    I have noticed a few things since putting this sub into use. I have always heard a subwoofer goes through a break-in period. I never knew if this was true or not, but after what I have witnessed with this sub, I think it's true. The sub's output increased with use over the first few days of using it. The increase wasn't huge, but it was enough to notice a difference. Thanks to wogg's suggestion of using a Y cable, this also made a noticeable difference in output. I now actually have the volume control on the amp turned down a bit. I no longer feel that a line driver is necessary. In fact the other day while watching movies, this sub was rattling pictures on the wall. I'm completely satisfied with it now. I appreciate everyone's input...

    I do have an RCA "Y" cable...I plugged it in and I'll see how that changes things...

    The only thing I set was the low pass Xover, set to 80hz...everything else was left at it's default setting...

    I posted that info for people trying to help you. Like Wogg.

    ^ if he doesn't have a splitter he can take a single RCA cable and plug one end into the LEFT Unbalanced RCA Line OUTPUT jack and the other end into the RIGHT Unbalanced RCA INPUT jack and get the same solution.

    I checked out the manual, pretty simple. I'm sure you've messed with the subwoofer volume control on the remote as well as the master volume. The single RCA output should go the the left input, a Y adapter to connect to both R and L on the sub side. will boost level by 6dB to the sub.

    If that's too quiet still the line level booster you found will help.

    I think the Talent might be discontinued. Sorry.

    The other extreme is the Radial J+4 as a line driver, but about 3x the cost of the ART.

    Wolf, I think the cleanbox would work, and nothing comes up for the item #233-168. The LGB-1 is only $45, whereas the Cleanbox is $89...

    It is not the same as the LFE/Sub output of an AVR. For one thing an AVR can adjust the outputs to all the speakers and the LEF/Sub output independently. Most AVRs also boost the LFE/Sub output by 10dB.That's why I asked if you have an AVR. I guess not.
    This sound bar has a separate volume control for the sub. I don't know if it has any boost, I haven't been able to find out any info on that. I'm guessing it doesn't, which is probably why the signal is so low.
