is there a consensus on too short speaker cables?

"An old friend, who is an MIT insider, once told me that Bruce Brissen says speaker cables needs to be at least 8 ft to propigate a solid bass wave.
"

Couldn`t be more wrong, but that doesn`t co me as a surprise. Most cable-designers have no clue of what they`re doing, they`re just making money.

Speakercabes must be seen as a part of the amps powercicuit and should be as short as possible. For transistor-amps they also need to be thicker than most "experts" claims, positive and negastive signal-halfs should be kept apart (to avoid interference) and conductors should be thick & massive, not stranded or flat.

What is your technical discipline and/or expertise to make such a misguided statement?

It's a fact that many cable manufacturers have electrical engineering, physics, and other scientific degrees so let's not jump to conclusions when speaking about other people who are far more knowledgable than thee.

If you haven`t realised this before I`m afraid I can`t help you mister, too bad.
One of the rasons why I know is because I`m bright enough to understand what really counts in this picture. The clue is: keep it clean, heavy and simple

Thanks for that wondeful insight Mr P. I just got back from AutoZone where I purchased two pair of jumper cables. Based on your empirical data and profound wisdom: They should really perform great, and add a macho touch to the system as well. Now- How to get these clamps onto those 5 way........

Well, if you intend to terminate two five-way speakers only by using a pair of jumpers you might think of redoing your math:P
The dynamic loss in passive speaker-cables/filter are dramatically underrated. About 98.37% off the loss could be avoided simply by redesigning filters and generally uppgrading the area of all parts involved in the circuit.
How many sets of cables do You need to set up the five-ways? 3-4 sets? A waist of money if you ask me, but you`re local salesman my disagree. Save up for another amp and put the amps right up to the speakers, then mybe you can use the jumpers too;)
