Single 15" Custom Kerf Ported Subwoofer Box (HAND MADE IN THE USA)

Box is amazing. Designer and builder kept in contact with me to update and ask my opinion and goals. Couldn't be happier with it.

I order a single 15" heavy duty ported box tuned to 32 for a x15 sundown sub wooow I can't be more amazed of the quality the looks and finish and specially the sound of it daaaaam it takes up my expedition it sounds amazing I really recommend u guys in ordering one

I waited a cool 4 months for my box. Nonetheless just installed this in another vehicle than intended and with the same measurements i was BARELY able to squeeze it in which was amazing. I have a 15” Sundown X, inverted, tuned to 32-34 in a 4.5 cube box. I barely turn it up and all my trim wants to fly out. This is my 2nd box purchase and my first was made by keith so expectations were set. Whilst being another builder the attention to detail could have been better but stuff happens and i could not have done a better job myself. Definitely worth it without a question!

Took about 3 months from order date to arrival, but very well built & extremely efficient. I also chose mid duty as opposed to heavy duty when filling out the order form where you enter your dimensions etc. So I can't even imagine what type of tank they woulda built had i chose heavy duty, one of the box builders contacted me through text directly to ask if any of the dimensions were flexible as he was looking to get a little more internal volume out of the box build which eased my mind to know they were making sure I was happy with the finished product. If you're looking for quality & competence from a custom box builder, your on the right website

I'm very happy with the enclosure I ordered for a sundown xv2 15, its definitely heavy duty. It's built to last and it looks amazing. 100% satisfied and worth every penny!

Excellent communication got me exactly what I needed/wanted and more from this purchase. I wish they were hiring..

Definitely not prefab and built like a TANK...well built and plenty of communications with the builder Keith Sanders fast shipping and well protected. Definitely would recommend anyone wanting a custom box built for your Sub Specific Do it...

This box by far exceeded my expectations. Keith is the man. Definitely my go to shop for any and all car audio.

I love my D4S enclosure. Quality is spot on. Absolutely gorgeous finish with the high gloss. And not to mention the LED light in the plexi glass window really set it off. I highly recommend getting one of these, worth every penny.

Best box I have ever seen or owned. JP was extremely helpful throughout the whole process. This will be my first stop from now on for any car audio purchases.
