This is hands down the best subwoofer box I have ever owned. It sounds great and the craftsmanship is excellent! Ted did a great job!

Had one custom built for a Sundown NSV5 12". Absolutely amazing. The whole process was amazing. From when you first put in the order, you will be in contact with Down4Sound making sure that everything is how you will like it. Dion was my builder, and he consistently sent me updates as he was building the enclosure so I could watch the ongoing process from across the country, and the finished product is just absolutely beautiful. I definitely was not expecting the customer service that I received. It was beyond Top Notch. Don't even get me started on the packaging. Hint: It's going to arrive safely to the destination without ANY damage what-so-ever. Order one, you'll see what I mean.

Very well built box. So happy that they made it out a better material than mfd. With the DC audio sub I have installed in it sounds... I cannot find a high enough prays for how it sounds and holds up. No rattling from the box or fluttering noises from the port. D4S is going to be my number one go to for sub boxes. Thanks for the amazing craftmanship.

I finally found time to get my speaker in my box & into my Jeep & I'm very satisfied with the strength & tuning that was put into my build.

The best enclosure I have ever own totally love the results would definitely be coming back for other one

Best customer service experience. I was able to get in contact with Keith quickly and easily. Sent me updates and was open to changes to the box.

The craftsmanship Keith puts into his boxes is astonishing. I have never seen something so beautiful. The quality of the box is beyond amazing. I ordered the Heavy Duty box version and this thing is solid and heavy. The packing that D4S did to protect the box in shipping is above and beyond. It was wrapped, cardboard boxed, Styrofoam noodled, wrapped again, and boxed another time and put on a pallet. I am beyond impressed at the time they took to protect the box in shipping. JP was helpful during the ordering process and when I had a question along the design process, Keith communicated very well when he was building the box, and Barbara was very helpful going back and forth with to make sure i got exactly what I wanted. I cant believe the overall work ethics that D4S has. Their customer support is top notch in today's age where its hard to find reputable businesses to do business with. I wouldn't hesitate for a second to work with D4S again.

I can’t say enough about the amazing craftsmanship and customer service. Keith kept me posted on the status of the build from start to finish. The shipping packaging was beyond belief. Customer service is always top notch with JP and Down4Sound but this experience blew me away. Buy your enclosure from D4S - is you will NOT be disappointed!
