"I had the same experience. As far as I could tell the NoFerro is a Seas 27TDF without the ferrofluid. The 27TDF is also hard to find in the US as it's been replaced by the 27TDFC. I used the 27TDFC with the WG-148 and was happy with the result. I ended up with LR4 acoustic @ 2500 Hz for the tweeter xover.
PS - The 27TDFC has ferrofluid."
