AI Powered Subwoofer Enclosure Designer BoomBoomBoxBuilder

[mattypeezy79]

Hi everyone, I made a custom GPT on OpenAI, just search for BoomBoomBoxBuilder,. You can ask it questions or you can have it guide you step by step through the entire process.  It doesn't matter if you've never designed an enclosure before or if you've designed 100. It will also provide detailed graphs, charts, simulations, 3D rendering, Cut Sheet and much more. Just ask.  It uses WinISD, REW and more to help design the most optimal enclosure possible for your build. Please try out and leave me a review. This is my first try at ever doing something like this so please let me know how it works out for you and I am open to suggestions on how I can make it better. Here is a direct link to it https://chatgpt.com/g/g-6HLhjOa1w-boomboomboxbuilder-ai-subwoofer-enclosure-designer Thank you. [email protected]

False claim REW has no place in box modeling or layout at all, is strictly for measuring real world data.

Neat idea

It's been my experience that LLMs really struggle with simulating data like that though. A quick primer if you don't know how they work:
Using a fuckton of math. Like, multi-thousand dimensional matrix multiplication - It completes an interaction based on a most-likely-word to complete a given chain. So for example, if I asked you to complete the sentence: "I walked to"

You might say 'the store' or 'my friends house' because those are likely endings. But you probably wouldn't say something like 'cooked for 1 hour' or 'because it knows where it isn't' because neither of those would make sense - it's not a language pattern the LLM found in its data.

With that context in mind, it doesn't have the ability to analyze information. Only regurgitate language patterns and, at times, theorize about new things (independent of if that's real or not). That's usually best left to other tools.

LLM is great for interfacing with the user, but you'll probably need a dedicated neural network or perhaps even a deep learning model for handling the actual box calculations. That would need to be spit into modeling software to evaluate, given a p/f or ranking or some sort, checked against user constraints, then repeated again until it narrows in on a design.

Regardless - I vibe with the idea here. It would be pretty neat to get a functional design tool. Especially for new-user type stuff where it can help with all the 'gotchas' of building a box. Like port aspect ratios, high/low pressure sections in the box, the somewhat 'fuzzy logic' of power, net volume, port area, and tuning, etc etc...

Nonetheless, this was my user interaction if you wanted to gauge how the thing behaves:

 

I have a sundown sa12 on 1200w. I want it tuned to 29hz. My max dimensions are 24x24x24

 

To design a subwoofer enclosure for your Sundown SA-12 with 1200W RMS power, tuned to 29 Hz, within the maximum dimensions of 24x24x24 inches, we need to determine the optimal enclosure type and dimensions. We'll use the typical parameters for a ported (bass reflex) enclosure since it's common for achieving good low-frequency extension and output.

### Subwoofer Parameters (Sundown SA-12)
- **Subwoofer Size**: 12 inches
- **RMS Power**: 1200W
- **Fs (Resonant Frequency)**: 33.0 Hz
- **Qts (Total Q Factor)**: 0.46
- **Vas (Equivalent Compliance Volume)**: 21.5 liters (0.76 cu ft)
- **Xmax (Maximum Linear Excursion)**: 19 mm
- **Recommended Enclosure Volume**: 2.0-2.5 cu ft for ported box

### Step-by-Step Design

1. **Calculate Internal Volume**:
   Given your maximum dimensions (24x24x24 inches), the internal volume can be calculated considering the thickness of the material (typically 0.75 inches for MDF).

   - External dimensions: 24" x 24" x 24"
   - Internal dimensions: \( (24 - 2 \times 0.75) = 22.5 \) inches (for each side)
   - Internal volume: \( 22.5 \times 22.5 \times 22.5 = 11392.875 \) cubic inches
   - Convert to cubic feet: \( 11392.875 / 1728 \approx 6.6 \) cubic feet

   However, this volume includes the space taken up by the subwoofer and the port.

2. **Adjust for Subwoofer and Port Volume**:
   - Subwoofer displacement: approximately 0.1-0.15 cu ft
   - Port displacement: depends on the design, but let's approximate it at 0.2 cu ft

   Effective internal volume: \( 6.6 - 0.15 - 0.2 = 6.25 \) cubic feet

3. **Target Volume and Tuning Frequency**:
   - Recommended volume for a ported enclosure: 2.0-2.5 cu ft
   - Let's choose a target volume: 2.5 cu ft
   - Tuning frequency: 29 Hz

4. **Calculate Port Dimensions**:
   Use a port calculator or the following formula:
   
   \[
   L = \frac{{(23562.5 \cdot D^2)}}{{(Vb \cdot Fb^2)}} - 0.823 \cdot D
   \]
   
   Where:
   - \( L \) = Port length (in inches)
   - \( D \) = Port diameter (in inches)
   - \( Vb \) = Box volume (in cubic inches)
   - \( Fb \) = Tuning frequency (in Hz)

   For a slot port:
   - Assume a port area of 16 square inches (4" x 4" port).
   - Port length \( L \) can be calculated iteratively or using online calculators.

### Example Calculation:
Using a port calculator:
- Box Volume (Vb): 2.5 cu ft = 4320 cubic inches
- Tuning Frequency (Fb): 29 Hz
- Port Area: 16 square inches

Approximate Port Length (using a port calculator):
- Port Length: ~20 inches

### Final Design Dimensions:
- Internal box dimensions: approximately 18" x 18" x 22" (accounting for bracing and subwoofer displacement)
- Port dimensions: 4" x 4" x 20"

### Blueprint:
1. **Front View**:
   - Subwoofer centered
   - Port on one side

2. **Top View**:
   - Subwoofer cutout
   - Port extending along one side

3. **Side View**:
   - Box height: 18 inches
   - Port extending back 20 inches

### Materials:
- **MDF or Plywood**: 0.75 inches thick
- **Bracing**: Recommended for structural integrity
- **Sealant**: Ensure airtight construction

### Tools:
- BassBox Pro
- SketchUp/CAD for visualization
- Measurement tools for precision
