The following can be done to test if speakers are wired identically and will cause no damage to your speakers.
You can easily check if it is your speakers that are miswired. Remove the grill cloth and disconnect the speaker cables from your amp. Take a freash 9 volt battery and touch the cable connected to the black or negative speaker terminal and make contact with the negative terminal on the battery. Now while watching the woofer touch the cable connected to the "positive" or red terminal of the speaker to the positive terminal of the battery. The woofer cone should move forward if wired in "correct" phase and will move backward if connected out of phase. The pther speaker should behave identically. Of course this won't help if the other are improperly wired out of phase in correctly relative to each other but at least will allow you to see if the speaker terminals are at least wired properly relative to the woofer.
