REW Integration Setup
REW (Room EQ Wizard) is free professional audio measurement software. When connected, Tuning Labs replaces its built-in mic RTA with REW's calibrated, high-resolution frequency data. REW must be installed and running on this computer — it cannot run on a phone or tablet.
- Windows 7+, macOS 10.13+, or Linux — any modern computer
- Java is bundled with REW — no separate install needed
- REW version V5.40 or newer (the REST API was added in V5.40)
- A measurement microphone is recommended but not required (laptop mic works for basic use)
Step-by-step setup
-
Download and install REW (free)
Visit the official site, download for your OS, and run the installer.
⬇ Download REW (free) roomeqwizard.com — Windows / Mac / Linux -
Open REW and enable the REST API
The API lets Tuning Labs read REW's live data.REW menu bar → Preferences → API tab
✓ Check "Enable REST API"
Port: 4735 (leave as default)
Click OKAfter enabling, REW will show "REST API enabled on port 4735" in its status bar.
-
Configure REW's RTA settings for live data
These settings ensure Tuning Labs receives real-time frequency data instead of heavily averaged (static) data.In REW, open the RTA window → click the ⚙ gear icon (or right-click the RTA graph) to open RTA settings:
Mode: RTA 1/48 octave (or 1/24, 1/12, 1/6 — higher = smoother bars) Averages: None (real-time, no averaging — best for live tuning) FFT Length: 64k (best frequency resolution) Max Overlap: 93.75% (fastest update rate) Important: Do not use "Forever" averaging — it accumulates all frames since RTA start, making the data appear frozen after a few seconds. Use None for fully real-time data, or Exponential (4–8 averages) if you want light smoothing.
-
Run the Tuning Labs REW Bridge (required — bridges REW to your browser)
Browsers block direct localhost connections (CORS policy). The bridge is a tiny Node.js relay — no npm install needed — that runs in a terminal window on this computer and forwards REW data to Tuning Labs in your browser.Option A — One-click launcher (Windows, easiest):
1. Download: ⬇ Start-REW-Bridge.ps1
2. Right-click the file → Run with PowerShell
3. Keep the window open while tuning
Option B — Manual (any OS):
1. Install Node.js (free, LTS recommended)
2. Download: ⬇ rew-bridge.js
3. Open a terminal in the same folder and run: node rew-bridge.js
4. Keep the window open — it should say "Tuning Labs REW Bridge running"The bridge listens on port 7735 and relays to REW on port 4735. If port 7735 is busy it will auto-find a free port (7736–7739) and tell you which one.
-
Connect Tuning Labs to REW
Switch the RTA source to REW on either the main RTA page or the Full-screen RTA page.On the RTA / Live Tuning page (or RTA – Full Screen):
→ Click "REW Live Data" in the RTA Source bar
→ Click "Connect"
→ The dot turns ● green and shows "Connected" with the REW version
→ Select a measurement from the dropdown → live frequency data feeds the RTA canvas
Tip: REW provides oscilloscope, waterfall, THD, and level meter views in the application itself.
Troubleshooting: If it says "Not found" — make sure REW is open, the API is enabled (step 2), and the bridge window is running (step 3). Press F12 → Console for detailed connection logs.

User Tools & System Calculators
These tools help you size power wire and fuses, estimate port lengths, and calculate box volume. All results are starting-point estimates — always verify critical measurements against manufacturer specs or a dedicated design tool before cutting wood or pulling wire.
1. Amplifier Gain — AC Voltage Method
Set amplifier gain with a multimeter on the speaker output terminals — never by ear. Works best with a sine-wave test tone and all EQ/tone controls set completely flat.
- Turn all amp EQ, bass boost, and loudness controls off. Set the head unit EQ completely flat.
- Disconnect speakers from the amp channel you are setting (or unplug the sub). Do not run the amp unloaded — reconnect after adjusting.
- Play a clean sine-wave test tone at the target frequency (40 Hz for sub, 1 kHz for mids, 10 kHz for highs).
- Raise the head unit to the loudest realistic volume you will ever use — typically 75–80% of maximum before you hear distortion.
- Set your DMM to AC volts. Probe the amp speaker output terminals.
- Slowly raise the gain knob until the measured voltage matches the target below. Stop there.
Formula: V = √(P × R) — P is RMS watts, R is impedance in ohms. Example: 150 W into 4 Ω → √(150 × 4) = √600 ≈ 24.49 V AC. Always use the amp's rated RMS power at the rated impedance, not peak power.
2. Speaker Wiring — Parallel, Series, Series‑Parallel
How total impedance changes when multiple speakers share one amp channel.
- Parallel — positives tied together, negatives tied together. Impedance drops. Two 4 Ω speakers in parallel = 2 Ω. Formula: Z = (Z₁ × Z₂) / (Z₁ + Z₂).
- Series — daisy-chain: amp+ → spk1+ → spk1− → spk2+ → spk2− → amp−. Impedance rises. Two 4 Ω speakers in series = 8 Ω. Formula: Z = Z₁ + Z₂.
- Series‑parallel — wire pairs in series, then put those pairs in parallel. Four 4 Ω subs wired series-parallel = 4 Ω total (pair = 8 Ω; two 8 Ω pairs in parallel = 4 Ω).
Important: never run an amp below its minimum stable impedance. Most car audio amps are rated for 2 Ω stereo or 4 Ω bridged mono. Check your amp spec sheet first.
3. Power Wire Gauge
Enter total combined RMS output of all amplifiers, system voltage, and one-way run length for the main battery cable.
Method: Estimates current assuming 50% Class-AB efficiency (worst-case conservative), adds 20% safety margin, then bumps for longer runs to limit voltage drop. Always fuse the main power cable within 18 inches of the battery.
4. Main Fuse Size
The main fuse protects the wire, not the amplifier. Size the fuse to match the wire's ampacity, not the amp's power rating.
Formula: I = Watts ÷ Voltage, then rounded up to the nearest standard ANL/AGU fuse with a 25% headroom margin. This is the minimum recommended fuse — do not use a smaller rating. Cross-check against your chosen wire gauge: e.g., 4 AWG copper ≈ 100 A maximum.
5. Ported Box — Port Length Estimator
Estimates the starting-point port length for a vented subwoofer enclosure based on the Helmholtz resonator formula. Enter net box volume (internal volume after bracing and driver displacement), desired tuning frequency, port shape, count, and dimensions.
Formula: L = (S × c²) / (V × (2πFb)²) − 0.732√S where S = total port area (in²), c = 13,584 in/s (speed of sound at ~77 °F), V = box volume (in³), Fb = tuning frequency (Hz). The −0.732√S term corrects for air-mass end effects at the port opening(s). Cut the port 1–2 in long and trim to verify tuning before finalizing.
6. Water Displacement → Internal Air Space
Fill a bag or enclosure with water, measure how many gallons it holds, and convert to cubic feet of internal air space. Ideal for saddlebags and any shape too irregular to measure directly.
Formula: ft³ = gallons × 0.133681 (1 US gallon = 0.133681 ft³). Subtract woofer magnet/basket and port displacement from this total to get usable net volume.
7. Simple Rectangular Box Volume
Enter the three inside dimensions of a rectangular enclosure in inches. The result is gross interior volume — subtract woofer, port, and brace displacement to get net volume.
Formula: Volume (in³) = H × D × W; Volume (ft³) = in³ ÷ 1728.
8. Irregular / Saddlebag-Style Box Volume
For tapered or saddlebag-shaped enclosures. Enter six inside measurements in inches: height at the front face and at the rear/tail, the front-to-back depth measured along the top and along the bottom of the front face, and the total length measured across the top and across the bottom. The calculator averages each pair to approximate the equivalent rectangular volume.
Method: V = avgH × avgD × avgL ÷ 1728 (averaged dimensions, rectangular equivalent). For very irregular shapes, divide the enclosure into simpler sections, calculate each separately, and sum the results.
9. Box Volume vs. Manufacturer Recommendation
Compare your built or planned enclosure net volume against the subwoofer manufacturer's recommendation. Enter both volumes in cubic feet.
Within ±10% of spec is generally safe. 10–25% off will shift bass balance — fine-tune with boost or cut. More than 25% off — consult the manufacturer before pushing the system hard. Sealed box: too small = tight/thin bass; too large = loose/boomy. Ported: too small raises port noise; too large lowers tuning frequency.
