[QUOTE="Ivan Beaver, post: 71951, member: 30"] Re: Reasonably Priced Large Format Line Arrays The TH812 is not switchable to a 2 ohm load. It is switchable to either a single 4 ohm or 2x 8 ohm loads. Either way the sensitivity would be the same as the same voltage is applied. But for reference it is in a single 4 ohm mode. In this case-all the measurements were done exactly the same. Mic stayed in the same place-same drive level etc. The different cabinets were just moved into the same place and the same cable plugged into each. As a general rule-you pay a 9dB/octave "price" for extension. In this case-the intention was no to go real low (not everybody needs sub 30Hz performance) , but to get really loud in the "meat and potatoes" range 40-100Hz. The cabinet could be made a little deeper and then house 8 12" drivers-and the max output would go up 6dB. [/QUOTE]
