Loudspeaker Crossover Inductors
* Ferrite Bobbins
Ferrite Core Bobbins.
Four sizes of Ferrite Core Bobbins suitable for
winding custom value Inductors as used in loudspeaker crossovers.
Designated as Type A through to D.
A 'guide' to usage is
as follows:-
Type A: FBA1823 Small value Inductors for Tweeter
frequency modifications / tweeks.
Type B: FBB2728 Low power Bass
and Tweeter crossovers to 50w rms max. system power.
Type C:
FBC2535 Medium power Bass and Tweeter crossovers to 80w rms max.
system power.
Type D: FBD3040 Medium power Bass and Tweeter
crossovers to 100w rms max. system power.
NOTE: All DCR values are calculated values based upon wire length and diameter.
* Ferrite Core Bobbins. All dims mm are approximate
