Re: Treble.

Well i should state that the pc sub is THX certified....not that it means much but at least i know theres some type of quality control. but ya it sounds alright to me.

Also i know frequencies are not exact. so i take the numbers with a grain of salt. but even if its 15Hz off its still not bad. But after updating all the speakers and receiver i can't help but think of an old idea. That things are only as good as the weakest link. and in this case it would be my sub. But can a mediocre sub bring a system down that much...i don't know.

and ive been looking at subs. from the polk line since it would match the speakers i have. they have one that seems good for 250...well seems good to me. Also been looking at Velodyne line of subs.

Velodyne subs are REALLY good. The 12" goes on sale every once in a while at futureshop.ca for almost half price. Next time it does I'm buying. A friend of mine purchased one and he was amazed at the sound it uts out.

I haven't heard any Polk subs but I'm sure they have some good ones. Also Paradigm makes some really good subs. Depends on your space and budget.

Well I have been listening with lowered treble and my center still has that distorted sound. I put my ear beside the tweeter and it doesn't sound like a crackle but more like a vibration when reproducing higher pitched voices. Like in Rambo 4 at the beginning when the guy tells him off for bringing to many cobras.
My center can handle up to 150 watts and has a range up to 50000 khz (I know my cats get to hear those high frequencies ) so I am disappointed that it is doing this . Anyways has anyone heard the tweeters off of Parts Express.com? Like the Pyle Pro? Are they any good? The price seems to be good in case I need to replace the tweeter.
I was looking at this one!

Careful there Ironbull...your speaker's driver elements were matched to the characteristics of the cross-over, the cabinet and the other drivers...unless you can get a new, identical driver, you may be less than happy with the results of any swapping you are planning on doing.

BTW - wattage ratings are guidelines only...I can drive a 50 watt driver with 500 watts of clean power and be fine...yet if I took the same 50 watt driver and hit it with 50 watts of dirty power - bye bye driver.

But, I have noticed that there is a lot of over modulation on certain titles lately...sorry, but I cannot remember which ones...I think one was Shoot 'Em Up...just a level of fuzziness in the sound. Rock solid on older titles though...

Your setup may be fine...you may have just hit a cluster of bad software with poor sound tracks lately...

This is my center channel.

Thats what I was kind of thinking about the sound tracks themselves. You know when you watch deleted scenes and the sound is not cleaned up and sounds too um crisp or over bright? That is what I get on my center from time to time. Maybe your right and it could be over modulation like you said. HHMMMMM!
Thanks Though!

Ironbull, you can try and replace the tweeter, but IMHO, I'd go and buy another center channel speaker before attempting to fix it. Be a lot cheaper that trying to fix in the long run...you may save yourself some grey hair in the process

Ironbull,

I agree with r-u-serious. One of the biggest problems with simply replacing any driver in a multi-driver system is that manufacturers match the various drivers to be compatible with one another, and one of the biggest compatibility issues is efficiency. Different drivers, even of the same shape and size, will often play louder or softer for the same power input. You could wind up replacing your tweeter with one that plays louder or softer than the midrange driver in the same unit. Then the speaker would be too bright or too dull.

If you really want to keep the center channel speaker you have, contact the manufacturer and replace the tweeter with something they recommend. Otherwise, I'd say buy a whole new speaker.

That makes sense. I think I will just replace the speaker in the event it does blow the tweeter but the problem is only intermittent. I am just exploring some options. But I think I need to troubleshoot the vibration/crackle?!?! some more.
On that note does anyone know of some soundtracks with some bad over modulation that I could compare to?
Thanks Again.
If the tweeter does someday go it will be a lot easier to convince my Wife that I NEED A NEW ONE

Ironbull,

If you open up the enclosure (while your wife is gone) and stick a small pinhole through the tweeter material, you will get all the evidence your wife will need for you to buy a new unit.
