Help in hooking up a sub woofer.

Hi, I have a PrimaLuna ProLogue integrated amp.I have a pair of PSB Synchrony 1B's which until now I have enjoyed very much.
(I have a small living room)I just bought a PSB SubSeries 150 (subwoofer) but when I got it, I knew I was in trouble.The sub has "only" RCA jacks. My Amp of course only has the speaker terminals and no other dedicated Sub  hookups.What is a bit irritating is the PSB "Owners Manual" indicated you could attach speaker wire to the sub. I then discovered they use the same manual for all their subs; possibly some of them do.Does anyone know a way to connect the amp and the sub? And would it be a method you would find acceptable or is it a horse it in job?Thanks for any and all help.

Hello 246810,

     Well, it seems like you're not going to buy a decent sub anytime soon due to your lack of space.  Maybe I'll respond to a future thread you post when you're ready to add a sub or two.

Good Luck,
Tim

What you need is a speaker level to line level output converter:

It is just a simple voltage divider, contain two resistor in each channel.

246810,

     This is a viable option but it's not needed if you buy a sub with speaker level inputs, like either of the $500 SVS subs.  $40 you don't really need to spend plus the extra hookup complexity.  Why bother?
