High level speaker amp out to RCA


Hello community.

Many preach, including REL,  that the best way to connect a subwoofer is from the high level speaker output from the amplifiers so the sub receives the same "signature" sound the amp sends to the speakers. This sounds quite logical!! My subs only have RCA inputs, how can I go about this type of connection? Is there a good high level to RCA thingamajig?? Any suggestions??

 

Thank you for your constant guidance!!

Seems like its not that straight forward.  I there an external adapter/converter that is just plug and play??
I recently purchased a new(used ) tube preamp. It does not come with extra set of 'outs' for a subwoofer connection. My subs are RCA level input only, so I am in the exact same predicament. 

I have a friend who designs some of the world's best loudspeakers who, taking pity on me, has agreed to put together the right package of resistors to make my speaker level connection into a line level with some spare speaker cable, some resistors in series and and soldered RCA plugs. 

Its not done yet but I can hit you back with the design and reports of how it works when I get them. 

.. More to come.

It is a voltage divider that erik_squires referring to:

attenuation: -30 dB, should be safe to connect to your subwoofer.
