    I was reading reviews of my speakers(Energy Encore)and stumbled across this one. It basically says a high level connection to sub is the way to go for best bass and sound. Does this method not cause the receiver to work harder? What do you guys think? I've also read that you should NEVER hook sub up this way ! Getting more confused with more info. I get ! Thx for help.
    Summary:
    Proper hookup of the Encores will make a tremendous difference in your satisfaction. When I first hooked these up, I was not very happy. DVDs sounded pretty good through my amplifier, but music sounded downright terrible. I called Mark from Audioshop in Canada (where I bought them) as well as Energy customer support and was told the same thing...the only way to get great sound out of these speakers is NOT to hook them up in the traditional 5.1 setup (i.e. subwoofer connected to the amplifier via a subwoofer cable and all satellites set to SMALL on amplifier). Instead, the optimal setup for these speakers is as follows:
    * hook up the four satellites and the center channel to corresponding speaker posts on amplifier as normal;
    * use standard speaker wire to connect right High Level Input post on rear of subwoofer to FRONT RIGHT speaker post on amplifier. Connect left High Level Input post on rear of subwoofer to FRONT LEFT speaker post on amplifier. Do NOT use a subwoofer cable to connect the subwoofer to your amp. When hooked up correctly, you will have two sets of speaker wire running from each FRONT speaker post on your amp...one to a satellite and one to the subwoofer.
    * set front speakers to LARGE on your amplifier
    * set amplifier to indicate "No Subwoofer"
    * set the Bass and LPF dials on the front of your subwoofer (I set mine at 1 o'clock).
    * try it out!
    Basically, you are removing the subwoofer as a separate channel. Instead, your amp believes that you have a 3/2 setup with a set of LARGE speakers attached to the front channel and no subwoofer. Therefore, the amp will send a full (i.e. LARGE) signal to the FRONT speakers. The built-in low pass filter of the subwoofer filters out all but the low bass signal. The remainder of the signal is reproduced by the corresponding satellite speaker. Unfortunately, I found out about this after spending $50 for a premium subwoofer cable that I could not return (threw away the packaging/receipt). The setup above uses only standard speaker wire...oh well.

    Brad, by running high level, you do stand the chance for:

    1. greater signal loss by your signal traveling a longer distance.

    2. Poor quality crossover electronics that could degrade your sound to your mains.

    3. More connections in the mix, never best.

    I wouldn't recommend this for the highest quality to your mains. If you want to maintain the best possible signal transfer. Make it with the least connections possible, and the least length to avoid signal loss due to the signal traveling longer distances.

    That's my opinion, ymmv.

    Given then all the bass management is done digitally there's very little extra work involved...in other words this shouldn't be the reason you use high level signals over line level.

    Even if you use high level connections, the sub is still driven by its own amp, not by the receiver, so the receiver's amps don't work any harder.

    Maybe his receiver has a fixed XO point that isn't working well with his system, and the sub's XO is adjustable to a more preferable setting?

    That's certainly a possibility, but most subs I've seen have an adjustable low-pass XO and a fixed high-pass XO. OF course, it's possible that the high-pass XO on the sub is better suited to his speakers than the one on his receiver.
