I'm doing free box designs now, for sealed and regular ported boxes (includes aeroports). I've done a few for people on here and other places already. -->If you want to be a guinea pig, I will try a 4th or 6th order, but definitely no promises on those designs. If I get a few people to give me a chance on these designs, I could probably get good at them.

Let me state a few things:

1) I don't build, I design. Don't PM me asking about building or shipping you a box.

2) If your box won't fit, I'll let you know. If you want to stuff it in there, I can try my best, but I won't promise anything.

3) I will make recommendations as far as sub and port location, but ultimately it is up to you.

4) I will make recommendations as to how many cubic and what tuning you should use.

5) I contact you through either PM or email, which ever you prefer.

6) I usually do music/daily boxes. I don't like to design strictly SPL/fart boxes, but I might be willing to make an exception depending on your situation.

7) I will do a SPL or SQ oriented daily box, but I usually do lower tuned boxes.

8) There is no sub I won't do a design for, as long as it's meant to be in a sealed or ported enclosure. I will NOT check out other box designs.

9) When it comes to sub manufacturers that recommend higher tuned boxes, I usually like to tune slightly lower. (Especially when it comes to companies like Digital Designs and Audioque

10)If you have any recommendations when it comes to how I present myself to you, please tell me. Also, tell me if you need me to draw my design in a 3D version. It'll take longer, and please only ask if it's absolutely necessary.

11) This is a long shot, but I'd appreciate any donations for doing box designs. I don't care if it's only $1, it still helps.

12) If you get a design from me, please tell your friends or other people on other forums. I'll do designs for anyone. I don't mind if you have my email and give it to someone who needs a design.

13) If you need general recommendations for what sub and/or amp to run for your application, I can help. I don't know every brand out there, but if you're completely lost I can guide you in the right direction.

14) I will try to answer box requests as rapidly as I can. The better contact you keep with me, the quicker I will have your box designed.

15) Most importantly (at least to me) is that each box I design is custom made. I start from scratch, no pre-designed enclosures. Period.

IMPORTANT: Make sure you send me the t/s parameters & specs, dimensions, and what kind of sound you are looking for. If I agree to do a SPL design, the resonance frequency of your vehicle would be very helpful.

Me:
If you want to know why I do this, it's because I enjoy designing boxes and helping fellow car audio fans. I remember when I was new to this trying to make due with what I had. I started this mainly for the people new to the car audio scene, but I'm willing to help anyone. Each box design is it's own unique challenge, and there is never a boring box. It's fun trying to make a sub sound beautiful and get loud. I don't take shortcuts, and I will design that box to the absolute best of my capability. Any questions, don't hesitate to ask. If you have doubts or any conflicts with my design, I will attempt to explain myself and change what needs to be changed. Just let me know how I can help you

***Edit: I can get a box built for you if you are local. Just let me know.
