My negative comments were based on appearance only...and were intended to be funny.
@livinon2wheels Many Tekton models (not all) with the different color combinations look like some expression of modern art to me, quirky not ugly. Oddly, my spouse liked the look of the double impacts I had in the past (!!) though it was in my office room. She thought the array looked like a flower.
Beauty is in the eye of the beholder perhaps. For example, here is a guy sitting in front of some of the ugliest speakers on earth (in my eyes) saying that the look of Tekton speakers could be improved . Go figure.

Any thoughts on subs with serious infransonic output?
Rythmik F18, 18inch sealed servo sub or G25HP (dual opposed 15 inch, runner up)...Slamfest down to ~10 hz, but, very much a high fidelity sub without taking too much space or costing anything. I use a couple of these in a hybrid rig.

if your wallet or space is not an issue, ascendo from Germany should fit the ticket. The subs can get huge, infrasonic for days.
