Because the sub you posted is a joke... Look at the magnet, and the cone is made from paper... So is the FI, but the FI is treated...
I hate how instead of answering my question people try to change my mind for me...
Size isn't everything, I am will to bet on the 300rms you plan on using the sub I posted will get lower and louder than the Fi, Why would you buy something that you never plan on powering properly. if you want to spend extra and not get the potential out of the sub be my guest, and about the paper cone, why does that matter from what I deducted from you post this isn't a patio system.
Edit: So after reading you post history I see you are 12, I suppose you are also that pro box builder that was on here as well, either way it's gonna quite a few years worth of grandma's christmas checks before you get one sub, so post back then
Dude, please don't be a faggot. Honestly, why do people play the age card. It just makes you look like a little fuck. And just so you know, both my grandma's are fucking dead! Happy?!
My parents came to me and asked me to build a home theater system for the movie room in the new house... So fuck off, and don't be a faggot who uses the age card...
and fyi, basically everyones grandparents are dead (that are on this forum), thats life and you deal with it, you dont flame over the internet,
