Volt 8 LX Build Starts Tonight! Build thread with pics...

Hi all, haven't received my 1099 towers yet so going to start building what I do have - a pair of Volt 8 LX's.

Here's what I've got:

Crossovers:
Digital multi meter
40W soldering iron
Rosen core/lead/flux solder
Nice new wire stripper
What wire do I need??

Cabs:
TiteBond III wood glue
Fast Cap Glue Bottle
Wood clamps
What kind of adhesive/insulation do i need?

Would greatly appreciate anyone to chime and let me know what I missed! I will be updating this thread along the way.

Thanks for any help!

18 gauge speaker wire. some zip ties. hot glue gun is helpful. mattress foam at walmart. spray adhesive. If u have a nail gun, installation is so much easier.

I've got 16g speaker wire is that OK?

will pickup zip ties, hot glue gun, mattress foam and spray adhesive. nail gun huh? i maybe could rent one...

Anybody have a picture of the LX 8 crossover? I found several of the non lx but some of the resistors are different this time around.

Ty, I had seen that but was on my phone and didn't realize I could pull the picture to the right.

Time to give this a shot.

it all helps thanks!

crossovers complete! Took a couple hours to complete but I'm a novice; it will be much quicker next time. although not very experienced soldering, I have done some in the past and will say I do prefer the 40W iron i am using this round as opposed to the 25W I've used previously. This iron had enough heat to flow the solder w/o having to touch it to the iron which made things cleaner. I hooked up the compression driver and woofer and both seem to be working perfectly.
Is there a scientific way I can confirm that my crossovers are functioning properly?

can't say i've EVER glued up a box before lol. I do not have a nail gun; just about 10 clamps.
Any suggestions b4 i tear into it?

In regards to finish, I'd like to use that textured black finish I've seen on a few threads. What is that called and do I need a primer?

Could you show us the bottom of your crossovers?

One thing I wanted to check for is to make sure you scraped off the reddish insulation on the big inductor leads.

Holes next to big inductor are for zip tie to hold it down.

Texture black finish is probably duratex. There are some "how to apply" videos on YouTube.

Did you solder to the tinned tips of the inductor, or did you cut the ends off? In the picture it's hard to tell on the large iron core inductor.

Did you read the 'Assembly Tips' page on the site?

Something like this for the foam samarai? http://www.walmart.com/ip/Simmons-Be...ingMethod=p13n

I will post a photo of the bottom sure thing Sean. Thanks for caring enough to help!

I hot glued the plastic 'feet' of the large inductor to the board. Is that OK?
Also, hot glued (small amount) the small inductor to the white resistors. Is that OK?

I'm supposed to scrape the red insulation off the leads? Thought I was to solder to the tinned ends?

Hi Erich. Yep I read it. I did solder to the tinned ends of the inductors but I also cut them off. The tinned ends were prob 1" long so I sort of split the dif, soldered to the tinned ends and then cut off excess lead under board. Is that OK? I assumed cutting off extra tinned ends would be OK as long as the soldered joint was to a tinned end, not the red insulation.

I'll try to get some closer pics up.

Ah, okay. Sounds like everything is okay. My leads were much longer than yours, so from the top it looked like you cut off a bunch and might have soldered to the insulated part.

I think general recommendation is hot glue everything and zip tie the big heavy stuff too to be safe.

OK, so the zip ties are more of a safe guard to keep the heavy stuff from moving right? In other words I didn't do any damage by gluing the inductors that way right? I may be able to clear the holes of glue and zip tie the inductors at this point.

Is there a way I can test my crossovers to make sure they are working properly? They sound like they are but there must be a more scientific way to verify them?

Keep the hot glue on plastic parts - zip ties go here


As for testing - someone else might be able to tell you some values to check against for that particular crossover.
What I ended up doing is just put everything together and see if it sounded right. I called that success =P

I have not yet gotten around to measuring with calibrated microphone, but that would also help uncover is something is wrong.

OK will do thx Sean. As I stated above the small inductors are hot glued to the white resistors. Is that acceptable?

Yea, that's what I did for my Volt 10 LX crossovers and seems to match the exemplar photo.
That inductor is light enough that I don't think zip tie matters.
(I would definitely defer to Erich on all this stuff by the way)

Here's a great video mtg90 recorded

I've got two inductor leads that I'm wondering about now only because I cannot see any tinned wire on top of the board. I'm 95% certain i did them correctly but because I can't see it I'm concerned.

Do them over? Would I hear sound through the speakers if they were incorrect?

I will not speak with authority on whether sound would come out if they were incorrect (I'm still quite new at this), but my quick look at the circuit board indicates that the circuit is not broken by the inductor having a connection problem (current still flows through the capacitor which is in parallel with the inductor) so sound would still come out.

I think you could melt the solder around the inductor leads and inspect them for any insulation problems.

Edit: Listen to mtg90 on crossover behavior over me

If the connection for the larger inductor is broken or bad you will not get any sound from the woofer, or it will be distorted/scratchy.

If the connections on the smaller inductor are bad it will be much harder to tell that something is wrong as that component works as a signal shaping component in conjunction with the resistors to flatten the response. Sound will still get through but the frequency response will not be correct.

To test use a multi meter in the resistance setting and measure across the resistor that is closer to the side of the board, you should read less then 1 ohm. If the connection to the inductor is broken at one of the ends it will read between 4-8 ohms depending on which version of volts you have.

I had two leads in question. I unsoldered them last night cleaned and inspected the end and believe both of them have been properly soldered to tinned leads. Regardless, I will use the multimeter as described above and check back thanks all

Box builds are progressing nicely. Headed to Walmart to see if I can find some bedding pad. Am I looking for egg crate shaped padding or just plain 1 inch flat? Also going to buy some spray adhesive there...

Still not sure how to mount the crossover just yet but I'll get there soon enough...
