A full range speaker?
Doing the math.Sound travels about 1100 feet/second at sea level, and for you nitpickers, at 50% humidity and 72 degrees. A cycle of 25hz happens, surprise, 25 times a second.Divide 1,100 by 25 = 40 ft. A 25hz tone is 40’ long, but it happens 25 t...

@millercarbonUsing an online tone generator I can hear and feel sound down to under 20hz in my listening area, how coherent that is is another matter. But looking at sound generation, no driver moves anywhere near the distances you describe in gen... 
Best Preamp and Amp combination, interesting finding!!!
Preamp is the resolution/depth/sound stage/dynamic range tool, amp adds the SPL. So, like computers, GIGO. Garbage in, Garbage out. 
Old Amps that can still Kick Butt
Love questions like this, great question, interesting answers. Lots of good info.I have an Adcom 555II that I am trying to decide whether to rebuild from the resistors up, not just the caps. Nelson Pass design, how bad could it be with a soft star...

@atmasphere Thank you for the information. There are so many tube amps I have never heard of. Fortunately many posters here have been providing new ones for exploration. It seems the only way to start to be informed is to attend the major audio sh...

@Decathlon1991Please don’t make me talk to Wendell. 😉

@kellypYes, Magnepan’s are another compromise in the speaker world. Good enough? What is "good enough"?

@drbarney1 Thank you for the info and offer. Not going to be building any new amps for the foreseeable future as I have some rebuilds in the works and am also building some Fostex folded horns this year. But I will put the link and your note in my...

The one thing that is already done is changing the speakers over to bi-amp connections, so I can indeed drive the woofers with a ss amp and the mid-hi's with a tube amp. Experimenting with adding depth to the baffles today to improve bass. I think...

The first time I heard Maggie’s they were hooked up to Audio Research equipment, 1978. That's when I first fell in love with them.

@pkatsuleasThank you. A wealth of information pertinent to the topic.

Sorry, school isn’t in session. I’m discussing tube amps and Magnepan’s here. Sometimes I get too close to sharing things that should not be.Knowledge isn’t necessarily power, but knowledge and money can be.

Or they could use less pure foil tape... Length x diameter x resistance is total resistance. You don’t have to use a resistor to increase resistance.
