Bravo Kit is shipping. I'm new to the site and didn't see this topic (can't search yet) so thought I would throw it up. I'm a newbie here and out of the DIY for many years. Looking for a good picture of a finished Bravo Crossover with upgraded Sonicaps and Miflex Copper Bypass Caps. Plan "A" is to try and build my cabinets from scratch.

Neo,
I tried to private message you but your brand new member status doesn't let you receive messages yet. I dont have a clean picture that will help you but I can provide you with a scale layout drawing that shows the components and wire connections in a correct layout. I have provided the same assist to others and a layout drawing showing actual components and connections is very easy to follow. Even better than a photo.

Danny has just recently finished building a pair of Bravos and shot several videos for the assembly process, so those videos should be launching soon.

Thanks looking forward to the videos.

Caution to all the newbies', Respect your parts. Resisters can break, was standing at my desk and dropped this resistor onto my desk, landed flat and crack! I'll be more careful now. GR-Research was responsive and very nice about this replacement part. Good to work with a company that picks up the phone after the sale!

Nice one!
I broke a lead off a cap :duh:
You get to see the inside of the part so that's cool.

That is great news. Looking forward to watching the video.

Is it safe to use this Soldering "Torch"? Is it to hard to control the temperature that I would risk damaging Crossover parts? Dug this Torch Soldering gun out of my storage.
Anyone have experience / opinion on this?

The key is going to be to heat up and get off quick enough so you don't telegraph heat where you don't want it. I have a similar torch/ iron, but never got the chance to use it for crossovers or the like. It died and Master Appliance was less than good with their support.
I'd experiment a little first.

Cross Over Question. Are the Sonicap Capacitors directional? How critical is it to have a specific input and specific output side to this capacitor?
Here is a picture of my Cross-Over before Soldering. The 9 UF Sonicap may be situated backwards.
I started to unwind the wires and I was afraid they were going to break so I stopped and posted my question here.
Holding off on soldering until I get an answer here.
-
None of our crossover components are directional.
So you're good.
It's recommended to keep the input to the left of ghe text. But it wont hurt to have it backwards.

X-Overs mostly done.
Time to plan some worthy Speaker Cabinets.

How critical is the overall cabinet dimension? If I shrink the overall dimensions down by 1/4 inch would that adversely affect the sound?
I am thinking I would like to put a hard wood end grain pattern on the outside of the cabinet, like a 3D cutting board but cut to 1/4 inch instead and applied to the outside of the MDF cabinet. If I use 3/4 inch MDF and then add 1/4 hardwood that would be a pretty thick and larger cabinet. To keep the overall outside dimensions the same as the drawing, which I would like to do, space is a factor and 1 inch panels seems excessive, I'm thinking I have two options, 1) use 1/2 MDF for cabinet then apply the 1/4 Hardwood 2) use 3/4 MDF, reduce overall MDF dimensions by 1/4 inch, then apply 1/4 hard wood.
Any more wood workers have any suggestions?

I'd keep the measurements the same and just add a layer of the hardwood plus increase the radius on all corners, or use 1/2" MDF and 1/4" hardwood.

When you say, "increase the radius on all corners" could you clarify that for me? Is that only if I choose to have 1" panels (3/4" MDF + 1/4 Hardwood)? Do you mean to router along all outside joint edges down or the inside baffle holes, both?
Please clarify, just learning the verbiage here.
If I choose to use 1/2" MDF and 1/4" end grain hardwood for 3/4" panels would I still need to "increase the Radius"?
I will keep internal dimensions as drawn in the plan.

If you go with 3/4" + 1/4" thick panels, use a larger a roundover/radius on the left & right edges. The other edges aren't as important, but the top will help a little bit.
If you use 1/2" + 1/4" panels, you can use the standard recommended roundover/radius.

Can anyone confirm the inside Dimensions of the Bravo?
Looks like 10 1/2" High X 6" Wide X 10" deep.

Cabinet plans are on the site.

Making progress, intermittent and slow but having fun and moving forward. Learning about woodworking and how to use new tools, All good. Using a Walnut, Hard Maple and Red Oak pattern applied to MDF. I'm still hopeful I can pull off creating an acceptable looking and sounding cabinet.

Those are going to be stunning!

I love how the pattern plays with the eye creating a 3-D illusion!

morganc, borism, thanks for the encouragement.

Plan A Three D pattern was a failed effort. Gluing 1/4 inch cut hard wood end grain onto 1/2 inch MDF turns out is a real bad idea. The boards warped like lasagna noodles! All those clamps could not keep it all flat. A lot of work went into the dumpster. Should have just made a bunch of 3D Hard Wood end grain and cut them at 3/4 inch. A big time killer but Live and learn.
Plan B - 3/4 MDF with Cherry veneer. It is coming along, 2nd coat of oil based Satin clear varnish. X-overs soldered and ready for install. No-Rez applied. Can't wait to finish these so I can hear them.

Why do pictures upload sideways?
Any way to edit that?
-
You need to edit them (i.e. crop them slightly) on your phone before uploading them. Or adding them directly to your gallery before sharing them here.
-
I'll try posing pictures again that are orientated correctly. These have been rotated in Gallery.

Need Tweeter gaskets. Tweeters sit slightly low.
Any suggestions on where to buy gaskets to correct how my tweeter sits in the cabinet?
Will this tweeter sitting a little low in the flange be noticeable if corrected?

Received a suggested solution for my gasket question from a Butch. Thanks for the idea.
