# Compare designs

> Compare enclosures in 00 Simulator: several designs on one graph, colours, eyes and solo, the Metrics and Compare tiles, and undo and saved versions.

Source: https://simulator.00aud.io/docs/guides/compare

Put the candidates in one workspace and every tile draws them together, one colour each. Duplicate, change one thing, then hide, solo and rank them until one wins.

## Several designs on one graph

Every visible enclosure in the workspace draws its own curve, in its own colour, on every tile. The quickest comparison is a copy with one thing changed. Here the vented example, and a copy made bigger and tuned lower:

_Figure: SPL of two vented boxes for the same driver at 200 W: the 55 L box tuned to 32 Hz, and a copy of 80 L tuned to 28 Hz that reaches lower._

Ciare 12.00SW at 200 W, half space, 1 m: Vented Example is 55 L tuned to 32 Hz, Vented Example 2 is 80 L tuned to 28 Hz. Simulated when this page was built.

| SPL (dB) | F3 | At 40 Hz |
| --- | --- | --- |
| Vented Example | 30.3 Hz | 110.1 dB |
| Vented Example 2 | 26.3 Hz | 108.5 dB |

1. **Duplicate.** Right-click the row › **Duplicate** (⌘D). The copy lands under the original as “Vented Example 2”, in a colour no other enclosure uses.
2. **Change one thing.** In the enclosure panel, set its **Volume** to 80 L and its **Tuning** to 28 Hz. The port length follows.
3. **Read the tiles.** The copy reaches lower (F3 26.3 Hz against 30.3 Hz) but its port runs faster: 33.4 m/s against 28.4 m/s on **Port Velocity**. That is the trade to judge.

- [Open the vented example](https://simulator.00aud.io/app?template=vented&power=200) at 200 W to try it.
- Hover a row in the list and its curve comes forward on every tile. Hover a hidden one and it shows dashed until you move on.
- For another type or driver, **Add new enclosure** at the foot of the list. Candidates for one question belong in one workspace, so they can share the graphs.

## Colours, eyes and solo

| To | Do this |
| --- | --- |
| Change a colour | Click the coloured dot on the row, or the swatch beside its name in a tile’s legend. |
| Take one off the graphs | Click its eye. It stays in the workspace and in the list. |
| Set several eyes at once | Press an eye and drag down the list: every row you pass takes the same state, as one undo step. |
| Show or hide them all | Click the count in the **Enclosures** header for **Show all**, **Hide all** and **Swap shown and hidden**. |
| Look at one alone | ⌥-click its eye (Alt-click on Windows and Linux), choose **Solo** from its menu, or press S with the list focused. ⌥⌘-click (Alt+Ctrl-click) adds another to the solo. |
| End a solo | Click the **SOLO** chip in the list header, or press Esc in the list. The eyes are as you left them. |
| Pick one to edit | Click its row, or its name in any tile’s legend. |

> **Name candidates in parts** Names split by ` | `, such as `Vented Example | 55 L` and `Vented Example | 80 L`, group into a family when the rows sit together: one label, with an eye and a fold for the lot. Copies with different drivers can be renamed that way in one go with **Name by driver** on the row menu.

Most of this has a key when the list has focus: [Keyboard shortcuts](https://simulator.00aud.io/docs/guides/shortcuts).

## Rank them with the Metrics tile

**Metrics**, under **Info** in **Add tile**, ranks every visible enclosure on one number and marks the best. Choose the number from its menu; some take a frequency or a band. A chip says which way wins, **Higher wins** or **Lower wins**, and each other row shows how far behind it is.

The Metrics tile’s own sums on the two runs above, at its default frequency and bands.

| Metric | Wins | Vented Example | Vented Example 2 |
| --- | --- | --- | --- |
| F3 (−3 dB) | Lower | 30.3 Hz · +4.0 Hz | 26.3 Hz · best |
| F10 (−10 dB) | Lower | 24.9 Hz · +2.8 Hz | 22.1 Hz · best |
| SPL at frequency, 40 Hz | Higher | 110.1 dB · best | 108.5 dB · −1.6 dB |
| Peak Xmax use over band, 20–80 Hz | Lower | 93% · +2% | 91% · best |
| Peak port velocity over band, 20–80 Hz | Lower | 28.4 m/s · best | 33.4 m/s · +5.0 m/s |

It offers F3 (−3 dB), F10 (−10 dB), SPL at frequency, Max SPL at frequency, Group delay at frequency, Average SPL over band, Peak Xmax use over band, Peak port velocity over band, Peak PR excursion over band, Minimum impedance over band and First port resonance. The tile’s own page explains each: [Metrics](https://simulator.00aud.io/docs/reference/tiles/metrics).

## Two quantities at once: the Compare tile

**Compare**, under **Graphs · advanced** in **Add tile**, draws two quantities for every visible enclosure on one frequency axis: the **Left axis** one solid and the **Right axis** one dashed, both in the enclosure’s colour. It starts on Excursion and Group Delay. Choose others in its settings, or one of its **Presets**:

- **Excursion + Group Delay**
- **SPL + Amplifier Load**
- **Impedance + Electrical Phase**
- **SPL + Excursion**
- **Max SPL + Limit Excursion**
- **Port Velocity + Excursion**

Use it to see why a design wins: where the excursion peaks against the group delay, or where the port speeds up against the cone. More on the tile: [Compare](https://simulator.00aud.io/docs/reference/tiles/compare).

## Try things and go back

- **Undo** and **Redo** (⌘/Ctrl+Z and ⌘/Ctrl+Shift+Z) step through your edits, tile moves included. The arrow between them lists the last six steps: choose one to undo back to before it.
- **History and saved versions…**, at the foot of that list, opens **Workspace history**. **This session** lists every step since you opened the workspace; signed in, **Saved versions** keeps a numbered version of each save to preview and restore.
- Signed in, a row’s menu has **Move to workspace** and **Copy to workspace**, to take a candidate to another workspace, or keep a finished one apart.
- A workspace your AI assistant starts for a new question is a draft. Drafts wait at the top of your library for **Keep**, and are archived after 7 days if nobody keeps them.

All of it, for guests and accounts: [Workspaces and accounts](https://simulator.00aud.io/docs/guides/workspaces).

## Ask your AI

**Ask your AI**

Your assistant adds the candidates to the same workspace, so they appear on your graphs next to the original.

> Using 00 Simulator, add two alternatives to the vented box in my open workspace, one bigger and tuned lower and one with twice the port area, then compare all three at their set power: F3, peak excursion against Xmax and peak port velocity.
