    REW Measurement Import

    Import a REW-exported measurement (frequency vs dB text file) and use it as the measured curve instead of the live mic.

    No REW measurement loaded.

    PEQ Filters (By Channel & Speaker)

    These suggested PEQ filters convert the band-level recommendations into concrete moves (center, Q, gain) that you can apply in your DSP software.

    DSP Interface – EDSP Bridge

    Select a saved tuning profile and an EDSP DSP model, then generate and launch the matching EDSP project file.

    Profiles come from the DSP & Tuning → Tuning Profiles card.

    Choose the exact EDSP model connected to the bike or vehicle.

    This file will be created or overwritten, then opened in the EDSP software.

    Full-page RTA View

    User Tools & System Calculators

    These tools help you size power wire and fuses, estimate port lengths, and figure out box volume in plain English. All measurements are approximate but more than good enough to sanity‑check your design before you build.

    Amplifier Gain Setup (AC Voltage Method)

    Set amplifier gain using a digital multimeter on the speaker outputs instead of guessing by ear. This works best with test tones and with all tone controls on the source unit set flat (no bass/treble boost).

    1. Turn all amp EQ, bass boost, and loudness controls off. Set the head unit EQ flat.
    2. Disconnect the speakers from the amp channel you are setting (or temporarily unplug the sub).
    3. Play a clean test tone that matches what you are tuning (e.g., 40 Hz for sub, 1 kHz for mids/highs).
    4. Turn the head unit up to the loudest volume you will ever use in real life (usually about 3/4 of max).
    5. Measure AC volts at the amp speaker terminals with your meter set to AC volts.
    6. Adjust the gain until the measured AC voltage matches the target voltage from the calculator below.

    Formula: V = √(P × R), where P is RMS watts and R is speaker load in ohms. For example, 150 W into 4 Ω needs about √(150 × 4) ≈ 24.5 V AC at the speaker terminals.

    Speaker Wiring Definitions (Parallel, Series, Series‑Parallel)

    Quick refresher on how total impedance changes when you wire multiple speakers together.

    • Parallel – positives tied together, negatives tied together. Total ohms goes down. Two 4 Ω speakers in parallel = 2 Ω total.
    • Series – amp + to speaker 1 +, speaker 1 − to speaker 2 +, speaker 2 − back to amp −. Total ohms is the sum. Two 4 Ω speakers in series = 8 Ω total.
    • Series‑parallel – series pairs in parallel (or vice‑versa) to keep the amp happy while using more speakers. Example: four 4 Ω subs wired series‑parallel gives a 4 Ω total load.

    Rule of thumb: most motorcycle amps are happiest at 4 Ω or 2 Ω per channel. Dropping lower can create heat and clipping unless the amp is specifically designed for it.

    Power Wire Size (Wire Gauge & Current Draw)

    About how many RMS watts do all of your amplifiers make together, how many volts does your system normally run at, and how long is the main power cable from the battery to the amps (one way)?

    Main Fuse Size

    Roughly how many RMS watts do your amps make, and what voltage does your system normally run at? This will estimate a sensible main fuse size with a safety margin.

    Port Length Estimator

    What is your net box volume (after sub and bracing), what tuning frequency do you want, what shape is the port, how many ports are you planning, and what are the port dimensions?

    Water Displacement → Air Space

    If you measured a bag or enclosure by filling it with water, enter the gallons of water used here to convert to cubic feet of internal air space.

    Simple Rectangular Box Volume

    For a basic rectangular box, what are the inside height, depth, and width (left‑to‑right), in inches?

    Irregular / Saddlebag-Style Box Volume

    For a saddlebag-style box, tell me the inside measurements in inches: how tall the bag is at the front and at the back, how far it is from the front wall to the back wall at the top and at the bottom at the front of the bag, and how long the bag is from front to tail across the top and across the bottom.

    Compare Box Volume to Subwoofer Recommendation

    How big is your box (in cubic feet), and what internal volume does the subwoofer manufacturer recommend for this driver in a vented or sealed box?
