Electro-Voice SH-1502ER
A 15-inch two-way that Electro-Voice let working musicians sell for them — one quote at a time.
Overview
Electro-Voice took an unusual route to market with the SH-1502ER. Instead of leaning on a spec sheet, the company built an advertisement around testimonials from the people it was actually trying to reach — working players and engineers. The pitch ran in the music trade press with a simple framing: you could have dismissed the company's earlier claims as "parental pride," but now hear it from your fellow pros. A rock keyboardist from Wellington, Kansas called the system "surprisingly crisp" and said he loved the range. A Phoenix sound engineer described smooth response that stayed excellent through the vocal range. A country/gospel monitor mixer from Ferndale, California reported no muddiness in the low end and a crisp top. That's marketing copy, not an independent verdict, but it tells you exactly who Electro-Voice thought this box was for: the person loading it into a van, not the person auditioning it in a showroom.
The architecture is straightforward and purposeful. The SH-1502ER is a two-way system built around the DH2010A titanium-diaphragm high-frequency driver, paired with a horn using Electro-Voice's Time-Path phasing plug and a 90° x 40° constant-directivity pattern. That coverage figure is the practical heart of the design — 90 degrees wide and 40 degrees tall is a pattern meant to spread the mid and top across a room without spraying energy into the ceiling. According to the company's own literature, the high-frequency output delivers flat response to 20,000 Hz, with particular attention paid to the 12,000-to-20,000-Hz range where, as the copy puts it, many systems fail. The claim is that the DH2010A captures the shimmer of a cymbal and the upper harmonics that give vocals their sizzle. Whether the driver fully delivers on that is a matter of taste, but the design intent is unambiguous.
Down low, both the SH-1502ER and its sibling the SH-1512ER use the EVG 15-inch woofer, built with a flat-wire aluminum voice coil and rated at a long-term power handling capacity of 200 watts. Electro-Voice's advertising was careful to call that rating conservative — the phrase used was that the EVG-15 is "conservatively rated at 200 watts," delivering distortion-free sound with good transient response even at the high sound-pressure levels and dynamics common to live performance. The distinction between the two models matters here: the SH-1502ER is the vented, horn-loaded version, which the literature describes as offering extra sensitivity and power, while the SH-1512ER is the direct radiator pitched at what the company called "balanced warmth." Same woofer, same HF driver, different low-end loading — and a different character as a result.
The cabinet is where the working-musician argument gets concrete. The SH-1502ER uses what Electro-Voice branded its Road-Wood enclosure — a design covered by patent #4,624,338 — described as carefully fitted and bonded, then wrapped in durable abuse-resistant carpeting to survive years of hard use. That's not a cosmetic detail. A speaker that lives in and out of clubs takes a beating on load-in and load-out, and the Road-Wood construction and carpet covering are the company's answer to that reality. The other practical concession is the warranty: five years, which the advertising itself calls a rarity in speaker systems for the working musician. For a box that's going to get thrown in the back of a truck, a five-year warranty says more than a frequency-response plot.
The SH-1502ER also shows up in the broader trade-press record as a demonstration item rather than a review subject. A West L.A. Music DJ show in the fall of 1987 listed "Electro Voice SH 1502ER and SH 1512ER speakers" among the new-product seminars alongside gear from a long roster of manufacturers — the kind of placement that puts a speaker in front of working DJs and club owners rather than hi-fi reviewers. That's consistent with everything else in the surviving material: this was a system sold to people who needed it to be loud, clear, and durable, and who judged it in a room full of people rather than in a listening chair. The company's own closing line in the testimonial ad put it plainly — audition a pair and let your own ears make the final decision.
What the record does not establish is when the SH-1502ER was introduced, what it originally sold for, or how it compares on paper to anything else in the catalog. The surviving documentation is advertising and trade-show listings, not test reports, and it would be dishonest to dress that up as more than it is. The trade press of the period was busy with new-product announcements of every kind — Recording Engineer (November 1987, p.64), for instance, ran a New Products column covering items like the Symetrix 511A noise reduction unit — but the SH-1502ER itself appears there only as a listing, not a reviewed subject. What can be said is that Electro-Voice built this system around a specific set of priorities — a titanium HF driver with a constant-directivity horn, a 200-watt 15-inch woofer, and a cabinet engineered to survive the road — and then marketed it to the people who would put those priorities to the test. Collectors and working players who run across one should expect the same thing the original buyers were promised: a box built to take abuse and stay intelligible at the back of the room.
