| How Do I Build a Faraday Cage? That's great news Spencer and i'm quite certain that this approach was FAR easier to impliment. Most everything that you've mentioned are known cures to known problems, so it's good to see that some of the old stand-by approaches still work as exp... | |
| Please explain amplifier output impedance Tvad: Unfortunately, there is no "Big Dummy's Guide To Assembling A High Fidelity Music Reproduction System". It's NOT that easy. But then again, if it were that easy, you would have to find some other frustrating and equally expensive hobby to sp... | |
| Please explain amplifier output impedance Duke: I don't need to tell you or anyone else that has truly dug deeply into designing / building a great speaker that the amount of work / R & D ( research & development ) that one can put into such a project can be mind-boggling. The thi... | |
| A great article on Class D/switching amps I dropped my subscription to TAS a while back. Can anyone offer what specific issue this article is in? Sean> | |
| How Do I Build a Faraday Cage? If you want it to work OPTIMALLY, you need to use thicker materials that are solid. The cage would also be attached to a low resistance Earth ground. Aluminum is FAR less desirable than steel and to a lesser extent, copper. Using thinner materials... | |
| Please explain amplifier output impedance Tvad: The speakers that came to mind right away were the Coincident's that you mentioned. I don't know of others that i can rattle off though, as i really don't pay attention to / go out of my way looking for such designs. Most all of my gear / in... | |
| Please explain amplifier output impedance Tvad: There isn't a specific point where an amp is either considered to be high or low output impedance as it is a relative thing. Having said that, a lower output impedance is typicall considered to be a more desirable trait in most cases. As pre... | |
| Please explain amplifier output impedance This is one of the reasons why i strive to build GOBS of dynamic headroom into my systems and believe in multiple amplifiers that are actively limited to covering only a small portion of the audible range. By reducing the stress on any given part ... | |
| Please explain amplifier output impedance I've specifically mentioned the Td ( Time delay ) of a circuit that Ralph makes mention of several times in the past. Shorter signal paths with a consistent impedance will have a lower Td, which is a good thing. I only know of one manufacturer tha... | |
| Please explain amplifier output impedance Arthur: Those are very good points and well worth clarifying. Thanks for taking the time to point them out AND explain them. I have often said that it is the sum of manufacturer spec's that count more than any individual spec by itself. Even then,... | |
| Xover parts quality,/sound difference? Dbld: Most commercial designs are SOOOO far from being electrically optimized that just covering the basics i.e. better connections, better conductors, shorter signal path, etc... will almost always introduce better sonics. Parts tolerances and me... | |
| Can someone guide me as to what Single driver ?? Elvis: I've just been watching the audio detectives and learning from them, their discoveries and their mistakes. Most everything that i've ever learned and / or shared here ( or in other audio forums ) is an accumulation of information that i lea... | |
| Please explain amplifier output impedance Negative feedback in high levels is quite audible and it doesn't sound good. Most of it can be avoided to a great extent IF the circuit is properly designed and parts are very carefully matched. Most parts aren't matched all that precise and the a... | |
| Can someone guide me as to what Single driver ?? Duke, for an inexpensive driver, the Eminence Beta 12LTA offers pretty wide bandwidth and high sensitivity. Eminence has recently revamped their measuring techniques, so some of the spec's may be different than what is posted on PE's website. Lot ... | |
| cable dielectric cause of artificial sound Dazzdax: I would not doubt that Audioquest's "DBS" system is based on something similar to what i'm experiencing. Without talking to Bill Low, i'm strictly guessing at that though...Tplavas: I was working with standard "foam" dielectric as found i... |
