how can I make the back wall transparent?

WALL GONE!

Wow - I was expecting much more trouble than this - I'm beginning to love these speakers. Talk about forgiving!

I only had to move them a few inches back and the sound stage front to back became much more pronounced. Previously everything was behind the speakers. With the new placement the main artist is further forward but not in front of them. The rest of the sound stage is nicely spaced backwards.

Fortunately, those nasty standing waves seemed to have stayed away, so no need for any traps.

Toe-in is best at about one inch over the depth of the speaker (15 inches). More than that and the sound stage starts to close in :-)

The clarity also has improved a lot - even outside the room the sound is amazing and crystal clear

Thanks for all the input - this was the last part of the puzzle that had eluded me.

Now for some serious listening:-)

Wow. This is a great thread. I am going to try the rolls of, sshh, tp. It will be less expensive than real traps or others and I can change the design anytime I want. Wow!! I can paint them the rainbow colors if I want to. Oh now I am getting excited!! Ok now, I have an important question before I go on this journey of no return. How high can I stack them? And does anybody have any specs or ideas on what to expect its effect on the sound will be? And what brand should I use? Yes I will be using brand new rolls if you were wondering.

Charmin! and for best effect hang them on a rope - multi coloured will be high on WAF scale - you can even hang some on the wife/girlfriend and tell them its the latest fashion :-)

I like the hang on the rope idea. Easier to borrow some if you run out in the you know---. I should of guessed 'Charmin' because that is the way I want my system to sound. And by the way that little 'Charmin' doll should try out for American Idol I think. Good one Willie.

In the early 70's my band rented a house and nailed mattresses (back when you could get mattresses cheap at Goodwill) to plywood sheets on the basement walls and ceiling...possibly the ugliest good idea ever. (insert "Yo Mama" joke here).
