Adding a subwoofer can be one of the most powerful upgrades you can make to any audio system — but only if it’s chosen and set up correctly.
In this comprehensive Subwoofers 101 guide, Ray Miller from Audio Advisor explains what subwoofers actually do, how to choose the right one for your room, and the setup techniques that make the difference between boomy bass and seamless, musical integration.
You’ll learn:
• What a subwoofer does (and why speakers alone miss the lowest octave)
• Sealed vs. ported subwoofers — sound differences explained
• How room size affects subwoofer choice
• How crossover, phase, and placement affect bass quality
• When to use one subwoofer vs. dual subs
• How streaming, CD, and vinyl benefit from proper bass
• Connection options: RCA, speaker-level, and wireless
• Common subwoofer mistakes to avoid
• Real-world guidance using REL, PSB, and MartinLogan subs
A properly integrated subwoofer doesn’t just add bass — it improves clarity, dynamics, and realism across your entire system.
