Why so many people blow tweeters and woofers.
Having been in audio for over 40 years, I have never blown a tweeter, had to change a woofer...fried a crossover....ever ! Yet we constantly see threads over at Polk on this. Are people that stupid they can't hear when the music starts to collapse.....hear that distortion ? Then blame the manufacturer for making a cheap product.
People think the volume dial is like a gas pedal, ment to be buried. The old "lets see what it can do" mentality. Which might work if you knew the limitations, if you knew what to listen for before backing off. Day in and day out, we see people post this shit. I would think, just a little....just a wee bit, that you'd seek to educate yourself somewhat before putting at risk a lot of good coin you just spent on speakers and gear.

Oh yeah man, some thieves are as sharp as a butter knife. By me....they break car windows for a pack of cigs. Break into homes and drop their wallets, steal purses and then use that persons CC at the same hair salon the victim used. Least we mention these idiots then post pics and brag on social media.

The education most consumers get when it comes to audio is NILL. I started out with a set of Polk Monitor 60's and was using a really cheap HTIAB Sony AVR. To make matters worse at first I didn't buy the right center, I was still using the really small one from Sony w/ a 3.5" woofer.
I found out quickly that was a bad idea. Then I joined AVSForum and learned about what I really needed AVR wise to make them work. If not for that site I may still be using my Sony AVR to drive a setup of Monitor's.
And I agree, most folks just crank up the volume and don't realize till something goes pop its not working. Mostly its due to the low price point of the Monitors which makes them more available to the average consumer. Add to it the fact amp sections in most AVR's people buy anemic at best, and you have blown tweeters...
Now when it comes to car audio, well I had 2 sets of Polk db6501's. Out of that 2 pair I now have 4 working tweeters, 2 working mids, 2 working xovers. Mostly because I taxed them with TOO much wattage and blew the crossovers and mids. That and the speakers deal with extreme heat and cold given I am in Indiana and winters are COLD and summers are HOT.

I think alcohol is involved more often than not when speakers, crossovers, or amplifiers are blown. Impaired judgement.

Quick question, was listening to some music earlier "CD" on a parasound 2250, pre2100, sony cd player, SDA SRS's, between songs, I increased the volume a tad and heard some static noise coming from the left speaker as I increased the volume "the next song had not started yet". Checked all connections, seem ok..any thoughts? TKS

You mean in that dead space between songs ? That can be a variety of things. Certain volume dials themselves introduce noise, cables, your outlet, line noise in the circuit. Sometimes it can be the electronics within the speaker itself. Usually it's a line noise, dirty power. Which is why a lot of us use power conditioners/regenerators. At higher volumes, it's certainly heard. I use a PS Audio power conditioner, the Quintet....quiet as a church mouse.

Yes, the dead space between songs. Funny thing is, just noticed it today, only thing unusual was the storms we had here a few days ago, before they got here I unplugged everything as we always loose power during storms. THANKS for the information. Will look up the Quintet thing this evening. Once again THANKS a bunch!!!

PS Audio no longer makes the quintet, you may be able to find them used on Audiogon. I bought mine as a store demo from a HI-FI shop in Florida. Came looking brand fucking new in the original box too. Of course they have other models too, but if you want to save a few bucks, look for store demos.

The second pair of SDA's I bought had the tweets replaced under warranty. They had been powered by a receiver. On the speaker manual was a written Polk suggested amp recommendation, an Adcom 555. The guy bought two and never blew a tweeter again.

i never turn my yammy over -17, usually stays about -22, for movies, music depends on my mood but -32 to -20, and watching tv or anime it stays around -45 to -28. pc use it stays around -55 until i need it turned up. speaker levels on the avr set around 70 percent, volume on sub set around 90 percent, sub level on the avr around 55 percent, dont hear any static or much in-between noise, all is run through monster surge protectors and i use my remote intead of the knobs when possible. i know that i may run it a bit high at times, but they never get pushed hard for long.

As a general rule, you shouldn't turn your volume up past 50%. If you have to turn it up higher than that, it means you aren't using a powerful enough amp. I think that applies to powered subs as well, but I'll let others chime in on that. I keep mine set at about 35%-40%. Where on the dial is completely dependent on the gain & input/output impedance of the preamp/amp sections. MANY companies use a non-linear volume control that gives almost all the gain in the first 120 degrees of arc...this gives the impression the amp is "powerful"...it's simply a marketing stunt.

Correct me if I'm wrong Dan, but I believe you keep the sub's volume so high because you listen at lower levels and still want that lower bass to be prominent. Correct ?

Your correct, but you can turn it up SOME to your liking. I would think anything around 60-70 percent is pushing it depending on the volume you listen at. Thing is if you leave the volume dial at almost full on the sub and then turn the volume up on the AVR, your going to over drive that sub and cause some damage. Dan, listens at way lower volumes so that's not an issue for him.
Also check where the calibration set the subwoofer levels, it may be too low as most auto calibrations have a knack to do. Never take the auto calibration as gospel, always check the settings for all speakers and tweak them if you think it sounds better.

ok turned it down to 65-70 LOL.....At your listening levels, not really a problem. No volume dial should be at 90%, subwoofers included. That high introduces distortion and line noise into the signal. When playing a movie at higher volumes and dynamic sounds happen, you won't have time to run over and turn it down either, hence over driving the sub. The 50% mark is a rule of thumb to blend in without over driving subwoofers, theirs some room for adjustment either way but not 90%. The 50% mark is also a good starting point for calibration software which will adjust itself accordingly to do it's job at most reasonable listening levels. Subwoofers are probably the hardest part of HT to get right. Everybody has different tastes but the key is to making sure you buy the right size subwoofer for your room. Too many times I see people with a small sub cranking up the volume on a smallish subwoofer to fill a larger room then wondering why it's bottoming out or the lower bass sounds weird. Then when they get it right for HT, they can barely hear it on music. That's why finding that middle ground is important. Music doesn't have those low bass notes a dynamic movie sound track does.....most the time anyway. Finding that right combination of crossover points and volume dial may take more tinkering manually than what an auto calibration software does. Don't be afraid to tinker, that's all I'm saying.

Agree, subs can be a PITA. I have three subs in my Living Room//Home Theater. All were calibrated to 75db separately, and then I let the Pioneer's auto calibration do it's thing. I then went into the saved settings and fine tuned them with my Rat Shack Digital SPL Meter. None are set above 50%
