REVEL performa3 f208 or TEKTON Moab

Only smaller gauge inductors appear to be targeted at the upper frequency where there already appears to be resistors for level matching so the largest gauge really does not matter. The low frequency inductors are not air core for the intentional reason to reduce DC resistance.

rikkitik8 posts12-15-2020 4:58pmThe 208 uses small guage, high dcr coils, and iirc, at least one electrolytic in the signal path

the steep slopes and poor crossover components kill the F208. The moab uses 6 db slopes which is phase coherent and features an upgrade for crossover components.  

This is a really old article, and still relevant and covers this false notion about the perfection of 6db crossovers...

David Wilson, Richard Vandersteen and John Dunlavy wouldn't agree with that article. Nelson Pass designs nice amps, but not loudspeakers.  

Physics and electrical engineering does not change suddenly because you don't own a speaker company. I don't own a speaker company, but I likely know far more about truly advanced active speaker design than David, Richard and John combined.

Pass has done extensive measurements with his amplifiers driving real speakers, so his body of knowledge extends well beyond just the terminals on the back of his amplifiers.
