I have done a bit more subjective testing and I have found that our ears do increase the gain of frequencies in the 2k to 7kHz range as the source moves from 90 degrees toward the front of our heads however this gain reaches a peak at around 30-45 degrees (which corresponds to recommended...

Just ran a quick test with a few fixed frequencies. It is going to be complicated. Around 5kHz the sound does indeed decrease as it moves from front to side. 7kHz does the opposite. 11kHz has several nodes, one at an angle about where a speaker might be and another to the side, near 90 or more...

Interesting stuff! It will take me a while to sort this stuff out. It appears contrary in some ways to polar plots of hearing at various frequencies that I had seen as well as my own personal observations. More to learn! Thanks!!

Thanks for the link to that info. The one thing the mixer usually has going for him/her is that they are in an acoustically treated room with speakers/monitors placed in optimal positions and angles. What I was referring to is the fact that if you are sitting directly in front of a speaker at a...

It has been said that the proper spread for speakers is an equilateral triangle form by the listener position ang the two speakers. This would indicate a speaker spread of 60 degrees or 30 degrees to the left and right of center. Most say that spreading them further apart can deliver a wider...

I am currently waiting for the old one to die. I have a Sony SXRD KDS-R60XBR1 which I purchased around 2006. I occasionally put in a new lamp and had to replace a fan once. It still looks pretty good, nothing like the new tech but adequate resolution and good color for our viewing distance, out...

Will physically aligning horns for time alignment possibly cause complications at crossover frequencies due to the shape of the wavefront coming out of the two horns? Some horns have a flatter wavefront while others may be be more spherical…Can sliding the mouth of one horn with respect to...

I have old E/V Sentry IV horns. I have replaced the E/V tweeter with a Beyma slot tweeter. I have moved the tweeter from its original bracket mount below the midrange horn to a platform over the midrange horn that allows me to physically achieve time alignment with the midrange horn. I am...
