Floor Loudspeaker Reviews

What's 1/16" narrower, over 1/2" shallower, and 3/16" higher than the Mirage M-3 loudspeaker? The new Mirage M-3si, that's what. Though the published dimensions for the old and new speakers are the same, my eyes told me there was a difference between them when I had them side-by-side in my listening room in Santa Fe. Being the compulsive type, I got out my trusty tape measure. No, my eyes had not deceived me—the M-3si is skinnier and taller. As I waltzed them into position, I sensed they weighed about the same as their predecessors; close enough that setting them on Arcici Super Spikes is a two-man operation. Though either speaker makes a definite presence in a room, I still find their high-gloss, black finish (the only finish available) unassuming, attractive, and elegant.

The concept of a loudspeaker with its own built-in amplification is an idea whose time should long since have come. Technically it makes a lot of sense, and in some parts of the world—not to mention professional circles—it's quite popular. But commercially, the idea has never really taken off in this country. And while the loudspeaker manufacturer should be in a better position to make the best amplifier choice, American audiophiles seem wedded to the idea of making their own amplifier/loudspeaker match.

"Is that it?" I asked.

Loudspeakers from British manufacturer Monitor Audio have consistently received favorable reviews in Stereophile over the past decades. From the R952MD I reviewed in January 1988 to the Silver 500 7G reviewed by Rob Schryer in February 2022, Monitor Audio speakers have offered excellent sound quality and high-quality engineering. So when I was offered the company's Platinum 300 3G for review, I readily agreed. Having lived with standmounts and minimonitors for the past year, I felt it would be good to spend some time with a pair of large, full-range, three-way floorstanders.

Monitor Audio's Platinum PL300 II loudspeakers weigh 120 lbs each, and my listening room is on the second floor, but I was spared the heavy lifting. The speakers were delivered by Sheldon Ginn, Jeffrey Ginn, and Jamie Arseneau—respectively, the VP of Sales and Marketing, Account Manager, and Service Manager of Kevro International, Monitor Audio's North American distributor. We set up the PL300 IIs, ensuring that the distance from each speaker to my listening seat was the same, then optimized the toe-in: the speakers ended up almost directly facing the listener position, close to where I'd had Wilson Audio's Sabrinas.

It seems to me that my review of Monitor Audio's Silver 8 loudspeaker was published only a few months ago. Actually, it's been three years. The Silver 8 so impressed me that I bought three of them, along with two Silver 2 bookshelf speakers, for my multichannel system in Connecticut—and still greet them as the newcomers to my system. So installing and reviewing their successors, the 300, from the sixth generation of Monitor's Silver line, seemed very familiar.

I remember reading about Monitor Audio speakers as I pored over British audio mags in the 1970s, before the economy was globalized. They were among the many worthy UK brands whose cachet was amplified by their unavailability in the US. This venerable brand has survived and flourished, while many others from the 1970s have disappeared, or become mere labels under the aegis of multinational corporations. The reasons for this success seem to be that Monitor has evolved their metal-cone driver technology, kept the focus on their core market, and continued to provide high-quality construction and finishes. So I was not surprised to read, at the back of the Silver 8's multi-language owner's manual, that the speaker was "Designed and Engineered in the United Kingdom, made in China."
