how can I make the back wall transparent?

YEs, I mean wall behind speakers opposite from listening position, which is the one in front of you when listening facing speakers.

You can use room acoustics or fight them. Both are valid approaches. Each might have a better chance of success depending on magnitude and nature of room acoustics. All rooms have a unique sound and best to first assess it then use it and tweak accordingly as needed IMHO.

So, If I understand you all correctly...
Other than the placement of furniture, rugs and the two screens that I have in place to dampen an echo behind the speakers and careful placement of the speakers to attain the best sound (to remove standing waves etc) and to derive the best imaging...

Additional and very precise adjustment of the speakers either further from or closer to the wall behind them, may result in the sound waves from the speakers becoming aligned in some way with the reflected sound waves resulting in a more cohesive image that appears to make the rear wall less apparent - correct ?

One thing I have noticed is that albums recorded in the studio is more prone to "the wall effect" whereas the venue acoustics of live performances tend to make the wall much less apparent.

If I only had a bigger room :-)

I'll give it a whirl and let you know how it pans out - many thanks

I think you've got it covered.

One thing worth adding is that you might have to adjust distance between speakers as well when you play with distance from front wall in order to maintain good imaging, including a strong center image in particular. Mono recordings are particularly useful for testing to see how well center imaging is doing. If center imaging works well for a mono recording, stereo recordings should benefit as well.

Its also worth noting that what works best for sound stage size and imaging may not be exactly the same setup that works best for flat frequency response top to bottom. I like to get the soundstage and imaging right first, then tweak from there as needed to get tonality right as needed. That might include wall treatments, or any of the usual suspects used to tweak sound quality from there.

Syntax,

That one was beyond funny :-))))))

Good Listening
