(1) The subwoofer is connected via long run RCA terminated ICs from the preamp outs on the integrated and plugged into the active subwoofer amp matched inputs.
(2) as far as sonic signature goes,many quality build subs will perform yeoman services. REL is just one brand in a "pick 'em" arena.
The main consideration that I and my cronies have experienced is to pick a quality build in the $1500+ price strata for 2 channel integration , but buy it used for a considerable cost saving.
The cheap subwoofer kit invariably can slide into wooly and boominess that can weather through the booms and crashes for HT soundtrack but is a sensitive irritant for 2 channel.
I have two subs - one for HT and one for 2 channel.
I was recommended to scope out the VANDERSTEEN 2Wq sub after the usual REL, B&W, LINN, and lengthy parade of contenders and pretenders.
My dealer recommended it, I auditioned it, I then compared it in an A-B inhouse shoot-out audition and I bought the VANDY for its superior performance.....FWIW....
