hello all. just purchased 4 wharfedale drivers off of ebay and one is distorted. noticed this one has failing driver foam glue. when pushing on speaker at one point, speaker stops outputting just about entirely. but when pushed from the inside, distortion goes away. speaker sounds blown out, but like mentioned before a quick push outward fixes it completely. could the glue failing on certain places be the culprit? pushing at 6oclock causes speaker to stop outputting, and glue can be seen dried and failed at the 12 o clock position. any help appreciated, thank you.
