Victor - I peeked at the manual for the sub, and found this: "If your receiver or processor only has a single subwoofer line output, either the left or right input jack can be used. The loudness of the subwoofer will really be a function of the built-in amp. Hope this helps! Kyle - I'll see what I can do. Question 1: I don't have any hands-on experience with that sub, but it looks like it has the usual LFE inputs, so you can try it with that cable, though typically a sub only needs one input from the subwoofer output on the receiver if it doesn't sound right, try unplugging one side of the Y.

Question 2: A subwoofer output is sending only signal, so if the amp it out on the Mythos, you won't get any power from it and I'm not sure it would work anyway.

Question 3: Without knowing the dimensions of your room, it's hard to say which speaker would be better on the sides or in the back. The s have a slightly bigger woofer, so it may come down to your personal preference as to whether you want that punch coming from the sides or the back.

Louis - If you're in the process of upgrading your receiver, and want to keep that subwoofer, you want one with a dedicated subwoofer output. Here is a link showing home theater receivers with subwoofer outputs.

Hope that helps! Christopher - I feel like the subwoofer output to the LFE input on the subwoofer should give you what you're looking for, but it doesn't sound like it's working the way you want it to.

The only other thing I can think of is to make sure the crossover on the sub is set properly to pick up where the Chora speakers leave off. To get really hands-on, methodical diagnosis, it would be best to talk to a tech support rep on the phone so they can walk you through a few scenarios. Thanks for the question!

Dennis - To my way of thinking, the subwoofer should pick up right around where the front speakers stop, which you indicated is around 50 kHz. I don't think I'd mess around with the phase unless you experience it as sounding "off.

However, another method is using the left and right inputs RCA connectors in which low frequencies are sent through the right and left channels.

Realistically, you probably will not have to use the L and R inputs if you are using the more common LFE cable option. However, these inputs can exist on the subwoofer whether the device has an LFE cable option or not. Especially if you are new to the audio world, like if you are just bringing in new equipment to set up a new home theater, then you might be confused about all of the varying acronyms.

It all seemed so simple before you began attempting to connect the cords to the right spots, right? You might know that LFE stands for low-frequency effects, but what does that actually mean? In brief, LFE cables connect your subwoofer low-frequency speaker to its receiver. Since the subwoofer is responsible for low bass tones aka its sole purpose , it requires a transmitter of low-frequency audio waves.

The left and right channels are combined in an LFE cable to allow for a singular cable to evenly disperse the signals to the subwoofer. More than likely, you will use an LFE input cable for your subwoofer connections. In this day in age, it is far less likely that you will use left and right input, though this is not out of the realm of possibilities. Most people have found that using an LFE input in a subwoofer will carry the appropriate sound from the subwoofer to the receiver and, thus producing the effective audio.

The sole purpose of the subwoofer is to emit the low-frequency tones think of the deep bass in voice-overs during a movie, or the low bass that you can hear in a car driving by. Since this is the case, the subwoofer needs to receive the audio signals intended for this speaker to produce: the lowest frequencies of an audio production.

The LFE input in a subwoofer allows for this to be done simply through one standardized connection. Rather than having to sort through various cords and cables, you can use an LFE input as a single cable to connect your subwoofer to its receiver. This can help to eliminate the confusion about which cable goes where. But, again, this is the more common and preferred connection method, so it is likely that this will be what you are used to. Contrarily, if your subwoofer does not have an LFE input connection, then you will find that your option is to use RCA Radio Corporation of America -right and left- inputs for your subwoofer.

Though this is not as common and is often less preferred because you will have to use two cables instead of one , it works well and can achieve the desired result. RCA cables use a right and left input cable or split these with a y-cable to achieve the digital transmission of low-frequencies for right and left channels in a subwoofer. Instead of combining these audio signals, as does an LFE input cable, the RCA inputs these in specific locations: right and left input options connecting the subwoofer to its receiver.

To utilise the LFE channel in the correct manner would mean that you connect a single cable to the LFE input on the subwoofer.

You should also dial the crossover control low pass filter on the subwoofer to the maximum setting. This is due to the fact that in LFE mode, the AV receiver or pre-amp has already taken care of this for you. The left and right inputs on a subwoofer are actually designed to receive a full range stereo source.

This is when the crossover setting on the subwoofer would need to be calibrated according to the rest of the system environment. In this scenario, the subwoofer can filter out the low frequencies and then pass on the higher frequencies. In almost all cases, a single RCA subwoofer cable would be the correct choice for your home theatre system.

Some subwoofers may indeed display an increased volume output level of 3dB when a Y adapter or cable is implemented. However, this does not increase the maximum potential output volume of a subwoofer and only serves to bring the subwoofer 6dB closer to clipping the internal preamp and 3dB closer to reaching the dynamic output limit of the subwoofer.

The exact same effect can be gained from adjusting the volume control. Some manufacturers claim that their cables are directional must be connected to the source with the arrow pointing outward. With the exception of active cables these feature an integrated circuit , in almost all cases this is a false science.

As the cables which form part of a home audio system handle AC Alternating Current , this fact alone should put to rest any claims of a directional cable. As the name suggests, AC basically means that the electric charge flows in an alternating direction and not in a single direction, as would be the case with DC Direct Current.
