Great experience from beginning to end

All I can say is wow this sub is a beast this is a very very impressive subwoofer power hungry but if you have the juice to push these subs you are in for a treat. 4 weeks in and the sub is just hitting it's peak sounds great I have had kicker jl w3 has both beat. You cannot go wrong here I'm only feeding it 1000 watts and handles all with no problem no distortion no clapping just very low clean sound

UNEXPECTED

I wasn't expecting this to be so clean and smooth reminds me of a beefed up polk mm sub. Its very clean and smooth on higher end freq which I really enjoy. It's power hungry you need atleast 1500 rms clean unclipped to really open these up. I thought id get away with 1000rms since the subs efficency is so high at almost 94db but it needs more so if you buy this trust a stranger at give it bare minimum 1500 true clean rms not a cheap hifonics 1500rms get a cea certified quality amplifier thats efficient and enjoy this clean low loud monster. This is not just a spl sub.
