Stand Loudspeaker Reviews

When I got these new speakers for review, they were so new that, at the time I unpacked them, no official user manual was included or posted on the manufacturer's website, and the promised matching stands didn't exist. Yet, I have the abiding feeling that I am getting to the party long after it has started. The Mobile Fidelity SourcePoint 8 is the newer, smaller sibling of the SourcePoint 10 reviewed by John Atkinson in Stereophile's February 2023 issue, with a follow-up by Ken Micallef in June.

Four products were subjected to second opinions in recent issues: Herb Reichert reviewed the Mk.II version of Klipsch's Reference Premiere RP-600M loudspeaker (above left); Ken Micallef wrote about his time with the MoFi Electronics SourcePoint 10 loudspeaker (above right); John Atkinson lived with the CH Precision I1 Universal integrated amplifier (above); and Julie Mullins auditioned Triangle's Antal 40th Anniversary Edition loudspeaker.

The Acelec Model One speakers I'm auditioning ($6495/pair) are not princesses in pink, or frog green, or made of some chemically distilled polypudding. Nor are they conventional-beyond-reason MDF boxes covered with stick-on vinyl pretending to be wood. The Model Ones are squat, small, serious-looking, two-way standmounts. They are 11.2" tall, 7.7" wide, 11.5" deep, and 37.5lb heavy.

The most money I've ever spent on a pair of loudspeakers was back in the early 1990s, when I bought a pair of used TAD TH-4001 wooden horns and their associated TD-4001 compression drivers. The TAD horn's smooth, micro-resolved response was a refinement upgrade from my multicell Altec horns; plus, the TADs' French-polished wood looked radically less industrial than the soldered-tin, tar-filled 1005/288C horns they replaced. None of my horn-fanatic friends had anything sonically or aesthetically comparable, and all of them were envious. I didn't keep the TADs long, because the friend who admired them most made me a very "friendly" offer.

That was my first experience with Japanese loudspeaker design, and it exposed me to a level of engineering precision and fine craftmanship I had not yet encountered in American-made speakers.

I'm picturing a gaggle of cigar-chomping Simaudio execs in an office discussing what to do about the fact that their high-end amplification lines have become so successful that their names have become synonymous with the company. "In the '90s, people thought our company was called Celeste," one floor-pacing exec says, speaking for everyone in the room. "Now they think we're called Moon! How do we fix this?" After much debate, a member shouts: "We add 'by Simaudio' at the end!" The execs hoot, holler, and slap the conference-room table—and thus is born Moon by Simaudio.

A fictional account? Sure, but, as they say in the movies, it's based on a true story.

Almost five years after I submitted my review of Dynaudio's Focus 200 XD class-D active bookshelf loudspeaker—my first product review for Stereophile—word of its imminent successor, the digital Focus 10 class-D active bookshelf loudspeaker ($5500/pair), and its two larger siblings arrived via Mike Manousselis, Dynaudio North America's president, Americas. Then came the near-ubiquitous parts shortages and COVID-related slowdowns that have plagued high-end manufacturers worldwide.

"A 10" two-way?!?!" I couldn't help gasping in surprise when I unboxed the MoFi Electronics SourcePoint 10 standmounted loudspeakers, which cost $3699/pair.

Some background is in order. Using a large-diameter woofer endows a conventional two-way speaker with potentially high sensitivity and extended low frequencies. However, the large woofer's radiation pattern narrows at the top of its passband, whereas that of a tweeter mounted on a flat baffle is at its widest at the bottom of its passband. Even if the drive units' outputs are well-matched in the speaker's on-axis response, this discontinuity in the speaker's off-axis behavior results in an in-room balance that will sound bright. This is why favorably reviewed two-way designs tend to use a woofer with a 6.5" or even smaller diameter.
