The Shun Mook Affair Sam Tellig

Shack Attack
Stereophile Vol.17 No.11 November 1994

I hied me down to Radio Shack to see what I could find on sale. Lo, I discovered the Optimus 990 speakers (catalog #40-1125) marked down from $149 each to $98 each. That's $196/pair. I pounced (at least to the tune of a 30-day money-back trial).

Each speaker has a horn tweeter, and its 15" woofer is said to provide "thunderous" bass. Specs are sparse: 100Wpc maximum power handling (minimum not specified). I set the speakers up on 12"-high Target stands and hooked them up to the 7W SE-1.

Wow. Now this…

Snake Oil!
Editor:
I am writing you once again in hope of expounding my philosophy on less-deaf ears than I witnessed this weekend past.

Partaking in what I believed to be an investigative effort in what I also believed to be a respectable audio salon in northern New Jersey, I witnessed no serious effort in seeking out musical truth, but rather an exercise in self-indulgence at the expense of the latter: A group of "audiophiles" sliding wood across the top of various gear, claiming "There, no there...that's it!"

I've been to…

You remember Dustin Hoffman and "Larry" Olivier in The Marathon Man: "Is it safe?" Just when you thought it was safe to go back in the water. Just when the Shun Mook bashing on Internet had slowed down to but a mere bubbling caldron of skepticism. Just when a particular towheaded colleague…

First Movement
We listened carefully to the system in its present configuration. Acoustic treatment is relatively light in our live listening room. We've pulled the behemoth Avalon Ascents well out into the room, so we're no longer fighting the natural acoustic---as we were when they were deeper into the L-shaped portion of our loft. Now mostly unencumbered by side walls (and their reflections), the Avalons can breathe, sounding much more expansive and spacious. With just a slight toe-in, the soundstaging is staggering, if I do say so myself.

It's a big sound, with images forming well…

At various points during the process we coaxed Kathleen into the listening chair, even though she typically prefers listening off-axis while otherwise engaged. She leaves all that sitting and squinting to me. When pressed, she felt that the single greatest effect she'd heard was due to the placement of the two additional Mpingo Discs on the speaker-top "control areas" (in addition to the single Disc already placed on the outside rear corners). I'd have to agree.

The Monks' tuning instructions are as follows: Raising the front Mpingo'd shelves upward lightens up the sound and brings more…

Cabasse Artis Baltic II & Thor II loudspeaker system

A proper speaker installation can take a full day and sometimes part of a second, even in a familiar room. But by the time the sun sets on Day One, the system should be almost there—wherever there is.

But imagine, at the end of Day One, the following scenario: Three exhausted, chain-smoking tech types dart frantically around the room. One moves a pair of subwoofers, one tweaks a half dozen or so unmarked potentiometers mounted in a small aluminum box; the third supervises these changes, then listens for what seems like the 150th time. Then, for what also seems the 150th time, collective…

Like any other sat-sub system, the Cabasse Thor-Baltic combo is ripe for abuse. Better too little bass than too much. While the system has the potential to drive audiophiles crazy—especially those who thrive only on certainty—I found that, once the system was dialed in correctly, I left it alone. In the end, I felt that, in order to avoid hearing "bass," as opposed to instruments creating bass, I had to run the system slightly leaner than what I thought sounded like neutral. But overall, I was happy with the blend and never found myself fiddling with it.

The only change came when Cabasse…

Cabasse Artis Baltic II & Thor II loudspeaker system Measurements

Sidebar 3: Measurements

The Artis Baltic II "eyeball" had a high estimated voltage sensitivity of 90.5dB(B)/2.83V/m. Its impedance (fig.1) dropped to or below 4 ohms in the lower midrange and mid-treble but was otherwise quite high. The speaker should not, therefore, be difficult to drive, though its use of a series capacitor to roll off the lows below 80Hz results in a combination of 6.7 ohms magnitude and –45° electrical phase angle at 73Hz, which might tax underpowered amplifiers.
