Power Cords for Subs, any benefit?

I have an eel(se) power cord that improved the bass depth of my rel sub. More thunderous and dynamic response.

I've had many people report tighter faster bass when using upgraded power cords. I don't have a powered sub (soon to change) so this is all second hand. I think the same arguements for using them on an amp would apply to a powered sub. I noticed more bass that was fuller and tighter on my big SS Aragon and I guess the same could be possible with a sub amp. I would go to your local dealer and get something that can be borrowed or buy something with a return policy.

I switched from the stock cord on my REL Strata III to the Harmonic Technology Pro 11AC, and got an improvement in pitch and a feeling that the sub was exciting the room which was not there previously. The HT is relatively inexpensive, and I got very nice results, so you might start there, but consider spending a bit more and auditioning a few other brands, as the Aeriel is quite an exceptional sub, and deserves the best you can afford. Good luck!

Have experienced results as stated by Bigboss using the Eels on a pair of Rel Stadiums. I believe the reasonably priced BMI Whale will perform very well with the very good Aerial Sub. The Eels made the very good Rel Stadiums even better.
