Cable for my Rythmik F12SE Sub

One serious bass aficionado I've met on the Planar Speaker Asylum uses 6 or 8 gauge housing wire (Romex, etc.) for his Magneplanar Tympani T-IV bass panels! He powers the panels with a Crown Pro Amp capable of delivering over 2,000 watts to each Tympani's 4ohm load.

Hello again bdp -
I actually used some Romex initially (leftover standard 12 gauge stuff from in-wall house wiring for 20 amp service). I’m running the subs connected to the terminals of my speakers and positioned alongside each so I only need a short run. I couldn’t get a good purchase tightening down on the bare wire ends of the Romex so I switched to doubled-up lamp cord that fit some spades i had. Doubt I’ll hear a difference but would like to pretty things up while keeping the cost as low as possible. The Kimber 8PR is pretty affordable: 5 foot, unterminated, single run (I can cut it in half) under $60.

I’m thinking Romex might be a wise choice for delivering over 2000 watts.

I have assumed I would at some point try the Kimbre 8PR (I already have KCTG, KCAG, Hero, Silver Streak, and PBJ interconnects, and 4AG speaker cables). The Tympani's have those darned Magnepan connectors, for which I'm planning on getting a set of the Magy Pins Cardas offers. There is a guy making speaker cables terminated in those pins and selling them on Audiogon, but he wants about $300 for an 8' pair. Relatively cheap for full range cables, but for subs more than I would want to pay. I still have a NOS pair of Tara Labs Space & Time Phase II 12g cables I want to try as well!

Sounds like you are pretty well invested in Kimber...does that mean you've been happy with them?  

I have a pair of 12" Rythmiks in very heavy DIY sealed boxes. And B&W 804S.

Try running the preamp line out into Rythmik's crossover, take the line out of the plate xo and feed your amp. Your amp and your speakers will no longer try to reproduce signals below 80Hz. You will need to adjust the PEQ controls to get optimal response. If you have means to measure, the better.

This was an eye opening experience for me despite my hesitation from being a purist. My preamp was a Lamm so I was assuming  the cheap xo in between would suck.  It didn't!

That was the beginning of my journey into an active system. No looking back for me.
