Power Cables on Subwoofers do Matter


I read an opinion somewhere on this site that swapping the power cable on a subwoofer has a minimal effect and may not be worth it. I have a very different opinion. Power cables can completely transform a subwoofer’s performance.

I have an SVS SB-2000 powered sub and my preferred power cable, a Zavfino Fina, has made it sound like a different animal altogether. It has much more punch, freq response linearity, and liveliness. The manufacturer included power cable makes it sound slow, bloated, and almost out of tune just because it’s sloppy, in comparison. The only drawback to the Fina is that slam below 30-40 hz is a little recessed but it’s not major and is still clearly my choice. I also compared five other aftermarket power cables from other components in my system and they ALL had a different effect on the sub. For testing, I used various crossover points and most of the testing was with the loudspeakers off in order to isolate the sub for critical listening.

Too bad Zavfino doesn't offer a 90 degree IEC. Thats the only way it's going to work on my REL. With the REL in the corner behind the left speaker there is absolutely no room for a straight IEC back there. The cheap freebie just squeezes in there. 

Same with the aftermarket Signal Cable REL Speakon link. I ordered a right angle Speakon to put on it so it can fit.

@gladmo, the svs sub does not use the standard connector on their plate amp. I have the smaller SB 1000 Pro which uses a C7 I think it's called. Does Zavfino give you the choice of connector.

Also the Fina you mention is 14AWG which is considered a bit lightweight  for power amps. Why did you choose this instead of their 12AWG version? I realise of course that the heavier cable will cost more.

@gladmo -

     Based on your experience, as a musician: what percentage of knowing when the rhythm section is right, would you attribute to, "feel" (physiological/tactile)?

                       In both performing and listening scenarios, that is.

 

 

Never run SVS units with Teflon cables. The Teflon at high levels goes into helium gasified state that can work its way down into the driver motor thus giving off a burping sound around 85db. Careful out there!
