I needed a y type connector and after getting the wrong one at Wally-Mart (3.5mm audio plug to two RCA male plugs). I returned that and went to the Source. They still had an older one male RCA plug to two male RCA plugs connector cable. Just what the doctor ordered. Base now sounds fine without annoying pops or hum. That's good except the Y connector should have one *female* RCA and two *male* RCA plugs unless you also used a female to female coupler. I think that's what you meant.---This email has been checked for viruses by AVG.https://www.avg.com

He did mention that he had a "cable assembly" with 2 males on one
end and 1 male on the other.

That is what he said and I sort of understand it but I hope he doesn't
mean he fed the combined left and right channel "out" into the sub
woof "in". He has a mono now if he did because they are shorted
together.
I haven't really been following this that closely tho. My eyes glazed
over when they started talking about stereo systems approaching 10
grand. That is a nice outboard, that sounds better than any stereo to
me ;-)



No. Most 5.1 and 7.1 receiver/amps have a single RCA "subwoofer" output
that passes the combined bass from both main channels. Bass isn't
"directional" so there's no need for two subwoofer outputs.

Most powered subwoofers (at least the ones I've had) have *two* line
level inputs. Sometimes one is labeled as "LFE" (low freq effects)
and the other is usually not labeled. For best performance overall,
you put a "Y" connector that feeds the single sub-out on the
receiver/amp to *both* of the line level (female RCA) inputs
on the sub.

OK that makes sense now. My sub woofs only have one "in" but they
don't cost as much as a good used car. ;-)
It does explain the Male to Male/Male tho if the cable is long enough
to connect both components.






Yeah, when I was looking for a picture of a "Y" connector I noticed that
some receiver/amps are now including two sub-woofer outputs instead of
the typical one. The reason is to allow having two subs shaking the
room instead of one. People tend to get carried away with
bass, IMO. Other than rap music or movie special effects the bass
should be more subdued than what most people set it at.

I have one here next to my chair, hooked to the TV but I don't crank
it up unless we are watching a movie that benefits from it. I can
bother the neighbors if I want ;-)
My wife has the sub woof set to high in the bedroom IMHO and sometimes
regular TV shows rattle the windows. I notice it more in the other
room because that base travels through the whole house and there is a
block wall between us.

I read an article on how to build a media room. When building a new house or doing an extensive remodel, you decouple your media room from the rest of the house. It's mainly putting in twice as many 2x4's in the walls (8" centers) so that every other one is offset an inch or so side to side. What that does is allow the sheetrock on on side of the wall to be fastened to 2x4s that are not the same 2x4s that the other side of the walls sheetrock is fastened to. The walls are decoupled, and with some insulation installed in the middle, the sound does not propagate through the wall nearly as much as normal. If you were building a new home and money wasn't an issue, apply the same principle to the floors and ceiling and you have a really quiet media room for both the peeps in there and the rest of the house. Cool concept.
