| soft dome versus hard dome tweeters @asctim There is a design called "woofer-assisted wide-band" or WAWB for short. It's exactly what you describe. A wide band, such as a 4" driver that has credible output in the top octave along with a woofer that crosses in well below 500 Hz. Ch... | |
| Hegel hum? Is the hum mechanical? If so it can be related to DC in your AC. Try turning off every other breaker in the home to try to locate it. | |
| Nuisance tripping of AFCI circuit breaker by inrush of current when turning on amplifiers If it really is an AFCI tripping, consider swapping out power cords as well as changing the order of amplifier starts. I do repeat though, first generation AFCI breakers (1999 ish) were more jittery than the second generation CAFCI breakers. | |
| Nuisance tripping of AFCI circuit breaker by inrush of current when turning on amplifiers I almost firgot. Afci, cafci and gfci breakers include diagnostic LEDs. If they arent on you have a plain old overcurrent trip. | |
| How can they not effect the sound Depends where. For a dome tweeter a dent can do a lot of bad things. The use of a vacuum is a great fix. Also, with some tweeters the dome is removable and you can fix them by pressing from behind. This is the preferred solution with tweeters, as... | |
| Krell FPB 700CX @invalid It may have to do with the protection circuitry. If you don't have a blocking capacitor it's a good idea to have some sort of amp and speaker protection circuitry. Either detect DC and disconnect the inputs and outputs or adjust the b... | |
| SPEAKERS THAT SOUND ALIVE & DYNAMIC AT LOW LISTENING LEVELS The benefit of ESLs and other planars comes from dispersion. There's less reflected energy horizontally and vertically hence the proportion of direct sound to reflected is higher. I hadn't really thought of this as a good low volume listening tr... | |
| Nuisance tripping of AFCI circuit breaker by inrush of current when turning on amplifiers Ps, the online forums complaining about first gen. AFCI tripping have settled down quite a bit with the second generation CAFCI versions. Last, really, ive seen power conditioners with very large toroids trip breakers, had nothing to do with AFCI | |
| Nuisance tripping of AFCI circuit breaker by inrush of current when turning on amplifiers Also, check with the manufacturer. With AFCI breakers now required in all residential circuits this should be something they are aware of. | |
| Nuisance tripping of AFCI circuit breaker by inrush of current when turning on amplifiers I would definitely start with a second generation Siemens CAFCI breaker. Im not sure about your situation butI have 20 Siemens CAFCI breakers, all upgrades fron non AFCI and never had a nuisance trip. | |
| Impedance - The most ignored and useful measurement tool Call me petty but I am still upset. 🤣🤣🤣 | |
| My Sonus Faber Amatis have weak bass even though I'm running ML 536s--800 w/ch into 4 ohms BTW, if your room is reasonably rectangular, I suggest examining the results from the AM Acoustic room mode simulator here. | |
| My Sonus Faber Amatis have weak bass even though I'm running ML 536s--800 w/ch into 4 ohms I don't know about packing, but assuming your speakers have rear wall reinforcement and you haven't put them in a bad modal location your next option is some room treatment. In a very reflective room the speakers will sound excessively bright, al... | |
| Overly sensitive tweeter/midrange You know, switch seating positions with your wife. :D Seriously though, I’ve had untreated rooms create a kind of distortion effect above a certain listening level. If you two are sitting in the exact same place while evaluating it may be an acou... | |
| soft dome versus hard dome tweeters I want to repeat myself a little though. Tweeters don’t matter. They are the sprinkles on top of the doughnut. Midranges matter. I’m saying this a little funny, tongue in cheek, but honestly we pay far too much attention to a device that may not... |
