Excellent post(s) Josh! I had to ponder the statement that tube amps have more power reserve than SS amps. At first, I questioned it, but I think I understand your point now. Certainly tube amps do not clip the same way and measuring their max power, i.e. clip point typically has to be done at some objective level, when in fact they don't really objectively have a level in which they "clip". So yeah, they have more power on reserve, just at a raised THD level. A sort of compression like effect.
You remember Bob Carver's launch of Sunfire with the subwoofer - world's most powerful subwoofer or something like that out of a small enclosure. It created headlines and launched a successful company.Before that, when he was invited to leave Phase Linear he launched the Carver Corp. by making a 100 WPC amp in a Folger's coffee can. Big numbers in small packages are very impressive and garner the headlines and the investment capital.A lot of it seems kind of silly but that's what sells.
Emsquare(d)? Ow... Josh, buddy. I vaguely regret using that moniker. I had to call myself something though. That's OK. Still enjoy reading your thoughts as I pick out some nuggets of knowledge when I recognize them. Hope your holidays were particularly good to you.Signing off now. I have a date with the new Regina Spektor stuff I recently acquired. And a bottle of Bushmills single malt, 10 year. Wheee ..."On the radio, uh oh"
Ouch! Haven't gotten a name so wrong since Hemholtz, but that at least was understandable (and I'm not the only one to think he was "Helmholtz" either).
Funny you should mention the fancy panels. Earlier today I was flipping through some recent issues of TAS and one Jeff Rowland device caught my eye. I wondered just how much time and money went into manufacturing small lots of those sculpted faceplates? A lot, I would think.Frank Van Alstine finally started getting some real favorable press when he spruced up his faceplates a bit. Good for him and it shows how much our perception of value or worth is based on cosmetics. Many years ago I owned a powder coating shop and Rogue Audio was just a few miles away. They were launching a new line and were going to introduce it at some show.They had me do the powder coating and needed something really distinctive to draw attention to their product. Anyone who owns a mid 90s Rogue Audio component, I chose Morton Tuxedo Black powder. The trade show pieces were very handsome; I was too expensive for them to use for the production pieces but I'm sure that they were fine.Enough of Memory Lane.
I, too, would like to see Dave's comparative response measurements. The fact that the speakers were only quasi-gunned is insignificant to that metric. Of immeasurably greater importance is the proper context of the measurement procedure. To my knowledge, the results were never posted – all that I recall seeing on the PA is the modeled electrical response.On the topic of power requirements, I agree with Josh – context is everything. In my current situation with my MMG/REL hybrids, a meager 100wpc (200 into 4 ohms) solid state, integrated amp is more than sufficient – enough to run me out of my chair if I crank it. I have no doubt that I could get away with less. I also must say that there's 'magic' in such close proximity to the subs – the room seems effectively out of the equation.Speaking of equations, Josh, I think that's how you added the 'd' to emsquare's moniker. You were thinking of a formula (well, it's somewhat close to e=mc^2), whereas the etymology of his chosen representation is a form of representation itself – the typeface (specifically one with which the 'e' and 'm' are square). I read Hemholtz as Helmholtz for at least a year – our brains apply rules to that which we perceive without our consent (and Helmholtz was so familiar that I saw an 'l' that wasn't there).I love the story of how Rick Wakeman acquired his first Moog. A wealthy actor thought his was defective because it only played one note at a time, so he let it go fairly cheap. Obviously, that's not the whole story (or even much of a synopsis), but I don't have Rick's talent for story telling (he's brilliant at it, BTW).
If all goes according to plan MGBert is going to swing by with his Magnestands so we'll be able to compare them to the regular old MMGs and the 1.7s. I've never heard the Magnestands and he's never heard the 1.7s so it should be fun. We'll write up a review of sorts. Look for it sometime in early 2013.
It's 'no thing'. I just thought it was kinda funny so I thought I would play into the joke. As is my custom. Happy New Year to you.
