Question about Microlab speakers and speaker placement

post #1 of 3
Thread Starter 

Hello,

 

I own a pair of Microlab solo 6c speakers, very nice products...but :), I've just bought a pair of stands to go along with them (truly remarkable difference in audio quality) and thought about seeing how each speaker sounds separately.

To my surprise the left speaker doesn't have the same bass response as the right one. It is true that the right one is near the corner of the room and as a result has walls to its side and back, but does this make such a difference ?

I also listened to them with this test http://www.youtube.com/watch?v=H-iCZElJ8m0 and I can clearly hear a difference in volume at around the 50-100+ Hz mark. After that they sound pretty similar.

Is this a problem with the speaker ? Should I get it checked ? The problem speaker is also the one with the amplifier as this is an active speaker system.

 

Thanks.

OK this is just me thinking out loud, I am pretty sure in these speakers the amplification is all in one speaker, the 2nd one being driven passively. IF THIS IS TRUE  then the internal dimensions of one will be smaller than the other and the power distribution between the main drivers may also not be equal which could lead to this issue.  I think the main issue will be the space taken up by the amp and electronics inside the main speaker, I am pretty sure they wouldn't make the slave speaker have the same internal volume to match the pair.  In higher end active speakers each cabinet will have its own amplifier or indeed a amp for each driver.  You would then manually balance the levels manually, and independently.

 

Placement can also play a part and sound reflections from side or rear walls can alter how they sound, what you can do is mark the position of your speakers and then swap their locations as accurately as possible and see if the imbalance moves with the speakers or whether its location related.

 

Step one is check its the speaker and not the room, after that its time to think about how much it bothers you :D

Placing a speaker in a corner tends to boost the bass response by ~6dB, almost twice as loud.

 

In this example a 'corner' is any edge. So if your speaker is in a real corner it might have a bass boost of up to 18dB because each axis is a 'corner'.
