On some s**t Jehovah ain’t even witness yet.

As far as I know, first 4th order underseat for full size 10”s I’ve seen. Seen it done with shallows before, 6.5”s and 8”s but that’s easy lol, but not full size 7”+ deep 10”s. Please, correct me if I’m wrong 🤜🏽🤛🏽

Anyways,

Again, this enclosure is SEALED, not ported.

They are in 1 cube per sub, SEALED, go look up Kickers SEALED enclosure specs before you try and tell me they aren’t in the correct airspace. 🤓

Also, this track plays from the mid 20s up to 50hz, it smacks every note, so I don’t wanna hear s**t about it ain’t got any low end either😂🗣️

How many of yall shops have told people that BIG 12”s aren’t possible? You lied 🤣🫵🏼

Thanks for keeping me busy. Forever building what people claim ain’t possible.

5.7 net, tuned to 28hz, she jams 🔊
