Your Subwoofer Can Sound Better
In The Spot It's Already In.
AudioBro measures your room's bass response and tells you exactly what to adjust — crossover, phase, level, and position — one change at a time.
Does This Sound Like Your Room?
Boomy or Missing Bass
Some notes overwhelm the room while other bass frequencies completely disappear.
Integration Problems
You can clearly hear the subwoofer separate from the main speakers instead of a seamless blend.
Guessing at Settings
You are blindly twisting crossover and phase knobs hoping for a better result.
From Problem to Progress in Three Steps

Make one physical change and re-measure to verify
See How It Works
Sample Bass Data Analysed
AudioBro processes a sample in-room bass sweep to reveal how the subwoofer interacts with the room — peaks, nulls, and roll-off.
Main Bass Issue Detected
The sample data shows a dominant bass problem — a room mode reinforcement at the listening position causing uneven response below 80 Hz.
One Variable to Change
AudioBro narrows the fix to a single adjustment — placement, crossover, phase, or level — that addresses the root cause, not the symptom.

Frequently Asked Questions
Do I need REW for this?
You can upload REW measurements, or you can use our in-browser sweep generator to capture the data directly.
Is the in-browser sweep high quality?
Yes, our sweep generator provides sufficient low-frequency resolution to accurately assess subwoofer integration issues.
Does this work with multiple subs?
Tune My Sub provides baseline guidance for aligning your primary subwoofer. Complex multi-sub DSP optimization requires advanced analysis.
What specific changes will it recommend?
It will suggest actionable adjustments to your receiver's crossover frequency, subwoofer phase, distance settings, and physical placement.
How does verification work?
You make the recommended physical or setting change, run another sweep, and AudioBro confirms whether the response improved.
