Description
Description
More diaphragm, more presence
The SP 8CM captures the spirit of the best-seller in a 20 cm format: a high sensitivity of 97 dB, a 31 oz ferrite motor, a 38.5 mm EISV voice coil, and a massive aluminum phase plug.
Highlights
High sound level with little power. On a 150 W channel, the efficiency already allows for a lot of presence in the cabin.
It helps maintain a clean off-axis response and helps dissipate heat from the voice coil.
Glass fiber-reinforced pressed paper, painted black, to maintain its shape as the level increases.
More body in the mid-bass and more presence than a 16.5 cm model, at the same power.
Description
The SP 8CM is a 20 cm mid-range speaker designed to produce a powerful, lively, and detailed reproduction. Its large diaphragm surface enhances the body of the mid-bass under the voices, without requiring more power from the amplifier.
Available at Sound Auto Concept, this model prioritizes measured values and real continuous power: 150 W RMS per speaker at 4 Ohm, for 300 W peak. It is sold exclusively as a pair.
- Rated diameter: 200 mm / 8 inches
- 38.5 mm EISV voice coil
