ZSOUND CP Series: A Full Range Speaker Engineered for Conference Rooms, Churches and Fill Systems
Choosing the right full range speaker — one that reproduces the entire audible spectrum from a single enclosure, without needing a separate subwoofer for everyday content — is the most critical decision in speech-focused installations. The ZSOUND CP Series (CP8, CP10, CP12 and CP15) delivers exactly that: a passive two-way design with an 80°×80° constant directivity horn, tuned specifically for venues where vocal clarity matters more than raw bass output.
Why Constant Directivity Matters in a Full Range Speaker
Most loudspeakers spray high frequencies in unpredictable directions, causing hot spots at the front and dead zones at the back. The CP Series solves this with a constant directivity horn — a waveguide that maintains a consistent 80° horizontal by 80° vertical coverage pattern across the entire vocal range.
Think of it like a well-designed desk lamp: instead of a narrow spotlight that blinds one person and leaves others in shadow, it spreads an even wash of light across the whole desk. In a conference room or church, this means every seat hears the same intelligible speech, whether it is the front row or the back wall.
CP8 vs CP10 vs CP12 vs CP15: Which Full Range Speaker Fits Your Room?
The four models share the same design DNA — birch plywood enclosures, black polyurea coating and Neutrik NL4 connectors — but scale in size, power and low-frequency reach. The table below compares the key specifications:
| Model | Woofer | HF Driver | Power (AES) | Peak SPL | Frequency Response (±3 dB) | Weight | Best For |
|---|---|---|---|---|---|---|---|
| CP8 | 8″ | 1.75″ (44 mm VC) | 250 W | 123 dB | 90 Hz – 18 kHz | 9.8 kg | Small meeting rooms, fill |
| CP10 | 10″ | 3″ (75 mm VC) | 350 W | 127 dB | 55 Hz – 16 kHz | 18 kg | Medium conference rooms |
| CP12 | 12″ | 3″ (75 mm VC) | 450 W | 130 dB | 55 Hz – 16 kHz | 22 kg | Large halls, churches |
| CP15 | 15″ | 3″ (75 mm VC) | 500 W | 132 dB | 45 Hz – 16 kHz | 26 kg | Main PA in mid-size venues |
How to choose: The CP8 extends only to 90 Hz, so it relies on a subwoofer for music playback; the CP15 reaches 45 Hz, deep enough for most speech and light music without a sub. The CP12 and CP15 share the same 3-inch compression driver for detailed highs, while the CP8 uses a smaller 1.75-inch unit to keep the enclosure compact.
Vocal Performance: The 75 mm Voice Coil Advantage
A full range speaker lives or dies by its high-frequency driver. The CP10, CP12 and CP15 all use a 3-inch (75 mm voice coil) compression driver — significantly larger than the 1-inch drivers found in budget speakers.
A larger diaphragm moves more air with less effort, which translates to lower distortion at the frequencies where consonants and speech intelligibility live (2 kHz – 8 kHz). The result is a speaker that sounds relaxed even at high volume, without the harsh “shouty” character that makes audiences subconsciously lean back in their seats. Combined with a frequency response shaped to avoid auditory fatigue, the CP Series keeps listeners engaged through long services, lectures and presentations.
Installation Flexibility for System Integrators
Every CP Series enclosure includes multiple M8 flying points and a pole-mount socket, so the same inventory can be:
- Flown from ceiling or truss as main PA
- Pole-mounted over a subwoofer for a compact church system
- Wall-mounted as front-fill or delay speakers
- Angled on its side as a low-profile stage monitor
At 9.8 kg (CP8) to 26 kg (CP15), a single technician can rig a pair without a lift. The 80°×80° pattern works equally well in horizontal or vertical orientation — just rotate the horn to match the coverage to the room geometry.
Pairing with Subwoofers for Full-Range Music
While the CP12 and CP15 handle speech and light music on their own, venues that host live bands or playback-heavy events should add a subwoofer. The CP Series pairs naturally with the ZSOUND S12P active subwoofer, whose built-in three-channel DSP module can power two CP tops in a 2.1 configuration — no external amplifier rack required. For fixed installations, the passive S18BII offers 1,250 W AES of 18-inch low end in a compact vented enclosure.
A complete sound system is not only about what the audience hears, but also about what they see. If your project includes stage or architectural lighting, our partners at SeeStar Lighting offer fixtures that integrate cleanly with professional audio installations.
