| The Anatomy of the Acapella Violon - shocking find Thanks Rodman and Ralph. Rodman, I do not think that equalization would help because (1) the rolloff at 60Hz can not be fixed with equalization and (2) the problem is with system Q, which equalization can not fix. Ralph, I said that the interconne... | |
| The Anatomy of the Acapella Violon - shocking find Ralph, I do not normally use my 10m speaker cables! The 10m speaker cables are left over from when I used to run my rear speakers from the HT and are normally in storage. In normal use - preamp-power amp cable is 5m, and the power amps are right n... | |
| The Anatomy of the Acapella Violon - shocking find Thanks for your input Jacek. I have been listening to the CAD-200 for the past few hours. Result: it HAS removed most of the muddiness and the bass has better definition - but it still does not go very low, and the woofer is still noticably slower... | |
| The Anatomy of the Acapella Violon - shocking find Well i've got in my living room a Cary CAD-200 solid state amplifier which I just borrowed from the dealer. I will unpack it later and see how well it controls the wayward woofer. Rlawry, mine says "High Violon 2001 Suboktav". Weird - I would thin... | |
| The Anatomy of the Acapella Violon - shocking find Hi all, thanks for your suggestion of trying to bi-amp with a SS amp at the bottom. If I am going to go active, I will need two more channels of amplification anyway so a beefy SS amp is on the cards. NOW ... given that I only need to run these fr... | |
| The Anatomy of the Acapella Violon - shocking find Sorry for not responding for a few days. I went and did some research on this type of woofer so that I can better understand the designers intentions. However, all my reading indicates that the inner woofer should be rolled off lower than the exte... | |
| The Anatomy of the Acapella Violon - shocking find Ralph - sounds like a great idea! I'll ask him what he thinks of it. Would the caps and inductors need to be changed as well, or only the resistors on the notch filter? Could be a good temporary solution. Duke, very interesting and helpful comment... | |
| The Anatomy of the Acapella Violon - shocking find And Shane ... I have not contacted the manufacturer. Not too sure if they speak English (they make this lautsprecher in Deutschland). I should also say: I realize that I have probably come across as being pretty negative about this speaker so far.... | |
| The Anatomy of the Acapella Violon - shocking find Duke, the woofers are NOT in isobaric configuration. Isobaric (as I understand it) means: two woofers, fed the same signal and wired in parallel, located very close together. At bass frequencies, the distance between the two woofers is much less t... | |
| The Anatomy of the Acapella Violon - shocking find Duke, my understanding of an isobaric woofer is that BOTH woofers receive the same signal. In this case, the outer woofer is receiving a signal from the crossover, and the inner woofer is receiving a full range signal from the amplifier. All cross... | |
| The Anatomy of the Acapella Violon - shocking find Duke, thanks for your response. Correct - the woofer that faces outside has the 450Hz crossover, and the internal one is full range. Yes, the woofers are identical. The woofer crossover has about a dozen parts. 3 inductors. Across each inductor is... | |
| iPod vs CD: WSJ CES Arbuckle, I think his name is "Rotarius" :) "Rotavirus" causes diarrhoea. But yes I do agree - a negative result doesn't mean much in science, especially when it is conducted by someone with an obvious axe to grind like this guy. Experiments can a... | |
| iPod vs CD: WSJ CES Thank you very much Yehuda. Very provocative read indeed! :) I enjoyed it. | |
| iPod vs CD: WSJ CES Sounds interesting - do you have a link to the article? | |
| passive vs. electronic passover There is no doubt that removing the passive crossover will improve control over your woofers. Nobody argues against this. It is theoretically better. It is measurably better. And it is certainly audibly better. In my own car audio setup, convertin... |
