Unfortunately, the numbers presented in these videos are not just inaccurate but often completely illogical. Let’s talk about how we make power measurements and what information some of Read more
Let’s take a look at amplifier, speaker and subwoofer quality. This time, it won’t be a series of lab measurements that evaluate distortion, frequency response or power. It won’t even include listening evaluations or comments on shiny products.Many years ago, Rockford Fosgate ran a magazine advertisement showing a picture of a Punch 75 HD amplifier and Bruce. Bruce is Read more
A while back, I published an article that compared a high-quality Class-D amplifier with a low-quality “internet-brand” Class AB amp to prove a point about topology not being the deciding factor in performance and accuracy. The contrast in their performance was shocking, with the Class-D amp besting the AB in every way. An amateur YouTuber made a video breaking down the Read more
If you have taken part in any online discussions about radar detectors, then you know that manufacturers, retailers and so-called experts are extremely passionate about the brands they support. Countless tests, both scientific and anecdotal, extol the features, sensitivity and false-alarm rejection performance of a half-dozen key brands. Each test brings with it another heated Read more
