[QUOTE="Canaan, post: 7670034, member: 566706"] I have done 163's w/ a single 8" on 400wrms in a USACi portwars setup. Maybe he had a BS shop install the setup and meter it at the port??? Sadly, I have seen some local shops pull that trick to help 'sell' people on a setup. For instance, a local guy w/ 2 Crossfire 15's was "metered" 151ish by another local shop on their Audio Control meter. He later came to me and I metered him on my TL...he hit ~144dB. Those of you that have had experience w/ the AC-meter know exactly why 'that shop' was able to show his system hitting 151...lol...sensitivity knob. For those of you that don't know about the AC-meter. On the main unit, there is a sensitivity knob. If the meter is calibrated properly, then you can easily get close to a REAL # for SPL...but all it takes is a little turn of the knob to fake a score. Even during a competition w/ the AC meter...one can just turn the knob and 'show' afar higher score than what is really happening. That is what makes the TL great, during a show the meter sensitivity is LOCKED based on the K-value of the sensor within the computer program. That way, everyone is on the same playing field. But w/ the AC, all is takes is a little turn of the knob on the main unit to falsify a score. Hell, years ago I used have have friends stand guard behind the judges booth for Whitley SPL shows to make sure people didn't get robbed by the judges changing the mic sensitivity. [/QUOTE]
