitoring

I would expect electronics over the speaker but it may have a cold solder joint in the speaker

i had this happen yrs back with a BGW power amp.
it was the relay. it would stick and if i hit with a loud kick or a loud blast it would come back.
check your amp.
just a thought

First, switch channels on the amp, both input/output.
If the problem moves, it's not the amp.
If it remains in the same speaker.......
