Room treatments

Randy-11

ASC was at the show so I would assume they helped treat them, but I do not know for sure.

Also, to the OP, contact GIK for advice. Super nice people, great range of affordable products.

So, if I may add, my working hypothesis was one of two:

1. I was having a stroke.
2. Those tube traps were reflective at the HF, and very absorptive in the midrange.

None of the GIK gear I use has these features. They are pretty much mid to treble, and sometimes also bass absorbers.

I think the ASC tube trap design is a mix no? Partly diffusor/reflector + partly absorptive?

Assuming ASC isn't just a horrible brand, I would then say perhaps the wrong mix of products was employed.

Hi Folkfreak,

Well, it is also possible I was hearing the electronics, but interestingly, I've heard Pass before, and not thrilled, but also didn't cause this problem.

This was the first show I have ever been to so meticulously treated by ASC. And room after room I heard a unique situation. Rather, I've never been to a show where all rooms sounded the same. It was truly odd. An exaggerated treble, along with this weird, 1 note bass. Well treated rooms sound huge, expansive, as if anything can be played.  These rooms, even among hotel rooms, were truly funky to listen to for me.

The correlation I found was : More treatment --> more problems. The most treated rooms, the Von Schweikert, Martin Logan, and a couple of others had the most problems. The Vienna with just two corner tubes sounded among the better situation.

I spent a day listening to several rooms at the California Audio Show treated extensively with ASC tube traps.

The more treated, the more suck. Not an innuendo. They literally sucked the midrange out of the room, turned the bass into 1 note, and added treble glare.

I live with GIK, they do no such things.  These CAS rooms were awful.

And, shocked the hell out of me since their peeps are really knowledgeable and of course, the products are so expensive.

I used to think of GIK as the poor person's ASC, but between the improved effectiveness of the soffit traps, and the experience at the show this has utterly changed.

@gdhal is right. It's not that Sonex doesn't do ANYTHING. It's just relatively ineffective compared to the average panel from GIK.

I also have to say, having had a chance to hear rooms heavily treated with ASC products, GIK makes a superior product, for far less cost.

Best,
