Looking for advice on what to use for a long subwoofer cable run (~45’). An associate in a local retail store told me to get a good shielded coax cable and use “F to RCA” connectors. Or should I get two 25’ subwoofer cables instead and connect them through a female RCA adapter? Which will provide the best sound -- or reduce the chance of signal loss?
This cable run is for the back of my theater room. Still haven’t decided on putting 1 or 2 subwoofers in the back to complement the powered mains in front. Will it be best to go with 2 subs or is that not necessary? If 2, should I use a Y splitter at the receiver and run 2 cables or run 1 cable from the receiver and split in the back of the room? Or, run 1 to the first sub and daisy chain to the 2nd?
It isn't clear to me from your post, whether you have a sub(s) currently. If you do, have you experimented with placement yet? Or, if you don't have a sub, are you planning to place it/them at the back of the room because of space issues? If you have some flexibility with placement, perhaps you should try different spots, before deciding on final placement. As for connecting them, I agree with GR.
As for going with a single or dual subs, duals
can certainly enhance the SQ of your bass. But if it means buying two mediocre subs, instead of a single superior sub, you will probably be better off with the single.
There is no question that more $$ generally buys you higher output and extension, but dual subs can even out the FR created by room modes. It's a balancing act, I suppose.
