You already know it's excellent

The following review is for R2-W12D4, which is a part of the bundle you are viewing.

Great product but I still have to gripe about the fact that you have to purchase the grille separately. It's like, c'mon. I just dropped $400 on this sub and you guys couldn't throw a $3.00 (manufacturing cost) piece of plastic in the box with it to help me protect it? Instead, they want another $35 (before taxes and shipping) from me. It's a bad taste in my mouth toward the company. And put a freaking sticker or something in the box, too. Everyone loves a little swag for their toolbox or whatever. Likely one of the last Alpine purchases I'll be making after seeing that their loyalty is more towards the shareholders than the music!

Bassssssss

The following review is for R2-W12D4, which is a part of the bundle you are viewing.

This is absolutely the subwoofer to have. I've had kicker, Rockford fosgate, pioneer, and skar in the past but this subwoofer is solid as far as the name brand subwoofer go.
