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.

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?

Tyson · « **Reply #33 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!

HAL · « **Reply #35 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?

morganc · « **Reply #36 on:** 27 Oct 2020, 10:04 pm »

No I do not have them as I got these Used.

Captainhemo · « **Reply #37 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

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.
