Love my new SRS-XB2 but in dual unit mode the signal is out of phase.

I am a 30 year career professional audio engineer.

I selected the SRS-XB2 after auditioning many other units in a department store that had about 10 different models. I used to have Bose Soundlink 2 but the rediculous amount of bass on the unit annoyed me.

After getting one unit home I decided to order a 2nd one to take advantage of the dual unit stereo mode.

However its instantly apparent that when using 2 units in stereo the L & right signals are reverse phased, leading to cancellation of almost all centralised bass signal and an unatractive sounding mid frequency reproduction

When listenting to pop / rock or dance music productions - the kick drum (bass drum) and bass are typically centrally located in the stereo field or 'panorama'. In a correctly phased stereo set up, bass signal from the left and right speaker combined should be additive (ie centrally panned signals should combine 50/50 to make up 100% volume) you should clearly be able to hear the kick drum in the middle and the bass instruments also.

But listening with your head in between two equally spaced SRS-XB2 units, there is no such low end signal additive combination (it is clearly subtractive or "bass light") and mid frequency signals exhibit the classic 'eriee / 'behind you' sound that an out of phase stereo speaker set up typically gives you.

On a wired speaker set up this would be remedied by swapping the + /- speaker cables on ONE speaker to put them "in phase"

Its a shame that such a cool product suffers from this fundimental problem.

Would the moderators product evangelists here kindly please test this and bring it to the attention of Sony engineers please?

I would like to have a pair of SRS-XB2's that are correctly in phase.

(I suspect the rear facing bass units are the culprits, they may need to be "phase flipped"

Many thanks,

Hi there

I cannot test this as I do not have this product (never mind two of them) - However even though if I could confirm your findings there would be nothing I could do about it.

However, I am escalating your post to Sony Support for them to investigate and find a solution. They may contact you for further information.

Cheers
