Peavey SP1x and Peavey SP118x

cruzancowboy

Previously I posted questions..but didnt realize I had the Peavey SP1X and 118x speakers.

I need the crossover settings for these speakers. If possible I need it in simple terms.

Low---Low pass
Low---High Pass
Mid---Low Pass
Mid--High Pass
High---High pass

I have a Driverack PA set for sterio 3 way I have My Highs and mids for the right side coming from 1 crown CE1000 same for the left side from another crown CE1000
My lows are coming from a crown CE2000
I understand that my low end is kinda underpowered.
I am sooo close to having this system sounding great. I think the difference lies in the tunings for the crossover. I am yet to set that fully.

Features
This loudspeaker system delivers high
output, low distortion bass from a single
18\" BWX woofer mounted in a vented
enclosure. It is designed for portability and
includes handles, metal grille, reinforcing
corners, durable carpet finish and rubber
feet. A pole mount is included for
mounting of a high-pass enclosure.
Description
The SP 118X is an add-on subwoofer
designed to make it easy to add more low
end to the SP X Series or other full-range
speaker systems. Other uses include bass
guitar and drum monitoring.
The enclosure is constructed of 3/4\" high
density OSB and MDF, and covered with a
heavy-duty black carpet and reinforced
with polymer corners. A black metal grille
covers the front of the enclosure.
Recessed handles on either side provide
portability.
This low frequency enclosure is comprised
of an 18\" BWX Black Widow® woofer with
Kevlar® impregnated cone, mounted in a
vented enclosure. This design provides
strong bass extension and high power
handling to complement a full-range
sound system.

From your own post...

Recommended active crossover
frequency region and slope:
Low Frequency - High Frequency:
1600 Hz at 12 dB/octave, plus CD
horn EQ
Time offset:
Low Frequency:
Delay 0.67 ms
High Frequency:
0.00 ms

The subs are -10db at 50hz naturally. So something like...
50hz BW 18 to 90 - 100hz LR 24, then match (or very small gap) the 15\" mid's high pass to the above from Peavey. You'll have to find the amount of sub delay (probably max) yourself by playing. Don't forget that you'll need to attenuate the horn side of the amp or the high x-over gain, or the horns will cut your head off.
Keep us posted.

DRA

PS - An RTA mic will really help. Set a 1 stack out side and use the auto EQ and PEQs to set up system.

Gadget

And there is NO lowpass for the horns on the DRPA (Lowpass=the highest point you want a speaker to go).

G

cruzancowboy

Do I auto EQ with the RTA after I set the crossover?
OR does it matter?

Gadget

You read the \"Welcome\" \"READ ME FIRST BEFORE POSTING\" section as it will answer a majority of your questions..you know.. step 1...step 2...Really, we did that so you could get a really good jump before asking a bunch of questions that are covered there..

BTW the HF crossover point is 16 k or up and with your limited power I'd consider an even higher sub/mid xover maybe as high as 110/120hz.

I know...I am sorry I should know better than that.

I think you guys love \"knowing it all\"...lol

I really appreciate your help

cruzancowboy

OK...I feel like I am still missing something.

In the DRPA when setting the crossover I should have a setting first for the HIGH PASS for the Lows...Next the LOW PASS for the Lows.
I then have one for the HIGH PASS for the mids and LOW PASS for the mids. Finally I should have a setting for the HIGH PASS for the highs.
From what I have so far I am looking like this:

LOWS - HPF = 50Hz BW 18 ??db
LOWS - LPF = 110/120Hz LR24
MIDS - HPF = 1600Hz ?? 12db
MIDS - LPF = ??Hz ??
HIGHS- HPF = ??? Hz ?? ??db

Do you see now where I am getting stuck? Please excuse my ignorance
I am learning.

Dra

LOWS - HPF = 50Hz BW 18
LOWS - LPF = 110Hz LR 24
(18\" subs do 50 to 110)


MIDS - HPF = 110Hz LR 24
MIDS - LPF = 1600Hz LR 12 (or LR 24) try both
(15\" mids do 110 to 1600)


HIGHS- HPF = 1600Hz LR 12 (or LR 24) try both
HIGHS- LPF = NA
(2\" horns do 1600 to \"out\")

Clearer?

Go to the training module link above and download the 260 Driveware GUI software. It will make even clearer what you need to do.

Hi,
Been following... even did a post which...?hmmm... Nice work Dra... As for the Horns.. they are 1 \" throat and I wouldn't go ANY lower than 1600 hz...as the titanium diaphragms will prematurely self destruct... I recommend 1800-2000( the woofers go to well over 4000 hz so no worries..) for longevity sake. I have used the same diaphragms for over 8 years in the high output disco/karaoke format and have had no failures, as well as a number of monitors which must do vocal AND music duty for karaoke use in a high volume pro audio setup.

I also recommend you try both, but I believe you will see that less \"interaction\" will occure at crossover point with a 24 DB/octave filter, which will translate to better intelligibility at the crossover point .

Be well

cruzancowboy

Thanks so much! Thats what I needed.

Now..One more question has come up within my band....

I know that I can turn the GEQ off in the DRPA...I know by reading some of the other posts that I can use an outboard EQ to make quick adjustments on the fly. Would I connect this outboard EQ just before the DRPA in order to keep the \"FLOW\" of signal the same as the DRPA diagram shows?

Dra

You need to put it before. If you were to put it after you'd have to have 3 EQs. Not only is that expensive, it would be a nightmare to deal with x-over bleading.
Depending on HOW ON THE FLY you mean, consider leaving the DRPA EQ on, make the adjustment, copy to the DRPA EQ then take the outboard back to -0-. The DRPA EQ will be cleaner to the over all tone.

DRA

Gadget

Very good...well said. I would just like to add that as DRA has said, adding an analog GEQ into the mix tends to defeat the purpose of a single unit controlling the mix output, and will introduce unwanted sonic aspects that we try so hard to keep clean and simple. Once you have tuned your system properly, and set it for performance volume and flat response, you will find that quick adjustments on the fly will be largely eliminated. Pay attention to the links and see the one that has a room mode calculator and you can predict where problematic frequencies will occur. Be MOST aware of those that occur in the 200, 400, 500 hz regions, and those sub 150 hz as they will rear their ugly head the ;louder you get. Know also that the louder you get the closer the room will get to the point of no return, where feedback, modes and nulls will take over and you will be fighting for your sanity...The only recourse here is to live with the volume the room will allow.

I have another stupid question ! I want to try running the subs from a aux. send. I know I need a eq, and x over from my aux. send before going to the amp. Now the question, When I finish the rta - eq. wizard should I set the geq. flat, up to the x over point of the subs. ?
Or does it matter sense the sub out will be unpluged anyway ?

Dra

If you are doing an outdoor flattening session then the low data can be used (for the most part) and transferred to the aux output. But once you go inside all bets are off and you have to use your ear.

DRA

Gadget

No...don't do it! The aux fed sub method needs too much stuff your not likely to have... and the DRPA will make the system sound far better than using a analog xover and or a EQ...It also needs to be run POST fader as on a matrix out or better yet a VCA which I doubt you have ...

Also I missed that this is a 44xt... which is a 2\" exit and could easily be crossed @ 1400 hz...
