| How does excessive sibilance measure? Read somewhere that sibilance is in the 5 to 7 kHz region. That's the same area where metal midrange/midwoofer breakup occurs. Easily compensated with a (LRC) parallel notch filter after the low pass. With the value of the inductor being low (.08 ... | |
| What is Imaging? Tricks, illusion and deception. Convincing and convenient perception. | |
| Crossover upgrade? Hard to get any detailed info on those. I do remember that B&W likes high crossovers around 4K. You really need a goal to know which way to go.If your crossover looks anything like this...http://www.ebay.co.uk/itm/B-W-MATRIX-1-SPEAKERS-GOOD-WI... | |
| Wireless Speakers? If it's bluetooth, don't. Any interference sounds a lot like the speaker is blown.Tried something like this using for the computer using a Logitech bluetooth receiver, a Lepai 2020 ($25) and JBL Loft30's. Ended up plugging into the headphone jack ... | |
| It was 20 years ago today. . What was your system? Sonic Frontiers SFT-1Monarchy DACMission 776/777Infinity Kappa8'sThat combo lasted for years with some biamping. | |
| How to meaningfully audition speakers?? Never judge a book by it's cover. If, for example, you've had bad experiences with planars or metal tweeters, or whatever, I'll guarantee that there's something out there that's going to surprise you.Consider your room, placement of speakers and t... | |
| Question of the day for speaker guru's. Parallel o Since inductor and capacitor values are larger for higher impedance, two 8 ohm speakers wired in parallel for 4 ohms would use extra, bigger and more expensive crossover components than a single 4 ohm speaker like the Ulysses. "Conjoined twin spea... | |
| Stepdown transformer 240v - 220v "What is the difference...?"Between the Tortech and the Signal SU/DU at 2000 watts, about 20 kg and several hundred dollars.An autotransformer only has one winding and offers no isolation and no filtration. They are more efficient per weight and c... | |
| Stepdown transformer 240v - 220v Or http://www.stepdowntransformer.com.au/product/ae2k/These have got to be autoformers/converters. Real transformers with primary and secondary windings would be a lot heavier.The following are transformers but don't have an enclosure and require ... | |
| Stepdown transformer 240v - 220v Minimum I would recommend for ANY amp is 2KVA. Maybe 1.5 KVA for an autoformer but I would rather have the isolation of secondaries.2000W / 240V = 8.33A http://www.ebay.com/itm/Voltage-Step-Down-UP-Transformer-220V-240V-100V-2000W-Europe-China-etc... | |
| Shifting absolutes Bass bumps are typical for any speaker in any room, depending on the listening position. Hard to avoid. Maybe those bass bumps were better for his room/position.Wouldn't be surprized if anyone who thought his system was "neutral", or even "bright"... | |
| How quiet is your room? Not far from a highway, so 50's during the day and 40's at night. Depends on weighting. | |
| Sub-woofer fast enough for Horns? Technically subwoofers don't need to be fast as the frequencies they do are relatively slow. As far as the mass argument, it's more the ability to stop than go. Rythmik uses a servo system that allows the driver to be a bit lighter but, usually, h... | |
| What's with 4 ohm speakers? Finally got around to that test I mentioned earlier.So I built a single test speaker with 5 individually sealed Dayton DS135-8's (5"). Not normally a choice for a sealed enclosure but fairly conventional except for a high Qms,low volume requiremen... | |
| Peak listening levels- Over 100. Concert levels. Sometimes louder, depending on the seat. |
