Speaker Wiring
How to Wire Speakers: A Practical Guide
Polarity, series and parallel, and how each connection changes the load your amplifier sees.
8 minSeries vs. Parallel Speaker Wiring
How each wiring method changes total impedance — and when to reach for one over the other.
7 minHow to Calculate Speaker Impedance
The formulas for series, parallel and series-parallel — plus an interactive calculator.
6 minHow to Connect Multiple Speakers to an Amplifier
Series, parallel and series-parallel — connecting several speakers to one amp safely.

Impedance & Power
How Speaker Impedance Works
What impedance really is, why it is measured in ohms, and why the amplifier cares.
7 min4-Ohm vs. 8-Ohm Speakers
What the ohm rating changes for your amplifier — and which to choose.
6 minMatching Speakers to Amplifiers
Impedance, power ratings and headroom — matched safely, without the myths.
8 minWhat Happens If Speaker Impedance Is Too Low
Why too low a load stresses an amplifier — what happens, and how to avoid it.

Speakers Explained
Passive vs. Powered Speakers
Where the amplifier lives, the trade-offs of each, and which suits your setup.
6 minWoofer vs. Subwoofer
The frequencies each handles — and when you actually need a subwoofer.
5 minSpeaker Sensitivity and SPL
What sensitivity means, how it relates to loudness, and why it beats wattage.
