Nice box, but?

The following review is for NE122S, which is a part of the bundle you are viewing.

This box sounds awesome with my NVX subwoofers. I had to reflue the poly inside the box because not enough glue from production. Also, the terminals are cheap. Replacement is recommended. All that aside this box hits hard with the optimal manufacturers recommended air space. I replaced some CT Sounds 1250 rms Stratos off a 2000.1D CT amps. They couldn't even keep up, even with thier amps.alway bottomed out. I put the NVX3s in A NVX box with the specs. Night and DAY. These subwoofers just my be better than the JL W7. By the way the CT Sounds are in a custom box .

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.
