speakers and cables

@griz, going back a few posts--I don’t claim to be a bright light on this. But to me it just makes more sense to go from the L speaker post of amp into the L sub and from there in to the L speaker and then the same for the R side.

I don’t think there is such a smart crossover inside this cheap sub that would split the signal. I think the full signal goes out, but that’s just my assumption. I will post a question on the polk forum, it’s always very active.

Please post your findings; at this point I am quite curious and interested about this.

The Y splitters should arrive tonight, will be interesting how it sounds.

I am also curious about what you are going to hear when you experiment with that. Please post your feelings about what you hear. But I also think that your sonic perceptions may change as the new sub breaks in.

At this point I am embarrassed about a number of remaining questions, so I will just keep them to myself and play with it to try to confirm my assumptions...

I can relate to that myself (being embarrassed about some of my questions, that is), but a long time ago someone once told me that, "The only stupid question is the one you didn’t ask." But I am still frequently inhibited anyway, and people still make fun of questions that they perceive as being stupid. So I understand where you are coming from. However, I actually learn a lot from threads like these, so I personally benefit from these questions, so I personally hope you ask your questions here on A’gon.

Here is an example of a question I didn’t ask because I thought the answer was obvious and I was sure that some one would say it was a stupid question: whenever  there was a T’storm threatening, because when I put my system circuit in, the best place for me to put the outlets turned into a bit of a PITA, I used to just trip the circuit breaker for my system, but I was always wondering if a big enough surge could jump across a tripped breaker, but I thought, "Nahhhh, so I am not going to ask because I don’t need the derision." Then there was a "surge protector" thread on misc and that came up, and @JEA confirmed that a big enough surge certainly could jump across a tripped breaker. Now I unplug in bad weather, no matter how much of a PITA it is. But that’s just an example of a question that I should have asked but didn’t because I thought it was stupid.

As I often say: Ramble On. . . .

@immathewj one quick test: I unplugged the subs from wall, sub stayed dead, speakers still worked. Does it mean there is no crossover? Just wires? Active crossover requires electricity I assume....

No budget sub or expensive sub i’ve torn into has ever had anything for ’bass management’. If your sub has both speaker level in and speaker level out terminals, it is just a straight passthrough.

In a hi-fi application, you don’t want to use that lousy pass through terminal on a subwoofer into a speaker. You also don’t want to use a y splitter on any line stage analog interconnect. For low-fi, mid-fi and ASR-fi, anything goes.

@grizly, I am going to plead ignorance on that one at this point. When I came up with my crossover hypotheses I was basing it on the answer that @mitch2 posted earlier and then the discussion I found on another forum in answer to the question of whether a sub has a crossover. If the last answer you got is accurate, the speaker wire connection feeds a full frequency signal from the amp through the subs and to the main speakers. And if that is accurate, then I also ASSUME that the adjustable low pass filter on the back of the sub is also utilized in the speaker wire mode. So I guess if all that is true, the closest one could get get to having a crossover (for the subs) would be the high pass filter that I had been talking about in this thread, as it would cut frequencies off to the main speakers below whatever frequency it was set at.

So I honestly don’t know, if @deep says he has taken subwoofers apart, he has done way more than I ever have to them, and therefore would know way more than I about them, so if he is saying there is no crossover, I guess that’s the best I have to go on at this point. I’ll continue to watch this thread and see what else anyone might have to say on the subject.

After I took my aspirin, I thought deeper into my way of doing it and I don't think it will work. @grislybutter you're right in your diagram, that's what I was thinking.

The only way my way will work is if the output on sub1 sends the full signal to sub2, which it won't. It's low pass filter at the input I believe will stop the lows there and only pass on the higher signal through the high pass filter on its output to sub2 negating what having a second sub in the mix is for in the first place since no low Hz signal will be going to it.
