[How to connect powered subwoofer R-12SW to a stereo tube amp (2-channel) without sub output?]

Thank you @babadono and @tromprof. This is great news! Is the speaker-level to line-level adapter just 4 resisters? I have some resisters in my drawer to make a voltage divider for less than $1 😀 plus connectors. How dare can they sell that for $40? LOL Thanks a lot! 

 

 

 

[How to connect powered subwoofer R-12SW to a stereo tube amp (2-channel) without sub output?]

System Background info:

Main Speakers: Klipsch RP-150M

Integrated tube power amp: Reisong A12 

Subwoofer: Klipsch R-12SW

 

My problem is:

1. the integrated tube amp does not have sub output or pre out or LFE (only regular 2-channel 4 ohm and 8 ohm speakers outputs are available)
2. Klipsch subwoofer does not have high level inputs (only line level inputs are available)

 

My question is:

Is it possible to connect Klipsch sub to this tube amp without interfering the main speakers' performance and sound quality? I don't have a preamp. The tube amp has the preamp built-in. I plan to connect a cd/sacd stereo player to the amp input as the music source.

 

Thank you for any idea you may have!
