Has anyone on Oppo built a set of speakers, built these speakers above (Speedsters) or know of any advice when building speakers?

Premade cabinets or making your own from scratch? All the other parts are easy but I suck at wood working so I would get premade hah

Those look nice. I’m thinking about upgrading. I bought all mine at TSC years ago. I’ve been looking at clearwave kits.

I built a pair of Overnight Sensations at the end of 2014. I used a pre-cut kit from Parts Express, which is good because I don’t have much for woodworking tools.

It was a lot of fun, and they sound amazing. I keep saying I’ll build another kit...

As far as general advice?

You’ll need 4 clamps to do a decent job getting the box square.

Finishing the box is probably the hardest part.

And don’t get all worked up on getting the most amazing solder in the world when you build the crossover because it likely won’t make a difference.

I did a kit around 7/8 years ago. I bought the kit from Zalytron with the cabinets made as I don’t have the kind of tools to turn out something I’d be happy with. The kit used Focal drivers with Hiqquphon tweeters. They made the cabinets in doubled up 3/4" MDF to avoid needing braced. While that’s not a bad thing it made for a heavy speaker.

In short I say go for the premade boxes.

I used to do this a bit as a hobby. I mostly enjoyed the engineering, testing, tuning - you know, crunching the numbers. I was less concerned about the final appearance, and more concerned about the performance. If you are doing it from scratch, use medium density fiberboard for the box, glue all the joints and make sure it is airtight, and don’t forget the insulation (dampening). There are some good books out there on speaker design and construction, although I am sure all of mine are waaaaaay out of date... just like the guy offering the advice...

There aren’t any premade cabinets for the speedsters...but I would have to make it from scratch during winter break...

I made these... http://oppositelock.kinja.com/best-thing-to-do-with-old-jerry-cans-1705696070 And I’ve redone these and some old Klipsches http://oppositelock.kinja.com/audiolopnik-the-follow-up-1535550988 And I messed around like a basic girl on etsy with these http://oppositelock.kinja.com/speakerlopnik-the-new-project-1708068985

That last point, though!

I have, but it’s all been custom work as a hobby. I have a few books on designing the sound chambers, sometimes I got it right, other times not so much.

My best advice for a start, get on craigslist and buy a ratty looking set of vintage speakers that work, and spend your time building new cabinets first. Typically the drivers and crossovers are well matched, you will get to see everything inside that is involved, and practice with cabinet making and different looks, etc.

Then go full on custom after you figure out what you like and don’t like, etc.

Seriously, when I bought the kit and read the reviews there were tons of recommendations about this solder or that solder or using  the other solder but only with components from a certain brand ...

I don’t doubt that there’s some difference between one solder and another, and that this difference is measurable with the finest of fine electronic instruments, but audibly - no-one will ever know.

In the end, I bought a nice solder that was a reasonable price, and then my cheap soldering iron couldn’t melt it... so I used the cheap stuff that was already in the toolbox!

Oh, I know. That same scenario goes on where I work constantly. At the low power levels and temps in audio components, almost any solder will do.
