Hello, I just joined, primarily for the audiophile products. Looking at purchasing the NHT C3 speakers for our new living room. Space is about 15 feet wide by 33 long and they will fire long ways. Space is just for general listening, music room with all equipment is downstairs, so hoping they will fill it with sound nicely. Cheers.

----- As an aside:
Andrew was suggesting a BNC ended coax cable (need 2) https://www.digikey.com/product-detail/en/pomona-electronics/2249-Y-12/501-1821-ND/736317 (various lengths possible but going short 12") along with a BNC to RCA adapter (need 4) https://www.digikey.com/product-detail/en/cinch-connectivity-solutions-aim-cambridge/27-8110/367-1012-ND/385337
Alternatively, for the DIY crowd... RG223 coax -- https://www.pasternack.com/flexible-0.216-rg223-50-ohm-coax-cable-pvc-jacket-rg223-u-p.aspx
I'll try this analogy. Not sure if this is perfect, but here goes: Think of tying a 3" dia. 18' rope to a Costco ceiling 20' above (an impedance termination mismatch), then lie on the floor under the rope and move the rope end back and forth 2' faster and faster until you see the middle start to bow out back and forth - a standing wave (reflection with constructive interference). Call this freq the fundamental resonance freq of the rope and note how the rope itself is starting to actually pull your hand (the source) back-forth due to the standing wave - i.e. presenting a problematic impedance for your hand to move your hand as you desire (causing overshoot or undershoot, perhaps). Then shake it faster and faster, and observe as the standing waves magnitude reduces (reflections still present but not as constructive, easier to control with your hand), followed by a return of more dense standing waves at multiples of the fundamental freq and difficult to control again. Ok, so this establishes that mismatch of rope impedance to termination impedance is problematic for the source when near or above the rope's fundamental freq. Next, shake the rope end the same 2' distance back-forth but way slower: 1/1,000th the frequency. No more standing wave, and no fighting the rope standing waves to move your hand. So we can say that exciting the rope well below its fundamental freq means the impedance matching of rope to ceiling termination is no longer useful in predicting how it loads your hand.
I wonder how a portion of the audiophile community here might react to your take on 'high-performance' cabling?! ;p Nevermind. ;) Cheers.
