Ait, I'm not sure why exactly, but I have to admit I'm impressed. Were those amps custom made, special order, or available off the shelf? |

Atmasphere, am I to understand that you're suggesting that as long as an amp avoids actual clipping that it will sound more powerful the more it distorts? |

Dopogue, an apple (pinklady) to apple (golden delicious) comparison? |
With typical speakers, though the impedance might change, the sensitivity also changes accordingly. A typical quality ss amp will more likely maintain flat frequency response with varying power output to the fluctuating impedance of typical speakers. A typical quality tube amp will more likely deviate from flat frequency response with steady power output to the fluctuating impedance of typical speakers.

^ I would agree that the softer clipping of tubes might make the sound of tube amps seem louder than comparably powerful ss amps, but as tube Watts often cost more than ss Watts, one might be able to buy extra ss Watts for the same money to compensate for the clipping issue, and perhaps more readily dismiss it altogether. Perhaps it might be wiser to compare amps on the basis of cost rather than Watts? Of course, that is not to say one shouldn't consider power output ability when purchasing appropriate amplification.
Is this "...excess of electrons near the plate." consistent and/or linear?
Sorry but, I'm not sure that "This is why guitar players tend to prefer tube guitar amps BTW." is necessarily true. Creating sounds is quite a bit different than replicating them. |
I answer to jmcgrogan2's question and to follow up on Drussheaxe's response:
Current US law dictates that:
mercantile products (cotton) are weighed in Avoirdupois ounces
physical bullion (gold) are weighed in Troy ounces.
Avoirdupois ounce = 28.349 grams
Troy ounce = 31.10 grams
Avoirdupois pound = 16 Avoirdupois ounces
Troy pound = 12 Troy ounces
Avoirdupois pound = 453.504 Avoirdupois grams
Troy pound = 373.2 grams
10 pounds of cotton = 4.53584 Kilograms
10 pounds of gold = 3.732 Kilograms

^Don't know enough about you to decide whether or not I like you, but I do like your sense of humor!
I don't typically care if I'm liked. Good thing, or otherwise I'd be terribly disappointed. |
Drusstheaxe, please accept my apology for previously misspelling your username. |
"...200wpc SET amp..."? What amp might that be? |
^Thank you, but I'm not deserving of it.
A true scholar would have noticed That "I..." should have been "In...", and there is no such thing as "...Avoirdupois grams...". |
Bop Reynolds, look at these pre coincidental driver Thiel impedance plots:

^The 3.5's were sealed boxes. Keep in mind the slightly elevated impedance peak on the 3.5's occurs just about where the supplied bass booster eq comes in. So just where the extra drain on the power amp required from the bass eq comes in, it's offset by a higher impedance with it's correspondingly higher sensitivity. Though perhaps not evident at first glance, the subtle deviation from flat impedance at just the right frequency actually makes for a more linear load on the amplifier.
Perhaps the coincidental drivers; though they might have other positive attributes, might compromise linear impedance? |
