Pioneer VSX-520-k / Klipsch F-30: Help!!!

post #1 of 2
Thread Starter 
Hello all!

(really not sure where to post thise since it's about both amp and speakers :S)

I really need some help for something I don't understand at all, and I will try to give as many details as possible. I am an audio noob so bear with me :P

I had my Pioneer VSX-520-k amp for almost 2 years now and the whole time I never had speakers hooked to it: was only using it with my headphones to play my games and watch my movies.

Recently I finally decided to buy a pair of speakers after shopping for a couple of weeks and stopped my choice on a pair of Klipsch F-30. Was expecting great results since I heard a lot of good things about them from all the reviews and topic I read.

But unfortunately I am not super satisfied, and here's why.

For the 2 years I used my headphones (which are noise cancelling and a quality pair) I always had a great sound: receiver was always setting itself to STEREO (of course) since headphones were plugged in and everything sounded really nice, no matter if it was a movie (bluray) or games. Background music, voices, explosions, footsteps, the wind, etc.: could hear everything, nothing was drowned by another sound or frequency at the same time (or whatever it's called).

But since I bought my new F-30 something's wrong: I can play the same sequence (let's take Gears of War 3 here) and it won't sound the same AT ALL through the speakers vs. my headphones. With my HP everything sounds great: voices are loud, gunshots are punchy, footsteps in the grass sounds clear and crisp, I can hear EVERYTHING, nothing's missing.

With my new speakers it's just not the same at all: with the same sequence (above) some sounds seems to be either missing or are very VERY low compared to the rest... Like my previous example: gunshots sound distant and weak and footsteps in the grass are barely audible... It feels like half of the sounds are still there and playing nicely (explosions, voices) but another half is either missing or faint (gunshots, footsteps).

Now for the current setup: Everything is connected to the receiver through HDMI and a single HDMI cable goes to the TV for the video signal. Speakers are both in a corner of the room facing my couch 9 feet away (45 degrees angle). Each speaker is around 9 feet away from the receiver, total of 18 feet distance approximately between the speakers. They are not phased out (double checked the connections like 5 times) and I have a feeling that the problem might be my amp and not the speakers. When I say the problem is the amp I mean something's probably configured the wrong way, in the options I mean. Tried every single option and although it does modify the sound a bit it is not enough to see a real different and fix the problem above: ALC, Stereo, Pure Direct, Auto-Surround, disabled the surround speakers and center one since I'm only running 2, etc I tried everything. I know I don't have the best amp out there and it's a low-end one and I'm actually also wondering if maybe the amp is just not good enough for the speakers or something like that? But again it would sound weird too in my headphones no?

So for whoever has this amp, or can share some light on the situation: WHAT THE HELL IS WRONG?!?!? Lol I'm going to loose my mind here :P Had to play with my headphones the whole weekend because I just wasn't satisfied with the sound coming out of the speakers, and really stresses me out since I just paid a hefty sum for them

Any tips, recommendations or ''try this'' will be very appreciated: I know I have nice speakers and want to get the most out of them. Just not happening right now...

Make sure that the TV's speakers are turned off, by the way, just in case your receiver happens to be one that passes audio to the TV through HDMI when headphones are not plugged in.

If I'm reading this right, that's a total of 90 degrees from the listening/viewing position, which is more than is usually recommended for home theater/gaming (45 degrees total) or even music (60 degrees). Corner placement is also rarely if ever ideal for good sound (generally muddies bass and results in loud reflections from the walls). While I doubt that this has anything to do with the issues you are experiencing, I thought I'd point this out in case it would help with other potential issues.

It's unlikely but still possible that one of the speakers is internally wired backwards (it's happened before), so you may want to try reversing the polarity of ONE of the speakers (doesn't matter which) to see whether that improves the sound. Even better would be to use a special test tone to check whether the speakers are of the same polarity when actually playing.

You may also want to connect only one of the speakers at a time to verify that they both sound the same, just in case one of them happens to be defective.

Generally, you should turn off any unnecessary processing, especially any "DSP" modes that modify the sound. "Pure Direct" seems like a good option for your purposes, though, if it works as described.

These speakers are very "sensitive" (efficient) and should be relatively easy to drive (many speakers are not) at reasonable listening levels (i.e. neither deafening nor massively distorting), so unless your AVR is defective, I doubt that the amps are the culprit.

Headphones use a different and separate amp, and are very different speakers on top of that, so no.

That's understandable. Are there any other speakers you could try with this receiver to compare, perhaps smaller ones that you could borrow from somebody real quick?

Klipsch speakers in general are known to be quite dynamic, which is normally a good thing, but I have to wonder whether you're just not used to hearing certain things outside of headphones. This is probably not the problem, given the apparent severity of the issues you've described, but just for kicks you may want to try using some dynamic range compression or DRC (set it to high for experimentation); this option should be available for Dolby Digital soundtracks, if nothing else.

Try any or all of these suggestions, and report your results.
