Title: OB H/W Frame Wiring Info / Diagrams
Post by: Captainhemo on 10 Apr 2017, 06:34 pm
Hopefully this will come in handy for  folks wiring their H/W frame cabinets. Seems to be a need for a reference in regards to wiring the different layouts so figured I'd do a quick write up for each (maybe worth a sticky Danny ? )

In all these configurations, forward  woofers  are wired in phase, rearward woofers are wired out of phase.   
In all cases, driver coils are wired in parallel,  servo  coils are wired in series.

For dialing in your subs once you've got them wired, here is a handy drawing (http://www.audiocircle.com/index.php?topic=151754.msg1622832#new)  done by @THROWBACK that will help you keep a  record of your settings.


Here is the wiring color coding for the different servo amps:

A370PEQ
Red:+
Black: -
Large pair for driver coil, small pair  for servo coil

HX300
Black: +
Yellow: -
Due to the HX300's compact size, the wiring had to be small and flexible. IIf not careful, it can be difficult to differentiate between the driver / servo pairs so the  driver pair has been  wrapped with a black  heat shrink.

HX800
The HX800 has 2 seperate sets of driver/servo outputs.
Black: +
Yellow: -

Red: +
Black: -
For both sets, large wires to driver coils, small wires to servo coils.

Find  the example below that matches the layout you're building and follow  the  step by step instructions, I'll add some  basic diagrams at some point but  the  instructions should be easy to follow.

DUALS WITH  OPPOSED WOOFER (one forward, one  backward)

Driver Coils
Big red lead from  A370 to lower (backward) woofer - driver coil, then from there to upper (forward) woofer + driver coil.
Big black lead from amp to  lower (backward) woofer + driver coil, then from there to  upper (forward) woofer - driver coil.
Driver coil wiring done.

Servo Coils
Small red wire from amp to  lower  (backward) woofer - servo coil.
Run a wire from the lower (backward) woofer + servo coil  to the  upper (forward) woofer + servo coil
Finally, run the  small black wire from the amp to the upper (forward)  woofer - servo coil.
Servo coils  done.

DUALS WITH  BOTH WOOFERS FACING FORWARD

Driver Coils
Big red lead from  A370 to lower woofer + driver coil, then from there to upper woofer + driver coil.
Big black lead from amp to  lower  woofer - driver coil, then from there to  upper woofer - driver coil.
Driver coil wiring done.

Servo Coils
Small red wire from amp to  lower  woofer + servo coil
Run a wire from the lower woofer - servo coil  to the upper woofer + servo coil
Finally, run the  small black wire from the amp to the upper  woofer - servo coil.
Servo coils  done.

(http://www.audiocircle.com/image.php?id=161051)


TRIPLES WITH ONE WOOFER FACING BACKWARD

Driver Coils
Big red lead from  A370 to lower (forward) woofer ) +  driver coil , then from there to middle (backward) woofer - driver coil, then on to  upper (forward) woofer + driver coil.
Big black lead from amp to  lower  (forward) woofer - driver coil, then from there to  middle (backward) woofer ) + driver coil.  and finally to  upper (forward) woofer - driver coil.
Driver coil wiring done.

Servo Coils
Small red wire from amp to  lower (forward) woofer + servo coil.
Run a wire from the lower (forward0 woofer - servo coil  to the middle (backward) woofer - servo coil.
Run a wire from  middle (forward) woofer + servo coil to upper (forward) woofer + servo coil.
Finally, run the  small black wire from the amp to the upper  woofer - servo coil.
Servo coils  done.

(http://www.audiocircle.com/image.php?id=160804)


TRIPLES WITH ALL 3 WOOFER FACING FORWARDS

Driver Coils
Big red lead from  A370 to lower woofer  +  driver coil, then from there to middle woofer  + driver coil, then on to  upper woofer + driver coil.
Big black lead from amp to  lower  woofer  - driver coil, then from there to  middle woofer - driver coil.  and finally to  upper woofer - driver coil.
Driver coil wiring done.

Servo Coils
Small red wire from amp to  lower  woofer + servo coil
Run a wire from the lower woofer - servo coil  to the middle woofer + servo coil.
Run a wire from  middle woofer - servo coil to upper woofer  + servo coil.
Finally, run the  small black wire from the amp to the upper  woofer - servo coil.
Servo coils  done.

(http://www.audiocircle.com/image.php?id=161001)


Quds/6-Stacks
Use either  the  dual seups above  for bottom2 and top 2 woofers of  quads or,   the triple examples above for  bottom 3 and top  3 woofers of  6 stacks.. 
The bottom 2/3 woofers are powered by one A370PEQ or one of the HX800 modules, the top 2/3 woofers  are powered by another  A370PEQ or the  2nd module of the HX800.

Use the  4 pole connectors available from Danny to  connect the  amps to the  4 wires coming from the cabinets.

If you're going to sticky it, might as well correct the misspellings.  A simple spell check will easily find all of the ciol, coill, cooil, wooffer, fiannly, fainally, fromm and others.  Visual proofing will be necessary to catch a few others not caught by spell check, such as double words (coming coming), etc.

Very Very nice Jay, it is very kind of you to spend the time to do this for people. It can be very difficult to find the information in all of the threads. I bet a lot of people will be really happy to have access to this and I too think it should be a sticky.

I had to ask for someone to point me to where the diagram was because one wasn't included in the kit. Maybe Danny can use this to send out with all of his Servo Sub sales.

Thanks Jay :thumb:

Great info. Thanks for taking the time to post.

Recommend to also add a reference to the HX 300 amps which use black and yellow wire.
Title: Re: OB H/W Frame Wiring Info
Post by: mlundy57 on 15 Apr 2017, 01:23 am
If I remember correctly, on the HX300 the black is the hot wire (same as red on A370 amps).
Title: Re: OB H/W Frame Wiring Info
Post by: Captainhemo on 15 Apr 2017, 01:32 am
Thanks  Greg, I'll get the last  diagram done soon as well.
Mike / Odal3,  I'll have to double check  that... I do know on the hx800's  one set  of  leads is color coded one way,  the other is  reversed   (black is neg  then   on the other set (other mono)  it's different :scratch:

Ok,  last  wiring diagram  posted .
Also got the  wire color coding for the different amps from Brian (Rythmik) and added to the original post.

If you get these wired up incorrectly, either the servo coils or the driver coils, you will not get good results. If the driver coils are wrong you won't have much volume. If the servo coils are wrong the drivers can bottom out and/or the bass can be loose, flabby, or otherwise undesirable.

Thanks for this. I will definitely need it when I start assembling my triple OB sub.
It will be placed horizontally between the two front speakers, about half way between the listening position and the front wall...4ft each way. (it's literally the only place it can go).
Is there any benefit to going with 3 front facing woofers vs Front-Back-Front configuration?
Title: Re: OB H/W Frame Wiring Info / Diagrams
Post by: Captainhemo on 1 Apr 2020, 08:25 pm
Mike,  yeah,  I bumped it  as I get  asked  for help  with these  all the time and usually end  up referring  them  to  these schematics/step by step write ups  I did   way back.


Metfit77@g,    driver orientation   really  dosn't change the sound  quality... I've heard  arguments   for both options.    Probably  sending out about 98% of  kits  with all woofers facing forward.   Just  be sure to pay attention to the wiring differences

Hello, I am hoping someone can help me. I am hooking up a dual ob sub, but as opposed to the drawing, my top woofer is backward facing and the bottom is front facing. The driver coil section is fairly straightforward, but I'm confused as to how to wire the servo section.
Do I go servo amp (red) to red (bottom front facing), black (bottom) to red (top rear facing woofer), black to amp (black) ?
Or
Red (from amp) to Red (bottom), Black (bottom) to Black (top) , Red (top) to black from amp ?


Thanks in advance for your help.

It's not that bad. If you flip a woofer then flip the polarity on both coils.

First example on  first post of this   thread.   There is a  drawing of the terminals/wiring there as well.

"DUALS WITH  OPPOSED WOOFER (one forward, one  backward)

Driver Coils
Big red lead from  A370 to lower (backward) woofer - driver coil, then from there to upper (forward) woofer + driver coil.
Big black lead from amp to  lower (backward) woofer + driver coil, then from there to  upper (forward) woofer - driver coil.
Driver coil wiring done.

Servo Coils
Small red wire from amp to  lower  (backward) woofer - servo coil.
Run a wire from the lower (backward) woofer + servo coil  to the  upper (forward) woofer + servo coil
Finally, run the  small black wire from the amp to the upper (forward)  woofer - servo coil.
Servo coils  done.

hi all   getting my stuff together to put a set of the duel subs together . wondering what is the best wire to use for these subs ? and i assume the run from the plate amp should be as short as possible . and what gauge is the best for them also. thanks all hope to post some pics when i get started.    mark

The wires from the amps are already connected to the amps. Ideally you want to connect these to the speaker. When You order the kit(s) you can get Danny's 16ga hookup wire and 4 pole Neutrik connectors. The female connectors goe on the speakers and the male connectors go on the amp wires.
Title: Re: OB H/W Frame Wiring Info / Diagrams
Post by: Captainhemo on 10 Aug 2020, 05:30 pm
We never do it that way but it really doesn't matter.
Typically,  we  put the femaile connector  in the  hole that  most  customers  have us pre-drill in the  one end of the amp box(s).   When   we wire them,  we  usually  cut the  built in wire of the amp to  just reach the  female connector  ( actually  a bit longer  to allow  it to poke out of the hole  and wire up the  conector).  Then, we   leave a small run of the  chosen wire  out the rear of the sub ( it  tucks   away nice in the  bottom joingt of the no rez.  Then  just  add the male connector to the end of the pigtail.   

We too typically  use  Dannys   wire.... I think Tyson has had  good  results  using   a heavier  guage  siler  wire,  IIRC he even  replaced the  wiring   from the amp.....  still have  yet  to do this one.

I did use silver wire all the way back to the amp board.  But very high quality copper would work too.  The subs actually play up close to the midrange in my speakers so a generic “subwoofer cable” is not good enough IME.  Use as good a wire on the sub as you use on the main speakers.  Same with the subwoofer interconnects.  High quality, don’t skimp.

What do you recommend for subwoofer interconnects? Did you make your own?

Post by: Tyson on 10 Aug 2020, 10:56 pm
I do make my own.  The KLE silver RCA connectors with the VH Audio OCC in foamed Teflon wire will get you an excellent cable for not too much $$.

Easy Question for the Community but which I am flailing on, what size screws do you use to anchor in the woofers into the frame?  I have tried 3 different wood screws without success.  Am I missing something?  What is ideal size and length?  And is wood screw the answer or am I missing something?  A shopping list would be great for these build outs for the amateurs like myself!
Title: Re: OB H/W Frame Wiring Info / Diagrams
Post by: HAL on 27 Oct 2020, 09:27 pm
The wood screws usually come in the package with the SW12 style drivers.  Usually in a small plastic bag attached to the speaker.

None in the box?

Post by: Captainhemo on 7 Dec 2020, 07:41 pm
Well, the ones  that  come with the  woofers  are a nice  allen headed   wood screw, approx  3/4"  long (thread length).   Although not the most  common,  they seem to be a  #7 in size... you  might get  away with a #8  but  it may be too large to pass through the woofer frame.  Nice thing about the ones that  come with the woofers are that  the allen head  fits inside the recess  of the woofer flange, a typical wood screw, ispecially in the #8 size may not...
Might want to give  Danny a call and see if he happens to have  any    lying  around...

I'm planning to have the subs cabinets built by a local business here in uk. I'd like them to make boxes for the plate amps as well.

Does anyone knows the dimensions or perhaps has a drawing for those boxes? Is it fine to have them just as simple mdf boxes with some random holes for ventilation?

Thanks

Post by: Captainhemo on 22 Mar 2021, 11:41 pm
Amp cut out is  11 1/8  x 1/8  (A370PEQ/HX800).  The HX300's are smaller and I can't  recall of hand  what the   cutout zie is.

You  need about  5"  of  height   for clearence between the  top  and bottom  edge of    box frame
I liked the idea of some ventatlation although I am not  sure it is  required as I've seen    these amps in non vented enclosures...... if you  leave the bottom open  and add some "feet"   that  should  also do it.

Thank you

A note for the website:
The cutout info is also available under: https://www.gr-research.com/store/p39/A370PEQ.html
But this page is not linked from the "main" subwoofert kit page, so a bit hard to find.
