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:

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.


Just taking a quick look at the manual, I would agree with mofi's response, however, if you look at features here,

http://musichallaudio.com/old-products-a15-2/

it states that the line out is fixed. This means that the signal is not controlled by the a15.2 volume control. Even though the sub would play, it's volume would only change by using the sub volume control.

If the line out is variable, it will work great as mofi described, and the manual seems to imply it is variable, however the website says fixed. If fixed trying to use a sub is not a good idea.

Looks like you need to contact Music Hall.
