The coil, placed before a bass driver, is suitable for a power of up to: Watt
Important hints:
Dimensions refer to that part that gets as hot as the copper coil itself and, therefore, dissipates heat optimally. All values indicated are just a guidance and cannot be guaranteed. They were, however, results of around 100 long-term measurements over 24 hours each. The values are valid for coils with free air convection. If convection is perfect and temperature is 20°C the coil is able to transmit up to 50% more.

These values are only valid for core coils under the condition that they don't generate any additional heat through magnetisation loss (like with Corobar coils).

If two coils L1 and L2 are in parallel, then Lges = (L1 * L2) / (L1 + L2)

Coils in parallel Please enter decimal separator as "."
L1 = mH and L2 = mH   Lges = mH

If two coils L1 and L2 are in series, then their inductance is added up.

Coils in series Please enter decimal separator as "."
L1 = mH and L2 = mH   Lges = mH
