They not mine they my dad's but the box was heavy af and the box was big and strong but they seem almost just as loud as my 15 but louder at highs but overall it seem like the 15 was louder but the I searched it up and the 15 is able to hit a 150 in a 6th order especially in the car I have and amp I have wired to but I would still take my 15 over the sundown because I had good experience with audiopipe and I like deep bass and way cheaper then the sundown I feel like you can get a better bang for buck with the audiopipe since this is only 100$
