Heco Aurora 1000 (audioholics review)

[Ukraineguy]

Seems like a very quick drop off in the low end, especially given the large drivers and cabinet space.

They don't do what the Polk r700s do on those low hits in Sara K Water Falls. Close but not as good.

Another crossover rebuild ahead.

The I-core coils used by Heco are quite good. If you want to replace the I-core coils, I would recommend I-core coils from Intertechnik or Tritec air coils.
BUT please note that the I-core coils in the signal path with their internal resistance influence the volume of the respective loudspeaker branch.
