Cable for my Rythmik F12SE Sub

spoutjack's original question made it unclear as to whether he was asking for a high level/speaker cable recommendation, or a line level/RCA jack cable one for use with a Rythmik sub. My question was intended to get clarification because Rythmik subs are available with a choice of two basic amp groups: 1- the PEQ version, with both RCA jacks/line level inputs AND binding posts/high level inputs, or 2- the XLR version, with both RCA jacks/line level inputs AND XLR/balanced line level inputs but no binding posts.

Brian Ding of Rythmik recommends using the RCA or XLR jacks/line level inputs in preference to the binding posts/high level inputs whenever possible. Other sub makers and users, particularly REL I believe, recommend and prefer speaker level hook ups. The Rythmik PEQ amp allows both, the Rythmik XLR only line level, not speaker.

For hook up to a Rythmik via speaker cables, one is free of considerations other than bass/low frequencies, so a regular speaker cable known for it's good bass reproduction is an obvious candidate. Some cable companies make cables specifically for subs, but I've never tried one, as all my Rythmik subs contain the XLR version amp (370w and 600w).

Sorry for the delay in responding ghosthouse, I was away from home on a gig. I was pals with Brooks Berdan (R.I.P.), and we had a nice mutually beneficial arrangement wherein I would provide him with vintage drums at my cost (I was dealing in the 90’s and 00’s), and he me with hi-fi. His choice of cable brands in his shop were Cardas and Audioquest. I didn’t find Cardas particularly of interest (I find George’s cable theory somewhat specious), and didn’t know much about Audioquest. On one trip with Brooks to CES in Vegas (as a Brooks Berdan Ltd. "employee"), I bought all my Kimber cables at industry-accommodation prices. I was looking for high transparency and extended high frequency bandwidth, which the silver Kimbers provide.

I am not what is viewed as a typical audiophile, always thinking of change in pursuit of (hopefully) improvement. The Kimbers I have are good enough for me and my modest system (by Audiogon standards!), and I have no burning desire to look for better. The only cables I’ve bought since getting the systems worth of Kimbers are 1- a pair of Clear Day Double Shotgun speaker cables (all silver), necessary only because I moved from dual mono power amps to a single stereo one. My Kimber 4AG speaker cables are only 1’ long! The Clear Days work perfectly with the Kimbers, being more alike than different. And 2- the Kimber Hero interconnects for my more recently-added subs---GR Research/Rythmik OB/Dipoles in H-frames, Rythmik F15HP’s (DIY in 4cu.ft. enclosures), and now Magneplanar Tympani T-IV’s (for both full-range use, and the bass panels as woofers for my other speakers). The Hero’s have a great bottom end for a budget cable. No need for an expensive cable with an excellent midrange and high end when it will be reproducing bass only, ay?
