First Build SX212

#1 Post by Jgriff »

First build. A Simplexx 212 from a Speaker Hardware flat pack w/ 3012HO drivers. It was a lot of fun to build. The one big mistake I made was not following the plans and using T Nuts for the speaker mounts. A couple stripped but hopefully it won't cause too many issues. 55 lbs.

Nicely done.....how in the world did you strip out T-nuts? I used those on my first builds, but with Neo drivers, it's just not necessary anymore.

TNuts used to be made much better than they are today. I stopped using them quite a few years ago,

I learned my lesson and won’t use them again. The T nuts stripped the surrounding wood and just spin. Just plugged it in and it sounds fantastic. Much more lively sounding than the pair of SVT 112AVs I have been using.

I'm guessing you used hurricane nuts and not T-nuts. T-nuts have prongs that you drive into the wood so they don't spin. I though you meant you stripped out the threads inside the nuts.

I use them quite often in other projects.....

Hurricane nuts.....will spin without epoxy.

T-nuts ....... hang on quite well....

However, you can stop hurricane nuts from spinning. On the flange, drill a small hole and use a small screw to lock it into the wood.

I had problems with the prongs bending, so the nuts would spin, and with stripped threads as well. Hurricane nuts were better, but still not perfect. I figured if someone with my experience had trouble with them that I didn't want to recommend them to less experienced builders, so I devised a way that's near impossible to screw up.

Driving the prongs into BB can be a little tough, but usually not an issue. You can always give then a tap then pre-drill 'em just a little bit. I'm sure there are different quality T-nuts also....

But, not really necessary on your cabs. I haven't used 'em in a cab (for speakers) since my T39s. I have used 'em for other projects - most recently on my Princeton cab that I built. I get tired of screws coming out of rubber feet on cabs, so I used the T-nuts for the feet.
Also for the handle on top. They have their place.

It's hard to get the recex screws (at least I can't find 'em), so I've been using lag screws with lock washers.....works great and the hex head lessens the chance that a screw bit on a drill/driver could end up going through a cone.
