| 4 ohm vs 8 ohm taps inpepinnovations@aol.com...How can you say that a zero ohm load is "seen" through transformer coupling, but yet loudspeaker loads are not?In another area, when you use a step up transformer for your moving coil phono pickup it can be connected to ... | |
| Ring radiator tweeters - the future? The so called "tweeter" of the Magneplanar QR series, like my MG1.6QR, is not a physically separate driver, like the ribbon used in the MG3.6. It is just a section of the diaphram that has lighter conductors and can vibrate at higher frequency. In... | |
| Two Questions... Oh boy! You asked for it.Bose says that this system "Effortlessly blends with your décor". This is quite accurate, and if this is very important to you then you will be happy with the Bose system. | |
| THE LATEST---Gold plated fuses? Actually, gold plating on electrical contacts is a pretty routine way to avoid resistance due to corrosion. It ought to add not more than a few pennies to the price of the fuse. | |
| Ring radiator tweeters - the future? Gmood1...The Fostex FF225 appears to be much flatter out to about 12KHz, where it drops off completely. At the low end there is a rolloff starting around 200 Hz, but it is smooth and gradual and easily handled by equalization down to where a SW wo... | |
| Ring radiator tweeters - the future? .Gmood1...I assume the the Fostex F200 is what you use. Good choice. No whizzer. But look at the almost 10dB hump between 4 and 5 KHz. And how about off axis? And you can't really tell about the HF (15 to 20KHz) from a SPL measurement. Sure it put... | |
| Ring radiator tweeters - the future? Gmood1...Why do tweeters exist? Because drivers with large cones, necessary for LF reproduction, are lousy for HF. "Lousy" means irregular frequency response within the pass band (peaks and dips) and premature roll off, sometimes covered up by a k... | |
| 4 ohm vs 8 ohm taps inpepinnovations@aol.com...You have it backwards. The different taps of the transformer secondary make it possible for the tubes to see the same (high) impedance with different loads. Here is a way for you to test your theory. Short out the speake... | |
| Hearing loss and center image In the good old days preamps had a balance control...but I really don't think that making one speaker play louder than the other will help. Both ears hear both speakers (or are supposed to). I would suggest correcting the problem where it lies, in... | |
| 4 ohm vs 8 ohm taps inpepinnovations@aol.com...The primary impedance depends greatly on the secondary loading. If it didn't why would transformers have multiple taps? | |
| MC transformers - what do they sound like? Raul's system should be called "Shiva". All those arms! | |
| Too good to be true? .OK I found the book.The Professional Fenceby Carl B KlockarsPublished by New York Free Press (1974)Originally presented as the author's thesis, University of Pennsylvania.A very interesting read, even if you can't stomach the conclusions.. | |
| UcD vs TriPath Digital amps. I continue to enjoy my three CIA D200 amps, and have ordered two more for the surround channels. Nevertheless, it is hard to describe exactly what is so good about them. I am not a professional high end reviewer with fancy subjective words like "t... | |
| Bargain interconnects to tame treble & boost bass? Trelja...As I have commented before, I bought the thing just for the spectrum analyser, and I have analog parametric equalizers which I fully intended to use, based on the spectrum analyser data. But once I heard the DEQ2496 eq results I was hooke... | |
| Ring radiator tweeters - the future? Gmood1...The frequency range chart that you cite is for the fundamental tones. Harmonics do go to 20KHz and even higher. But I do agree with you that the low and mid range is most important, and a bad tweeter is worse than none at all. |
