@buellrider97 has stated " I think the Tektons have quite a bit of cabinet resonance based on what I’ve experienced this past week as a new owner."
Based on your early experiences and shortness of a deliberation of the sound being produced, I suspect at present it is a condition met when in front of the Speakers that the source of the sound is able to be located by the ears.
The Box is adding a Sound that is not able to be unnoticed, or the Box is adding weight to a frequency that stands out for the locating of the source where the particular range of frequency is being produced.
To assist with taming a Cabinet Resonance, if resonance is noticeably present is able to done in certain cases with a Weight Placed on the Top of Speakers Cabinet. A 5Kg Dumb Bell, is a good start to lay on the Speakers Top Face. This can be moved around in 10mm to 20mm increments.
When the area is discovered for the weight that had the most effect at tidying up the sound produced, add to the weight, to see if a further improvement to tidy up the sound is able to be produced. If added weight improves things, tweak the positioning of the weight as well.
When all is as good as can be, live with it for a period and then try out simple isolators to see what is being added or taken away.
