Question on additional subwoofer set up

[CarsandCigars]

I currently have one VTF3-MK5 sub located in my dedicated theater room and am looking to get a second one as well. I have a Marantz 6007 AVR and am wondering if I hookup the 2nd sub to the 2nd sub out from the receiver, or if it would be better to have it inline with the current one already hooked up...hope the question makes sense the way I have written it.

Appreciate any feedback or recommendations anyone has.

Hi there,

I recommend running the second VTF-3 Mk5 HP on the second sub preout, especially if they are discrete channels where you can adjust speaker distance independently between the two subs. That would help open up more options for placement and give you a better chance of smoothing out the response at your listening position.

Kevin,
two questions,
1. If I use XLR do I need to use both the righ and the left channel inputs or one would do as my Parasound Halo Integrated only has one XLR output for Subwoofer

2. I have separated my HT from 2 channel listening , the question is if I connect the VTF -15 with" one" receiver via XLR and the "other "pre amplifier with with RCA inputs , but only listen to one or the other , not both at the same time in other words I turn one system off and use the other would that work ?

1. Nope! If your integrated amp has a balanced XLR for subwoofer, just use a single XLR cable to run to either the left or right XLR input. Doesn't matter which one.

2. Let me verify with Dr. Hsu tomorrow. However, if I remember correctly, some sub outs still introduce a high impedance so that as soon as you connect that RCA to the sub, your level will drop dramatically. So it may not work in that case.

To answer #2, Dr. Hsu did agree that depending on how your receiver handles the sub out, turning it off may still introduce a high impedance that will decrease the output from the high level inputs. Some actually short the pin to ground, so you may not get any output at all. If the sub out creates an open circuit, then it should be fine operating it in that way. However, what I would do, if that is not the case and it is one of the first two scenarios, is I would put in an RCA switch box in there so that when you are not using the receiver, you can disconnect it by the press of a button.
