This has got to be one of the best built enclosures I have gotten. The whole experience was awesome! Received updating photos of the progression of the build and awesome communication with that actually craftsman on my project. Even had off topic conversation just in car audio in general and always got fast response.

From start to finish Barbara and Keith were phenomenal! Barbara verified all the specs and kept me in the loop prior to the build, then Keith knocked it out of the part. Keith sent pictures of the build from start to finish and contacted me to ensure all of the details. These guys run a tight ship and put out nothing but quality. D4S is hands down the best in the business. Don’t hesitate to buy, if you want outstanding quality and a service after the sale you will not find better.

Johnathan was awesome on ordering process called me on the phone to verify all details, Barbara took care of the box design texting me with specs and a detailed design, and finally Keith Sanders knocked it out of the park sending me pictures during the build process! Great experience throughout the whole process, about ready to order another box. A NSV4-10D2 can't wait for the next process with this awesome shop!!

These boxes are definitely some next level stuff. I had several questions about the box as there are many options available for the build. Jp was there to help me & I have to say that down for sound difference is no joke. These dudes are definitely the best in the business.

Nicest boxes I've ever seen, thanks jp for the D4S experience!!
