System measurement
Frequency response, phase, and arrival-time measurements to understand how the loudspeakers interact with each other and the listening space.

Better sound.
By measure.
Get your loudspeakers working together. Sound system measurement, alignment, and DSP tuning for clearer sound, tighter bass, and more consistent coverage.

01 / What I do
Make the most of
the system you have.
If the bass feels uneven, the tops sound disconnected, or the room changes dramatically from spot to spot, start with the system—not another guess at the EQ.
Subwoofer alignment
Evaluate placement, polarity, and delay to improve summation across your subwoofer array and its integration with the mains.
Crossover & DSP tuning
Check crossover integration, relative levels, delay, and EQ. Make adjustments based on measured behavior and listening.
Coverage & delay fills
Assess speaker positioning and aiming. Align delay speakers with the mains and check how the result changes through the audience area.
Signal-path troubleshooting
Trace routing, gain structure, amplifier settings, and channel assignments to find problems before tuning around them.
Event & venue optimization
On-site support for installed systems and temporary rigs, with practical adjustments shaped by your room, equipment, and event.
02 / The process
Listen. Measure.
Align. Verify.
A deliberate process, from the signal path to the listening area. The goal is a system that works together where your audience actually stands.
Understand the setup
Discuss the problem, inspect placement and routing, and establish a baseline.
Find the relationships
Measure individual sources and combinations from positions selected for the task.
Bring it together
Work through placement, polarity, timing, levels, crossover integration, and EQ.
Check the listening area
Remeasure, compare positions, and listen to music before reviewing the final settings.
03 / Behind the measurements
A system engineer.
A listener first.
I’m Mathew Bagshaw, an audio systems engineer with hands-on experience providing and operating sound systems since around 2010.
My background combines live sound, event production, DJ performance, and system measurement. I understand what a system needs to deliver when the room fills up and the music starts.
Based in the San Fernando Valley, I work with venue owners, system providers, and event producers across Southern California.

system do better?
