Tannoy SGM-1000
A 15-inch Super Gold studio monitor that turns up in classified ads more often than in spec sheets. That says something about who owned them.
Overview
The Tannoy SGM-1000 is a 15-inch studio monitor built around the company's Super Gold driver, the same dual-concentric lineage that put Tannoy in professional rooms on both sides of the Atlantic. What documentation survives for this model is almost all in the classified columns of the recording trade press, where the SGM-1000 shows up repeatedly as a used item and not a reviewed one. That's not a knock. These were working speakers, bought by studios that kept them until the rooms closed.
The clearest paper trail is the used-equipment listings in Recording Engineer in the late 1980s. By then the trade press had been covering Tannoy's professional monitors for decades. As Studio-Sound (June 1990, p.28) noted, Tannoy had been active in almost every area of speaker application since its founding in 1926. TekCom Corporation, a Philadelphia pro-audio dealer, advertised "Tannoy SGM-1000 15" super gold monitors" at $2,600 a pair in one issue and $2,500 in another, alongside a Meyer 833 system and the smaller Tannoy SGM-15B reference monitors. A separate TekCom listing from the same period paired the SGM-1000 with an Otari MTR-12-I half-inch four-track. These were sold into project and mid-tier professional rooms, not hi-fi salons.
The "15-inch Super Gold" descriptor is the one technical fact that follows the model across every listing. Super Gold is Tannoy's dual-concentric driver family. A high-frequency unit sits concentrically at the throat of the woofer, so both drivers share a single acoustic center. That gives point-source imaging and a coherence through the crossover region that conventional two-way boxes struggle to match, and it is the reason studios kept specifying Tannoy.
The surviving listings leave out nearly everything else. There is no confirmed frequency response, no sensitivity figure, no impedance, no crossover point, no cabinet dimensions, and no weight in any source examined for this entry. Production years are also unconfirmed. The model appears on the used market by the mid-to-late 1980s, advertised alongside contemporary Tannoy studio offerings, but no source establishes when it was introduced or when it was discontinued. Be suspicious of any firm date quoted elsewhere.
The classifieds are worth reading carefully for condition. The SGM-1000 listings that survive are dealer ads, not private sales, which means the speakers were typically traded in as part of a studio's upgrade cycle and not sold off piecemeal. That's usually good news for a buyer, since pro rooms tend to maintain their monitors. It also means many surviving examples have probably been re-coned, re-foamed, or had their crossovers recapped at least once. Dual-concentric drivers are unforgiving of sloppy recone work, and the HF unit sits in the most awkward possible place to service. Anyone buying a pair today should budget for a proper inspection of the concentric assembly before trusting it.
Price history is thin but consistent. The $2,500 - $2,600 asking prices from the late-1980s TekCom ads are the only concrete figures available for the SGM-1000. Read them as dealer retail for used stock at the time, not original MSRP. Original pricing, if it was ever published, hasn't surfaced in the sources reviewed here.
The SGM-1000 sits in a crowded corner of Tannoy's professional output. In the surviving record it stands out less for its specification than for its channel: studio classifieds, pro dealers, bundles with tape machines, and prices in the working-professional bracket and not the audiophile one.
The SGM-1000 is a Tannoy 15-inch Super Gold monitor with a documented presence in late-1980s professional studios and almost no documented specification. A buyer who finds a pair is getting the driver technology and the Tannoy house sound, not a paper trail. Check the cones and the crossovers, and don't pay Super Gold prices for a cabinet that's been through three studio refits.
