wow me and this dude have very similar tastes in gear and setup.

I have the same SV112 amp. the same Bass(diff color). although a different guitar.
and I even noticed the replacement pick guard for the bass under your desk and I was JUST looking for one in black today on ebay. I almost bought that desk too, but didn't like the upper shelf being as short as it was, or the black grated sides. I got a KK audio instead.
I gotta some pics damnit.

The reason to angle your speakers when they're placed on their side in not because bass sounds are mono, but because frequencies travel at different speeds through the air. The bass frequencies travel more slowly than the hi frequencies. So in order to have those frequencies reach your ears at the same time, you angle the speakers so that the bass has less distance to travel than the hi frequencies.

And it does make a difference, as Triple-X said.

wow...I don't know who told you that, but the speed of sound does not at all depend on frequency, at least not in air. Look it up on Wikipedia or something.

WTF are you talking about bro. Im sorry but you are clueless...the bass frequencies have WAY more strength then high hence the reason you hear a car with booming bass a block away and only when its close can you hear the highs. It isnt about the speed of the audio... Furthermore you place speakers on their sides to widen your stereo feild. Additionally what difference would the angle of the speakers make on travel time if they are both leaving from the same level surface...man there is so much wrong in your post its bad..please delete it.

??? If that's true; then I'm insane.

Because you can hear bass frequencies from further away does not have anything to do with the speed at which they oscillate or travel. It is possible that hi frequencies can be dampened over time, or distance, and that will factor into how far away you might be able to hear them from.

You do not place your speakers on their side to widen you stereo field. You place your speakers further apart from one another to widen your stereo field. Each speaker represents a single channel. the stereo field has nothing to do with the hi and low frequency relationship on a single channel.

"You're right, HF falls off faster than LF. It's a simple matter really, in that higher frequencies causes the molecules to vibrate more, so more acoustic energy is transformed into heat. One weird side effect is this same effect literally changes the speed of sound at HF by a tiny amount. This occurs more at sea level than it does at higher altitudes.

There are some other weird things that happen due to atmospheric conditions. In still air, sound is refracted upwards due to the fact that temperature at altitude is lower than it is at sea level, changing the speed of sound. Wind causes an opposite effect downstream, which causes refraction downwards. The combination of these effects can exactly counter, in which case sound will travel along the ground, seemingly in a straight line. Or it may appear to have a dead spot, where sound cannot be heard in some area between the source and another more distant area where it can again be heard. Or it may simply be refracted away. Depends on the wind speed and the temperature."

The relationship between hi and low frequencies is well documented. You should do a bit of research yourself. I wrote a paper for publication in a medical journal ("Musical Stimuli and it's Impact on Human Physiology") as the result of four years of research on audio vibrations at UMDNJ Medical School, regarding the physics of audio waves and how they impacted and affected human physiology.

I don't mean to criticize, or attract any more criticism, but I think it's unfortunate when people's main source of information is wikipedia.

yeah, i love their stuff, I also just finished a house track with a wicked Bar-kays sample on the break, what kind of music do you do?

ok I gotta chime in. I'm a physicist (well working on a masters right now) and have done extensive research in acoustics at the National Center for Physical Acoustics in Oxford, MS. As far as I know sound speed is not dependent on frequency in air except in very special cases. The effect you are talking about is EXTREMELY tiny and not going to factor in when placing your speakers 5 feet from your ears. Also when they're talking about HF, they're really talking about ultrasound. The second paragraph is talking about something completely unrelated that also happens over a long scale called diffraction (sound speed IS dependent on temperature). I didn't learn that from Wikipedia, I learned that from Kinsler & Frey, Pierce, and from three graduate courses in physical acoustics (physics not engineering).

Any besides that, put your monitors however you want, it really doesn't matter. Just learn how they sound in that position so you can have your mixes translate elsewhere.
