Well the the sheet rock is up and I couldn't resist a test run and I'm happy to report that the setup passed the test with flying colors. I went with option #1, bypass pre-amp, so everything is controlled by the new AVR. I needed to increase DB output on the the new AVR sub control to get satisfying sub output.

Thanks again for the help.
Glad to hear (pun intended) you are pleased with the results!

M-G,
1). Yes, volume will be controlled by the Denon.
2). Should not be a problem since you are using the Denon's subwoofer output. Therefore, the Denon will already have applied signal filtering/bass management IAW the crossover and other instructions you program into the Denon. However, like any new setup, I would begin with low volume, ensure all sounds OK, before a full-up test using your favorite bass track or action flick.

Thank you again Shamu. Exactly what I was looking for.

I will report the results here when it's all set up. The divisions and electrical are done. I'm currently in the process of installing the backer boxes for the in-walls and passing the low voltage wiring.

Sorry for the late response, but hey thanks Shamu for the crystal clear explanation. I will definitely be trying this out. Yeah the VSX-D1S was regarded highly when I bought it. I paid well over 1k for it 20 years ago.

1). I think I will be trying option #1 using directly the amp. If I understand the difference, it means that the VSX-D1S will only be used as an amp and volume will be controlled by the new receiver (Denon avr-x4000).

2). Do you have an opinion on the lack of a HPF for the subs?

P.S. The old reviews I found online for the VSX-D1S spoke very highly of its power amps and it should be able to power your passive sub quite well.

I'm set on buying a pair of 10 inch Monoprice passive in-wall subs and I'm not sure if I could use my old receiver as a dedicated amp for them.

Here's how I understand it but I'm not sure if it will work or if there's not a more suited solution as I have never done this before.

So I would be connecting both subwoofer outs from my new receiver (presumably a Yamaha RX-A830 or another similar 7.2 receiver, I have yet to decide) to two rca inputs on my old Pioneer VSX-D1S. I'm guessing I would need a "Y" splitter to split the subwoofer out of my new reciever to connect to both left and right inputs on the old receiver. On the attached image I would be using VCR 1 and 2 inputs on the old receiver as signal in.

Then I would use speaker cables to hookup the front speaker output of my left and right channels to each of the two subs.

I would then set the old receivers volume at a balanced volume and leave it there using the new receiver for general volume adjustment (including the sub).

I'm no expert so any input is appreciated.
M-G,

You are making this too hard.

Referencing the picture you provided (thanks BTW) near the center of the picture are two sets of jumpers from Pre-Amp out to Power In with the bottom set labeled "Front Amp" (I can not see the label for the top set).

To use this AVR purely as a sub-power amp (i.e. bypass pre-amp):
1) Remove both sets of jumpers.
2) Run one RX-A830 sub-out (subout#1) through a Y-splitter into the Front Amp Power-In L/R input and the other RX-A830 sub-out (subout #2) through a Y splitter into the upper (label?) Power-In L/R inputs. These connect directly to the AVRs power amp section bypassing the pre-amp section.
3) Then connect speaker wire to the set of amps/speaker outputs these two Power-In inputs support and you are done.

If you want to use the pre-amp section:
a) Don't remove the jumpers. You will only need one set of connections; i.e. subout #1 into the L input of your choice (i.e. VCR 1) and subout #2 into R input of the same set (i.e. VCR 1).
b) Then select an "all channel stereo" mode (assuming the VSX-D1S has one) to force the AVR to output the sub-signal to two sets of AVR amplifiers (i.e. L/R Front and Surround L/R).
c) Connect speaker wires to these speaker outputs.

Post or PM if I have left these waters too muddy

Cheers,
Shamu

willis7469 I don't believe the denon will do any hpf out of the LFE. That's mainly what I meant by my suggestion of the in line thing. I used caps to reflect how I MIGHT say that vocally, indicating they might be a last ditch effort. My thinking was that since you won't be using a "sub" amp that it would not have a subsonic filter, to protect your drivers. The part that's above my pay grade is, the freq response of the "VCR" inputs might only be 20-20k. I'm not sure what would happen to content below 20hz.

Re: Help with dual passive sub hookup to old reciever

No receiver has a HPF on the sub out. Most subs have that built on the plate amp. In your case you wont have one unless you get a proper external amp with one built in.

Given he has a new Denon 4520 sitting and waiting to be used he is good to go on that end
Are you saying that the sub out on the Denon x4000 does HPF? I read that it's there for the amplified outputs.
