Lack of depth problem


Can someone please give me suggestions on how I can improve the sound depth of my system? I recently upgraded my speakers to Focal JMLabs Alto Utopia, but they still lack of depth. They have wide and tall sound stage though.

The room is about 15' wide by 9' tall, and 23' long. The speakers are 5' from their rear wall and the seating area is 17' from that wall. The room is lightly treated with sound panels.

Thanks in advance.

Agree with Newbee. Check out the Cardas site. Use simple (one/few performers, acoustic instruments, NOT multitracked heavily mixed rock), analog recordings (NOT digital) for optimizing. A good starting point for your speakers should be between 5'-9" and 7'-8" from the wall behind the speakers. Try to have as much room between the speakers as possible leaving a few feet on either sides (your room is narrow). Using a string make sure the distance from both speaker to your listening position is equal. Do not toe-in the speakers initially. Simply start at one distance from the back wall and move them 1" at a time until you have optimised the location. Once there, use smaller increments. Use minimal toe-in until the image "snaps" into focus. Always try one position and compare the sound with the previous position. Listen to the "accuracy" of the bass, naturalness of vocals, and other instruments.

This is a long, tedius process and can take several months to get right. Enjoy.
On what basis are you making the judgment that your setup lacks image depth? What are you listening to that you know images deeper, but isn't happening on your current system?
I should have mentioned in my previous post that there are two tests that will aid you specifically in the placement of your speakers(on the Chesky disc). The LEDR, explained here: (http://www.stereophile.com/features/772/index.html) and the "Acoustic Soundstage (Depth) Test".
Vett93,

Besides the speakers, did you make any other chages to the system? What type of speakers did you have before?
