    This is the nicest box I’ve ever ordered! It sounds better and hits the lows! I reached out asking for custom port tuning and cutout diameter and he hooked it up! It arrived quicker than I expected in perfect condition! Packaged up really well so no damage upon arrival. It’s tuned exactly to where we talked about and the cutout diameter is perfect. I’m super happy with my purchase! It looks so nice and for the price you can’t beat it! Wayyy better then pre fab boxes lol Thank you!!

    Wow is all that I can say….. the quality and craftsmanship for the price is unmatched!! I ended up receiving my box 2 weeks earlier than the posting listed. They went above and beyond with packaging to ensure absolutely nothing could go wrong during shipping. I highly recommend anyone in the market for an enclosure to look no further than here!

    This is the nicest box I have owned and I have owned several gately boxes as well as other custom boxes. Tyler did a great job not only taking my special request for a lower tuning for my 12” Sundown Audio Nightshade v6, but recommending an upgrade to birch. The box arrived extremely well packaged with absolutely no damage. You are not going to find a better box at this price point period. Very high quality box ! I will recommend all my friends to use concept enclosures for their box needs.
