| If Audiophiles care about sound, then why so few threads on acoustics What did you do with the other geoffkait? | |
| What Do You Think . . . and How Does It Work? At the same thickness PVC is similar in strength to MDF. With the "bend" forces exerted on a speaker enclosure, a tube is a significant advantage over a box making the comparative thickness higher but that would be compared to an unbraced box. | |
| Directionality Explained I assume at 50-63V. You won't get 105C/10K hours in those values unless you build it from a bunch of smaller ones. You may find one, but very expensive. There are 8,000 hours at 105C and that is likely close enough. Nichicon, UCC (United Chemicon... | |
| Directionality Explained I have forgotten the details of what I learned, but not that the knowledge exists, and where/how it is used, and many of the other things I learned and forgot the details on provided the framework for understanding other pieces of knowledge. When ... | |
| If Audiophiles care about sound, then why so few threads on acoustics The way to deal with the "spouse" factor is to take them to a fabric store and let them pick the fabric (avoiding ones with "shiny" coverings). Rectangles are used because they are easy, but other shapes work too. We built some octagons because 45... | |
| If Audiophiles care about sound, then why so few threads on acoustics This happens when people apply too much absorption.While I agree that it’s very important, I some times wonder that without specific measurements, that hap-hazard room treatments can sometimes do more harm than good? | |

| In the middle of a pandemic, Stereophile reviews ~ $30K equipment If you believe this, then you are miss-allocating your funds. $20K is not bare-bones, unless you are wasting a ton of money of audio jewellery and not things that will really make a difference, like speakers, room acoustics, a tolerable source and... | |
| Directionality Explained Since we are talking engineering, my experience is, the ultimately better engineers, at least if you are trying to accomplish difficult work, are the ones whose marks were 80-90%, definitely not the ones near the bottom of the class. If they achie... | |
| If Audiophiles care about sound, then why so few threads on acoustics I would also apply the GK factor, where the ultimately usefulness of a thread = 1/GK, where GK = the likelihood that geoffkait will post in a thread. This greatly skews the post count and ultimate usefulness of a thread, but anecdotally it is rare... | |
| Directionality Explained What value of capacitor and how are you using it? 10,000 hour, 105C capacitors are quite common up to a certain size and reasonably priced with lots of different vendors. | |
| If Audiophiles care about sound, then why so few threads on acoustics Except 50% of those GIK posts are yours Erik :-)Seriously though, I just looked at the last several hundred active discussions. 1 was definitely about discussions, 1 sort of, and I know they are mentioned any time subwoofers are brought up. In tha... | |
| Distortion on the Power Line Believe it or not, power companies may be interested if you get the right person. High THD is not to their benefit or liking. | |
| If Audiophiles care about sound, then why so few threads on acoustics Maybe that is it ... the average audiophile just does not know what they are missing and don't understand that if you have not acoustically treated your room, what you are missing is likely substantial. | |
| Directionality Explained Well said Schubert. The teacher had little impact on how I did, but I watched struggling students fail with bad teachers, and excel with good ones. |
