Amp's Line-Out to Subwoofer?

Hey Audiogon forum!

An audiophile acquaintance of mine has been trying to convince me to get a subwoofer for my system recently, and I am curious about the possible benefits. I have a pair of Elac B6's fed by a Music Hall A15.2 (which has no LFE out) and he said I'd be able to use the Music Hall's Line Out output to connect a sub. I have a lot of questions about that. Mainly (and obviously) will that work? Second, if it DOES work, will the full signal be sent to the speakers and would that create any weird complications in sound quality? I've never heard of doing it this way before so I have no clue; I just know that I love my current amp and don't want to get a new one just to get an LFE output.

Thank you!!

Also, here's the Music Hall manual which details the Line Out option in more detail:

I found the following comment about the a15.2 that was placed in 2012 at a different forum:
Two years ago they told me they screwed up production on these and hooked up the subwoofer out to the fixed volume instead of a variable volume, but it would be fixed in the future.
I see also that in the successor model, the a15.3, the corresponding output is labelled as a "pre-out" rather than as a "line out." Conceivably "in the future" might have turned out to be in the design of the a15.3.

Good catch by Tony (Tls49).

I will definitely be contacting Music Hall to see if this is a fixed or variable line out (does anyone know why the former would be of any use to someone?)
A fixed line output would be useful for connection to a recorder or to an external headphone amp.

Thanks Al, and ironically, that comment from the other forum is a little confusing. I assume they meant, it would be corrected in the future.

Good catch once again, Tony!  Until you pointed it out I hadn't even noticed the ambiguity of the word "fixed" as used in the last part of that sentence.  But, yes, I'd feel pretty certain the poster meant "corrected in the future."

Best regards,

I sent Music Hall an email and we'll see what they say. This got a lot more confusing than I thought it would... thanks again for all the help!
