Has anyone here had any dealings with Tekton, particularly their subwoofers

Op glad to see you back. 

@jayctoy Hey thanks for that Jay.

I have read this entire thread and considered advice given by those that were kind enough to respond to my questions. I also spent quite a bit of time on Tekton's website looking at their various models and my sense of their product line, after reading responses here and looking at their offerings, is that their real forte, pardon the pun, is LOUDspeakers, with an emphasis on high efficiency much more than wide bandwidth. Not saying that is wrong, as there are certainly benefits to that approach, but it doesn't line up for me as the right place to draw the line for home audio speakers. Granted this is my opinion and for those that draw the line that represents the trade-off between bandwidth and efficiency in a different place, that's fine, there is room in this pursuit of great sound for as many different approaches as there are people on the planet. I prefer to trade some efficiency for bandwidth, knowing that the extra cost in amplifier power to make up the difference is the price paid for that choice. Since the system I am ultimately building must serve dual purpose, that is, movie/tv and music too, even with full range speakers for LF and RF, I will still want/need a subwoofer or two or more for LFE while watching movies. That said, I was attracted to tekton's subs due to their high efficiency until one person's comment indicated there was not much output below 30 Hz. I am looking for real serious infra-sonic output and support for a true full range system. I am giving serious consideration to SVS's new 17" sub as the answer for that. It certainly gets rave reviews and if its a step up (as it seems to be) from their very good PC2000 Pros then I am likely all in. Other considerations are PSA 18" or 21 IPAL and monoprice. I have some time before this decision needs to be made but giving it serious thought beforehand seems prudent. Any thoughts on subs with serious infransonic output?

OP good luck on your search. BTW before you start trashing a speaker brand maybe you should listen to it first. 

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.

@livinon2wheels 

Also from Germany is Geithain, which is an extremely well regarded audio brand in Europe. Ex-GDR, been around forever, very old school. Here are their subwoofers. They’re cardioid, so less likely to suffer boundary interference response issues therefore easier to place and get right.

Geithain has no distribution / service in the US and word is that it’s kind of a labor of love to get their speakers over here, although some folks successfully have.

Good luck with your search!
