Mystery with woofers. Help!

If the info I ran across is correct, that midbass crosses over to the woofer at 65 hz,so it’s actually producing all but the lowest frequencies of bass, which your sub is covering. If you ended up plugging the woofers back in, you may want to adjust the output of your sub.

There are pros and cons to every speaker design choice, but I’m a fan of those crossover points because it puts the whole vocal range in the midbass driver vs splitting it between the woofer and midrange driver. Nearly exactly how my speakers are designed.

p.s.: that crossover point is very conducive to bi-amping.  I'm running tube amps on the midbass and tweeters, and a SS integrated amp to the woofers...best of both worlds.  

Thanks everyone!!

@knotscott Interesting. I think you’re correct about the bass. The midbass was taking care of all but the lowest frequencies, and then crossed over to the sub. This explains how I missed the inactive woofers.

I texted with Dick Diamond of GTT Audio today. He is the former director of sales at YG. He also suggested that I consider bi-amping in the future. In the meantime, I’m excited to get some jumpers connected and hear what the Haileys will produce on their own.

I'd find some wire in my garage and make some temporary jumpers and be reporting back how the bass sounds by now.

Fair play for owning up.

I feel like an arse

This reminds me of the time I was at a friends house. He has small floorstanders and the woofers had ALOT of excursion. My Avior ii speakers don’t have very much excursion but give tremendous bass. I was curious about the difference so I asked Duke at audiokinesis and he said a woofer that moves a lot is trying to do too much and the sound quality will suffer. He did say that it’s not a design flaw when the woofer has that much movement though. Happy new year to all
