Re: Klipschorns and Room Treatments

I'd do the 4 corners all vertically and straddling.

Having one edge of the Monster off the wall a few inches won't hurt at all.

Re: Klipschorns and Room Treatments

I have my answer.

I just played the opening scene of Cars on Blu Ray (uncompressed PCM).

NEVER has that Velodyne sub sounded like THAT before.

Amazing, simply amazing...

Great job GIK!

But of course, you knew that already

Re: Klipschorns and Room Treatments

Outstanding. Glad they're working well for you. It's so hard to explain what it can do when you control the bottom end and you actually end up with more, deeper, and cleaner bass. Once you hear it though - you're hooked.

Re: Klipschorns and Room Treatments

I think I am going to cut one of the 48" original ones down to 42" tomorrow and put it in the 4th corner on top of the other rear K'horn - that will get all corners done the same. Looks like it is do-able and would be easier (for me) than flying two at ceiling level. Plus, it would look better and I can easily fill the corner space with loose pink stuff. The remaining original one will stay on the stand in front of the fireplace.

Even my wife noticed the difference last night (which is saying a lot) on network TV shows. Vocals and speech are firmly locked to the center like never before with less "chestiness" as others have described.

The room is definately deader in mid/high freqs now. Either I have over done it with the wall mounted first reflection panels or I just need to get used to it. Also need to re-run Audyssey and let it adjust to the additional absorption.

Hope to have time to post some "after" plots tomorrow.

Re: Klipschorns and Room Treatments

Before you go trying to cut things up, try mounting it horizontally and straddling the wall/ceiling junction.

Re: Klipschorns and Room Treatments

OK, I will try that with the two 48" ones and use the 3rd 42" one in front of the fireplace on one of the stands. I have some large black "L" brackets that I can mount on the side walls to secure the bottom of the traps & then tie them off at the top.

I tried putting them horizontally on top of the rear K'horns when I first got them, but did not like the look. Won't be as noticeable at the ceiling.

Re: Klipschorns and Room Treatments

Good. It's just almost impossible to redo these to a different size due to the construction. If you have to have them done, I'd prefer to do it at the factory.

Re: Klipschorns and Room Treatments

I was able to "escape" the office this afternoon and mounted the 48" Monster traps horizontally at ceiling level above the rear K'horns. The 42" traps are located as follows: 1 each on top of the L/R mains; the third is on a GIK stand in front of the fireplace, in the center of the rear wall, about 21" off the rear wall.

I could tell last night that "magic" had happened in the room with the additional traps. Here is the first "after" waterfall. Conditions are as follows:

Sub only; 80Hz crossover; Audyssey & BFD off, mic in center chair. Notice the significant reduction in ringing in the 50-60Hz range. The ringing around 100Hz may be a buzz in the suspended ceiling - gotta check on that...
