Woofer tower? If single woofer, it means the position is far from floor. If multiple driver, it is in one enclosure so no better than separate subs where you can position each of them more flexibly to cancel some room modes.
Of course, yes. It can be selected for 600 Ohm output impedance or 50 Ohm impedance. The spectrum analyzer also have 50 ohms input impedance.
Edited: I am almost forget the spectrum analyzer have two input impedance, high impedance and 50 Ohm impedance.

It all starts when we pretend we are not going to die, the self deception spirals downward from there. The final step in self delusion is high end cables etc. Of course if you are "reality challenged" enough to believe in bybees et al, eternal life right here on earth is not an issue. (-:
ANYWAY a new theorem has been pointed out to me...
Some Audiophiles can determine how a DAC will sound by looking at the digital square waves fed in to the DAC, it seems the shape of the square wave has a direct correlation to the resulting analogue output and how it sounds!!!!!!!!!
What digital square waves?
Digital signal accuracy is a function of time not shape
I cant imagine that there are any holes in that theory, That is valid, not snake oil at all.ANYWAY a new theorem has been pointed out to me...

I can see depending on the how the DAC input is built, rise time could effect temperature. Overshoot, ringing and other such analog issues ( digital is a concept, not physical) could effect various stages within the dac. Power distribution for one that may get imprinted on the analog output. Now, is the claim snake oil just because there is viable physics behind it? You would have to convince me that the dac system was correctly executed first. Poor layout or addressing the power supply would likely make the situation far worse.
I can see it now, all the reviewers coming up with "objective" tests with which they will ascribe garbage to nirvana depending on who bought the back page add.

Er we are talking digital, we are talking about looking at the digital waveform on a scope and from that you can correlate what the sound is going to be like, how come in my little world none of this ever comes up regarding digital design and layout, Ok we don't do consumer audio layout, but do pro audio analogue/digital layout, aerospace analogue/digital, medical analogue/digital layout, military analogue/digital layout, but we do follow digital design rules and procedures such as those put forward by Howard Johnson and others.
Now if you do not follow the digital design guidelines and information put out by the chip manufacturers, Howard Johnson, Henry Ott, Eric Bogatin etc. etc. you are likely to end up with something that is incorrect and may not work, but following audiophile layout beliefs and the forever chanting "well digital is analogue" you are probably guaranteed a failure.
But looking at the square wave going into a DAC will not correlate to the sound that is output.
OK thanks. And here is my opinion:
1) digital square waves is used to decode the analog signal. Inaccuracy can happen if there is too much drift in transmission time domain. In other words, inaccuracy will happen when there is certain amount or minimum jitter.
2) is there relationship between the shape of the digital square wave with jitter? I guess so. Bad shape is a cause of system imperfection. The same imperfection can promote data drift due to weak control on rise and fall times.
3) is jitter audible? If too much, of course. If a little? Then we need to find out what is the minimum amount to be audible.
4) to find this minimum we need (a) good ears. One may be able to hear what bad ears can't (b) resolving sound system, especially speaker.
5) My experience with reclocking. Long time ago my system was not as good as today. AND I didn't know if minimum jitter can give negative impact to sound. What I knew was that reclocking will improve things (and I knew more about digital theory then than now). So when I heard the result after reclocking, I got the feeling that I like the sound better before reclocking, so I took the time to restore my system to original setup. Please note, I expected an improvement and I didn't know if degradation was possible. So read between the lines.
6) if you want to do a jitter blind test, IMO I'm a good listener. I have good ears, the best I know, and I have very resolving speaker. You can consult Mooly and PMA who i believe can create test files with this synthetic jittery.
The funniest thing I've read to date is people in the audio community have stopped using their ears and are buying their audio gear based on 3 measurements:
-frequency response
-harmonic distortion of a 1kHz sinewave
-noise floor
A few pages in, this poster is defensive that if the THD and noise are below .005%, then it all sounds the same. Objective vs subjective thoughts

Space heater plus it makes music too at a whopping 18 watts per channel @ $25,000 per pair (mono blocks) .
Pretty pricey for a light show/hand warmer
