Further to my Mesa/Boogie 1x15 cab question thread..... I took the 15" speaker out of the cabinet and it did not say anything on it re:manufacturer/impedence etc. This is what was on it: Stamped on the magnet: 815 0593 508 Stamped on the cone: 79629 Sticker on side of speaker cone frame: 8999 Can anyone identify from these numbers the speaker manufacturer, the wattage and the impedence? Thank you in advance to anyone who can help!!
