To follow up, so you suggest that even when I get the larger speakers, the 51's, to still keep my speaker settings as small even though my receiver will read them as large?
Correct. This is for at least three reasons.
1. The left and right sound channels of movies include sounds which are below the lowest frequency that can be reproduced by any but the very largest, self-powered woofers -- ones which would be subwoofers in any other system. When you set speakers to Large, the receiver will send those low frequencies to the speakers and they'll be lost.
2. When the lowest frequencies are emitted simultaneously by two woofers facing the listener, they often will interact with one another, causing peaks and valleys in the sound levels heard near that position. Adjacent locations would experience significant differences in the volumes of the lowest sounds. You need to be able to move subwoofers to different locations in the room to get the best audio response, especially when you're using more than one sub.
3. It's good to relieve the receiver from having to provide the power needed to generate the lowest frequencies.
Secondly, I noticed that my receiver does not have an LFE output as you mentioned. I simply have a R and L line in to confirm.
I'm somewhat confused by this description. A line-in on a receiver is for connecting to a player, not to a speaker. Do you mean a line-out?
I've downloaded the manual for your receiver. The VSX-52 a high-end model designed for use with as many as two subwoofers. It has two subwoofer RCA connections in the middle of its back panel. See page 11 of the manual for a picture, and page 12 for a description of how to use those connections. As it says, you should connect your subwoofer to the connection labelled "Subwoofer #1", which is immediately above the "center channel" RCA preamp output.
If your receiver doesn't have those two subwoofer RCA jacks, then it isn't a VSX-52.
How would not havine the LFE affect my home theatre experience?
Remember, LFE is the name for an audio track on a disc, not for a receiver's output. A receiver takes the LFE from the disc's audio and sends that audio to its subwoofer output(s) along with low frequencies from the other speaker channels. When using receivers or amps without a separate sub output, you would have to connect the sub to both the Left and Right front speaker outputs. This is when you'd need to use all the controls on the back of the subwoofer. This should not be the case for you.
BTW i have the sub jack plugged into the L out put does any of that matter?
If you mean that you've connected it to the Left Front preamp output, you'd get only the low frequencies that are sent to the left front channel, and not hear what is being sent to the Right Front speaker. If you've actually plugged it into the left-hand "Subwoofer #1" output, then it is connected correctly.
In a receiver which has no separate sub output, the option to set the front speakers either large or small isn't available.
Maybe you're looking at the wrong connections? Or not noticing the label "Subwoofer"? It's above and between the two subwoofer RCA connections. Here's a screengrab from the manual. I've outlined the subwoofer connections in red.
Thirdly, what exactly is sub EQ? I know that unlike some other automate room calibration systems, MCACC does not have this. Moreover, certain subs are coming with a like feature built in. Since i do not have either, what do you recommend.
Sub EQ (subwoofer equalization) is shorthand for the ability to flatten (make more accurate) the volume and timing of the low frequencies heard at your listening position which are coming from the subwoofer. It's an optimization which has become affordable only in the past few years. There are other, more traditional methods to improve the sounds you hear from a subwoofer. One is called the "sub crawl". Put the subwoofer where you sit when you listen to music or movies. Then play some calibration sounds and crawl around the room listening for the best quality sound (not the loudest!). Then put the subwoofer there. The sound travels over exactly the same paths no matter which direction it travels between those two locations. You should disconnect the other speakers while you do this so they don't mislead you.
Lastly, is the cross over frequency the reason why I do not hear my subwoofer during talking scenes and why it may go into standby during a viewing.
I believe so. From your description, your sub automatically turns itself off if there is too low or no audio signal coming in. Since it isn't sensing the higher volume upper frequencies, it's turning itself off. I believe that its auto-detection level is simply set too high, but that's not something you can change, unfortunately.
Prior to getting the receiver, I had my sub plugged directly into my TV, The TV had a sub jack. There for my sub was always on and I felt as thought I got good bass during talking scences. Now I feel as though I hear my sub in only action and music sequences in a movie. Is this because during all other moments in a show or movie, the frequency in what was being detected by the receiver was not low enough for it to send it to the sub to push out?
I'd describe it somewhat differently, but yes.
You need to change a setting on the back of the subwoofer. There's a switch at the top left on the back labeled "on/auto/stand-by". Change it from Auto to On.
The subwoofer is turning itself off because the low-frequency sound level coming from the receiver is just too low in voltage for it to detect most of the time. Unfortunately, changing the setting does mean that you'll need to remember to turn the subwoofer off when you're not watching TV or listening to music.You might want to consider getting a separate power-strip which has an on/off switch, since I don't see a power switch in the picture of the speaker's back panel, and I suspect the Auto switch isn't designed to be changed frequently. (The picture is too blurry for me to determine that.)
