Problem

[Timmy245]

hey guys
this morning i was playing music and pushed it fairly loudly when i heard a "pop" noise from one of the speakers (klipsch f-1s for fronts klipsch c-1 for centre, and klipsch s-1s fro surrounds along with a klispch sub 10") receiver is denon avr-789 once i heard this noise i straight away backed off the volume the speakers all still sound fine but im still worried that there may have been damage caused is there any way to find out wether damage has occured

also when i have nothing playing but the amp is on theres loud static coming from all speakers and it is really quite noticable, is this normal??

one other question the sub when i am watching movies tends to rattle when it gets to a really bassy part im unsure wether this is something wrong with the woofer or just the build quality of the box.

please help these problems are getting quite frustrating

thanks in advance
TiM

mmm

You should have no static from the speakers, i would check all connections to make sure a stray wire on the speaker or amp isn't causing a short. was the static problem occuring before the speaker popping incident?? you may have bottomed out a speaker, causing the popping noise. If so, hopefully it did not do any damage.

hey cerwinmad
thanks for the advice and yes the static ws happening before the popping noise. as i turn up the amp the static gets louder but only when something is not playing
thanks again

You blew your amp. Specifically, you have a bad component in the preamp.

The rattling could be the sub's driver or the box. When you get your amp fixed you can inject a sine wave into the amp and check where the noise is coming from. There are several free programs that turn your PC into a signal generator.

I second that.

I don't think your sub problem is related directly to your receiver. You are probably pushing the sub to the limits that it's not designed for. The possibilities are: poorly build leaky enclosure, underpowered distorting amp and finally, miscalculated driver box combination allowing too much woofer movement for it's x-mas. Neither one can be resolved by an average consumer. You may need a sub with Higher SPL and lower distortion capabilities. Try to run some 20-2000hz frequency sweeps that you can download free and burn on CD.

hey thanks for the replies
the thing with the amp is ever since i have had it if i had it at loud volumes when nothing was playing there was static i assumed this was just ormal static because of the high volume
has anyone else had this problem and if so did your warranty cover it?

 

[adwilk]

A receiver set to loud volume with nothing playing through it will produce some white noise in the speakers. Thats normal. However, you shouldnt have your receiver up that loud if you're not playing anything... there's just no reason to.

Nothing personal, but your sub problem is a product of a poor sub. Its an entry level device not designed for high performance. Turn it down.

What source component were you using when listening to music? Do you know which speaker popped or did they all pop...?

 

[fredk]

Try playing one speaker at a time at low volumes to see if they are all OK or if you can identify one that might have a problem.

The pop could also have been the sub bottoming out when overdriven.

How big a room are you in and how close are you to the speakers when listening?

IMO, you need more power. Specifically, high headroom amplification. That receiver isn't the kind that was made to crank at high volumes. Nice receiver but it would be better if the speakers were more sensitive.

If you hear hiss all the time, your amp does have a problem.

 

[Timmy245]

hey and thanks for the advice

firstly adwilk the receivers minimum is -80db its max is +12db the static kicks in at -50db (i need to have my head next to the tweeter in oreder to hear it) but when it gets to about -30db you can clearly hear it from about 2m away

On the sub i agree with you that it is an entry level sub and i am already planning to get a new sub of high quality opinions are welcome.

i was listening through the ps3 and i had it around -10db im not even sure it was the speaker maybe it was the sub its now a day later though and i havent heard anything wrong with the speakers or the sub (apart from the static which has been there since day one)

fredk- i have played one speaker at a time but cant identify any problem my room is only 4m by 4m so not big, when listening im within 2 and a half metres.

Highfigh - i have been looking at uprgrading the receiver to something like a denon 4310 in a few month but in the meantime i would like to have all these other problems solved. and arent klipsch speakers extremely sensitive?

Thanks for the advice

one more thing hifi there is only static noise when nothing is playing as soon as i play a song the static immediately disappears ready for the song to play.

Hey, Timmy.. Like I said, the slight white noise is just fine... the Architecture of solid state amplifiers produce that noise. The "T" circuitry is the only solid state amp I know of that produces no white noise whatsoever, no matter what the volume is...

Yes, the Klipsch speakers are plenty efficient, however, they can produce some serious impedance dips and CAN be pretty taxing on an amplifier. It doesnt happen often though that you would be listening loud enough to clip the amp. If you do however, the horns are so revealing that they could have "played" the "POP" if the power side of the amp crossed into the signal side for a brief moment.

Sounds like everything is fine... If you're listening that loud, you might need more headroom by way of a more powerful amp, but you're probably using such minimal wattage when listening normally. Its also very possible that something was wrong with the source signal that caused a pop.

I would be careful... I'd slowly turn it up. If you are underpowering the Klipsch towers, you can blow the tweeter in the Synergy line.. I've never seen the tweeter in a Reference line blow, but I've seen it plenty in Klipsch's price point offerings...

 

[Timmy245]

Thanks very much for the advice adwilk
i have gone back to the store i bought it from and told them about the static and that i thought perhaps there was a little too much and there getting onto denon to try and resolve the problem so thanks again for all the advide

 

[adwilk]

Cool, good luck..

 

[Timmy245]

Thanks
i have been looking for subs to upgrade to and i think i might go with the svs pb13 ultra only bad thing is with living in aus its quite expensive, do you know of much better than the pb 13 ultra in the same price range?
cheers

Its gonna be hard to buy much better than the ultra at the price... You could certainly build a sub though...

I dunno whats available in your area though. You might start a thread in the DIY section..

Just ask about building a sub there....

 

[fredk]

If you are handy, building your own sub will give you more bang for your buck. There are some very good drivers out there and a very large DIY community for support.
