"LEVEL setting" does not equal "OUTPUT CAPABILITY". LEVEL setting is to match sub with your front speakers. It has nothing to do with the max output. I know it is too easy to make that connection. Even some of my best customers would say, "the sub is so powerful that I don't even have to set the level at more than 9 o'clock position". If I want to take advantage of that psychology, I would have increased the gain of subwoofer amp by 10x. However, that gain will introduce a new source of distortion. So I really want to use gain wisely.
The level position of 2-3 o'clock is about right if you have a highly efficient ported speakers. Sealed front speakers are normally less efficient. Also my Denon receiver has a standard gain of 20x power amplifiers. If you power amplifiers have higher gain than that, that will be another reason for you to set the level on the plate amp higher. If you have two units, then either unit's gain needs to set lower to get the same output.
Thanks Curtis! But I did decide to go with dual f12s. However, my receiver has only one output so I will need to get a splitter. Is this the one?
Can the sub signal be split and then split again to have a L and R connection on each sub? Or is it unnecessary?
I ask this because I have read that by having a dual connection to the sub, one can increase output over just a single connection.
Thanks.
Trojans under fire again.
You only need to split it once, and that piece will do the job.
Looks like Trojan Men's basketball is in trouble.

Nope...it doesn't matter.

Happy New Year!
It's been awhile since I've posted here. I guess I've been too busy enjoying my HT. I do have some questions for the HT gurus. I don't know what it is but I just noticed that the output of my two f12s seems to have decreased in proportion to my other speakers. In some scenes I can barely hear the bass like I did before. I tried Audyssey, but it didn't do the trick. I even tried to turn the freq knob all the way up. Therefore, I want to manually increase the sub level in proportion to my other speakers using the receiver or a setting on the f12s. What are some ways to do this? I am seated 14 ft away from my HT. I have all speakers set to small and I have put the distance setting of the front speakers to 10ft and the sub to 30. I have also increased the sub output on the receiver to LFE and +15db. They sound louder, but not quite like I want it. Am I asking too much from them?
My system still consists of Definitive 5.0 + two f12s driven by a Denon 2809. I am using a splitter to the two f12s. I have the freq settings at 14/high damping and the gain is usually @ 2-3 o'clock. I also added a ground loop isolator to my cable line if that matters.
