Read the comments and still made the mistake of buying this POS, when it arrived there was almost no protection, scratches and dings all over the box, built poorly almost fell apart as I picked it up to bring inside, looked inside the box, no caulking anywhere and the port baffle was t even touching the top and bottom of box. Do not waste your time thinking that you can make it better, the only thing it made was good firewood

Figured this was a logical upgrade from my prefab Skar SDR box.. in every sense, I was wrong. Box is absolutely massive, which would be great if it did anything other than take up space. Let’s start with packaging.. single layer of thin cardboard. That’s it. No double box.. He’ll not even a trash bag to waterproof it. Shredded 2x in shipping and was taped together in seemingly every terminal from the tracking info lol. Next, build quality. It’s cheap mdf. We all saw from the listing sure. But only baffle/top/bottom.. sides are like 1/4”. “Sealed air tight”.. where? I think the whole box has one complete seal from corner to corner. Everywhere else is an inch or two here and there. I could’ve done a better job in the dark with scissors for hands. The port is just a scrap piece of half inch mdf tossed in and held there with what seems to be just prayers.. it rattles. A lot. Not just the port wall.. Everywhere. The terminal cup.. is sad. Very sad. “Spring push terminals”. Nope. You get the garbage screw down ones that loosen if you even talk too loud. And on the inside, the terminals get worse.. Thing of them as thick gold colored tin foil that you’re hooking leads to. Pathetic truly. And the driver cutout is definitely large. Too large for some. I didn’t have that problem though, as mine is girthier than most apparently. Finally, if you overlook all of it flaws.. and lower your jewel into it and connect all the proper lightning hoses to it, you’ll realize that it sounds horrendous. Not just the rattling of every panel. But the tuning.. it’s a joke. Like was no engineering done? “We make box. We cut round hole in box. We put more hole here. But square. Lets the whoosh out. Make go boom boom boom”… All jokes aside, The carpet guy.. make that man Chief Executive Officer asap. He seems to be the only employee without a lower than room temp IQ. Those carpet seams.. chefs kiss. Masterful.TLDR: buy something else.. the Skar prefab SDR18 box is cheap, half the size, better terminals, better tuning, and is usually everywhere on marketplace for less than a Benny.

Would like to give this 5 stars, but a couple details keep me in particular from giving it 5 stars. The problem many reviewers have with the hole size was not an issue for me. An Re Audio MX18 fits perfectly without any modification to the hole. With that said If you have anything but an Re MX18 or any other larger than normal subwoofer you will have issues mounting your woofer as the hole will be too large. Unfortunately the Re needs a much more port area than this box offers, a little over double to be exact, so extensive modifications need to be done to get the sub to perform properly. Also the 2 smaller sides(the port side and the opposite side)are 3/4 mdf. I bought this box to hopefully perform some small mods as I typically do with a prefab, but this one will require more than some small mods. Build quality is good as it is mostly 1"mdf, but needs to be much better for my application. Would recommend for any low line 18, but keep in mind the hole will be too big for a low line 18.

I received a box damaged with a hole cut too big the first time I ordered. I sent in for a return and received another damaged box with the same problem of the damage of the carpet and the whole was too big again. That process took 60 days and now I'm waiting seven days for my refund and have to take both boxes to the dump because they are damaged and defective..I highly recommend it to not buy this product and do not waste your time. I thought I would buy the box to save a little cash from having one custom built but it just ended up being a big hassle!! Furthermore the port design is poor and the box is not very solid. It would need screwed together and reinforced if it has a speaker of any significant value in it, or it will be blown apart in time..too many pictures to post all the damages..

Carpet was a little beat up but thats to be expected honestly with a box that wieghs 100 lbs.the cutout for the speaker is a little big like others have mentioned for a 18inch. Its more like a 19 or 20inch cut out but it worked out ok for me with my re sx18 mounted inverted plenty of room for the suround to fit inside the rim of the cut out was right next the mounting holes but since the wood is 1 inch thick i predrilled the holes at a 45 degree angle then bought some metal fasteners at home depot. Even though im not using the terminal cups "sub is inverted" they are pretty nice some of the best ive seen on a prefab box. Update: after 2 weeks of banging the port cracked in the middle had to put some wood inside the port to brace it.
