Electro-Voice EVID C8.2HC
An 8-inch coaxial ceiling speaker for high-ceiling applications. It ships with everything you need to hang it.
Overview
Most ceiling speakers are an afterthought: a hole, a grille, and whatever sound happens to spill out of it. The Electro-Voice EVID C8.2HC is not that. It is an 8" two-way coaxial loudspeaker system built for high-ceiling applications. The whole design goes after one problem, getting clear music and speech out of a speaker mounted 20-plus feet above the audience.
The answer, according to the manual, is an 8" coaxial transducer feeding an "innovative waveguide (patent pending) that provides directivity control to 1 kHz." That means the speaker throws a defined cone of sound rather than spraying energy in every direction. As the documentation puts it, the C8.2HC "provides much better music fidelity and speech intelligibility in spaces with high ceiling heights than typical flush units are capable of." Directivity control means the speaker covers the same floor area as a typical flush-mount unit. One speaker does the work of several, and the sound goes to the listener instead of bouncing off the walls.
Inside the coaxial assembly sit an 8" woofer and a 1" titanium-coated tweeter. Sources describe the driver complement as an "8" Waveguide Coupled Coaxial Speaker with Horn Loaded TI Coated Tweeter," and the titanium coating keeps the tweeter rigid and controlled at high frequencies. The low-frequency driver is loaded into a ported enclosure, a rear back-can that the manual says provides "an optimum internal volume for extended low-frequency performance." That ported alignment is why the C8.2HC reaches down to a rated 50 Hz (-10 dB) rather than the anemic 120 Hz you get from a lot of open-baffle ceiling speakers. It is sold as a pair, with tile bridges, a backing plate support, cutout templates, and a paint shield.
The transformer is where the C8.2HC gets interesting if you have wired a commercial distributed system. The speaker has an integrated line-matching transformer for 70 V, 100 V, or 8-ohm use, with a front-panel mode and wattage selector. Transformer taps are 7.5 (70 V only), 15, 30, and 60 watts. The same box can serve a constant-voltage distributed line in a shopping mall or a low-impedance 8-ohm channel in a smaller room, and the tap is changed with a switch on the front baffle rather than by rewiring. Electro-Voice's own literature frames the C8.2HC as a complete two-way ceiling loudspeaker package, and the included mounting support ring and tile rails mean most installations need no additional accessories.
One thing to sort out before buying: there is a second-generation model, the EVID-C8.2HC-G2, and it is a different speaker. The G2 uses a different transformer tap set (5.6, 11.3, 22.5, 45, or 90 watts), and its published coverage angle is 75° conical. The original C8.2HC, the subject of this page, is the one with the 7.5/15/30/60-watt taps and the 50 Hz–20 kHz rating. The two are easy to confuse in listings, so check the suffix.
Key Features
Waveguide-Coupled Coaxial Driver
The C8.2HC is a coaxial design, so the 1" titanium-coated tweeter sits at the center of the 8" woofer rather than beside it. In a ceiling speaker this keeps the high and low frequencies time-aligned and radiating from the same point, which preserves intelligibility off-axis. The patent-pending waveguide couples both the low-frequency and high-frequency drivers and controls directivity up to 1 kHz. Below that frequency, the waveguide stops steering and the room takes over.
Electro-Voice's own copy describes the model as "maximum fidelity and intelligibility for high ceilings," and the waveguide is the reason. A conventional flush-mounted ceiling speaker with a wide, uncontrolled pattern sends most of its high-frequency energy into the walls and ceiling, where it turns into reverberation. The C8.2HC aims that energy at the floor instead.
Front-Panel Transformer with 7.5, 15, 30, and 60-Watt Taps
The integrated line-matching transformer makes the C8.2HC a system component rather than just a speaker. It accepts 70 V or 100 V distributed lines or an 8-ohm bypass, and the wattage tap is selected with a switch on the front of the waveguide. Available taps are 7.5 (70 V only), 15, 30, and 60 watts. That range lets an installer dial in the SPL needed for a given zone without swapping hardware. A 60-watt tap on a 100 V line draws more power and plays louder. A 7.5-watt tap on a 70 V line sips current and suits background-music zones.
At least one vendor listing describes the C8.2HC as "the low-impedance version, meant for conventional amplifier channels where each speaker or pair gets dedicated power." That is only half the story, since the transformer is there so it can also run on a distributed line. Buyers should confirm which mode they need before ordering, because the tap configuration is fixed at the factory and the selector only chooses among the available taps.
Ported Back-Can Enclosure
An open-back ceiling speaker relies on the plenum above the tile as its enclosure. The C8.2HC ships with a complete back-can instead. The manual notes the rear enclosure provides "an optimum internal volume for extended low-frequency performance." The ported alignment is what gets the rated low end down to 50 Hz (-10 dB). For music in a restaurant or retail space, that counts, because a sealed or open-back ceiling speaker rolls off well above 100 Hz and sounds thin on anything with bass content.
The back-can also has a practical job in commercial construction. It isolates the rear radiation of the driver from the plenum, which keeps sound from leaking into adjacent rooms through the ceiling void. The package includes the back-can, tile rails, and mounting ring. One source describes the kit as "complete with mounting support ring and tile rails. No additional accessories needed for most installations."
Power Handling and Frequency Response
Electro-Voice rates the C8.2HC at up to 100W of RMS power, with a frequency response of 50 Hz to 20 kHz (-10 dB). One retailer lists continuous power handling at 75W at 8 ohms, a more conservative figure than the 100W RMS number. The 100W figure appears in the manufacturer's own specification language, while the 75W number shows up in a single retail listing. Treat the 100W rating as the design figure and the 75W as a conservative continuous rating.
The 50 Hz–20 kHz bandwidth is the headline for a ceiling speaker. The tradeoff is size: an 8" driver in a ported can is a substantial box, and the C8.2HC is not a low-profile speaker. Electro-Voice makes the EVID C8.2LP for installations where ceiling depth is tight, and that model trades bass extension for a shallower can.
Historical Context
The EVID C8.2HC belongs to Electro-Voice's EVID Ceiling series, a line of installation loudspeakers built for commercial distributed audio. It holds the high-ceiling slot in that family, the model you specify when the ceiling is high and the room is a reverberant barn of a space. Electro-Voice's own documentation names airports, shopping malls, and convention centers as the target environments. In these rooms speech intelligibility is a code requirement, and a speaker that cannot control its dispersion turns every announcement into a wash of reflected sound.
The model carries part number F.01U.117.588 and a second part number, 301262000. A second-generation version, the EVID-C8.2HC-G2, followed with a revised transformer tap set and what Electro-Voice describes as "elevated SPL performance, extended power handling." No production years for either model appear in the available documentation, so dating a used unit means checking the part number and the transformer tap label rather than a serial-range chart.
The C8.2HC's design brief was narrow: deliver clear music and speech in spaces with high ceilings. The waveguide, the ported back-can, and the transformer taps all serve that brief. It is not a hi-fi speaker and was never meant to be.
Collectibility & Value
The C8.2HC is a current-production commercial installation speaker, not a vintage collectible, and it should be evaluated as such. The listed MSRP is $721.00, and the speaker is sold as a pair, so that price buys two boxes, two tile bridges, two backing plate supports, two cutout templates, and one paint shield. At least one authorized Electro-Voice dealer lists the model as in stock, and a Los Angeles Craigslist listing has offered a new-in-box pair. The second-generation EVID-C8.2HC-G2 lists in the $409.00-$578.00 range, so buyers comparing the two should confirm which version a listing describes.
Service documentation exists: a service manual for the EVID C8.2HC is available as a PDF download. That is more than many commercial speakers offer, and it helps if a transformer or driver fails in a unit that is already installed. No common failures, no owner complaints, and no spare-parts availability information appear in the available documentation, so there is no known weak point to warn about. The manual page for the model carries a single user rating of 7.5 out of 10, a thin sample.
For anyone building a distributed audio system, the C8.2HC is a complete package that needs no additional mounting accessories for most ceiling types, and its transformer covers both 70/100 V and 8-ohm operation. The MSRP is not trivial, but the box count per room is lower than a wide-dispersion speaker would require.
