Hello! I recently purchased a pair of 2405, i check visual the diaphragms and the dcr of each driver. The dcr in both diaphragm was the same and the diaphragms visual looks
In ok condition. After taking them home i hooked them on my system and i realize that the one plays lower than the other and also with less detail. The diaphragms looks original and the one driver with the issue looks like never been opened before. Whats the problem could be?
