    Default Possible system inbalance

    I don't know what is going on with my system lately but since moving in to this new cottage and changing to Spendor S3/5R2's I am aware of a potential inbalance in the presentation. With all CD's I have listened to there is a huge cavernous space of air and acoutsic to the far right of the right hand speaker but there is no such thing to the left of the left hand speaker. This is rather annoying to say the least. Anyway, with this in mind, here is what I have checked:

    Swapped over the speakers - no change

    Swapped over the speaker cables - no change

    Swapped over all interconnects - no change

    Swapped over all preamp valves including the rectifiers - no change

    Swapped over all power amp signal valves - no change

    So far all I haven't done is swap over the EL34's and swap over the digital coax cable for another make. I am starting to think that it may well be the room that is causing this oddity.

    Any suggestions..?

    I've had a similar problem and it was the room, or rather the position of the speakers in the room. It did not occur with all speakers, just some. Moving the speakers resolved the problem.

    My room is not symmetrical on either side of the speakers, on one side is a plain wall, on the other a long alcove between 2 chimney breasts. Until I experienced it I would not have thought that this would make such a noticeable difference to the sound. When it was suggested to me as the cause I was sceptical. But I moved the speakers anyway and it was indeed the problem.

    Have you tried reversing phase on one of the speaker connections?

    No Ali I haven't. Macca, sounds familiar. My room is a very vague L shape in which there is more room behind me to the right than there is to my left. This is why I think it has to be the room. Also, I have never encountered a pair of speakers that are so directional ever before. The slightest movement of each speaker makes a huge difference.

    Maybe swap to some big Tannoys, they don't seem to care where you plonk them.

    Are your speakers quite tall? I only have the issue with tall speakers, 5 foot or so.

    Hell no mate, speakers are LS3/5a wannabee's on Atacama stands at around 24" tall. Stunning speakers by my own standards but very bloody picky.

    I had an imbalance in my room along with some boom on the bass. The speakers are very close to a Piano and also in the corner of the room. It was causing all sorts of issues. On the suggestions of STD305 (Steve) we added some foam to try and decouple the speakers from the stands a bit and I have put a few egg boxes in the troublesome corner. The balance is greatly improved and bass is much firmer.

    It's a PITA but with a few bits of information you can balance the room a bit better.

    A couple of pics to demonstrate.

    Obviously, once I've got everything right, I'll make much better looking bits

    Not very well it's the gaffers. I can do a somewhat legible "imagine" and a few very easy songs but I never fancied it too much. I'm a guitar man. Bass, lead and rythm, banjo. Play drums and took Cello in my formative years too.
