Start with the installation constraints
In commercial and corporate spaces, woofer size alone does not determine the right ceiling transducer. Available depth, access, programme material and cable routes also matter. The VIC8 family offers two installation configurations.
VIC8 has no integrated back-can; VIC8X includes a back-can and tile bridge. An enclosure makes rear loading more controlled, but does not provide complete room sound isolation.
Read the two models separately
This comparison follows the official manual linked below. Older documents contain different values; match the document revision to the supplied model.
| Property | VIC8 | VIC8X |
|---|---|---|
| 8 Ω power | 60 W RMS | 60 W RMS |
| 1 W / 1 m sensitivity | 90 dB | 93 dB |
| Effective range, −10 dB | 59 Hz–20 kHz | 75 Hz–20 kHz |
| Required depth | 120 mm | 200 mm |
| Recommended cut-out | 246 mm | 246 mm |
Nominal angle is not every-band coverage
A single nominal angle cannot describe every frequency band. In the AVASH tool, check frequency, data source, angle and overlap mode. A manually entered 90° angle is a design assumption, not a fixed specification for both models.
The plan shows geometric footprints. Verifying weak spots or a speech-intelligibility target requires directivity information, room effects and measurement. Enter the effective height and listening plane accurately.
A 12 × 8 m example with explicit assumptions
Consider a 12 × 8 m room, 3.5 m mounting height and 1.2 m ear height. With both angle inputs manually set to 90° and standard overlap selected, effective height and geometric radius are approximately 2.3 m.
For these explicit settings, the rectangular grid gives four columns and three rows: 12 positions. Actual spacing is 3 m along the length and about 2.67 m across the width. Other angles, frequencies, heights or patterns may change the result.
h = 3.5 − 1.2 = 2.3 m | r = 2.3 × tan(45°)From transformer taps to amplifier capacity
Twelve positions at 30 W give a 360 W load. The current placement tool adds 25% to that load and displays 450 W. This leaves 20% of amplifier capacity unused; it is not a universal mandatory reserve or a dynamic headroom specification.
The 30 W tap is an example, not a fixed recommendation for every lobby. Check target level, ambient noise, zone needs and cable losses. Use the line-load tool for an adjustable reserve; check low-impedance power and protection separately.
12 × 30 = 360 W | 360 × 1.25 = 450 W
