Ron: I appreciate your responses. While we could continue down this path for quite some time, i'm glad that you've at least taken the time to share what you did with us. It is enlightening to know that there are still manufacturers around that don't have much to hide and are willing to discuss the design decisions and technology that went into their products. It is obvious that the 1201 is built VERY sturdily and can pass a lot of current. I do have further questions that i'd like to ask you about this and other Mac designs, but i think that you've been quite gracious with what you have provided so far.
With that in mind, i'd like to pass on some further observations that are slightly off the subject, but i think need attention brought to them. Given our "basic agreement" on most points after clarification, i don't think that you'll disagree with the points that i'm going to make. I could be wrong though : )
"Yes the actual power of an amp is the main factor in controlling bass. 10 feet of speaker wire will usually swamp most dampening factor specs."
I agree with this statement and have stated so in previous amplifier / speaker cable / speaker related threads. This has to do with the fact that most speaker cables are very poorly designed and present such a high nominal impedance to the amp. Length of speaker cables isn't nearly as critical or detrimental to the amplifier / speaker interface IF the speaker cables themselves are of a very low nominal impedance. In this regards, and i know that he's speaking on his own and not for Mac, i disagree with the comments that Roger Russell has posted on his website to a very great extent.
"If an amp starts to pick up very high frequencies say from induction on the speaker wires this will get into the feedback network and may cause ultrasonic activity."
This further proves the points that i've tried to make in this specific post and other threads. Just one more reason to avoid speaker cables that are inductive in nature. That inductance is also what is responsible for the higher than desired nominal impedance of the speaker cable. Chalk another one up for low inductance, low impedance speaker cables. That is, so long as they are properly terminated with an impedance compensation network : ) Sean
