What affects timing in a system?


I got a new pair of speaker stands for my MG3.6 and was surprised with the result. When I first put them in, the bass was so much better, but the rest of the fine balance was way off. I had to adjust speaker placement to fix soundstage and high frequency response. Replace isolation products from...etc. Now I feel that I have all the parts the way they should be timbre, dynamics, detail without fatigue etc.

The problem is every thing sounds slower and just off in timing. My girlfriend who has better ears than me says the music has "lost it's rhythm". HOW CAN THIS BE? I didin't add any electronics that would change phase response or electrical transmission. I don't know what to check/change/tweak? Any advice, experience, or guesses?

Since bass is the "foundation" of music ( drums and bass are the "rhthym section" of a band ), "tightening" or "thinning" of the lower frequencies will almost always reduce the "pace" of a system. That is, unless it was bloated to begin with. While the rest of the frequency range might sound sharper, more defined, etc.., losing tempo will almost always result in a system that just seems lacking and less "musical". Since everything else seems "right", it is sometimes hard to put a finger on exactly what is different.

My guess is that you now have a hole somewhere in the lower mid to bass region and this is what is robbing the apparent energy away from the music. Changing speaker elevation will ALWAYS alter the in-room frequency response. I would suggest using an SPL meter to take a look at the appr. frequency response of the system as it is now and then take readings with everything back to how you previously had it set up. While i know this might be a LOT of work, it will probably show you exactly what is different across the frequency range.

Doing something like this BEFORE making changes will document the exact results of any relocation or component swaps. This allows you to compare "before and after" data and can result in a more progressive flow towards beneficial system upgrades instead of "i'm not sure what happened" or "i THINK it helped" type of situations.
