Remove rack or console from between your speakers


Several people have suggested removing components from between the  speakers to add a reflecting surface. If I did this my speaker cables would be as long as 18feet.  Would this degrade the signal much?

Mr. Miller,

Nice system setup.  Puts my wobbly (like the owner) wooden rack to great shame.

I like the insulators supporting the cabling.  Never thought of that considering I have several hundred.

Victor, Locke or Lapp, by chance?  Can’t see any markings.

Yeah I would have to look. The big ones are Cable Elevators which turn out to be standard ceramic insulators with a sticker. The smaller ones are various bought off eBay once I compared and realized they are just as good and a lot cheaper. 

You should see it now. Tweaks galore. But a lot is developmental and I am under orders not to divulge. So no pics. No reviews. Which is killing me. Well not really. The sound is to die for. I just can't describe it. Literally. 

Suffice to say I believe now more than ever what mahgister says about tweaking the "embeddings" (acoustic, vibration, electric) being more effective and important than upgrading components.
For many, having the rack between the speakers makes the most sense. You should however make sure the front of your speakers are at least a few inches forward of the rack itself to reduce high frequency reflection/diffraction.
So your ears were happy BEFORE you were made aware? Those weirdo audio friends of yours are inducing audio neurosis.


If your system is in a living space-normal furniture, family,pets etc...maximizing the working area you can position the speakers may be the way to go. Then, relax and enjoy music.

Other than a dedicated space to get the speakers out in the room is a compromise. The rack in the center, isn't so much of a deal with speakers out in the room. Even the coffee table in front of your sofa is a deal killer.

Trust your ears.


Right. Everything flat reflects sound like a mirror. From the beginning when I had nothing, no rack no turntable just speakers, a little Kenwood integrated sitting between them, even then I started noticing. Anything at all in the center reflects and makes the image less solid. Even one record album, I found out by accident when someone came over and noticed. Did not know why, just noticed the change in sound. I heard it too. Only after he left I figured out it was one record left out, my weak attempt at decorating an otherwise empty room. So I put this record out like art. Ruined the sound stage. One record.

Another time I got a great big tube trap in trade. Which is how I know these are not what they're cracked up to be. But whatever. To each his own. One thing I tried, dead center right in front of the components. Sounded like Sinatra was somehow singing from inside the tube trap. That probably sounds bad. I don't mean muffled like actually inside. I mean like no tube trap but instead Sinatra where the tube trap is. So it was good. Not for what everyone thinks trapping bass. It was good for this. Except for the part about it being the ugliest most inconvenient thing ever, it might be there today. Instead of hanging in the shop over my table saw. Works absolutely great over the table saw!

A few inches applies to frequency response. Even a few inches relative to a large flat surface like a wall makes a very noticeable effect in response. So there's that. But the rack thing, here its something different. Here its arrival times. What you're trying to do is avoid sounds arriving too close in time to the main L/R signal. You also don't want sounds arriving too close in location to the sound stage, at least not unless they are delayed a lot in time. 

We're talking 3 to 5 milliseconds. I'm going by memory, it could be 5 to 7 ms, but its something like that. Duke is the man on this. Anyway sound travels roughly 1 foot per millisecond. That's not precise, that's back of the envelope, which is good enough. First reflections within that time frame crush the image illusion effect. That's why everyone says put speakers at least 3 feet out from a wall. Makes the sound travel an extra 5 feet or so, pushes the reflection outside the 3 to 5 ms delay, sound stage is great.

Yeah, science!
