General speaker questions for audio and home theater.

RE: Speaker positioning - trying to use 4 speakers

To answer your first question about source. I mean whatever you are using for music playback. It doesn't matter what it is (and you won't get any judgments from me as to how you play your music...it's your party and you can Spotify if you want to).

What I mean is that both your Pioneer and Yamaha probably generate test tones to help make sure that you are getting the correct levels at the listening position. Those are great to use as a baseline. In fact, when I am setting up a system, I will start with those tones. But those tones are NOT coming from your iphone, or CD player or music server and until you calibrate using tones from the music source (again..whatever it may be) you're not getting your money's worth. I also try to go manual (using the sound level meter and setting the levels manually) rather than using the microphone some newer receivers come with. If your Pioneer is older, it probably wont have auto-calibrate anyway.

As far as amplification goes, I think you are OK with those levels. Keep in mind that the sub-woofers in the Deftechs are powered (assuming both those models are powered towers) and don't need an amp.

So if the Pioneer has 5 channels of amplification, I would go with that one. I had one of those big Pioneers back in the day and always found them a little too bright. Of course, that's a nitpick..they were great receivers, especially the Elite line. I wouldn't bother with bi-amping because you're looking at a lot of cable already and bi-amping will increase the amount of interconnects and speaker cables to staggering levels.

I would also, if your speakers allow, remove the jumpers to the low end (my BP-2002 have 3 sets of binding posts; high, mid and low) and use the Pioneer's LFE and/or sub output. That way the receiver is handling bass management and you have more control. If you only have the mid and high speaker connections, then you also probably have the LFE and/or sub input on the plate amp on the BP towers. Since you're not using the system for movies, and IF you have a choice, use the sub input rather than the LFE input, which is supposed to be for movies.

Always make sure the Pioneer is set to "large" in the speaker setup. Let the internal crossovers of the Def-Techs decide what frequencies go where. I would also call DefTech and ask where to set the bass management. They have some of the best customer service I have ever experienced.

The only other thing that made me worry when I started was what to do with 2 (in your case 4) subs and only one LFE output. Just get three splitters and make 4 outputs then run the RCA cables to each sub. Easy Peasy. I never did 4, but I didn't seem to have any problems with 2 and I doubt you will "degrade" the signal much if at all. You're not sitting by yourself in front of two speakers doing critical listening anyway, you're dancing and having fun. So relax and have fun. :)
