Here is some info regarding the test/listening setup.
The subs were off of a PL9.0 one channel to drive subs.
The mains were off a Clair/Carver 2.0. A yorkville TX4 was used most of the time for the full range-it was biamped.
Measurement mic (M30) was on the ground around 1M away-no exact distance as there was no reference in output voltage, just close enough so that the room did not become to big of a factor (which it did have some influence which will be seen). Yes this is to close for "proper" measurement, and the physically larger cabinet will have an apparent advantage in level due to physical size and distance to the mic.
Jeff Knorr did the Smarrt measurements using Smaart 6, but is having an issue displaying the data, but it is saved and can be opened by others-except me-(got to figure that out) for know.
It was just a quick-let's put a decent voltage level without getting to obnoxious and do comparative measurements. No compensation was attempted for different impedances, just a constant input voltage.
The listening was done starting in a group of 4 using a wireless switcher (I do not know if the outputs were shorted or no-I will check when I get back to the shop) and various material was played. Then by group decision (of those close by) one sub was taken out and replaced by another. This went on throughout the day with different types of material being played at different times at different levels-kinda free form.
When all of the subs had been gone through, we started bringing back different subs to hear against other subs at will.
During measurement the subs (measured singly and pairs that were available) were by themselves and the others a good distance away (say 20 times the distance to the mic).
When listening- the unused subs were that same distance away.
It was very unscientific, but lots of fun to be able to hear some the subtle (and not so subtle) difference between these.
We did not get stupid loud and see what the subs sounded like when really pushed-which would reveal some interesting aspects, there was nobody really asking for that-but I know Evan would have like it
.
Except for the lack of restrooms (Hey the side of the building worked well for all of us-we ain't proud
), the facility and "catering"-complete with a subshootout cake with flaming sub and a "to scale" drawing of Evan was good.
I think the only thing that went on as scheduled was the day it was held
.
Thanks again for hosting this.
