Electro-Voice EV-11
The EV-11 exists in this archive as a filename and nothing more.
Overview
This entry has no verified specifications, no confirmed production years, no design documentation, and no independent period coverage behind it. The Electro-Voice EV-11 is a single PDF in the source index whose filename carries an "EV-11" attribution. The document never names the EV-11 anywhere in its text. That is the entire evidentiary basis, and it does not support a product page.
The document is an Electro-Voice product newsletter, Speaking of EV..., Volume 1, Issue 1, dated November 2000. It is a house organ, not a product catalog. The lead story covers a cluster of New York City club installations - Baby Jupiter, Arlene's Grocery, The Saint, Scandals, Tuna Fish, and The Bitter End - all running EV reinforcement systems built around SX300 and SX500 loudspeakers, MTL1x, T-18, and SB180 subwoofers, DX38 processors, and N/D767A microphones. A second item covers an X-Array deployment for a Sydney concert, listing XF 40x20 and XN 60x40 cabinets, XB and XDS subs, and DX 38 digital controllers. None of those is an EV-11, and the string "EV-11" does not appear in the newsletter's text at all. The attribution is a filename artifact, the kind of indexing noise this archive flags instead of turning into a product entry.
The magazine chunks retrieved with the same query say nothing about the model either. They are Electro-Voice brand advertising from the late 1960s, the "Take a long look at the new shape of progress" campaign, which ran in High Fidelity (September 1967, p.131), HiFi-Stereo (August 1967, p.108), and again in High Fidelity (November 1967, p.22). The copy is corporate, not model-specific. EV built a microphone seven feet long to solve long-distance pickup for radio and television, squeezed a 65-watt FM stereo receiver into less than 3-1/2 inches of height, and kept putting bigger sound into smaller speaker systems. Two 1969 Audio installments of the "Sound & Decor Styles" feature describe a Rosner Custom Sound installation in Kings Point, Long Island. It had five stereo listening locations, Klipsch Model "H" systems built into walls and cabinetry, Bozak "Bards" on the patio, and Electro-Voice Regency enclosures running Stephens 12-inch speakers. None of that concerns a product called the EV-11.
So what can be stated is narrow. An "EV-11" identifier is attached to an Electro-Voice source document in the archive's index. The document dates to November 2000 and concerns club and touring sound reinforcement. The available material can't say whether the EV-11 was a loudspeaker, an amplifier, a microphone, a crossover, a mounting accessory, or just a mislabeled file. The 1960s - 1970s date range in this page's metadata reflects only the era of the surrounding Electro-Voice brand material, not any verified production window for the model.
Anyone looking here for specifications, production dates, or market values won't find them, and the archive won't make them up. If an EV-11 exists in someone's collection, as a real model with a real faceplate and a real serial number, this page needs that documentation. A service manual, an owner's manual, a catalog page, a photograph of the rear panel, or even a period dealer listing would be enough to begin.
