Can Electronics Affect Speaker Placement?


When I started out in audio five years ago, I experimented with speaker placement until I had a pretty good soundstage. A year ago I placed some bookcases along the walls to the right and behind the speakers, so I relocated the speakers to adjust to their new room boundaries. Within a four month span earlier this year, I replaced my amp, preamp and cd player, with noticeable improvement In the sound. I am also about fo replace my speaker cables. Does it make any sense to tinker further with speaker placement because of the new electronics and cables? I know that the dispersion pattern of the speakers and the interaction of particular sound wave frequencies with the room boundaries remain the same, but wonder if the stronger lower mid-range and upper base frequencies I now enjoy might be reason to further adjust the speakers’ placement. Of course, I could always experiment and find out, but any improvement might be due simply to improving the speaker placement regardless of the changes caused by the other equipment. Thanks for any responses.

Thanks for the reponses. I'll definitely experiment with the toe-in (no lifting) and some minor changes in location.
The short answer is yes. Different electronics can demand a different soundstage with changes in speaker location. Here is one example in an older thread. Cheers!

I think you can affect the tonal balance with speaker placement and that if you are hearing that big of a difference (i.e., the upgrades caused that much of a change in sound), then it may be worth playing with speaker placement. (of course, just changing the calendar over to a new day is excuse enough for some of us to tweak).

happy listening...
As you know every new component in a chain will result in a different system response. I think adjusting distance to rear wall and toeing the speakers in/out should suffice.
