decent box

The following review is for 1SV12G, which is a part of the bundle you are viewing.

i bought this box for the newest alpine type r.... lets say it sounded decent but not good enough for me, i have had many sound systems and this didnt sound so good with the type r..... if your decide to get a type r id go with a 3.0 cu ft box tuned 32-38hrtz for the best deep loud sound quality

Great Solid Box

The following review is for 1SV12G, which is a part of the bundle you are viewing.

This box is built very well. It's perfectly tuned for the Alpine SWR-1243D Type-R that I also got from Sonic Electronix. The SPL of this combo is ridiculous in the trunk of my '09 Civic Si Sedan, and it leaves more than 3/4" of my trunk space left for other junk. Definitely recommend. With a set of banana plugs also ordered, I still only spent less than $225 which includes the price of shipping for these three items. Speaking of which, I ordered in the early hours of Tuesday (switching over from Monday) and I got the these three items delivered to my door by 11AM Wednesday! There's no way you can find a better deal than that! Now all I need for this combo is some serious Dynamat to keep everything from rattling apart.

Great Box!

The following review is for 1SV12G, which is a part of the bundle you are viewing.

This is a nice box for the price. I normally build my own boxes but I didn't have much extra time and it is too cold out to build one anyways, so I bought this one and I'm sure glad I did. Realistically to buy a sheet of MDF, spray adhesive, bottle of wood glue, nails, and carpet costs about the same as this box and it is already made. Sure it is prefab, but its a very good prefab enclosure. This is real 3/4 inch mdf and the port is tuned pretty low too. I would guess like 34-36 Hz or so. Very solid construction and rounded off port on the inside. Carpet looks great. Terminals are nice too, although they are plastic fasteners, they will hold up just fine. I have a Phoenix Gold rsdc in this box and it slams! I can feel the bass pounding my chest. If you want a nice loud box, this is the box you want. Exceeded my expectations by far!

Bela Sub Box 1st 12 box

The following review is for 1SV12G, which is a part of the bundle you are viewing.

The box is built great, sturdy. I didn't pay attention to the overall dimensions the box is bigger than your average 12" box.
So if your looking to put this box in your car make sure you pay attention to the dimensions. But if your building a subwoofer for home or small club this box will do the job.

Not correct box volume

The following review is for 1SV12G, which is a part of the bundle you are viewing.

The box is advertised to have 1.8 cubic feet of volume. It's not, the actual volume when taking into the account of the wood thickness and the ports is 1.3 cubic foot. Plus when you add a sub in it that will also take up some volume so you can count on 1.1-1.25 cubic feet with a sub mounted. The 1.8 cubic foot might be true if their talking about total volume of the outside but that is compleatly irrelevant. The only volume that is important is the inside of the box. And yes the difference between 1.8 and 1.3 is a lot and will make a difference

This subwoofer box is great and produces a lot of loud bass. However it is huge so make sure you have enough room.

Sick box.

The following review is for 1SV12G, which is a part of the bundle you are viewing.

It's pretty massive. Carpet matched my trunk which is a win. Screw terminals are not the best but they work.
