All these Beautiful room treatments reminds me of a Past Form Member..........He had a Huge Basement, with Cardboard Room Treatments that looked like architecture pieces..............(Now what was his name????????????)   He posted in the Architecture section mainly......

It sounds more like Arthurs, who is still a member, frequenting here none too frequently.

I tried 2' x 4' x 6" bass traps ( http://www.readyacoustics.com/index.php?go=products.proddetails&prod=RT426B --- plus 3 Owens Corning 703 2" fiberglass panels per bag) in the corner above each speaker, each angled at 45 degrees toward the center of the room.  This didn't affect the liveness or width/depth of the soundstage but it made the listening sweet spot much wider, slightly taller and much less sensitive to changes in listening position.  Since my ceiling is 9' high I didn't have to rearrange the Jubs to set the bass traps directly on top of the horns toward the driver end; the traps are lightweight enough to do this.

Subsequent to the above results, I laid out floor covering--my floor is tile--which slightly damped the soundstage liveness but increased the vertical dimension of the image.  I haven't had a chance to try many other locations for the other two traps I've got but it seems like they do well down low on the left to balance the couch's damping on the right.  My wife could really hear a difference

 

Hey Chris

Sounds like you have made some good progress especially if your listening position isn't being as critical.

When you mention floor covering are you positioning some of them(sounds like you have since you mention an increase in image height being perceived) at what would be the mirror images of the speakers? Try it (pillows, etc... temporarily) if you haven't even if it is something you would maybe just move in and out of place when doing critical listening.

In the past I have benefited treating the mirror reflections of the speakers on the ceiling with KHorns and it might be worth trying with the Jubs also. This is where actually being able to do an ETC measurement of your room would really benefit you.

I really need to find the time to seriously reanalize my room since placeing the Jubs in there. I've moved some treatments around from when I had the Khorns but I need to get it done properly. I've just not been very concerned since things sound really good for my current room limitations.

The temporary floor coverings I used were old comforters that we use when watching DVDs.  They work very well as movable absorbers.  I also find that room furnishings work to diffuse sound - there is never a lack of things to be placed on level surfaces in this household, including the mantle, wall-mounted shelves, and bookcases.  The behind-the-sofa location on the right is now hosting a bass trap at a 45 degree angle along the baseboard.  The front of the sofas can be bare or covered with soft comforters to adjust reflectance/absorption.  It only takes a moment to rearrange these to devices to achieve many different combinations.  However, the only remaining issue is ceiling bounce.  In that respect, your ceiling rack looks very good indeed.  I'll need some time, however, to convince the boss that this is "the next thing to address."  However, the Jubs do pretty well without any real effort there.  I had a lot more ceiling and floor bounce issues with the Khorns, however.     

Thanks again,

Chris the rack is just for me to experiment with different things. In your case I would just treat the mirror reflections of the Jubs on the ceiling to cover the critical listening area at most if you decide to check it out more.

All of that sounds like alot of work !

For the best room treatments just use the one wife with 3 girlfriends, even 1 or 2 girlfriends is also an improvement to a room !

Or in your case just add 1 or 2 additional girlfriends to improve any room ! 

I think you will like and notice a huge difference  !

Regards,

Chris
