How to checked damaged speakers.

[Ben10]

Hi Friends,

I am using Edifier s550 5.1 multimedia speakers.Initially they were connected to my PC .For the past 2 months they have been connected with my amplifier NADT752 , initially they sounded brilliant and i could easily feel difference in sound quality (i.e with and without amplifier) .
but now after 2 months of use i can feel ( or better hear) that there is an considerable degradation in there sound quality.The sound has become harsh , some frequencies are missing and some are very low.The sound is just un-audible ( for average audiophile ears). I am sure that speakers might have damaged due to amp output but how can i make it sure.
The speakers are still under warranty and now i have placed the amp in different room and connected them back through Sub-woofer ( in built amp)

Now the Big question is " how can i convince the service guy from company that sound is un-audible and speakers might have damaged/degraded over a period of 6-7 months".

I need suggestion from all as i would be scheduling the visit by service guy for Saturday.

ideally they should not have been connected through amp as the sub unit has a amp itself to drive the speakers at proper ratio..

but now as you feel the damage.. call the service guy and tell that these speaker shut down randomly.. no fixed pattern and sometimes work for a day and sometimes again n again and they have started souding harsh..


you will have a point to get it replaced.. else just by sound degradation atleast in india forget about the replacement...

just tell some kind of issue that they will be forced to replace and add your sound issue that sound output is not constant and not clear at times.. ask them to compare with the new one.. and you will be all set...


just a trick....
