I purchased a couple of 2nd hand RT3's a few days ago. When I connected them at home , I was a bit disappointed at first because they sounded somewhat stiff and lacking bass.
3 days later the sound got richer and deeper. Maybe because they were stored for a long time another break-in period was needed again.
Today - the 4th day, I listened to each speaker separately and found out that only one speaker has a deep bass and round sound.The other is lacking in bass and has a more rigid sound.
After removing the grills I noticed a slight difference in the glossiness of the membrane that surrounds the woofers. The stiff sounding speaker's membrane is a little more matte than the other's.
If this membrane was replaced (although the seller said these are the original speakers and no fixes were made) can this be the reason for the sound differences? Should I just wait longer for the 2nd speaker to break-in and "open up" its sound?
Thanks in advance for any advice or comment.
