No, I don't think that's normal. There's nothing hooked up to the speakers at all, and you can hear hum?

+1... I've heard amps whine or whistle through speakers when they dissipate power while shutting down, but never heard a speaker hum for a few days... especially without being connected. Strange voodoo going on.

Not just hum, I've heard a woofer picking up things a few times when everything was turned off and figured it must be normal. Very faint, but either music, or talking. I remember mentioning it to Bwaslo when he was at my house and he thought I was crazy. I think he said maybe it was a high efficiency woofer that was picking something up, but still said I was crazy.

I have an old house and thought all the wiring may not be grounded right and something is getting picked up and pushed through to the speakers. But I'm 100% sure I heard the Cheap Thrills speaker picking something up even when it wasn't wired up to anything. That used a 15" Celestion and I believe the first time I heard it.

About 15 years ago I had a really old customer that said there was a local AM radio station that had such a powerful antenna (700 WLW) that you could hear what they were pumping out through different things in your house. He said something about hearing it through metal fencing somehow, but can't remember how. I just said "wow". He said they were eventually forced to cut back on the power due to complaints. He was an engineer that retired from GE, so I didn't doubt him.

Great thanks.... At least I don't have to call an exorcist now

Yep completely weird..... I had them unplugged for a day or two (I think) and had to move the speakers so my ear was quite close to the mids. I could hear like a faint hum quite similar to an amp hum. I must try and plug them out again tonight and see if I can hear it.

If you can hear it this time, short the input and see if it goes away. Just curious.

But, my first impression......VERY GOOD.
Just checking in to see if you were able to compare them to the Salks... just curious.

I finally made a trim ring for the woofers.

I see potential for a design here. A haunted speaker! Ghosts!

Thanks. I used a CNC and Sintra plastic. It isn't cheap material but the fake Sintra is not as good. I looks even better with a black baffle. You can see the Fusion max with trim rings at impulseaudio.ca with a black cab. Looks wayyyy better than the foam gasket.

Looks great ^

You own a CNC ? I did not know that. At any rate I really like it. Well done.

Is the plastic that thin or are you creating a recess bigger than the speaker for it to sit in?

Its 1/4" thick. I remove the foam gasket from the woofers. The trim ring is machined to allow for the lip on the woofer frame (3/16th inch thick on the circumference) and picket some holes to allow the screws to clear.

Ill get more info but I'd like to make them available to people.

Maybe it's an optical illusion but is the ring flat or does it have a concave shape to it?

@tuxedocivic I've been going back and forth recently between ported 893 towers vs 1099s on stands to use with my 893 center. Although they are a similar design and use the same CD, would there be any voicing differences if I go with the 1099s as L&R paired with the 893 center? I know there's a sensitivity difference, but curious as to sound differences... if any. I was thinking of going with the 1099s and their flat pack instead of building the ported towers for the 893s. Just curious as to your thoughts...
