Understanding how DC voltages combine is quite simple. They add linearly when we wire sources (like batteries) in series. But understanding how AC waveforms combine is complicated. AC waveforms don’t always sum intuitively unless the peaks and valleys align perfectly. We see many examples where people interchange the terms phase and polarity. In reality, those words refer to Read more
The BMW M340i is not quite the BMW M3, but not quite the base model 330i. But what is nice is the standard non-controversial grille that has put so many people off the M3’s new snout. Forgetting the highly debated grille, the BMW M340i offers daily performance wrapped in a luxury package. For years it was the benchmark sports sedan.

These amplifiers are categorized Class SB and Class SBI. Read more

His results showed without any shadow of a doubt that the MQA format didn’t meet many of the claims made by the company. This article isn’t about MQA, thankfully.I’ve often wondered about the quality Read more
When a person thinks of Cadillac, old timers think of the tail-finned luxury convertibles of the 1950s, while Gen Z probably thinks of Escalade. That nameplate has become the pinnacle of the brand, and its biggest moneymaker. I recall attending a previous-generation Escalade release with a not-yet-President Donald Trump speaking about the vehicle. If you’re a wealthy Read more
Any time your installer wants to wire two subwoofers to the same channel of an amplifier, they can wire them in series or parallel. The same goes for a dual voice coil design subwoofer. The only benefit of a DVC subwoofer over a single is that there are three wiring options. We examined whether the wiring options for dual voice coil subwoofers differed a while back. Thinking Read more
