@rauliruegas I get it. But…I’m enjoying the music with my system and I do not hear IMD. Neither do I need to obsess over it because…
According to Wilson Audio…
The tweeter is isolated internally from the midrange and woofer drivers with the latter two transducers sharing the same internal volume. Wilson Audio notes that in this configuration any potential for intermodulation distortion is minimized by prudent driver selection and precise porting of the enclosure.
This sounds like truth as I cannot detect any distortion. The drivers cross over seamlessly.
I’m very thorough when it comes to my system but I think we’re attempting to shoot down a fly with a bazooka here…
By the way I looked at your system page and I’m very impressed! Gorgeous system and some collection of cartridges you got there…enjoy!
