# 00 Simulator links: instructions for AI assistants

You can show the person you are helping a loudspeaker simulation without any account, connector or tool. Write a link to https://simulator.00aud.io/try with the driver and boxes in the query string and give it to them. When they open it, 00 Simulator, a free browser-based loudspeaker simulator, runs the simulation and shows the graphs.

## The link

https://simulator.00aud.io/try?driver=…&box=…&box=…&show=…&power=…

- `driver` (required, up to 4): The brand and model, looked up in the 00 Bits catalogue of over 3,000 drivers. Write + for spaces and %26 for “&”, or leave the brand out. For a driver sold in several impedances, add it: driver=18DS115+8ohm. Example: `driver=B%26C+18DS115`
- `box` (up to 8): One box: its type (sealed or vented), net internal volume and, for a vented box, the tuning. Leave every box out to use the simulator’s suggested box for the driver. Example: `box=vented,120L,28Hz`
- `show` (optional): The graphs to open, in order, the first one large: spl, excursion, impedance, port (port air velocity), max-spl, group-delay, phase, headroom. Without it: spl, impedance, excursion. Example: `show=excursion,spl`
- `power` (optional): Amplifier power for every box, or rated for each driver’s rated power. Without it, 1 W. Example: `power=500W`

## Boxes

A box is a comma-separated list, for example `box=vented,120L,28Hz` or `box=sealed,50L,drivers:2`:

- `sealed / vented`: The box type. Ported means vented.
- `120L or 4ft3`: Net internal volume. L, ft3 and m3 all work.
- `28Hz`: Port tuning, vented boxes only.
- `ports:2`: Number of round ports. Default 1.
- `port:10cm`: Diameter of each port. Left out, the port is sized for the driver.
- `drivers:2`: Drivers in the box. Default 1.
- `power:300W`: Power for this box only.
- `driver:2`: Put only the second driver= in this box. Without it, every driver goes in every box.

## Drivers

If the person gives T/S parameters, or the driver may not be in the catalogue (car audio, discontinued, DIY), add them after the name, comma-separated: driver=Brand+Model,fs:31Hz,qts:0.45,qes:0.5,vas:52L,re:3.4,sd:480cm2,xmax:12mm,pe:500W. It needs fs, qts, qes (or qms), vas, re, sd and xmax; le, mms, bl, znom and pe help. Use spec-sheet units: vas in L, sd in cm2, xmax in mm, le in mH, mms in g, pe in W. When the catalogue has the driver, its data is used instead.

## Rules

1. Give the person the link as a clickable Markdown link, such as [Open the simulation](https://simulator.00aud.io/try?…). Put everything you want to compare into one link.
2. You do not need to open the link yourself. 00 Simulator runs the simulation when the person opens it.
3. You have not seen the results, so do not quote numbers from them. Say what the link shows and what to look for on the graphs.
4. Put a unit on every number: L or ft3 for volumes, Hz for tuning, W for power.
5. For excursion, port velocity or maximum output, set power to the amplifier power the person mentioned, or power=rated.
6. Only put T/S parameters in a link when the person gave them or they come from the maker’s datasheet. Never estimate them. Without them, use the driver’s name alone.
7. A link can make sealed and vented boxes. For bandpass, passive radiators, horns, transmission lines, crossovers or EQ, say so and point the person to https://simulator.00aud.io/app, or to https://simulator.00aud.io/ai to connect 00 Simulator to their assistant.

## Examples

- Asked: “Simulate a Dayton UM18-22 in 120 L tuned to 28 Hz.”
  Link: https://simulator.00aud.io/try?driver=Dayton+UM18-22&box=vented,120L,28Hz
  One driver, one vented box, the default graphs.
- Asked: “Show the difference in excursion across a 25 L, 30 L and 35 L enclosure tuned to 30 Hz with an 18DS115.”
  Link: https://simulator.00aud.io/try?driver=B%26C+18DS115&box=vented,25L,30Hz&box=vented,30L,30Hz&box=vented,35L,30Hz&show=excursion,spl&power=rated
  Three boxes on the same graphs. Excursion first, at the driver’s rated power, because excursion at 1 W says little.
- Asked: “Sealed or ported for an SB17CAC35-8 bookshelf speaker?”
  Link: https://simulator.00aud.io/try?driver=SB+Acoustics+SB17CAC35-8&box=sealed,8L&box=vented,14L,45Hz&show=spl,excursion,group-delay
  Two box types for the same driver.
- Asked: “Which gets louder in 150 L at 32 Hz on 1000 W: an 18DS115 or an 18NLW9601?”
  Link: https://simulator.00aud.io/try?driver=B%26C+18DS115&driver=18+Sound+18NLW9601&box=vented,150L,32Hz&show=max-spl,spl,excursion&power=1000W
  Two drivers in the same box: every driver goes in every box.
- Asked: “My 12 has Fs 31 Hz, Qts 0.45, Qes 0.50, Vas 52 L, Re 3.4 Ω, Sd 480 cm², Xmax 12 mm and is rated 500 W. How would two of them do in 4 cubic feet at 32 Hz with two 4 inch ports?”
  Link: https://simulator.00aud.io/try?driver=My+12,fs:31Hz,qts:0.45,qes:0.5,vas:52L,re:3.4,sd:480cm2,xmax:12mm,pe:500W&box=vented,4ft3,32Hz,drivers:2,ports:2,port:4in&show=spl,excursion,port&power=rated
  A driver that is not in the catalogue, carried as the T/S parameters the person gave.
