You could get a subwoofer first and then if you have any money left get 2 pizzas. 🙂

Here is another pretty diagram for all the members (99.99%) that don't care about diy speaker wire to RCA for powered subwoofer amplifiers. This doesn't require any modifications to your main speakers with internal crossovers and has added protection in case a resistor gets shorted. Of course you can buy them for about the price of a restaurant pizza - Russound makes a nice solid one that retails for the price of 2 pizzas. If you haven't purchased a subwoofer yet there are very good ones that have speaker wire inputs and then you can just ignore this babel.

No need to get to the crossover inside the speaker to accomplish the objective, it can be done with a lot less effort using an extra wire attached to the amplifier's speaker outputs or the speaker's inputs and then to the sub amp RCA inputs. Do you think everyone that buys a powered subwoofer with speaker wire inputs has to open up their main speakers and attach a wire to the crossover low pass? Absolutely not necessary, but if you happen to have speakers with external crossovers it can be done your way without extra effort, but with internal crossovers it is......certainly not hitting the easy button. Here is my complicated way, whatever you do don't do it this other way that is easier. (where is the hitting your head against a brick wall emoji?) You still don't seem to get that some people are not inclined to diy such things and what is needed can be bought already made and ready to use for very little $.

"you should be able to tap the speaker's crossover's low-frequency output to feed the sub." That's a real head-scratcher, sounds way more complicated than needed to diy speaker output to rca in. I wonder why subwoofer manufacturers haven't thought of doing it that way?

"My apologies--sorry for suggesting something as unreasonable as using two resistors and coaxial cable to inexpensively provide a solution." There are inexpensive speaker level to line level converters that will do the job for those without the tools and/or knowledge to diy.

"The limitation is now only lower cost subwoofers come with speaker level inputs." ??? You don't know the subwoofer market.

CL listing ended and I went through the thread but didn't see an asking price.

True and you must really dislike someone if you tell them they don't need to, at the very least, replace the caps in an old one.

Loudness on? Treble turned up? Woofers distorting but you don't notice it? One person's turn it up a little bit is another person's turn it up a lot. Ever check SPLs? 45w receiver to 100w AVR is not a huge difference. There is a review with a 25w integrated used for music listening and tweeter distortion was not mentioned. I don't trust 40+ year old amplifiers with original power supply caps.

My grasp of that is fine, it's the posts I see where others say or at least indicate it is perfection. And even though I didn't quote it my response should indicate I had this in mind: "Big speakers small room better than small speakers small room 8-) I love using big speakers as headphones. If the room is a compromise why compromise the speaker."

Does any company make 3-way headphones? Why compromise the sound even more by using speakers that are too large for a room? Horses for courses or something like that.

Guy is asking basic questions about subwoofer hookup and you are suggesting something less than 1% of the small number of people in this hobby are willing to do because there are easier ways. smh

The tape out can be used as well, but it is not fun adjusting the subwoofer every time you adjust the receiver volume especially if the receiver/integrated has a remote. 👎

Not compatible unless you get a speaker level to RCA level converter. Dayton Audio makes a few inexpensive powered subwoofers with speaker wire inputs.
