UNDERSTANDING: Getting too close

PS AUDIO / Paul McGowan One of our readers emailed me asking about proximity to his speakers. It was an interesting question. “As I move around the room I find the sweet spot to be 2 feet in front of my 8 foot separated speakers. Am I too close?” First, let me say I admire […]

LOUDSPEAKER CONE TECHNOLOGY: Ever wonder why loudspeaker designers get so excited about woofer cone materials like Kevlar, aluminum, paper, sandwich cones of carbon fiber, and other materials?

PS AUDIO / Paul McGowan Their excitement comes from understanding the challenge of making an air piston (which is what a speaker driver is) that can start and stop in perfect synch with the instructions from your power amplifier. To accomplish that feat one would prefer a cone (the piston part) that had zero mass […]

BIAMPING: I remember my delight the first time biamping speakers was explained to me

Paul McGowan The notion of using one amplifier perfectly matched to the tweeter and another to the woofer made such elegant sense. Tubes for the top end, solid state grunt for the bottom. Brilliant. That was at a time when the choices in amplifiers were limited. Big, powerful solid state amps sounded pretty poor reproducing […]

CROSSOVERS: Types of resistors for crossovers?

Dear Colin, I have just fitted stock 2R7 Panasonic 0.1% metal film resistors to replace the “green” 2R2 wirewounds in series with the Millennium tweeters in my WD25Tex speakers. I expected a change ( a bit warmer) but was not prepared for such a drastic change – is this due to the 0,5R increase or […]

READERS’ LETTERS: Does the CD layer of an SACD sound better?

A member writes: I think in order to store a DSD recording onto a disk it has to be stored on a SACD disk and played back on an SACD capable player otherwise if played on a standard CD player you would only hear the standard pressing and not DSD. —//— A member writes: SACD […]

READERS’ LETTERS: Understanding series and parallel speaker connections

A member writes: Damping Factor(DF) is equal to the impedance of the load divided by the out put impedance of the amp. For example if an amp has an output impedance of say0.1 ohms and the speaker is 8 ohms the DF is 80. If you have 2 8 ohm speakers in series the total […]

THE PERFECT SPOT: Your seating position IS compromised

Paul McGowan … If you’ve done your system setup homework your chair sits at a comfortable distance from the loudspeakers. With the precision of a ruler, you’ve tweaked and adjusted the speaker’s position for best imaging. Though we call it the sweet spot, it’s certainly not the perfect spot.

EXTERNAL vs INTERNAL / Is it better to have the loudspeaker crossover inside or outside the loudspeaker?

PAUL McGOWAN / PS AUDIO I was recently asked an interesting question. Is it better to have the loudspeaker crossover inside or outside the loudspeaker? At first, the answer seemed rather simple. Inside, of course. Shorter wires, fewer binding posts, etc. Yet, in thinking about it, I can see at least one advantage to an […]
