Subwoofer & pre amp


I like JL Audio subwoofer, had F113 for a brief period and thought it was better than Rel B1 & Stadium I used to own.

I now have a pre amp with only 1 set of output; JL only takes line leve input and no speaker level input. Short of using a Y-adaptor which will degrade sound more or less, will I be better off getting a Velodyne DD or Rel again? Either one will be physically larger than JL whcih could be an issue.

This sub will be 30% music & 70% HT, I normally don't use sub for music but like to have that option.

Raul,

I have only 1 set of pre out from my pre amp, the other two outputs are all line out which is fixed in output.

JL F113 has both fixed and variable input, but variable does not mean I can feed it with line out from my pre amp as I will need to adjust volume on JL F113 for every piece of music. not a pratical solution.

my best option is to build a voltage divider and feed JL F113 directly from my power amps, there are no other alternatives unless I use a Y-adapter.
My Preamp has 2 sets of outputs. I am also using a JL F-113 with it. The sub is an awesome unit.

Anyway, consult the manufacturer of your preamp. I would say though unless your preamp is a tube unit , using an external Y connection should be fine.
