No.@antcollinet a little sideways on the topic. I have a McIntosh MC500 power amp that will push 500 watts to each channel at 8 ohms. It will also do 4, and 16 ohms.
My Celection Diton 66 towers are only rated 160 watts at 8 ohms. I never drive them hard and I have all this overhead. Would there be any advantage to running this 4 ohms? Thanks.
But this was a one time only demonstration, so if he had rehearsed he wouldn't have been able to do the actual demonstration.
Ditton 66 impedance is specified as 4 ohm minimum, so do connect them to the 4-ohm amp output.@antcollinet a little sideways on the topic. I have a McIntosh MC500 power amp that will push 500 watts to each channel at 8 ohms. It will also do 4, and 16 ohms.

Right. When set to "small" the bass is re-directed to the subwoofer.I may have made was having the speakers set to Large in the Denon setup as I believe that means full range of frequency was sent to the Wharfedale EVO 4.2
That's reasonable. It's hard to get any kind of service these days. And it's important to use the right woofer because the cabinet and woofer are optimized to work together. This is especially true for a ported speaker. And the output is matched to the midrange & tweeter and the crossover may have some tweaks/tuning to optimize that particular woofer.They are offering to sell me replacement woofers for $99 each +shipping.
I've never seen that done but filtering might built-into active speakers.Aren't ported speakers suppoused to be high-passed below the port frequency to avoid exactly this?
The output options of the MC500 selects a transformer to adapt the voltage/current output of the amp to the speaker impdedance.@antcollinet a little sideways on the topic. I have a McIntosh MC500 power amp that will push 500 watts to each channel at 8 ohms. It will also do 4, and 16 ohms.

ith an AVR set for "small" speakers it doesn't matter if they are ported or not.
Ahh, really? Are you serious? Are you one of those that would dry your wet dog in the microwave oven if it wasn't warned against in the manual?I believe that if manufacturers don't implement a high pass filter, then I'm not responsible if the woofer smokes with 20 Hz signal, because not all audio devices have one.

he said it wasn't extremly loud. also beeing a Youtube video there weren't any signals close to 0dBFS.
I am just wondering it could possibly a design failure, not user error?
A 10 second continuous sine wave below the port tuning is a very different scenario than normal music
But I was really paying attention for any mechanical noises or overtones. Overtones are easy to hear with 20Hz test tones--If you can hear the tone at all above a muted felt vibration, it's probably an overtone you are hearing.
Bi-wiring and passive avr bi-amping are more a waste of wire. It shouldn't hurt, it just has no particular benefit. More about marketing. Setting to small and using a crossover is something you should have done from the start, tho....live and learn!Original poster here: Thank you everyone for the discussion. I have learned a lot. Definitely no interest in watching test tone videos in the future. As I mentioned, one of my guests said to try it and 10 seconds later I have smoke. I have already adjusted the speakers to Small and set the crossover to 80Hz for after I complete the repair.
One follow up question, is there any concerns about the Bi-Amping? Is that a potential cause as well or am I fine with this AVR and speaker, assuming of course I wired it correctly. Should I just Bi-Wire instead, or not bother at all?
