Just finished building my new Selah speakers. As you can see from these pictures
http://www.audiocircle.com/index.php?topic=102460.0
They are as far out into the room that I can get them. Would it be of any benefit
to provide  a few 2 foot high absorb panels behind the speakers? mini corner bass traps?
Will this this be any help at all?
I am just getting started evaluating the room acoustics, but not having the speakers pulled out into the room seems likely to cause problems.
Thanks.

WAF issues?

A friend built a really big/nice home of his own design (he acted as general contractor).  Really poured his life into it for years, but forgot to check with his wife.   

As they had to smaller children and there was a large pond immediately behind it, she refused to move in with him.  The sounding gong, the last straw, they divorced.   

Have you considered locking casters in place of the spikes to facilitate easy movement with a 2 setting DEQ for his/her speaker positions?  I'd make any treatment selections based on optimal location and just laugh off/keep turned down the system in the "her" position.

They look great!

That's not necessarily the ideal place for speakers. The best way to find where you'll get the smoothest LF response is to measure at high resolution using room testing software such as Room EQ Wizard.

Any bass trapping is better than none, but in reality you need more than two small traps to get good sound in most rooms. You'll find some Before / After graphs with explanations here:

Ethan, shouldn't your post be in the Industry section since you are selling something on your link?  At the very least, I think you shoud indicate that you have a vested interest in your recommendation.  Any other manufacturer would get slapped on the wrist or worse.  it's only fair that you play by the same rules as everyone else. 

Right?

Thanks for the information
WAF: gotta love it. Don't think I can afford to give up 1/2, so the speakers stay back. Overtime I will inch them out into the room. They are not truly "spiked, so they slide easy.

I will look closer at the room EQ program. My subs do have a parametric equalizer, so I may be able to make a few changes. I have an iPad spectrum analyzer that may help a little.

Ethan, Proper forum or not, I do appreciate the advice. And also appreciate the advice of any circle members. There is a lot of experience out there.
With placement limitations, the small three walled area behind each sub, a little acoustic on all three walls? Even if it is not great benefit, I will take anything I can get.

Thanks again

I'm not sure if active EQ will help your situation.  You night want to look at some custom platforms with locking castors that will allow you to pull the speakers out for critical listening and put them back against the wall when you are done.  I have to think they would be boomy and not image well when placed so close to the wall. 

It's a shame because they are beautiful speakers and I'm sure they would sound great with decent positioning.  I playee around a lot with placemt of my speakers and they sound so much better away from the rear walls with a bit of toe in.

Good luck!

You really need to see the LF response at high resolution in order to optimize speaker placement and acoustic treatment.

A little is better than none. Without knowing anything about your room or even seeing a photo it's impossible to advise you. But the Acoustics Basics article I linked earlier explains the general goals.

Ethan,
On the first post in the conversation, there is a picture of the set-up, if you would be so kind to take a look.
Thanks

Well,
I think the plan will be speakers out when listening to or watching music DVD's, then speakers back when not.
I will still work on setting the sub parametric equalizer when they are in listening position. I will probably put a little sound dampening back there, just cuz I want to, (gotta win some battles once in a while) The rest of the room is probably an acoustical nightmare.
Thanks
Just getting the rest of the system set up. Mac mini and Calyx DAC to replace Bolder squeezebox 3.
I will check back in when I develop more questions and problems.

It would help to be able to see more of the room in context, including the sides and rear, rather than only part of the front. But I still suggest measuring the room if possible, because that's the only way to really know how placement affects the response. At the minimum, a few bass traps will surely help, as well as absorption at the reflection points. You'd also do well to move the center speaker out of that high alcove, and put it in a small stand under the TV.
