Banish the Hum

Find and Remove Hi-Fi Hum Without Test Equipment

Hum can come from a signal cable, a second grounding path, a digital connection, nearby electrical equipment, or vibration inside a component. This guide helps you find the actual source before you buy accessories or change your system.

Find where the hum begins: determine whether the sound is coming through the speakers or directly from a component's case.
Reduce and rebuild safely: start with the amplifier or powered speakers, then reconnect one cable or device at a time.
Confirm the real cause: repeat the result before treating grounding, digital, interference, mechanical, or connection problems.
Choose the right remedy: balanced connections, isolation transformers, ferrites, DC blockers, power products, or no accessory at all.

Loudspeaker Driver Materials

What Cones, Domes & Diaphragms Really Do

Paper, aluminum, beryllium, carbon fiber, polypropylene, silk, ceramic, and composite diaphragms all behave differently. This guide explains what those material differences actually mean and why the material name alone never tells the whole story.

Stiffness versus mass: understand the fundamental tradeoff behind diaphragm design.
Breakup behavior: learn what happens when a driver stops behaving as a rigid piston.
Internal damping: see why some materials suppress resonance while others require more careful engineering.
The complete driver: material, geometry, motor, suspension, enclosure, and crossover all determine the final result.

The Disappearing Subwoofer

Deep Bass That Sounds Like Part of the Music

A practical guide to getting deep bass that integrates with your system instead of calling attention to itself. Learn what actually matters when placing, setting up, and integrating a subwoofer so the bass sounds like part of the music, not a separate box in the room.

Placement that works: understand room interaction and where the subwoofer actually belongs.
Phase & timing: get the subwoofer and main speakers behaving like one system.
Crossover & level: build low-frequency extension without boom, gaps, or obvious overlap.
The disappearing effect: bass you hear and feel without being able to locate the box producing it.

Beyond Watts

Speaker & Amplifier Matching Without the Guesswork

Why can two 4-ohm speakers demand completely different things from the same amplifier? Beyond Watts explains the complete pairing, not just the wattage number on the spec sheet.

The complete speaker load: impedance, phase, enclosure, crossover, and EPDR together.
Your listening requirement: sensitivity, distance, and musical peaks translated into voltage, current, and power.
Amplifier capability: clipping, current limiting, heat, protection, amplifier class, and bench measurements.
A repeatable matching method: worked calculations, four speaker cases, and a final six-step checklist.

HiFi without the mystique.

Great audio gets easier to understand when somebody is willing to explain what the equipment is actually doing.

Whether you're building your first serious system or you've spent years chasing better sound, Analogholic is a guide through the engineering, equipment, and choices that shape what you hear.

That means honest, in-depth coverage of amplifiers, speakers, turntables, phono stages, cartridges, digital gear, and the system interactions that rarely fit neatly on a spec sheet.

We go deep when the subject demands it, but the goal isn't to make HiFi sound complicated. It's to make the complicated parts understandable enough to use.

And underneath all of it is the reason the equipment matters in the first place: the music.

Your explanations are elegant. There are a handful of good technical HiFi discussions on YouTube. Your channel is unparalleled in describing every process. Remarkably you do it in a way that non-engineers like me can understand. You have become my favorite professor. Thank you!
