Hello all, i'm here to figure out the differences between these 4 (sub)woofers, and this seemed the best place to ask. What i will be using the driver for is mainly music and they will be crossed over at around 50~60hz, and i wont need extension past 25hz. A few differences i know is the 2245 uses a foam surround which has less excursion, but if someone can help me find the best woofer for my application i would be very happy.
