Help needed!!! On testing wharf 9.2 tweeters

[alexanish]

Friends,

I guess I am in trouble here. One of my Wharf 9.2's tweeters is not responding that great. When I try to increase the treble I could not make out whether the high frequencies are coming from the tweeter or speaker. In any conditions the other one in the pair is giving clearly distinguishable treble. I don't remember I have noticed this earlier. I might have thought that it's because of the content that I play. But today I could clearly make it differentiated and even with different content played over. But still I need to make sure the tweeter has some issue before taking it to dealer. Is there anyway I can test this and confirm on the failure?

Thanks!
Anish

Remove the jumbers from the HF and LF terminals and connect the cable from the amp only to the HF terminals. Do the same with both the speakers. Play some music which you know well and listen to the HF sound from both the speakers. If you can make out any differences in sound then take your speakers to the dealer for repair, if it is still under guarantee.
If the above doesn't help then it may be an issue of channel imbalance in your amp.

Thank God!!! It's working!!!

But still one of them is producing more sound over the other. My AVR has setting for volume level calibration on each speakers and they are set same for these two speakers. But no Tonal adjustment (Bass/Treble level) adjustment for individual speakers. You can only increase or decrease these on Fronts/Center/Surrounds. There is an equalizer setting as well but again only on channels - Fronts/Center/Surrounds.

Should I really take it to dealer? I am confused. I am afraid they may send it back to Wharf and during the back and forth travel the probable damage is terrifying me.

Probably you should connect it to any stereo amp (of your friend/foe/colleague) and get confirmed before taking it to the dealer.

I tried one more setup by switching left and right speakers. This time the low treble remain in the same channel, in other words the previously lower treble speaker is now giving better treble and other one low. I am partially relieved by the fact that the speakers doesn't have any problem. Now the probable culprit is AVR setting as you said. The Audessey might have done this setting. The reason I see is that the sitting position is more closer to one of the speakers than the other and the farthest one has more treble and volume level. I can change the volume level but no change to tone on individual speaker channels.
