Martin Logan 13A's with Rel subs? A match?


Hi , has anyone with the 13A's have them hooked up to REL subs? How do they sound? Was it a satisfactory jump? Are you using a single sub or a pair?

Was it easy to hookup? and how did you ground the negative wire on your amp? Floating? Chassis? etc

 

thanks

I have set several REL up with REL Speakon type connector.  Typically you will connect the Red lead to the Right Positive post , the Yellow to the Left Positive post .    If the Amp is a true balanced differential Do Not connect the Black lead to a speaker post, float the ground. Not all balanced amps are fully differential , ATI amps are and they make amps as an OEM for several companies it's.  If in doubt check with mfg.   You can damage an amp by connecting the Black.   If the Amp is single ended RCA and you get hum with the Black lead connected to a binding post.  Float the ground.  Ground to chassis with Black wire if in doubt, but check with Amp mfg

REL is usually a safe bet,   the key is not setting the crossover too high.  I just set up a S/510 for my Dad and it is a great sub.    The T series are good too , especially for the money.   

I have an older REL r 305 in my second system and it has been in use every day for the past 15 years. 

With your speakers I would recommend one of their carbon subs or an S/812.    Or two!
