| What does more power do for Magnepans? El,Thanks. More coherent than I could of posted to Dan's question.Dan... I went to active biamping for a couple of reasons. The 1.6's are reputed to benefit greatly from better crossover parts. My little Arcam Alpha 10's are 100w/8ohms 170w/4ohms ... | |
| What does more power do for Magnepans? El,No, it is a digital multi-meter. Just slow to react. Less than $10 at RS.To do total amp output I would have to undo the active biamp setup and reinstall the passive crossovers in the 1.6's. And get better measuring equipment! Your early result... | |
| What does more power do for Magnepans? Bob,I set the volume pot at a level that I occasionally listen to and left it there. I was more interested in measuring at a known volume level to see how much juice the speakers were pulling. They are both "modern" recordings (CD) and fairly clos... | |
| What does more power do for Magnepans? El,I did make some measurements at lower SPL's and although I didn't make note the specifics, you are correct. Voltages go proportionately lower, by a bunch.Also understand your point about rms vs. peak, and yes, that was a misstatement on my part... | |
| What does more power do for Magnepans? Just to follow up. I got to sit down with a RS multi-meter, SPL meter, and check voltages at the speakers for different levels and kinds of music. Because the 1.6's are setup "active" (acoustic crossover is around 700 hz) I was able to easily meas... | |
| What does more power do for Magnepans? Thanks Eldartford. Jim S. | |
| What does more power do for Magnepans? Eldartford,Thanks and I do remember your thread now that you brought it up. I've read so many maggie threads it becomes a blurr. I am slowly learning how to figure this stuff out myself. (Mostly by putting my foot in my mouth).Quick question if yo... | |
| What does more power do for Magnepans? I think I have corrected a couple of mistakes. Still ignores room loading, absorption, and full spectrum of frequencies.86db/1m/2.83V = 86bd/1m/2w. Not 83db/1m/2w.If you listen at a level that produces 96db peaks it would go something like thisÂ…2w... | |
| What does more power do for Magnepans? Thanks Bob,A fundemental misunderstanding on my part. Does change the result, doesn't it! Jim S. | |
| Arcam phono board - problems DD,Nice to see you post the follow up. Sorry to see the hum is still there. Does sound like the Rotel has some power line filtering that squashes the the hum that the Arcam doesn't have.And yes, sometimes you do get what you pay for. The boards we... | |
| What does more power do for Magnepans? I tried to go back and study some of the math about maggies and power. These were pointed out by others; I am just trying to pass on their work and analysis correctly. First thing I ran across was the way Magnepan spec's the efficiency. 86db/1m/2.... | |
| Are attenuators linear or logarithmic? Gs,Thanks. I was just trying to estimate how much power the amps were pushing (or maybe better yet, the speakers were pulling) at certain levels of attenuation. I recently went active with the speakers and was trying to guess at the change in spea... | |
| What does more power do for Magnepans? Mr. T,Wasn't picking on you, just wondered. About where I sit from my 1.6's.I know you like solo and small ensemble acoustic music and evidently the smaller tube amps work well for you. It is just so opposite from my (I will admit, limited) experi... | |
| What does more power do for Magnepans? Mr. T,Just how close do you sit to your 1.6's to get 72 - 82db with 4 watts?Jim S. | |
| Arcam phono board - problems DD,Good hunting, and I hope it is just a pin or grounding problem.Jim S. |
