When setting a subwoofer up should its frequency limits match those of the main speaker or lower or higher? This is a question asked a lot and Paul helps us understand the intricacies of the all-important setup process.

The loudness wars, or the war against dynamic range, is still alive and well and that is unfortunate. But, there’s hope and Paul helps us understand the beginnings of the loudness campaigns and why they are so prevalent today.

Some loudspeakers feature rear mounted tweeters in addition to their front mounted tweets. What are these rear ones for and what advantages do they offer music lovers?

Nights, days, weekends, workdays, the stereo sounds different to this viewer. Paul explains why and offers an interesting solution to an age-old problem that has plagued many a high-end stereo user for many years.

You’ve said in the past that measurements cannot tell us how electronics sound. Please explain why this is true and how specifically, THD isn’t a good indicator of sound quality.

Here’s a problem Paul has struggled with for nearly 40 years and still, to this day, he only has succeeded in solving a partial bit of this terribly difficult problem. Find out his thoughts on why stereo systems do not replicate the sound of live music and what is being done to solve that problem.

Polarity controls are rare on equipment and this viewer wonders why and Paul does his best to explain what a polarity (or phase) switch is and why it’s not trivial to add it to a piece of equipment.

If subwoofers were able to roll off the bottom end of the main loudspeaker, wouldn’t there be advantages like greater clarity, lower distortion, and less power spent? And, if that’s true, why don’t manufacturers offer such filters with subwoofers?

Subwoofers help our systems come alive by bringing the realism associated with live events into our homes and supplementing where our main speakers fall short. But they only go down so low. Is it possible to go lower than what a conventional subwoofer does? Enter the Rotary Sub.

We’re all on some type of budget and this question revolves around how best to spend those dollars when building a high-performance audio system. From the under $1,000 killer system to the $100,000 killer setup, choosing how and when to spend money is an art.
