So somehow I've managed to blow both speakers on my SWR 12-Pack (2x12 8 ohm) cabinet. They're both torn on the outside edge of the cone where the paper meets the rubber section. Is this a warranty thing or do I need to find replacement drivers? I'm waiting on a response from SWR. What kind of drivers could I replace these with? I'm not entirely sure how this happened. I use this cabinet with a 4x10 8 ohm ampeg cabinet daisy chained to put a 4 ohm load on my vintage SVT. The SWR cab is rated for 400 watts and the ampeg 300 watts. I shouldn't have been able to blow it theoretically.
