All I know at this point is 1) that's a great idea to route in the groove. And 2) I need to cut a lot of circles. biggrin.gif

Lol.. That was my thought from the first! I hate to build more than one at a time. When I do, I build them all at once the same as you're doing. It sort of takes the fun out of it though. Think of the $$ your saveing though. We never count our time over here. It means nothing! lol wink.gif

Measured mine last night. The lip is 1/4" without tape.

I meant 3/16" deep, thats half of 3/4" which is the total thickness of the MDF. Going 1/2" deep seems like it might leave the out portion to prone to breaking.

I enjoy this and saving money is just a bonus. However I have no shop. im outside and summer days left are counted easily on two hands.

I was thinking of taking a quick stop to put a roof up under my deck, but of course the deck was built just as whacky as some parst of our house. It has a support beam in the middle, not at the end like most upper level decks, smack dab in the middle. Easily do able still, but will add time and cost to the project.

HAHA.... Trying to talk the wife into going ghetto style and just throwing a large tarp on top of the deck for thw winter.

Daddy wants a new table saw too. biggrin.gif

Yeah a 1/4 seems right. 3/16 deep should be fine, I just randomly thought of it and suggested. I forget how deep I went and yours is a larger diameter, you wouldn’t want to see routering to go to waste! rolleyes.gif I, as you, would hate when that happens.

HeHe, a tarp over the deck! I like it, and a new saw! There go the friendly CCR’s down the drain. Hun! will you look at what that pdx guy is doing eek.gifbiggrin.gif

It's a great idea and will further seal/seat the end caps.


We are one block outside the largest HOA on the west coast. 4-500k homes, and most take very good care of them. Including my neighbor who decided he would park his boat in his front yard. Notice there is no driveway in front of that boat? LOL :eek

I have bigger problems besides the neighbors and the HOA....... wink.gif

That’s hilarious! I see that boat behind the bush. He has 2-3 days I bet by rights. I sort of wanted to say more in my last post but this is your thread. smile.gif Anyway I have a great time goading my best friend for the last 30+ years. He is just the opposite of me. When he built his house he was sure not to have to deal with CCR’s. He has like 4-7 cars in front of his house at all times in different forms and shape. It’s nothing for him to have a big-block engine sitting in his yard. He has four kids so that ads to it also. Anyway we always have a good time playing regarding the subject. After having to retire 10 years early to come home and take care of family matters, I’m back on the farm as they say. No one to deal with and do as I please. I wake up in the morning and go outside for a cigarette and take a lxxk while I’m at it. smile.gif This is the first time in my life that my bass doesn’t bother anyone..

I managed to get four 25" squares cut and then ran out of wood. My trailer is half full of junk so I filled the rest of it up and need to hit the dump first thin in the morning.

Shortly after I realized that needing 24" circles x 16 just for the plugs is a lot of sheets of MDF.

I can get 4 a sheet if I cut two 12.5" pieces and router out half circles then screw and glue them to a full circle. This is if I use a double plug cap in each end of the tube. I think this will be OK if I sandwich it between the first plug and the top cap.

Then I still need 8 26" squared for the top caps.

Six sheets of MDF. I hate MDF.

How important is it to put two circle plugs in the end of the tube.... vs. just one and the top cap?

You only need to double up on the baffles (Plugs?? Haha). one 3/4" interior of the tube, one 3/4" exterior with the lip, so that is only 16 total circles to cut, plus 6 more for the woofer cutouts

So you're saying to double up on the exterior of the tube vs. what I was saying which was double up on the inside of the tube?
post #68 of 268
No, no. Double up on the baffle TOTAL, so just a total of one inside, one outside, or two circles, or 1.5" of material. Any more than that is not really needed with a D.O. type build since the tubes are going to be completely inert.
post #69 of 268
Baffle.. the base that sits on the floor.. then spacers, then the two rounds that actually make up the baffle. I’ll see if I can find pic. Whoops! or you can choose not to go with a base, much simpler. smile.gif

Got it. Your 'six more circles for the subs' threw me. Really that's 12 more because I have to cut circles out of the interior layer as well.

But in terms of total sheets, that's a changer...

Ya Im not going to do a base, just closet hanger dowls.

When flush mounting the driver do you sink the driver all the way down to the first plug, or baffle lol, 3/4" or no?
post #72 of 268
Are you going the base rout or will your subs be sitting on legs. I have one possibly two extra layers here that you don't have to go with. Edit> I see your new post.. no base









post #73 of 268
Looks like I inseted mine. You should be fine doing the same thinking about it if that's the way you want to go? You could do flush also, it would ad strength.

Thanks for the pics, Steve. They look great!

That was exactly my plan. You have two inner layers and an outer layer. You routed out your outer most layer to sink the driver 3/4" and attach it to the top most inner layer.

Whether I do one or two inner layers I will sink the driver as you did. Right now I'm thinking that on the top of the tube I will go flush with the tube and route the corner to make it look nice.

Might go a little wider on the bottom outer layer for stability, but I'm not sure that's needed.

I also might come out a 1/4" if I decide to wrap the tubes in carpet.

If I am super slick with the router I can get exactly 8 24 and 1/4" squares out of a sheet. biggrin.gif
post #75 of 268
Yes as far as the top goes, I accounted for the covering and added that to the width of the groove in the very top cap so it would all seat in well as the bottom. You bring up a good point about the bottom being larger than the top because of stability. I don’t think it is called for, especially since yours is even larger diameter wise and shorter. My very bottom base is the same size as the top and I can practically lean up against it no problem on account it’s so large to begin with. But of course any added diameter is going to ad stability. Yours will be on legs also, so one might want to account for that. Some of these decisions have no right or wrong answer, it’s up to you. Can’t figure out how you’re going to get 8 – 24” squares out of a 8 X 4’ but I’ll pray for a miracle so that sheet goes a long way. biggrin.gif

HA! The sheet is 49x97 that leaves 4 24.25" squares per sheet of MDF. I will have an 1/8" of scrap after each circle. The only thing that will screw me is the width of the damn saw blade, leaving my squares less than 24.25.

I think I can swing it with the inner caps.

Well so much for that....

I measured them out at 24.5" on accident and it's probably for the best. Six caps per sheet isn't bad and it's far less pushing my limits than trying to router out 24" circles from 24.25" squares that would be short a tad from the saw blade.

I'll have to grab more MDF I"m going to go two inner caps and one outer. Why not.....!

LOL.. two inner caps now!.. smokin! Yeah it’s easier to router out the circles while in the full sheet but then that brings up other issues. That’s what part of DIY is about, friggin-fraggin ISSUES! tongue.gif

I was going to do two inner sheets from the get go, based on past reading, until BeastAudio came in and confused me...... again!

haha.... giving you hard time beasty, your help and input has been invaluable not only for me but tons of other posts I've read in others builds etc... smile.gif

I love to overdue things and push the limits so I almost would have lost sleep with only one layer inside the tube.

I think for someone who hasn't touched a router since 8th grade wood shop, that starting out with squares will be easier than using a full sheet. Especially since woodshop was taken in place of math. wink.gif

Check out page 1. I got 15 of the 16 needed squares and 3 of the 8 needed caps. I'm going to aim for 24.5" for the top cap circles. That should leave a 1/4" overhang. You all think that will be an issue since I want to round the top and bottom of those plates?

I don't think that will leave enough room for that brilliant idea of a groove to sink the top plate onto the tube, but it might. I'll have to feel it out when I get there.

So I have a few more squares to cut and then I'm just waiting on the router.

Oh yes..... on another note I bought a new 24 tooth blade tonight for my little cordless Ryobi 18V circular saw. I thrashed my last one the other night cutting nails. Dumb.. mad.gif

My 'other one' was an 18 tooth. I should have gotten another 18 or 16 tooth. The 24 tooth just doesn't 'cut it' (no pun intended) for MDF. Batteries drained quicker and the blade feels like it's getting worse with every cut.

Heads up for anyone who reads this and might be in the same situation.

Worst decision I ever made was to sell my worm drive skill saw. That thing was a dream. I could rip 2x6s' with one hand holding the board and the other the saw. Not to mention uber accurate cuts on anything else.

I would do 1/4 on both sides of a piece of scrap and see what you think of the profile. It might be best to just relieve the edges in your case?

Howdy smile.gifsmile.gif

I am honestly glad to meet / to know there are local people that are into this same hobby as I am. I always thought it was kind of dead up here in the NW when it came to audio and speaker building.

Yeah that’s something! When I saw your post my jaw dropped. I think it was about 15-20 years ago I sold a sub to someone I met on the forum from our area but that’s it. My passion has allways been sw’s but of course I like good speakers.. never have built any though. Anyway very nice to meet you thucker.

That's a good idea.

I like the profile of the ones you posted earlier in this thread. They look almost rounded.

That might come in a little more aggressive than a 1/4. Go easy on a piece of scrap and decide from there. I would hate to see you take to much off with such little room to play with..

Well PDX how is the routering going? Are you making any headway? What did you end up going with? 1/4-3/8 or 1/2?

Still waiting on the router. It was sitting around not even shipped as of yesterday so I contacted Amazon and upped it to two day shipping. Will be here Friday.

When doing corners will I use a 1/4 bit to get a 1/4 ? Or a 1/2 to do a 1/2? Or is it free hand?

1/4 will do a 1/4 radius and so forth. So that’s a 1/4 deep with a 1/4 radius. The router will guid you, will explain more latter. Got to go to HD. rolleyes.gif
