Dampning factor. I did read a topic on that and saw that the wire resistance is also included, amazed at how everything worked out to a very low value.
As a weekend warrior i run small venues, 25 feet is a big spread for my subs so I run very short lengths.
Slew rate. I'll have to look that up and do some research.
I'm very big into snowmobiling and modded out engines. Ben on a dyno many a time. There are certain things that individual companies can post hp. and torque numbers that seem great on paper, but actually not good in the field. Numbers sell, thats why I tune on a independent dyno that gives real world numbers.
I'm beginning to see the same in the amp specs. Specs don't always mean everything. My vs 1500's sound great, but are very heavy, My ca9's sound great, but are very heavy.
I put the 8200's on the bottom end and was very pleased, even with some specs that are not close to that of a vs or ca.
I have tried many amps, never any of the crown macros, or itechs. I have yet to hear a better amp then a crest. They just seem uncolored, like its not there, very natural.
I have 2 more 8200's coming, as I will be building 2 more double 18 box's. I still want a 9200 for the jbl 4733's. I'll keep the 2 ca9's I have for monitors, and loose the vs 1500's.
A friend of mine who also was a crest fan wanted something lighter, he bought crown xti amps, specs looked good, they may be the worst amps we, I ever heard on the bottom end.
