Four π and room interactions
The heat sink on the front of the Kilomax is one of the reasons I stopped using them. I love the idea of pole piece wicking, but don't much care for the idea of putting the heat sink in front of the cone. In fact, I have a patent applied for a pole piec...

Re: stereo subs vs all around the room subs
I agree with you about stereo subs. One of my favorite implementations is a three-way speaker, with horn-loaded tweeter and midrange that goes down to nearly 100Hz. The woofers are only used up to ~200Hz, and are acoustically close to the midhorns. Ext...

Re: stereo subs vs all around the room subs
Bass is omnidirectional unless the sound source is very large. The deal with room modes is interference between a reflected wave and the source, or between two reflected waves. It makes pockets of high and low energy throughout the room at frequencies b...

Re: Smoothing in Frequency response graphs
I have more experience with point sources, but I have measured arrays too. One thing I noticed right away is the absence of the floor bounce notch. Any time I measure a tower speaker or a monitor on a stand, I see a notch from floor bounce. Arrays don'...

Re: Horns vs Arrays
Other than high sensitivity, a three way horn system is pretty much the same as a point source with cones. The problem is that high quality sound with horns is very difficult to design properly, and often results in a horn sound which is great if you onl...

Re: Any opinions on AcouPower subwoofers?
Both the GR Research and the Bully subs were in my systems at different times each for month or two. I made them as gifts for my two sons. I liked both of them better for music than the sealed Tumult sub that I have. I never sat down to compare in detail ...

Line Array versus Point Source Kits
Manualblock asked me this question on another forum, but I decided to answer it here because the topic is line arrays:Q. In simple terms the Selah that you like and use as your reference are 4K$ in kit form. To a guy looking to spend 4K$; there are vast p...

Re: Xover question
HI Shane,Well, one can look at natural rolloffs of driver-box configurations & design crossovers with slopes that augment certain criteria (like flat response, unifrom sound energy, etc). In my experience the more nuanced your analysis, the less the retur...

Re: GPAF 2006
Bill, I'm glad that you enjoyed the line arrays. Regarding their output levels and such: I think that a lot of your comments likely was due to program material. I don't recall that we played much material all weekend that was heavy into the bass area. ...

Re: Speaker placement
The whole philosophy of multi-subs is to introduce dense interference. My point is whether or not the deep bass range should be covered by randomly placed subs or symmetrically placed subs, I think the midbass sound sources probably should be symmetrical...
