Fi Drivers Link

Drivers are discounted $20ea when 4 or more are purchased. Shipping is not included in the price.

When you order drivers from Fi please mention you were referred from the "Cult" forum

[noviygera]

Any chance of getting the inductance (Le) values for those IB3 drivers?

Thanks,
Herman

[ThomasW]

Probably want to ask Fi directly

IIRC when ask they've said that info wasn't available, but you can certainly ask them again

[ironglen]

Any Cult discount available for a pair?

[ThomasW]

Discounts are for purchases of 4 or more

[tkeslinky]

How do we go about getting the discount? I'm ready to pull the trigger on 4 of the IB318's. Had to wait for the new website to be up...I guess I thought it would be applied automatically. Is the discount still available? Thanks.

[ThomasW]

They're on sale for 15% off, that's $25/driver less than the $300 ea 4 driver discount price

[tkeslinky]

I'll get them ordered then. They have free shipping as a special for black Friday as well...
