Oooohhhh! I see now...it was those washers that were confusing me.

Sooo....first step. Trace the spots where teh holes go. Then drill a small pilot hole. Then place the flat end on the inside, yes? And then use the screw with the washer to pull the hurricane nut into the wood. Yes? This sounds right. Is that how I do it? Hehehe...Im having a silly, scattered morning.

Are the mounting blocks made of MDF or wood? If MDF, the T-nuts or Hurricane. If wood, you can use screws. I used wood, so I screwed them......that sounds funny.

Hehehe....yes, Vitod, those extra blocks I added were made of MDF.

I second the idea of gluing the backs on, especially if they are t nuts. Once one falls out it is a major pain to take the driver back out and find it.

Should be pretty easy to get those in. I plan on setting them all tonight if I can. Since two of the sides arent on and neither are the baffles. I should have really easy access to the back and front of the baffle.

Phew! Been a while since Ive updated this...

Spent all of last weekend cutting and fitting both cabs with R13. Got two bags and they just about covered them.

Heres everything all filled and stuffed.







Ran into trouble regarding the extra support blocks I made for the woofer. They all failed. I mean, they were on there but most of the hurican nuts tore into the wood somehow. They werent very secure. Some turned when trying to insert the mounting screws....ugh! What a nightmare.

So here they are not...heheh....they broke off with little effort...what a shame.



So I talked to my uncle and he recommended "real" wood. I forgot what kind it was but he also suggested that the hurricane nuts be slightly recessed into the blocks. That worked out cause the the screws didnt make it through two layers of 3/4" MDF oddly enough. After I got a sample I asked for a whole batch. Half hour later Ive got a whole bucket of these from my uncle (thank you very much) and we got right back to getting these baffles all ready...

While all that was gluing over night and such...

I got a tip that I needed extra support in the front to back direction. So I added the extra support between each brace. I did this a bit ago but hadnt updated the thread. At this time I needed to add one that combined the baffle to the front most brace.

These...







You can see them pretty well in the last "lined and stuffed" pics and this one with my buddy, Dan. (not of AVS fame)

Earlier this week....trying for a baffle fit. Fits great!

With the final side on...and those clamps...we were unable to move this thing, just the two of us. It took some effort but we got it onto a dolly for setting aside for the time being. *drying* Super, super heavy.



A 16 fl oz glue bottle on this sucker....for scale.





Going to be sanding down all the rough edges from glue and such tonight on this one....also closing the second cab tonight if all goes well.

Wish me luck!

Now that is HUGE People can say what they will about big sonosubs, but I'm convinced they are much less visually intruisive, whether for better or worse. So how are you planning on getting those into place?

UPDATE!

Ahahaha! Finally conquered the second box!



All this week I have worked on sanding and trimming here and there. Got the side onto the second box. So now I have to sealed up cabs!

Here they both are....(2 liter bottles for scale)



Got them all sanded, routed, and primed yesterday!



Heres my friend, Dan (not of AVS), taking a break and gawking at the size of these suckers.



Both primed except for the back of the cab thats closest to the camera. These are so big you cannot see Dan hunched behind them painting the last back.



Dan is behind it still in this one but you cant see him.



Primed from all sides...

And here are the 'twins'....just resting for the evening.







So excited! Gonna do a little 'touch up' on them later today. Mostly on the corners where the primer really gets soaked up. After I am happy with the results (so far I am!) I will start doing a coat of black paint tonight. I figure a good two coats will do it. I'll just have to do it and see....

Steve Callas says: Now that is HUGE People can say what they will about big sonosubs, but I'm convinced they are much less visually intruisive, whether for better or worse. So how are you planning on getting those into place?

Yeah...they are waaaay fricken' huge! Ridiculous, is what we like to say while working on it... They move around just fine on a standard dolly. Thats how we move them around now. Getting them inside shouldnt be a chore. Ive measured and these will easily make their way into the HT. Its stacking one on top of the other that will be the challenge. Gonna have to enlist all the strong hands I can on "moving day".

Almost there....

Predicting the earliest this is finished and into position ....tomorrow. Otherwise, Sunday or early/mid next week.

Can you imagine how cool it would look if it was all veneered..... It would take two trees to cover up those bad boys!

Those subs are so intimidating, I'm jealous.

My original idea would have been to veneer them. But...with costs running up and up as the build went on. And my lack of real woodworking skills....I had to nix the veneer job. They will be nice, flat black...tucked away in the corner.

wow nice work i have a website that have some diy stuff and if you are interested i'd love to publish your work with complete drawings?

Look at these suckers next to a 55" Hitachi RPTV!!!


Ahhhh.....I love the "new" corner to my HT.



And the new color to the room.



And I love my speakers in black....so much better. No reflected light from them anymore. The picture quality improved from the dramtic reduction in reflections. And the room is much darker now. When the lights go out, the speakers become invisible!

Whew! So I had them installed about midnight Saturday night. So obviously, I couldnt "play" with them. I simply listen to some music...really low level, just to see it they work. Played with them for only a couple hours on Sunday (it was my Uncle's birthday) and all I have to say is.....HOLY COW! I barely got them louder than my Tempest so far (taking it easy) but they sound incredible! Can't really test out the deep, deep extension yet. I dont think they are fully broken in yet....that will take some time. Like I said, I barely got about 2-3hrs in with them.

Today will be fun.

FUKEN NICE!!!!!!!!!!!!!!!

welcome to the darkside!! now get some measurements on those badboys ASAP shorty!
post #170 of 398
Wow... Those sure look fierce!

Are you going to paint inside the ports?

I can't wait to hear your impression when you get to crank them up full bore. You might wanna pickup a bucket of drywall spackle next time you goto Home Depot!

OMG!!!!

Build another two and put it in the other corner!

Yes, you should definitely paint the inside of the port. Those are really awesome. I love how big they are.

Since you didn't round the edges of your ports, let us know if you get any turbulence noise.

Now CRANK em up and let fly!!!

Ssabripo - "FUKEN NICE!!!!!!!!!!!!!!!

Heheh...sure does feel good. I was gonna wait a little while to actually take some measurements. I wanted to break em in real good for a bout a week or so. All I have is an older style analog RS meter. Annnnddd I just got REW a little while ago, maybe Ill just try that first. Should be more accurate than if I were to plot it manually. I'd say in the next week or two will I do some measurements. Im still trying to get used to them.

Vinculum - "Wow... Those sure look fierce!

They sure are mean lookin'! So far I am the only person that doesnt care much about the color of the ports. The the flashed pics exaggerate the brightness of them. And when the lights are out, you cant even see the subs. Ill probably paint them in the near future. I still have to touch up the paint on the outside of it. You can still see the cardboard edge under the glue.

So far I have done quite a few "demos" here and there today. A little Star Wars (pod race), We Were Soldiers, U571, Titan AE, Matrix, Matrix:Reloaded, Pearl Harbor, Open Range, Superman Returns,Xmen Last Stand, opening to LotR, ID4...to name a few. Yesterday I touched some of those at levels that were comparable to the max output of my single 250w Tempest. Obviously at much, much lower distortion levels. Sounded so effortless. Scenes that previously used to clip the plate amp would play with such ease. It was quite a sensation.

Today I flirted with the max output of these...accidently left it +6dB on Xmen3 from watching open Range and that was the only time I heard the slightest peep of strain. Very loud transients were reproduced just fine but I think I heard a noise on a couple of loud booms. Other than that....spectacular performance so far! So far my favs are still good. Others take on a new a new life. The thunder from Open Range is so realistic, I wanted to look outside and check if there was a cloud cover. Most realistic recording of thunder Ive ever heard. Awesome stuff!

Crackyflipside - "OMG!!!!

Build another two and put it in the other corner! "


Ack! Don't tempt me! Ive heard plenty of "Omg's!" when friends/family look at these not to mention the "Omfg, no's!" Ive heard when I mentioned that I might want two more. Cause I already know...I do.

I think I am a little insane though, so its all cool.

Mmmm....I could say then that I have," +6dB'd myself into submission."

Video - "Yes, you should definitely paint the inside of the port. Those are really awesome. I love how big they are.

Hehehe...actually, I dont think they ever will. I specifically designed this to almost never have port turbulence. It was an 11hz tune. Ive modeled it out and even with 650w into each one the port speed just barely gets above 30 m/s. And that is only between 7-12hz. So far I have tried all sorts of ridiculous <16hz material into them at many volume levels and have heard zero port noise. All sorts of movie and music mind you. One song I play has a very strong, sustained <9hz material with loud sustained 12-18hz stuff after. No a single peep from the ports. Ahahah! I love it!

Thats it for now...Ill have many many more impression on the way. I still have to pop in the DTS versions of Saving Private Ryan, The Haunting and *duh duh duh* WotW.

(acutally, I forgot to mention I have played ch5 from WotW already. Lolz! It sounded wonderful! Now I just have to do it again...only louder. )

Me + a friend + dad and uncle = lifting power!



It actually wasnt as hard as I thought it would be. We had one on a dolly so we could grasp the bottom of it. I stood at the back, my friend at the front and my father and uncle on one side. My aunt stood close and was our eyes while we picked it up and gently placed it on top of the other sub which we had positioned into the corner.

I hope this is in a house and even then the neighbors are gonna go nuts hahahahahah

Hehehe...yes, this is a house. I could never put something like this in an apartment. Lolz!

With my Tempest, which I would play as loud as I could...I could barely ever hear it outside. Almost nothing. I used to occasionally play music loud into the late late morning. After 1-2am ...and nothing from the neighbors. In fact, this room is the closest to the neighbors and still, nothing. Pretty sturdy, semi-soundproof house, I guess...

That is...until I open a window.

I know plenty of people having walked/driven by our driveway while I have been building these. I guess these neighbors aren't that interested.

WOOOOOOOOOOOOOOOOOOOOOOOOOOWEEEEEEEEEEEEEEEEEEEEEEEEEEEE

Congratulations! These mean machines sure are HUGE,just like a real sub should be. Once you taste real DIY...no way back to the whimpy side of subing.

Damn O damn,now I have to get muself dual RL-p 18" and build something like this,ported monsters.

Again WOW... your mains look like microscopic sats from a HTIB system next to the stacked brutes!

What TV do you use a 14"?

Hahahahaha! Thanks!

For sure, I tasted the fruit of DIY years ago and I am never turning back. Totally! You should build some of these. Heck, build four! Why not? You have a 100 subs at your home already. What would a quad of these change? ....hehehehe....thats just sick.

Congratulations on a job well done! Those are some GINORMOUS subs for sure. I'd love to hear Master and Commander through those, at scare your friends volume of course.
