I have 2 Peavey PT PA 112 Speaker enclosures w/16 ohm speakers, good for 100 watts each, The enclosures are good,
The peavey power mixer is a 8600D version, 2 banks of 600 watts each at 4 ohm outputs.There running in series off 1 bank
? #1: is it foolish to upgrade to a better speaker with 8 ohms and use the same enclosures?
I`m trying to get better sound quality and volume at a cheaper price.
If its not to stupid of an idea, can anyone please tell me what speaker in 12" will help this situation.
I see new replacement speakers for sale on here all the time,
I would love to play my steel through This PA system especially at my home,
The 16 ohm speakers just aint doin it...
Best Regards , Craig

If you are in fact running "in series" you have created a 32-ohm load, limiting your amp to <75 watts into BOTH speakers. However I suspect that this is not the case as it would require a special wiring harness to achieve such a hookup.

Not necessarily foolish but "better sound quality" is a function of the speaker and enclosure working together and with a differnt speaker the frequency response and speaker loading will not be the same. Better to sell what you don't want and get something designed for what you DO want.

Your mixer's amp is far too powerful for these speakers. If they are in fact hooked up in parallel, which is most likely, and your amp pushes 600 watts into 4 ohms it will then push >300 watts into 8 ohms and >150watts into 16, either way this is considerably higher than the rated 100w max power for those speakers. If that is not loud enough for use in your home you may want to consider a smaller home...  |

Hi Dave , I like your report smarty pants...LOL
It must be parralell and not series off 1 bank,My Bad
when I use both banks the master has to be up so high on each volume pot that the clarity of 16 ohm is giving me a white noise with less volume,
Using 1 bank in PARALLELL seems to cut some of the white noise out (still there) but give a little more volume,
the steel sounds terrible through it, although mics (voice) sounds great, does that make any sense , Thanks for posting

Thanks Dave, I didnt realize the enclosure has to be matched to the speaker so critically to create a better sound, thanks

Glad you appreciate a wee bit of dry humor, Craig...if all is in proper working order the two amps powering individual cabs should be as loud or louder than one side driving both in parallel and either way you should be able to blow yourself out of the room.
If you are getting "white" noise at power something else is at issue, an impedance mismatch at the front end most likely. How are you hooking up the steel to this PA head? |

Dave , my wiring is psg-vp-delay-reverb-any channel on mixer, they all sound the same
Although a regular elec guitar sounds decent straight in, voice mics sound good HMMM ?
Both steels sound crappy (maybe its my playing) I kinda walked into that one...

Are your delay and 'verb guitar stomp-boxes or rack mount units?
The line inputs of your mixer should sound great with rack mount (line level) units plugged into them, guitar stompboxes will not have the appropriate gain (too low) or impedance (too high) and will yield noise and/or low signal level.
The fix if you are using guitar gear would be to try plugging the reverb output into a 1/4" DI input and taking the XLR mic level output from the DI into a mic input on the mixer. |

Hi Dave , I will try that DI input and let you know how it worked, This mystery is over and out !
Thank You Dave

Dave You are the MAN!  I borrowed a passive DI, WOW did it make a difference, the speakers lite up like they should,
The volume knobs now sit at 10 o clock on channel and main knobs, (instead of 3 o clock) still running it paralel and it now blows my hair back and the white noise is gone, Now that I have the volume,The sound is good, but It needs to be cleaned up a little, meaning EQ`d. When I use the peavey effects on power head it clips, So I turned that part to off.
Ive looked into an active LR Baggs par acoustic DI,or Can you suggest one of these for getting out to an open mic stage setup and for home use? OR am I on the wrong track again? This seems to be happening to me lately 
Dave I cant tell you how thankful I am... Other than, Thank You
Best Regards
Craig

Glad it worked out, Craig 
The Baggs DI is a great unit if you are going to use it for connecting an acoustic guitar or other such instrument directly, but for matching your steel gear as discussed here to a PA head save your money, an inexpensive passive (transformer) DI is all you need, don't spend more than $40 on it, save your extra cash for future purchase of a decent combo amp.
Bear in mind that if you are going out to play "open mic" events with your steel that the results from plugging into a house PA will not be the same at all as what you can get using your PA head for a personal amplifier. Decent results CAN be achieved but doing so requires that you have your own monitor mix and speaker to hear yourself properly, and maintaining a proper mix with the other instruments and voices requires know-how and constant attention.
For casual jams and the like a small combo is still the ticket, but if you get there early you should still be able to use your own PA head and speaker cab(s) as a substitute amp. |

Man I feel like I pooped in my pants again, 
I`m sure glad you were here to clear up my mess  Thanks again
& For all those that have sound problems , You need to talk to this guy Dave,
He knows his @#!t , he`ll set you straight the old fashion way with honesty 
He sure got me out of dark whole, that I was diggin !
best regards
Craig
