Uhhh.. Tyler, in no way did I say that the all other speakers were set to small. The front left and right are set to large and the rears are set to small. The small setting PREVENTS low frequencies from getting to them. Also, their natural low frequency cut-off due to design is about 320Hz so there is a roll-off of 12dB/octave anyways. I can set them to large but not having to try and reproduce bass also cleans up the sound.

And, yes, the middle channel and rears are indeed tiny POS's that were intended for a Pro-Logic system. However, it works extremely well for the price (which happens to be next to nothing). Everyone who listens to the set-up is quite amazed and they do the job extremely well. I understand the concept of being surrounded by full-range speakers, but, human hearing is greatly diminished in listening to sound from the rear. Both in pin pointing the location of the sound as well as frequency response. You can pick up any book on audio engineering and they will go into great length of this and may even provide a graph of the human range of hearing in relation to sound coming from behind and from the front.

I am in the process of building 6 new speakers. Which is quite a tedious task. They will be able to accomodate anything.

The left and right front to have a response down to 70Hz or so, however, setting the crossover at 100Hz instead of the standard 80Hz improves the sound. They each have a single 6 inch driver which does not have enough surface area to create low frequencies in the way we would like. They can do it but not effectively. Therefore no point.

And, I have two 15 inch sub woofers that WILL CREATE WIND ON DEMAND if need be. You want a pressure drop in the room? No problemo. Besdies, I prefer to not let any speaker try and reproduce low bass frequencies. Best to leave that to the sub. It is very hard and very expensive to find drivers that can reproduce low frequency without becoming exponentially inefficient. They do exist, however, they are very expensive. 20Hz is simply a number and not necessarily a measure of quality.

BTW: there is no standard for frequency response in relation speakers and I have seen very few manufacturers provide the dB at the lowest frequency as well as the highest. Amongst other things.
