especially tweeters...what cud damage or say, kill it?...is setting up on a "series" connection damages it?

....when the amplified signal you feed to your speakers are beyond the wattage rating of the speaker... drum n bass mixes... wrong EQ.

I was thinking that mostly wrong wiring or when your hot and cold signal having contact inside the connector did burn your speakers ?

can u trust yr ears on this?..i mean,,what if ur not liking what yr hearing?..so u need to adjust yr eq..specially for the drums..what if sa pandinig mo...di nmn over yung eq..and its not peaking naman or clipping sa mixing board?..so how will u know?

we just burned one tweeter of our peavey pr15 400 watts..and i was thinkin what went wrong..our soundman always sets it up on a series connection to the amp..is that ok?..is it not the culprit?

3650guy · « **Reply #5 on:** April 16, 2008, 09:06:23 PM »

its really hard to say what happened to those tweeters. the spec sheet for your model mentions that it has "tweeter protection" so what could have happened? dun sa links mentioned ni sir tarkuz refers to "underpowering" a speaker...

best thing to do is to have it checked by a qualified person. also the other speaker if this is a pair of identical speakers.

ay..gumana na pala..its helpful..tnx a lot sir tarks...anyway...ganto kc..mejo nag away kmi ng soundman nmin dito...dhil nasirang tweeter...ng peavey pr15...ako kc music director sa church nmin...and i was tweaking the acoustic guitar channel...tpos pinaalis nya ko..dun n lng daw kmi sa stage wer we belong...nairita ko..tpos npunta kmi sa kung sinu nakakasira ng tweeter...sa inis ko nsbi ko n lng na "nasisira yan kasi lagi nyo sini-series!"...e kc lagi nmn tlgang natotoast e..tpos etong bagong PR15..natoast n nmn yung isa...and ever since naman sya magtimpla ng sound..palpak...wala syang sense of musical soundstaging...importante sa kanya maganda bumayo..ang babaw..feeling kc mgling na sya porkit me alam ng konti sa electronics and me mobile disco business...kaya gusto ko ako nagtitimpla ng sound namin bago ako pumanik sa stage..

anyway...parang pinalalabas nya na yung pag tweak ko ang nakakasira daw sa tweeter...e i know nmn whats use and abuse...madidinig m naman e...yun..nasigawan ko tuloy na "di ko kayo kelangan dito!"...kc parang minamaliit na ko e...

so im trying to prove my point lng na di kami ang nakakasira...and widen my knowledge tunkol dito...

anyway..back to yr post...this is our rig-

2 400 watts peavey pr15
2 350 watts soundtech cx10(ata)us made pa..not korea
2 1000 watts spl subs

1 1500 watts bts power amp
1 250 watts(ata) yamaha p2500 power amp
1 150 watts(ata) yamaha p1500 power amp

1 deton stereo crossover
1 dbx comp/gate
1 behringer xover din ata(composser xl ata i think)
m-audio dual eqs
2 soundtech eqs

...para lang me idea kayo...

tnx for the input...

Tarkuz Toccata · « **Reply #8 on:** April 17, 2008, 05:28:52 PM »

It sounds like you need a Sound Contractor or Consultant to look at your PA system and determine why your tweeters got toasted. I am guessing that a complete system redesign may be in order.

What are the dimensions of the church (venue): length, width & height? Don't worry if these are not precise, we can refine later if necessary.

If you have a peaked roof, what are the heights: from floor to peak of roof & from floor to top of sidewall?

What is the seating capacity of the church? (How many members attend on a regular basis?)

If you have acoustical information, it is a great help.

DarkHorse · « **Reply #9 on:** April 17, 2008, 05:58:36 PM »

tnx sir tarks...

as of now kasi ginagawa pa yung actual place of worship namin so itong lugar namin mejo abnormal in size, shape and acoustics dahil temporary lang so ill try to take sum pics and post it para mkita mo...

anyway we are a 700-800 congregation church if it helps...

and im talking to an engineer from LOTA AUDIO...dito ko rin sya nakita sa phmusic para sa redesigning..wait ko pa mapprove and wait ko din yung actual place namin bago ko sya ikontract cguro kasi useless din kung lilipat din kmi pg nagawa na yung place ryt?..sayang lang bayad..mahal pa naman..hehe...

tnx uli sir..u guys are as always..of great help...godbless..

pizarro84 · « **Reply #15 on:** April 25, 2008, 09:51:16 AM »

possible po kaya na may laging clipping na channel sa amp kaya nasira yung tweeter? parang duda po pati ako sa setting ng EQ, parang may artistic quality eh

DarkHorse · « **Reply #16 on:** April 25, 2008, 09:54:20 AM »

@sir tarks

yes sir..yung bts..i think its a 1200 watt amp pala..600 watts per channel...BTS SPX1200...our soundman seriesed the connection btw...dont exactly know how it works...

Power rating of BTW SPX1200 is 600 watts per channel into how many ohms, 8 or 4 or 2? What speakers are connected to the power amp? I am confused about the "series connection". Please clarify.

DarkHorse · « **Reply #18 on:** April 25, 2008, 04:15:18 PM »

confused din ako series e...basta i know mas malakas ang output pag naka series...and sa malamang about the ohms..its on 8...

sa pagkakaalam ko po mas malakas ang output pag parallel kesa series speakers pero di dapat bababa sa 2ohms depende pa rin sa power rating ng amp.

alkemi · « **Reply #21 on:** April 25, 2008, 08:46:02 PM »

sa tweeter,, isang matinding feedback gawa ng feedback sa signal sa board or sa mic na halos mabingi ka sa taas ng frequency ng feedback sound, chak sira ang tweeter ng speaker.

from experience, dalawa na narinig kong naputukan ng tweeter..tweeter ng ns10 and tweeter ng alesis monitor one

pero teka, reading the thread, muka live application pala ... yung series series nayan ang medyo diskumpayado ako.. yung wattage distribution ang problema din dyan..napunta tuloy sa tweeter ang wattage na hindi dapat.

When loudspeakers are wired in series, the impedance or opposition to current flow increases and less power is developed. An 8 ohm speaker and an 8 ohm speaker wired in series would result in 16 ohms of resistance to current flow.

When loudspeakers are wired in parallel, the opposition to current flow from the amplifier is decreased and more power is produced. Two 8 ohm speakers in parallel become 4 ohms.

Loudspeakers that PRODUCE music (guitar amplifier loudspeakers) are different from loudspeakers that REPRODUCE music (sound reinforcement loudspeakers). It is acceptable to wire guitar amp speakers in series and parallel configurations. However, sound reinforcement loudspeakers should not be wired in series, especially if the loudspeakers are intended to maintain a tight response on the low end for bass guitar or kick drum. In a woofer, series wiring-connected loudspeakers destroy the power amp's damping factor.

Quote from: Marty McCann, Peavey Electronics Corp.

Damping factor is defined as how well the power amp controls the load or the motion of the loudspeaker. When a high damping factor exists, the speaker is well-controlled (i.e. it moves as soon as the power amp asks it to and the speaker stops as quickly as it is told to). When the damping factor is lowered, the speaker doesn't respond as quickly and accurately to the demands of the power amp. Reduced damping factor results in muddy and undefined bass response.

Tarkuz, don't PAs come with passive crossover networks?

pizarro84 · « **Reply #24 on:** April 27, 2008, 06:31:14 PM »

sseing the pictures sir darkhorse, parang may artistic quality po yung setting ng EQ ng mains at monitors

Based sa link na binigay ni sir tarkuz, pili kong culprit sa setup nyo sir wrong EQ settings (parang sobrang daming naka dip na ibang frequencies po kasi at mukhang 10khz po yung emphasized and yung mga lower bass frequencies so sobrang layo ng gain nila nung ibang naka sagad sa baba. yung churchmate po namin na sound engineer may ganyang peavey din pero di ko pa po siya nakitaan ng ganyang EQ settings with artistic quality sa mga setup nya, and dapat po separate EQ's yung peavey at soundtech kasi makaiba ang tone sigurado nung speakers na yun) at malamang pati clipping signals (hunch lang po

).

Buti na lang pala ako din ang sound engineer kuno sa church namin and at the same time in charge sa PNW kaya walang conflict

yung EQ po kasi namin pinapa-RTA namin sa churchmate namin na audio engineer talaga (mentor ko at madalas humahawak ng PA pag tumutugtog na kami), pero recently nasira yung setting kasi ginalaw ng mga bata habang nagja-jam kami after the service

Sa pagkakaalam ko po sir kit dapat lahat ng ok na brand na PA speakers may passive crossover, pero yung iba pwede i-bypass pag gagawing bi o tri-amp
