Sorry Mike if my response read a little snippy, I am unable to go back to my friends for the table saw and I am on my days off I have to get this done so I will have to make due. I picked up the PL Premium, it worked well on my F20 and I feel more comfortable with the amount of open time I will have with it.

Well I got a lot less done than I had planned today! Oh well......

 

So I clamped up a test fit so I could lay a baffle on top and trace out the cutouts:

 

 

 

I bought a 3.5" Hole saw to make it easy to cut out the holes for the ports.....hahah easy huh, man it took a long time for that hole saw to make it through 3/4" of MDF, the hole looks nice but I am wondering if its worth it as its going to be behind the baffle any way I am thinking the others will be a lot quicker if I just use the jig saw.

 

 

 

 

So the other reason I bought the hole saw and what took me way to long without a table saw was cutting these six squares for window bracing! (ChopsShops fault :) ) I plan on using the hole saw to put five circles in each one and was going to round over the circles edges. But now I am having second thoughts being is the hole saw takes so long I might just jig saw four windows in each and call it a day.

 

 

 

 

 

I plan on putting a brace between the wave guide and the woofer and the woofer and the ports, so two per box, will this be sufficient bracing?

Should be fine that is where I have them on my 12" box though it is a bit shallower at 1.6 cuft. If you want you can try to run a vertical brace or two, the one on mine does not do all that much between the top and first brace. I had different ports which made it harder to install a vertical brace to the bottom.

Thanks MTG, I will look at running vertical bracing as well. Do you think it will be critical if I don't though?

Again not as much progress as I hoped. I spent a bunch of time trying to make the window braces and gave up. I had cut the pieces to short and then trying to cut out the windows with the jig saw did not work as planned so I picked up some 1x2 Poplar and am going to go with stick bracing. I needed more clamps so made a second trip to the hardware store. Cut out the rest of the port holes, woofer, and waveguide cutouts on the inner baffle for this box, the jig and hole saws worked well here.

 

Behold the first glued and clamped and brad nailed box!

 

 

 

I am glad I went with the PL as it is filling the gaps nicely. All though as I was clamping things up some of my boards were sliding around a bit, took a few adjustments to get it aligned. I used the air nailer about every 4 inches, how long should I wait before un clamping with the PL and brads?

Worked on the crossover layout tonight, 

 

Are the inductors orientation ok? General Layout? I will be making the connections under the board.

 

 

 

Thanks guys

All these build threads are making me want to start another build! Unfortunately I can't find a good reason to give the wife.


Looking good so far! That was nice of your friend to do the cuts for you.

Ideally the hole in the middle of an inductor shouldn't be pointing right at another inductor. Can you twist the one on the left 90 degrees so it faces "up and down" in the picture?

Thanks! Your Stentorians look amazing, I can see why you wouldn't have a good reason! Maybe smaller SEOS design for garage speakers lol!

 

Yes it is was nice of him, he is really getting into wood working and got this great table saw, learned a lot about how to use it too!

Thanks for the feedback Antisuck and Mrkazador.

 

How does this look then?

Looks good to me, I go off the same diagram mrk posted (study by Troels Gravesen IIRC). Although I see bwaslo posted in another thread this morning that a similar layout was fine, and he is far more knowledgeable than I am. I'd still say better safe than sorry and certainly no harm done making the change.

Sounds good, I failed at doing nice bracing for my cabs so I want to make accurate and nice looking crossovers at least :)

Haha doing penance for non-pretty bracing? Take heart, more than a few folks would applaud you for not wasting material and box volume on braces that aren't any more effective than what you ended up with.

No problem. smile.gif Did not know that you would have to pack the boxes back to a friends house. In that case, use the PL and be done with it.

To cold to work outside in the garage and want to make sure the PL sets well so I decided to work on the crossovers.

I have to say I am very very happy with my first ever crossover assembly!  So happy with it that I pulled out the DSLR to take worthy pictures!

Thanks for the compliments fellas!

No pictures since its all the same stuff but I have the last box glued and clamped and nailed. Also put the bracing in the second box. I am going to let the third box dry overnight again and then do its bracing and glue up the front baffles on all the boxes, then finish prep!

XO's look great.

I'm glad I'm not the only one with multiple cans of chicken stock from Costco in my pantry.

Thanks, that's funny you commented about the cans, I was laughing about it myself when I popped them out for crossover assembly!

Made good progress yesterday!

 

Here are all three as they sit now, all baffles were added to the boxes, NO MORE CLAMPING :) !!!

 

 

 

They are each in various finishing stages, the one on the right is just glued up, the middle one has had all the edges sanded flush, and the left one the same plus filler waiting to be sanded!

 

 

 

 

 

 

Also bought a new tool which is really speeding up the finishing process!

 

 

 

The best thing about it is you can attach it to the shop vac to suck up all the MDF dust as it goes!

 

Ok off to work on these some more!

Keep it up! I have to admit, one of the best parts of these projects for me is an excuse to buy more(or better) tools.

I'm very excited to see the finished front soundstage as well as your listening impressions. I may have missed it, but what will you be powering these with? What are you using for your surrounds?

Also... In the past I always had issues with getting a good finish on MDF. I finally did some research and found out that MDF and water based paints/primers don't get along very well. On my last build I used an oil based primer and sanded between coats - made a world of difference!

I'm not sure how you plan on finishing these but figured I'd but in my 5 cents in case you do plan on painting.

edit: My bad. I just re-read your post about the duratex or primer and paint. ooooops!
