Showcasing the Best in the Mobile Enhancement Industry
The gain control is one of the most misunderstood features of a car audio amplifier. It is often mistaken for a volume knob, leading to improper usage and potential damage to the audio system. Understanding what gain control does—and doesn’t do—can help you set up your car audio system for optimal performance without risking distortion or equipment failure.Also, known as Read more
A reader requested that we compare the sound quality performance of wired and wireless Apple CarPlay. This is a great idea, as very little information is provided about the communication standards used to send audio signals wirelessly to a source unit. So, let’s look at distortion characteristics and frequency response to see if there is a performance difference. The Test Read more
At least once a week, someone comments on social media or in a forum that you can’t hear low-frequency distortion from subwoofers or amplifiers. We have no idea where this myth came from. However, if you understand what distortion is and how it works, you’ll know this myth is utter and complete nonsense. Yes, we know we’ve challenged the status quo. Don’t worry; we can always Read more
I was recently rewatching the YouTube video from GoldenSound about how he tested the quality of the MQA file format by uploading several test tones and part of a song to Tidal. 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
Our first subject in this series of articles about understanding subwoofer quality is a low-cost 10-inch driver from a local electronics parts store. This manufacturer markets this transducer as a “full range” speaker that “looks and sounds great” and not a subwoofer. We’ll start by measuring the Thiele/Small parameters of the driver, then break it in to see if things change Read more
Picking new speakers for your home, a new set of headphones or upgrades for your car audio system should all involve the same auditioning process. Take two or three of your favorite songs on a memory stick to a local mobile enhancement retailer and audition the speakers under controlled conditions. We can’t count the number of times people have purchased speakers based on a Read more
Few people in the car audio industry seem to grasp that speakers are typically the weakest link in audio systems, in terms of adding distortion to what we hear. Whether it’s a poor design with improper voice coil centering in the magnetic gap or poor magnetic or compliance linearity, speakers add significant amounts of unwanted information to what we hear. This article will Read more
Last week a friend of mine sent a link to a YouTube video by Steve Meade, who was experimenting with line output converters using an oscilloscope and an SMD DD-1+ distortion analyzer. Several statements in the video and the comments made it clear that people don’t understand the concept of audio signal distortion. That’s OK. It’s a complex subject and requires looking at Read more
Have you ever looked at something and thought you were only getting part of the story? Many previous articles have discussed amplifier distortion at length but haven’t delved into how power output levels and frequency affect distortion measurements. If you’re looking for the best amplifier for your car audio system, especially for midrange drivers and tweeters, this information Read more
